     TECHNICAL FIELD 
     Systems and methods are disclosed with respect to using a blockchain for managing the subrogation claim process related to a vehicle accident, in particular, utilizing historical data related to a vehicle or vehicle collisions as part of the subrogation process. 
     BACKGROUND 
     The insurance claim process may involve a tremendous number of communications and interactions between parties involved in the process. Potential parties to the claim process may be insurance companies, repair shops, lawyers, arbitrators, government agencies, hospitals, drivers, and collection/collections agency. Sometimes the costs of repairs may be disputed and parties may pursue subrogation for particular charges. As an example, when an insured person suffers a covered loss, an insurer may pay costs to the insured person and pursue subrogation from another party involved in the loss. If an insured vehicle is involved in a collision and suffers a loss, the insurer may compensate the vehicle owner according to an insurance agreement. If, for example, the vehicle owner was not at fault in the collision, the insurer may pursue damages from another party, such as the insurer of the party who was at fault in the collision. An insurance agreement may include an obligation of an insured to assign the insured&#39;s claim against a party at fault to the insurer, who may then collect on the claim on the insured&#39;s behalf. 
     Settling a subrogation payment may be a lengthy, complicated process. The various parties (e.g., parties at fault in a vehicle collision, owners of the vehicles, insurers, etc.) may need to exchange information relating to the collision to determine which party was at fault. Sources of information relevant to a fault information and/or subrogation payment may include information regarding parties involved in a loss, forensic data regarding the loss, vehicle data regarding a loss, etc. The various parties may verify and share information from a variety of sources, including information held by parties involved in a loss and their insurers, and information obtained from third parties (e.g., governmental entities, independent contractors, etc.). 
     The parties to a subrogation payment (e.g., insurers) may make proposals to one another to settle the subrogation claim. A proposal may include an accounting of damages, such as the costs to a vehicle owner whose vehicle was damaged. If an insured person suffered an injury in a collision, the injured person&#39;s health care costs may be included in the accounting of damages. One or both of the parties to a subrogation claim may rely on independent third parties to assess costs, such as a repair cost estimate by an authorized automotive repair services provider for damage incurred in a collision. To settle the subrogation claim, the parties may indicate acceptance or approval of damages calculations, and a payment amount agreed upon between the parties to settle the claim. Parties may rely on a third-party intermediary to handle subrogation negotiations and resolution (e.g., validate information relating to a loss and facilitating communications between the insurers) at added expense. 
     BRIEF SUMMARY

     DETAILED DESCRIPTION 
     Traditionally, businesses, customers, and central authorities, such as those involved in an insurance claim, have stored information related to transactions, and records of transactions, in databases or ledgers. Often these databases and ledgers are held by the participants and may be reconciled to achieve consensus as to the validity of the information stored therein. Alternatively, a central authority may be responsible for determining the validity of information stored in a database or a ledger, and functioning as an arbiter of consensus for interested parties, such as a recorder of deeds, an asset exchange, etc. 
     A blockchain (also referred to herein as a distributed ledger or a shared ledger) may be a way of achieving a distributed consensus on the validity or invalidity of information in the chain. In other words, the blockchain may provide a decentralized trust to participants and observers. As opposed to relying on a central authority, a blockchain may be a decentralized database in which a transactional record of changes to the ledger may be maintained and validated by each node of a peer-to-peer network. The distributed ledger may be comprised of groupings of transactions organized together into a “block,” and ordered sequentially (thus the term “blockchain”). Nodes may join and leave the blockchain network over time and may obtain blocks that were propagated while the node was gone from peer nodes. Nodes may maintain addresses of other nodes and exchange addresses of known nodes with one another to facilitate the propagation of new information across the network in a decentralized, peer-to-peer manner. 
     The nodes that share the ledger form what is referred to herein the distributed ledger network. The nodes in the distributed ledger network may validate changes to the blockchain (e.g., when a new transaction and/or block is created) according to a set of consensus rules. The consensus rules may depend on the information being tracked by the blockchain, and may include rules regarding the chain itself. For example, a consensus rule may include that the originator of a change supply a proof-of-identity, such that only approved entities may originate changes to the chain. A consensus rule may require that blocks and transactions adhere to format requirement and supply certain meta information regarding the change (e.g., blocks must be below a size limit, transactions must include a number of fields, etc.). Consensus rules may include a mechanism to determine the order in which new blocks are added to the chain (e.g., through a proof-of-work system, proof-of-stake, etc.). 
     Additions to the blockchain that satisfy the consensus rules may be propagated from nodes that have validated the addition to other nodes that the validating node is aware of. If all the nodes that receive a change to the blockchain validate the new block, then the distributed ledger may reflect the new change as stored on all nodes, and it may be said that distributed consensus has been reached with respect to the new block and the information contained therein. Any change that does not satisfy the consensus rule may be disregarded by validating nodes that receive the change, and may not propagated to other nodes. Accordingly, unlike a traditional system which uses a central authority, a single party cannot unilaterally alter the distributed ledger unless the single party can do so in a way that satisfies the consensus rules. The inability to modify past transactions leads to blockchains being generally described as trusted, secure, and immutable. Third party intermediaries who assist in the resolution of subrogation claims may thus be disintermediated from the process by a decentralized blockchain. 
     The validation activities of nodes applying consensus rules on a blockchain network may take various forms. In one implementation, the blockchain may be viewed as a shared spreadsheet that tracks data such as the ownership of assets. In another implementation, the validating nodes may execute code contained in “smart contracts” and distributed consensus may be expressed as the network nodes agreeing on the output of the executed code. 
     A smart contract may be a computer protocol that enables the automatic execution and/or enforcement of an agreement between different parties. In particular, the smart contract may be computer code that is located at a particular address on the blockchain. In some cases, the smart contract may run automatically in response to a participant in the blockchain sending funds (e.g., a cryptocurrency such as bitcoin, ether, or other digital/virtual currency) to the address where the smart contract is stored. Additionally, smart contracts may maintain a balance of the amount of funds that are stored at their address. In some scenarios, when this balance reaches zero the smart contract may no longer be operational. 
     The smart contract may include one or more trigger conditions, that, when satisfied, correspond to one or more actions. For some smart contracts, which action(s) from the one or more actions are performed may be determined based upon one or more decision conditions. In some instances, data streams may be routed to the smart contract so that the smart contract may detect that a trigger condition has occurred, and/or analyze a decision condition. 
     Blockchains may be deployed in a public, decentralized, and permissionless manner meaning that any party may view the shared ledger, submit new information to be added to the ledger, and/or join the network as a validating node. Other blockchains may be private (e.g., permissioned ledgers) that keep chain data private among a group of entities authorized to participate in the blockchain network. Other blockchain implementations may be both permissioned and permissionless whereby participants may need to be validated, but only the information that participants in the network wish to be public is made public. 
     The present embodiments relate to, inter alia, systems and methods for using a blockchain to record and manage information related to resolution of a subrogation claim (e.g., a “subrogation” blockchain). The subrogation blockchain may be either a public or permissioned ledger. In particular, certain embodiments discussed herein relate to the use of “evidence oracles,” as part of a subrogation blockchain. These evidence oracles may interact with the blockchain and send information, such as evidence related to a subrogation claim, to the blockchain. 
     Exemplary Shared Ledger for Resolving Subrogation Claims 
       FIG.  1    depicts an exemplary shared ledger system  100  for resolving insurance claims, and more particularly, subrogation claims in accordance with one aspect of the present disclosure. Participants in the shared ledger system  100  may be insurance companies  106  and  108 , repair shops  122 , lawyers  144 , arbitrators  140 , government agencies  124 , hospitals  120 , vehicles  102  and  104 , collection/collections agency  134 , and evidence oracles  148 . The claims process may be problematic in many regards, such as identifying what evidence is related to, and valid for, a collision, determining proper subrogation amounts, and/or negotiating what line items each party is responsible for. 
     These problems, and others addressed herein, may be obviated through the use of a distributed ledger. For example, evidence oracles that record information occurring in the physical world may transmit that information to a distributed ledger where it can be used in the claims process. An automated recommendation engine powered by artificial intelligence may be used to suggest subrogation payment amounts. The line item negotiation may be done through transactions on the blockchain where all the necessary parties can see the information. Lastly, to facilitate the claims process, a connected vehicle involved in a crash may create its own distributed ledger, or update an existing distributed ledger with relevant information to the claims process. These solutions may be used for the claims process generally, or more particularly, for a subrogation claim process. 
     For a subrogation claim, when an insured party, such as the owner of not-at-fault vehicle  104  experiences a covered loss, for example in a collision with at-fault vehicle  102 , the owner of not-at-fault vehicle  104  may submit an insurance claim  110  to an insurer  106 . The insurer  106  may have a contractual obligation to remit a payment  112  (such as crypto or digital currency) to the owner of the not-at-fault vehicle in exchange for assignment of any legal claim the owner of not-at-fault vehicle may have against the owner or operator of at-fault vehicle  102  for damage and expenses associated with the collision. 
     After insurer  106  has remitted payment  112  (such as real dollars, or a crypto or digital currency) to the owner of the not-at-fault vehicle  104  and receive assignment of the vehicle owner&#39;s claim against the owner or operator of at-fault vehicle  102 , the insurer  106  may initiate a process of managing and resolving the legal claim against the owner or operator of the at-fault vehicle  102  or against an insurer  108  of the at-fault vehicle (e.g., a subrogation claim). The shared ledger system  100  may include a blockchain  118  accessible by network participants via a network  116  (e.g., a private or public packet switched network). To begin the blockchain subrogation claim resolution process, the insurer  106  may broadcast a subrogation claim or transaction  114  to the blockchain  118 . 
     The blockchain  118  may be a network wherein participating network nodes validate changes to a ledger based upon transactions broadcast by other network participants. The transaction  114  may include information relating to the subrogation claim that may be modified by subsequent transactions broadcast over the network  116 . In another implementation, validators on the blockchain  118  may be configured to maintain a state database and execute code in smart contracts deployed by network participants. A smart contract on the blockchain  118  may expose methods and maintain the state of data relating to a subrogation claim by the insurer  106  against the insurer  108  relating to an insured loss covered by the insurer  106 . 
     After a subrogation claim  114  has been lodged by insurer  106 , information relating to the covered loss may be collected by other parties that were involved in the collision to evaluate the subrogation claim. For example, a hospital  120  may broadcast a damages transaction  126  to the blockchain  118  that may include evidence of medical bills incurred as part of the collision. An automotive services repair provider  122  may broadcast a transaction  128  to supply information regarding repair services estimated or rendered as a result of the collision. A government entity  124  may supply evidence relating to the collision in vehicle transaction  130 . Vehicle transaction  130  may include information relating to one or more of the vehicles  102  and  104  involved in the collision relevant to the subrogation claim (e.g., registration status, registered owner, legal title information, police reports regarding the collision, driving records of the drivers involved in the collision, lien information regarding the vehicles  102  and  104 , etc.). 
     Evidence may also be supplied by evidence oracles  148  through the use of evidence transactions  150 . These evidence oracles may be devices connected to the internet that record information about the physical environment around them. For example, the evidence oracles may be connected video cameras, traffic cameras, road sensors, motion sensors, environmental conditions sensors (e.g., measuring atmospheric pressure, humidity, etc.), as well as other Internet of Things (IoT) devices. The oracles  148  may package their data into transactions  150  that are submitted to a blockchain. 
     When entities broadcast transactions to the blockchain  118  to initiate or add data to a subrogation claim, the transactions may be accompanied by a proof-of-identity of the entity broadcasting the transaction. In one implementation, a cryptographic proof-of-identity may be included in transactions sent to the blockchain. For example, each of the entities  106 ,  108 ,  120 ,  122 , and  124  may own private cryptographic keys that are associated with public cryptographic keys known to belong to the entity (e.g., public cryptographic keys associated with each of the entities may be published by a trusted third party or proven to other network participants, etc.). 
     An entity wishing to broadcast a transaction to the blockchain  118  may sign a cryptographic message in the transaction with the entity&#39;s private cryptographic key to prove the identity of the entity broadcasting the transaction. In this way, other network participants may be provided with cryptographic proof that the information contained in the broadcast transaction was originated by the participating entity. 
     After entities such as the hospital  120 , automotive repair services provider  122 , government agency  124 , etc. have supplied information relevant to the subrogation claim, the subrogation claim defendant insurer  108  may broadcast one or more subrogation transactions  132  to the blockchain  118  to indicate acceptance or rejection of the various components of the subrogation claim. For example, if the subrogation claim defendant  108  disputes that medical care provided by the hospital  120  was caused by the collision, and thus would form a proper basis for liability to the subrogation claimant insurer  106 , the subrogation defendant insurer  108  may broadcast a transaction marking the damages transaction  126  as disputed or not agreed. In response, the insurer  106  may broadcast a transaction  114  to respond to the subrogation defendant  108 &#39;s rejection, such as lowering the damages claimed as part of the medical costs incurred at the hospital  120 , adding more evidence of the nature of the medical services rendered by the hospital  120 , etc. 
     If the subrogation defendant insurer  108  accepts the damages associated with the subrogation claim brought by the claimant insurer  106 , the subrogation defendant insurer  108  may broadcast a transaction  132  to the blockchain  118  to indicate a resolution of the subrogation claim for the amount reflected by the blockchain  118 . Alternatively, or additionally, the subrogation defendant insurer  108  may broadcast a transaction to the blockchain  118  reflecting payment of the subrogation claim (including either real dollars, or a crypto or digital currency), and/or may broadcast a transaction sending a token having value that circulates on the blockchain  118  to the insurer claimant  106 . 
     Alternatively, one or more of the parties to the subrogation claim (e.g., the insurers, the parties to the loss, etc.) may demand resolution of the subrogation claim by a third party. In some implementations, parties may indicate lawyers  144  are desired to advance the subrogation claim, such as in a court of law for example. In another implementation, a third party who may resolve the subrogation claim on the blockchain  118  may be an arbitrator  140 . 
     Another third party that may be involved in the subrogation claim on the blockchain  118  may be collection/collections agency  134 . Upon resolution of a claim, the prevailing party may experience difficulty in collecting any judgment owed. As such, the prevailing party may indicate interest in debt collection services from collection/collections agency  134  in much the same way as the parties indicate desire for arbitration, or for lawyers to take the case. 
     Exemplary Validating Nodes in a Distributed Ledger System for Managing Insurance Claims 
       FIG.  2    depicts an exemplary shared ledger system  200  for managing insurance claims, including subrogation claims in accordance with one aspect of the present disclosure. The system  200  may include a shared distributed ledger  212 , and plurality of nodes  202 ,  204 ,  206 ,  208 , and  210 . Each node may maintain a copy of the distributed ledger  212 . As changes are made to the distributed ledger  212 , each node received the change via network  214  may update its respective copy of the shared distributed ledger  212 . A consensus mechanism may be used by the nodes  202 - 210  in the shared ledger system  200  to decide whether it is appropriate to make received changes to the distributed ledger  212 . 
     Each node in the system therefore may have its own copy of the distributed ledger  212 , which may be identical to every other copy of the distributed ledger  212  stored by the other nodes. The shared ledger system  200  may be more robust than a central authority database system because of the shared ledger&#39;s decentralized nature. As such, there may be no single point of failure on the shared ledger system  200 , as there may be in a centralized system. 
     Exemplary Transaction Flow &amp; Block Propagation Flow 
       FIG.  3    depicts exemplary validating network nodes and an exemplary transaction flow  300  on a shared ledger network for resolving transactions in accordance with one aspect of the present disclosure.  FIG.  3    includes two time frames  320  and  322  represented by the left and right sides of the dotted line, respectively, Node A  302  and Node B  304 , a set of transactions  308 A- 308 D, a set of blocks of transactions  309 A- 309 D, a distributed ledger  310 , and a blockchain  318 . 
     The block propagation flow  300  may begin with Node A  302  receiving transaction  306  at time  320 . When Node A  302  confirms that transaction  306  is valid, Node A  302  may add the transaction to a newly generated block  308 . As part of adding the transaction  306  to block  308 , Node A  302  may solve a cryptographic puzzle and include the solution in the newly generated block  308  as proof of the work done to generate the block  308 . Alternatively, a proof of stake algorithm may be used to generate the block  308 , whereby Node A  302  “stakes” an amount of a digital token used on the network, however, the network itself may determine the node that will mint the new block. In other embodiments, the transaction  306  may be added to a pool of transactions until a sufficient number of transactions in the pool exist to form a block. Node A  302  may transmit the newly created block  308  to the network at  312 . Before or after propagating the block  308 , Node A  302  may add the block  308  to its copy of the blockchain  318 . 
     The transactions  309 A- 309 D may include updates to a state database  316 . The state database  316  may contain current values of variables created by smart contracts deployed on the blockchain  318 . Validated blocks, such as block  308 , may include transactions affecting state variables in state database  316 . At time  322 , Node B  304  may receive the newly created block  308  via the network at  312 . Node B  304  may verify that the block of transactions  308  is valid by checking the solution to the cryptographic puzzle provided in the block  308 . If the solution is accurate, then Node B  304  may add the block  308  to its blockchain  318  and make any updates to the state database  316  as rejected by the transactions in block  308 . Node B  304  may then transmit the block  308  to the rest of the network at  314 . 
     Exemplary Node 
       FIG.  4    depicts exemplary components of a network node  400  on a shared ledger network for resolving subrogation claims, in accordance with one aspect of the present disclosure. Node  400  is capable of performing the functionality disclosed herein. Node  400  may include at least one processor  402 , memory  404 , a communication module  406 , a set of applications  408 , external ports  410 , user interface  412 , a blockchain manager  414 , smart contracts  416 , operating system  418 , a display screen  420 , and input/output components  422 . In some embodiments, the node  400  may generate a new block of transactions, or may broadcast transactions to other network nodes by using the blockchain manager  414 . 
     Similarly, the node  400  may use the blockchain manager  414  in conjunction with the smart contracts  416  stored in memory  404  to execute the functionality disclosed herein. The memory  404  may further include chain data  424  including, for example, a state database of the blockchain for storing state of smart contracts deployed thereon. 
     In other embodiments, the smart contracts  416  may operate independent of the blockchain manager  414 , or other applications. In some embodiments, node  400  may not have a blockchain manager  414 , or smart contracts  416  stored at the node. In some embodiments, the node  400  may have additional or less components than what is described. The components of the node  400  are described in more detail below. 
     The node  400 , as part of a decentralized ledger system  112 , or another decentralized or centralized network, may be used as part of systems that interact with and/or manipulate data and transactions associated with the automotive claims process, the vehicle loss history process, and/or the vehicle identification number lifecycle process. 
     Exemplary Smart Contract State 
       FIG.  5    depicts an exemplary smart contract state  500  in a shared ledger network for resolving subrogation claims in accordance with one aspect of the present disclosure. A smart contract may be deployed by any participant in the subrogation blockchain network (e.g., a subrogation claimant) to establish a contract state  506  for a particular subrogation claim. The deployed smart contract may expose methods and data to other participants in the subrogation blockchain network. Some of the data in the smart contract state may be private data that may only be altered by calling a method of the smart contract, or only altered by authorized blockchain participants. 
     One way of altering the smart contract state  506  may be to broadcast a transaction to the subrogation blockchain  502 . If the broadcast transaction satisfies consensus rules, network validators may include the transaction in a block  504 . Inclusion in the blockchain  502  of a transaction sending data to the smart contract may cause validating nodes to update a state database, thus allowing network participants access to a rich state mechanism to manage the subrogation process, and ultimately to resolve the subrogation claim. 
     Subrogation smart contract state  506  may include pieces of data to identify and track the subrogation claim. For example, a contract owner may select a unique ID for the subrogation claim such that subsequent transactions and data sent to the smart contract may identify the contract by ID number. The contract owner may also specify an identity of the subrogation claimant and defendant. In at least one implementation, the subrogation claimant and defendant may be identified by cryptographic public keys assigned to the respective entities. Subsequent data sent to the smart contract may include a message signed by private keys corresponding to the public keys identifying the subrogation claimant and defendant in the smart contract, thus providing cryptographic proof that the transaction was originated by one of the parties to the dispute. The private and public keys may be managed solely by the parties to minimize the attack surface for any attackers that might attempt to forge a transaction (e.g., the parties generate public/private cryptographic key pairs offline and only provide the public key to other network participants). A party&#39;s private keys may be generated according to a securely stored seed value (e.g., on a piece of physical paper or multiple copies of a piece of paper) such that the private keys may be recovered in the case of a data loss. 
     The smart contract state  506  may further include information regarding the basis of the subrogation claim, such as the policy holder and a description of the damages suffered (e.g., date, time, place, etc.). A subrogation blockchain network participant may monitor the blockchain  502  for any subrogation claims that identify the participant as a subrogation defendant. As such, it is not necessary for a subrogation claimant to notify a subrogation defendant “off-chain” of the existence of the claim. A subrogation claimant may additionally make such a notification to the subrogation defendant as a redundant communication. 
     Resolving a subrogation claim may require assembling evidence of the damages suffered by a policy holder. The evidence may take the form of expert or witness statements (e.g., a statement from a treating doctor that an injury and/or medical care was the result of a collision, statement of a witness to a collision tending to establish the fault of the subrogation defendant&#39;s insured vehicle driver, etc.). The evidence may also take the form of documentary evidence (e.g., report from an authorized automotive repair services provider of damage to a vehicle as the result of a collision, a repair estimate, a repair bill for repair services rendered, a certification from a government entity that a vehicle involved in a collision had a valid registration, etc.). Similarly, evidence may be supplied by oracles, such as by the oracles  148  discussed in  FIG.  1   . 
     As evidence regarding the subrogation claim may be collected from the various entities involved (medical, auto repair, governmental, etc.), these entities may broadcast transactions to the blockchain  502  to reflect the status of the loss and to provide the evidence therefor to other network participants, specifically the subrogation claimant and defendant. For example, a doctor who treated a patient for injuries sustained in a collision may broadcast a transaction sending data to the smart contract to connect the patient&#39;s injuries to the collision. The evidence may take the form of a cryptographically signed statement from the doctor attesting to the injuries. The evidence may take the form of a digitized X-ray or other medical record tending to prove the existence of an injury. The evidence may further take the form of medical bills issued by the hospital for services rendered for the injuries. 
     Like the subrogation claimant and defendant, a doctor or hospital may own a private cryptographic key that corresponds to a public cryptographic key known to belong to the hospital or doctor by the other network participants. By signing any submitted evidence with the private cryptographic key, the hospital or doctor may provide cryptographic proof of identity to the subrogation defendant that the evidence was truly submitted by the doctor or hospital. A subrogation defendant may choose to rely solely on the cryptographic proof offered by the doctor/hospital without separately contacting the doctor/hospital to verify the data. In this way, the blockchain  502  may reduce time and cost associated with resolving a subrogation claim. 
     The subrogation defendant may also submit comments in response to the evidence by broadcasting transactions to the blockchain  502 . Additionally, the subrogation claimant may submit comments in response to the subrogation defendant&#39;s comments by broadcasting transactions to the blockchain  502 , and the subrogation defendant and claimant may have a discussion back and forth that is broadcasted to the blockchain  502 . The comments that form the discussion back and forth may be stored as part of the smart contract state data for recordkeeping purposes. 
     Another aspect of the subrogation smart contract state  506  associated with a subrogation claim may be the smart contract data. Smart contract data may be thought of like the private and public data in an object created according to an object-oriented programming paradigm in that they may be directly updated from outside the object, or they may be updated only in limited ways, such as by calling a method of the smart contract. In at least one implementation, smart contract data may include an indication (e.g., a flag) as to whether the parties to the subrogation claim accept evidence in the smart contract as representative of the damages owed by the subrogation defendant. These flags may be set according to methods in the smart contract that may require the caller to prove its identity. The method may only permit, for example, a subrogation defendant to set a flag indicating the subrogation defendant&#39;s acceptance of a component of the damages of the subrogation claim. For example, once sufficient evidence relating to the cost of a medical treatment has been included in the smart contract, a subrogation claimant may indicate its approval of the evidence by setting a flag. 
     A subrogation defendant, upon review of the medical evidence, may choose to either set its corresponding flag to indicate its acceptance of the medical evidence, or it may decline to do so if it disputes the veracity of the evidence. As such, the smart contract state may track the various components of the damages owed and may refine points of dispute for the parties to the subrogation claim. When all sources of evidence for the value of the subrogation claim have been approved by the subrogation claimant and defendant, the value of the claim may have been determined and agreed upon, and a subrogation defendant may mark the settlement as agreed by sending data to the smart contract. Additionally, the subrogation defendant may mark the settlement as paid. In at least one implementation, the blockchain  502  may include a circulating token having value with which the subrogation defendant may pay the subrogation claimant. 
     The smart contract data may also include an indication (e.g., a flag) as to whether each of the parties to the subrogation claim have provided an offer or a counter-offer, and the corresponding amount of the offer or counter-offer. These flags may be set according to methods in the smart contract that may require the caller to prove its identity. The method may only permit, for example, the opposing party to set a flag indicating the opposing party&#39;s counter-offer and the amount of the counter-offer. For example, when the subrogation defendant submits an offer, only the subrogation claimant may set a flag indicating a counter-offer and the amount of the counter-offer. The offers and counter-offers that represent the negotiation back and forth may be stored as part of the smart contract state data for recordkeeping purposes. 
       FIG.  5    depicts an exemplary blockchain system  500  in accordance with one aspect of the present disclosure.  FIG.  5    includes a blockchain  502 , a block of transactions  504 , a Merkle Tree  506 , and a transaction  508 . The Merkle Tree may be the above-referenced Merkle Tree that cryptographically links transactions together. In other embodiments, the blockchain system  500  may utilize a different method of organizing transactions in a block. In some embodiments, the blockchain system  500  may include a plurality of blocks connected together to form a chain of blocks of transactions  502 . 
     In some implementation, the block of transactions  504  may organize the transactions it has received into a Merkle Tree to facilitate access to the stored transactions. The transactions may be hashed using a cryptographic hash algorithm, such as the algorithms discussed above, and the hash of each transaction may be stored in the tree. As the tree is constructed, the hash of each adjacent node at the same level may be hashed together to create a new node that exists at a higher level in the tree. Therefore, the root of the tree, or the node at the top of the tree, may be dependent upon the hash of each transaction stored below in the tree. Each transaction may include a set of data. The set of data may include identifying data for the transaction, and transaction data identifying the nature of the transaction and what the transaction entails (e.g., input and output addresses, a transaction value, a document hash value, a timestamp, a transaction fee value, etc.). 
     In one implementation, documents stored “on” a blockchain may be documents that have been hashed according to a cryptographic hashing algorithm (e.g., SHA-256), and the resulting output hash may be included in a transaction in a block that has been accepted by the network nodes as satisfying the consensus rules of the blockchain. As such, the documents may be later verified or validated by comparing the hash of the documents to the hash stored on the blockchain. For example, if a set of documents results in a SHA-256 hash that was recorded on a blockchain on a certain date, then the blockchain may provide cryptographic proof that the documents existed as of that date. 
     One way of storing a document on a blockchain may be to broadcast a transaction including a hash of the document to the network, which may be included in a block if the transaction satisfies all of the consensus rules of the network. In some implementations, the blockchain may be a permissioned ledger, meaning only authorized network participants may broadcast transactions. In other implementations, only some authorized network participants may make certain transactions. For example, vehicle telematics data tending to show which vehicle was at fault in a collision may be uploaded by the vehicle to the blockchain  502  contemporaneously with, or subsequent to, a collision. Only a cryptographic hash of the data may be included in the blockchain  502  such that the data may be verified using the blockchain even if it is obtained by a party off-chain. 
     Validating network nodes may verify that the signed transaction or signed message was signed by the private cryptographic key corresponding to the published public cryptographic key owned by the authorized vehicle manufacturer. In at least one implementation, a valid proof-of-identity may be applied as a consensus rule by the blockchain network. As such, any transaction attempting to add a new VIN number to the blockchain without a cryptographic proof-of-identity matching an identity authorized to add a new VIN number may be rejected by the network as non-compliant with the consensus rule. 
       FIG.  6    depicts an exemplary transaction  600  representing an evidence transaction generated by an evidence oracle associated with one aspect of the present disclosure. The evidence oracle may collect data on a traffic intersection  612 . This intersection may be of interest to insurers if it has a history for being a dangerous intersection where collisions frequently occur. The data may be packaged into a transaction, such as transaction  606 . The evidence oracle may broadcast transaction  606  to distributed ledger  602  to be included in a block, such as block  604 . The transaction  606  may include data such as a transaction ID, an originator (identified by a cryptographic proof-of-identity, and/or a unique oracle ID), an evidence type, such as video and audio evidence, and a cryptographic hash of the evidence. In another implementation, the evidence may not be stored as a cryptographic hash, but may be directly accessible in block  604  by an observer or other network participant, such as the participants in a subrogation claim. 
     Evidence Oracles 
       FIG.  7    depicts an exemplary flow diagram  700  associated with one aspect of the present disclosure, and in particular, providing data relevant to accidents and subrogation claims by interacting with a distributed ledger. The computer-implemented method depicted in  FIG.  7    is one exemplary implementation, whereas alternative methods and systems are discussed below. In some embodiments, the network of participants may be the nodes described above, for example node  400  depicted in  FIG.  4   . The blockchain used by the participants may be the blockchain  200  depicted in  FIG.  2   , whose operation is described above. The steps of the computer-implemented method  700  may be performed by the nodes in the network of participants, such as the nodes described in  FIGS.  1 - 4   . In addition, the method may interact with smart contracts stored in the distributed ledger, such as the exemplary smart contract depicted in  FIG.  5   . The method  700  may include additional, fewer, or alternative actions, including those described elsewhere herein. 
     In one embodiment, a computer-implemented method for providing data relevant to accidents and subrogation claims by interacting with a distributed ledger may be provided. The method may be executed by an oracle, such as the evidence oracles discussed with respect to  FIGS.  1  and  6   . The method may include (1) receiving (such as via wireless communication or data transmission over one or more radio links or communication channels), at one or more processors (and/or associated transceivers), recorded data from one or more connected devices at a geographic location (block  702 ); (2) analyzing, at the one or more processors, the recorded data, wherein analyzing the recorded data may include determining that an accident has occurred involving one or more vehicles (block  704 ); (3) generating, at the one or more processors, a transaction including the data indicative of the accident based upon the analysis (block  706 ); and/or (4) transmitting (such as via wireless communication or data transmission over one or more radio links or communication channels), at the one or more processors (and/or associated transceivers), the transaction to at least one other participant in the distributed ledger network (block  708 ). 
     In some embodiments, the recorded data may be sensor data, audio data, video data, image data, vehicle or home telematics data, smart vehicle data, autonomous or semi-autonomous vehicle data, smart or interconnected data, and combinations thereof. The recorded data may be data that is input into the distributed ledger by oracles, such as by the oracles discussed with respect to  FIGS.  1  and  6   . The data may be recorded data that is recorded in real-time by the oracle as events occur. Real-time data may be data that is representative of events as they happen in “real-time,” that is where the interval between data collection periods is exceedingly small, such as by the second, or by the microsecond. Alternatively, for some data types, data collected every few seconds or minutes may be considered real-time data. This data may be packaged into transactions that are broadcast to the distributed ledger on a periodic basis, such as, for example, by the second, minute, hour, day, week, or month. 
     In some embodiments, the geographic location may be a traffic intersection, a road segment, a waterway, a bridge, or combinations thereof. The geographic location may be a location that is known by an insurance provider to be a dangerous location where accidents are known to occur. 
     In some embodiments, determining an accident has occurred may include comparing, at the one or more processors, the recorded data to a baseline data profile for a type of recorded data related to the received recorded data. The baseline data profile may depict what “normal” conditions are at the geographic location when no accidents are occurring. For example, a picture of street with no cars on it may be a normal condition. Alternatively, a picture of two cars that crashed into each other may be an accident condition. The baseline profile may be built by analyzing historical data for the geographic location, as well as historical claims data provided by an insurance provider. 
     In some embodiments, generating the transaction, may include identifying, at the one or more processors, identity data for the one or more connected devices; augmenting, at the one or more processors, the transaction with the identity data for the one or more connected devices; generating, at the one or more processors, a cryptographic signature based upon the transaction; and/or augmenting, at the one or more processors, the transaction with the cryptographic signature. The identity data may be an identification number assigned to a connected device at the device&#39;s creation, and/or an identity number assigned to the device when it joined the distributed ledger network. In some embodiments, the identity data may be data for the vehicles involved in the accident, such as an identifier for a vehicle created at the vehicle&#39;s creation, a number provided by an insurance provider for the vehicle, an insurance policy number, or combinations thereof. 
     Some embodiments of the method may include, adding, at the one or more processors, the transaction to a block of transactions; solving, at the one or more processors, a cryptographic puzzle based upon the block of transactions; adding, at the one or more processors, the solution to the cryptographic puzzle to the block of transactions; and/or transmitting, at the one or more processors, the block of transactions to at least one other participant in the distributed ledger network. Similarly, in other embodiments a proof of stake algorithm, such as the one discussed above with respect to  FIG.  3   , may be used when constructing a block of transactions. 
     In some embodiments of the method, an accident has not occurred, or it is unclear if an accident has occurred from the evidence available. In this situation, the method may include updating, at the one or more processors, a database with the recorded data. 
     An alternative embodiment of the method may include receiving (such as via wireless communication or data transmission over one or more radio links or communication channels), at one or more processors and/or associated transceivers, a request for recorded data from at least one other participant in the distributed ledger network; verifying, at the one or more processors, an access level for the at least one other participant; analyzing, at the one or more processors, the request for recorded data, wherein analyzing may include determining data relevant to the request; generating, at the one or more processors, a transaction including the data relevant to the request; and/or transmitting, at the one or more processors and/or associated transceivers, the transaction to the at least one other participant in the distributed ledger network. 
     In certain embodiments of the aforementioned method, the request for recorded data may be triggered by a transaction on the distributed ledger network related to a subrogation claim. For example, a participant in the network may monitor the network for transactions related to a subrogation claim, and subsequently request relevant evidence data from any evidence nodes on the network. 
     In some embodiments of the method, verifying the access level for the at least one participant requesting the recorded data may further include determining, at the one or more processors, an identity for the at least one other participant; and/or checking, at the one or more processors, the identity against a database of access levels listing who may access the recorded data. Not all participants in the distributed ledger network may have the necessary authority, legally or otherwise, to view all other participants and data transacted on the network. In this manner, the distributed ledger network may be a permissioned network. The nodes may have varying levels of authority allowing them to see particular data they have the right to access. These rights may be tracked as part of a “white list,” or “access list,” that records whom has access to what information. This list may be cross-referenced as part of the verification process. 
     In some embodiments, analyzing the request for recorded data may further include determining, at the one or more processors, a type of data requested; and/or determining, at the one or more processors, an amount of data requested. Oracles may submit different types of data, such as video, audio, environmental, etc., and the data type may need to be determined before answering a request. 
     In some embodiments, generating the transaction, may include identifying, at the one or more processors, identity data for one or more connected devices that recorded the recorded data; augmenting, at the one or more processors, the transaction with the identity data for the one or more connected devices; generating, at the one or more processors, a cryptographic signature based upon the transaction; and/or augmenting, at the one or more processors, the transaction with the cryptographic signature. Transactions may be secured using cryptographic hashes so that participants in the network may verify the provenance of the transaction. 
     The method may include adding, at the one or more processors, the transaction to a block of transactions; solving, at the one or more processors, a cryptographic puzzle based upon the block of transactions; adding, at the one or more processors, the solution to the cryptographic puzzle to the block of transactions; and/or transmitting, at the one or more processors and/or associated transceivers, the block of transactions to at least one other participant in the distributed ledger network. Similarly, in other embodiments, a proof of stake algorithm, such as the one discussed above with respect to  FIG.  3   , may be used when constructing a block of transactions. 
     In one alternative embodiment, a computer system for providing data relevant to accidents and subrogation claims by interacting with a distributed ledger may be provided. The system may include a network interface configured to interface with a processor; one or more sensors; a memory configured to store non-transitory computer executable instructions and configured to interface with the processor; and the processor may be configured to interface with the memory. The processor may be configured to execute the non-transitory computer executable instructions to cause the processor to: (1) receive recorded data from one or more connected devices at a geographic location; (2) analyze the recorded data, wherein analyzing the recorded data may include determining that an accident has occurred involving one or more vehicles; (3) generate a transaction including the data indicative of the accident based upon the analysis; and/or (4) transmit the transaction to at least one other participant in the distributed ledger network. 
     Recommended Subrogation Amounts 
       FIG.  8    depicts an exemplary flow diagram  800  associated with one aspect of the present disclosure, and in particular, generating suggested subrogation amounts using machine learning. The computer-implemented method depicted in  FIG.  8    is one exemplary implementation, whereas alternative methods and systems are discussed below. In some embodiments, the network of participants may be the nodes described above, for example node  400  depicted in  FIG.  4   . The blockchain used by the participants may be the blockchain  200  depicted in  FIG.  2   , whose operation is described above. The steps of the computer-implemented method  800  may be performed by the nodes in the network of participants, such as the nodes described in  FIGS.  1 - 4   . In addition, the method may interact with smart contracts stored in the distributed ledger, such as the exemplary smart contract depicted in  FIG.  5   . The method  800  may include additional, fewer, or alternative actions, including those described elsewhere herein. 
     Determining subrogation amounts may be a difficult and time consuming process. A software program that leverages machine learning may be able to monitor transactions on a distributed ledger and suggest subrogation amounts related to subrogation claims that are being processed. For example, a computer-implemented method for generating suggested subrogation amounts using machine learning, including using deep learning or reinforced learning techniques, may be provided. The method may include (1) monitoring, at one or more processors and/or associated transceivers, transactions on the distributed ledger (block  802 ); (2) identifying, at the one or more processors, a transaction related to a subrogation claim (block  804 ); (3) analyzing, at the one or more processors, the transaction related to the subrogation claim (block  806 ); (4) generating, at the one or more processors, a recommended subrogation resolution using a machine learning algorithm (block  808 ); and/or (5) transmitting, at the one or more processors and/or associated transceivers, a transaction including the recommended subrogation resolution to a smart contract stored on the distributed ledger (block  810 ). 
     In some embodiments, monitoring transactions on the distributed ledger may further include monitoring, at the one or more processors and/or associated transceivers, a smart contract stored at an address on the distributed ledger. The smart contract may be a subrogation smart contract with a state, such as the smart contract state  506  depicted in  FIG.  5   . 
     In some embodiments, identifying a transaction related to a subrogation claim may further include identifying, at the one or more processors, a subrogation ID in a transaction; and/or validating, at the one or more processors, the subrogation ID. The subrogation ID may be for the claimant, a defendant, or even for the address where a smart contract is located. 
     In some embodiments, analyzing the transaction related to the subrogation claim may further include analyzing, at the one or more processors, damages data contained in the transaction; and/or analyzing, at the one or more processors, services rendered data contained in the transaction. The damages data may be collected by oracles, such as the oracles depicted in  FIGS.  1  and  6   . The services rendered data may be derived from transactions on the distributed ledger, or retrieved from addresses on the distributed ledger. 
     In some embodiments, generating a recommended subrogation resolution using a machine learning algorithm, may further include executing, at the one or more processors, a machine learning algorithm on damages data and services rendered data included in the transaction. The machine learning algorithm may be trained on historical insurance claims data. This data may be used to help the algorithm “learn” optimal amounts for subrogation claims based upon past filings. The machine learning algorithm may be a supervised learning algorithm, employ decision trees, make use of an artificial neural network, make use of Bayesian statistical analysis, deep learning and/or reinforced or reinforcement learning algorithm, or combinations thereof. 
     In some embodiments, the machine learning algorithm may include comparing, at the one or more processors, the damages data and services rendered data to a historical dataset for damages data and services rendered data; and/or identifying, at the one or more processors, similarities and differences between the datasets. 
     In some embodiments, generating a recommended subrogation resolution using a machine learning algorithm, may further include determining, at the one or more processors, a subrogation amount for an at-fault insurer, and a not-at-fault insurer. 
     Some embodiments of the method include adding, at the one or more processors, the transaction to a block of transactions; solving, at the one or more processors, a cryptographic puzzle based upon the block of transactions; adding, at the one or more processors, the solution to the cryptographic puzzle to the block of transactions; and/or transmitting, at the one or more processors, the block of transactions to at least one other participant in the distributed ledger network. Similarly, in other embodiments a proof of stake algorithm, such as the one discussed above with respect to  FIG.  3   , may be used when constructing a block of transactions. 
     An alternative embodiment of the method may include (1) receiving (such as via wireless communication or data transmission over one or more radio links or communication channels), at the one or more processors and/or associated transceivers, a transaction related to a subrogation claim; (2) analyzing, at the one or more processors, the transaction related to the subrogation claim; (3) generating, at the one or more processors, a recommended subrogation resolution based upon the analysis of the transaction; and/or (4) transmitting, at the one or more processors, a transaction including the recommended subrogation resolution to a smart contract stored on the distributed ledger. 
     Yet another alternative embodiment may be a computer system for interacting with a distributed ledger. The system may include a network interface configured to interface with a processor; and a memory configured to store non-transitory computer executable instructions and configured to interface with the processor. The processor may be configured to interface with the memory, wherein the processor may be configured to execute the non-transitory computer executable instructions to cause the processor to: (1) monitor transactions on the distributed ledger; (2) identify a transaction related to a subrogation claim; (3) analyze the transaction related to the subrogation claim; (4) generate a recommended subrogation resolution using a machine learning algorithm; and/or (5) transmit a transaction including the recommended subrogation resolution to a smart contract stored on the distributed ledger. 
     Line Item Dispute Determination 
       FIG.  9    depicts an exemplary flow diagram  800  associated with one aspect of the present disclosure, and in particular, for providing a line item dispute mechanism related to a subrogation claim. The computer-implemented method depicted in  FIG.  9    is one exemplary implementation, whereas alternative methods and systems are discussed below. In some embodiments, the network of participants may be the nodes described above, for example node  400  depicted in  FIG.  4   . The blockchain used by the participants may be the blockchain  200  depicted in  FIG.  2   , whose operation is described above. The steps of the computer-implemented method  800  may be performed by the nodes in the network of participants, such as the nodes described in  FIGS.  1 - 4   . In addition, the method may interact with smart contracts stored in the distributed ledger, such as the example smart contract depicted in  FIG.  5   . The method  800  may include additional, fewer, or alternative actions, including those described elsewhere herein. 
     Line item disputes may be common in the insurance claim process, and in particular, the subrogation claim process. Line items may be entries on a bill for services rendered related to repairs performed as a result of a collision, healthcare received as a result of a collision, or combinations thereof. 
     An exemplary computer-implemented method for providing a line item dispute mechanism related to a subrogation claim may be provided. The method may include (1) receiving (such as via wireless communication or data transmission over one or more radio links or communication channels), at one or more processors and/or associated transceivers, a transaction from at least one other participant in the distributed ledger network (block  902 ); (2) analyzing, at the one or more processors, the transaction to determine a set of line items related to a subrogation claim (block  904 ); (3) comparing, at the one or more processors, the set of line items to a baseline dataset (block  906 ); (4) generating, at the one or more processors, a transaction including a disputed line items dataset (block  908 ); and/or (5) transmitting, at the one or more processors and/or associated transceivers, the transaction to a smart contract stored on the distributed ledger (block  910 ). 
     In some embodiments, the transaction may include a transaction ID, a subrogation contract ID, an originator, a damages dataset, and/or a services rendered dataset. Additional information may be included on the vehicles involved in the collision (including smart or autonomous vehicles), insurance providers for the vehicles, as well as any other service providers relevant to the collision. Similarly, information on the drivers of the vehicles may also be included. 
     In some embodiments of the method, receiving (such as via wireless communication or data transmission over one or more radio links or communication channels) the transaction, may further include verifying, at the one or more processors, an identifier for the at least one other participant. The identifier may be assigned to the participant when they join the distributed ledger network, may be an address where the participant holds funds on the network, and/or may be an identifier generated off the network by an issuing authority, such as a government agency, or private business. 
     In some embodiments, analyzing the transaction may further include determining, at the one or more processors, damages data and services rendered data included in the transaction. Determining this data may include identifying the type of data included in the transaction, as well as the amount of data included in the transaction. 
     In some embodiments, the baseline dataset is a dataset containing suggested ranges for damages amounts and costs for services rendered. These suggested ranges may be maintained by a participant in the distributed ledger network, such as an insurance provider or arbitrator. The suggested ranges may also be determined dynamically by analyzing historical claims data. 
     In some embodiments, comparing the set of line items to a baseline dataset may further include identifying, at the one or more processors, differences between amounts for the set of line items and amounts for the baseline dataset. The difference may be an amount overpaid, as determined by the counter party, or by a party in the subrogation process as determined by the party subject to the subrogation. 
     In some embodiments of the method, generating the transaction including the disputed line items dataset, may further include generating, at the one or more processors, the disputed line items dataset based upon the comparison of the set of line items to the baseline set. 
     Some embodiments of the method may include (1) receiving (such as via wireless communication or data transmission over one or more radio links or communication channels), at the one or more processors and/or associated transceivers, a response transaction related to the disputed line items; (2) analyzing, at the one or more processors, the response transaction; and/or (3) transmitting, at the one or more processors and/or associated transceivers, an updated disputed line items transaction to at least one other participant. The response transaction may be the result of the counterparty to the subrogation objecting to a disputed line item, providing evidence of the veracity of the disputed line item, or combinations thereof. Based upon this disputed line items, and the response, an updated line item transaction may be communicated to participants in the network. Eventually, after a number of transactions, there may be no more line items that are under dispute. 
     Another embodiment may involve a computer system for providing a line item dispute mechanism related to a subrogation claim. The system may include a network interface configured to interface with a processor; a memory configured to store non-transitory computer executable instructions and configured to interface with the processor; and the processor may be configured to interface with the memory. The processor may be configured to execute the non-transitory computer executable instructions to cause the processor to: (1) receive a transaction from at least one other participant in the distributed ledger network; (2) analyze the transaction to determine a set of line items related to a subrogation claim; (3) compare the set of line items to a baseline dataset; (4) generate a transaction including a disputed line items dataset; and/or (5) transmit the transaction to a smart contract stored on the distributed ledger. 
     In one alternative embodiment, a computer-implemented method for interacting with a distributed ledger maintained by a plurality of participants may be provided. The method may include (1) receiving, at one or more processors and/or associated transceivers, a disputed line item transaction from at least one other participant in the distributed ledger network; (2) analyzing, at the one or more processors, the disputed line item transaction; (3) generating, at the one or more processors, a confirmation transaction including a consent dataset related to the disputed line item or items (block  906 ); and/or (4) transmitting, at the one or more processors and/or associated transceivers, the confirmation transaction to a smart contract stored on the distributed ledger. 
     In some embodiments, the disputed line item transaction may include a transaction ID, a subrogation contract ID, an originator, a damages dataset, and/or a services rendered dataset. In other embodiments, analyzing the disputed line item transaction, further may include determining, at the one or more processors, damages data and services rendered data included in the disputed line item transaction. 
     In some embodiments, generating the confirmation transaction including the consent dataset related to the disputed line items, further may include generating, at the one or more processors, the consent dataset based upon the comparison of the damages data and services rendered data included in the disputed line item transaction to an acceptable consent dataset. 
     One alternative embodiment of the method may include (1) receiving (such as via wireless communication or data transmission over one or more radio links or communication channels), at one or more processors and/or associated transceivers, a disputed line item transaction from at least one other participant in the distributed ledger network; (2) analyzing, at the one or more processors, the disputed line item transaction; (3) generating, at the one or more processors, a confirmation transaction including a consent dataset related to the disputed line item or items; and/or (4) transmitting (such as via wireless communication or data transmission over one or more radio links or communication channels), at the one or more processors and/or associated transceivers, the transaction to a smart contract stored on the distributed ledger. The confirmation transaction may be used by other parties involved in the subrogation process to verify agreement on line items between the parties involved. 
     Vehicle Subrogation Claim Creation 
       FIG.  10    depicts an exemplary flow diagram  1000  associated with one aspect of the present disclosure, and in particular, interacting with a distributed ledger to create subrogation claims related to a vehicle accident. The computer-implemented method depicted in  FIG.  10    is one exemplary implementation, whereas alternative methods and systems are discussed below. In some embodiments, the network of participants may be the nodes described above, for example node  400  depicted in  FIG.  4   . The blockchain used by the participants may be the blockchain  200  depicted in  FIG.  2   , whose operation is described above. The steps of the computer-implemented method  1000  may be performed by the nodes in the network of participants, such as the nodes described in  FIGS.  1 - 4   . In addition, the method may interact with smart contracts stored in the distributed ledger, such as the exemplary smart contract depicted in  FIG.  5   . The method  1000  may include additional, fewer, or alternative actions, including those described elsewhere herein. 
     Vehicles today may have a plurality of computers contained within them. These computers monitor the status of the vehicle, as well as travel information pertaining to the vehicle. Accordingly, when a vehicle is involved in an accident, the computers in the vehicle may collect data related to the accident, as well as have data that may be relevant prior to when the accident occurred (such as telematics data (such as speed, location, GPS, cornering, braking, acceleration, and other types of vehicle telematics data); image data; sensor data; audio data; autonomous or semi-autonomous vehicle system control decision, operational, or other data; etc.). This data may be collected from the parts or sensors of the vehicle. In some cases, due to the nature of the data it may be obvious that the vehicle driver is not at fault. For example, if the vehicle is hit in the rear, the vehicle driver may likely not be solely liable for any damages to the vehicle. As such, it may be more efficient for the vehicle itself to create a subrogation claim based off the data and transmit that claim as a transaction on a distributed ledger. If no distributed ledger exists, or the vehicle is not connected to one, the vehicle may create a distributed ledger, or join a distributed ledger. 
     An exemplary computer-implemented method for interacting with a distributed ledger maintained by a plurality of participants may be provided. The method may include (1) receiving (such as via wireless communication or data transmission over one or more radio links or communication channels), at one or more processors and/or associated transceivers, sensor data indicative of a vehicle accident (block  1002 ); (2) analyzing, at the one or more processors, a set of components to assess potential damage (block  1004 ); (3) generating, at the one or more processors, a damages dataset based upon the analysis (block  1006 ); (4) generating, at the one or more processors, a transaction including an identifier for a vehicle involved in the vehicle accident and the damages dataset (block  1008 ); and/or (5) transmitting, at the one or more processors and/or transceivers, the transaction to at least one other participant (block  1010 ). 
     In some embodiments, the sensor data may be received from the vehicle (which may be a smart, autonomous, or semi-autonomous vehicle) involved in the vehicle accident. The sensor data may include image, telematics, audio, and/or other sensor data. For instance, the sensor data may include operational data or control decision data associated with one or more autonomous or semi-autonomous vehicle systems or features. Additionally or alternatively, the sensor data may be telematics or vehicle data indicative of braking, cornering, location, acceleration, direction, GPS location or speed, speed, position, orientation, location, impact, or combinations thereof. If the vehicle is capable of vehicle-to-vehicle communication (V2V), the vehicle data may conform to certain standards, such as the SAE J2735 Dedicated Short Range Communications Message Set. In some cases, the vehicle data may be retrieved from a cloud storage solution that receives vehicle data uploads for the vehicle as the vehicle is under operation. 
     In some embodiments, analyzing the set of components may further include collecting, at the one or more processors, accident data from the set of components. The set of components of the vehicle may include the engine, the brakes, the tires, the air bags, the steering wheel, the suspension system, the windows and windshields, the front and/or rear bumpers, the exhaust, the ignition, any telecommunications system the vehicle may have, as well as any other parts and/or smart parts or smart components that comprise the vehicle. 
     In some embodiments of the method, analyzing the set of components may further include (1) determining, at the one or more processors, a subrogation claim related to the vehicle accident; (2) generating, at the one or more processors, a smart contract related to the subrogation claim; and/or (3) deploying, at the one or more processors, the smart contract to the distributed ledger. Determining the subrogation claim may include analyzing the damage level done to any components in the set of components that were damaged in the accident. This information may evidence, such as in the case of a “fender bender” where the vehicle is struck from the rear, that the vehicle driver is not, or may not be, entirely at fault. As such, the smart contract may include this information when determining the subrogation claim. The smart contract may be deployed as part of a transaction broadcast to the distributed ledger participants. 
     In some embodiments, generating the damages dataset may further include determining, at the one or more processors, a component status for each member of the set of components. As discussed above, the component status may be data indicative of the components damage caused by the accident. 
     In some cases, the damages dataset may include an insurance provider for the vehicle involved in the vehicle accident. The insurance provider information may already be stored on the distributed ledger in a transaction related to the vehicle, or in other cases, the vehicle itself may store information on the insurance provider that insures the vehicle. Similarly, information on the drivers that operate the vehicle may also be included in damages datasets. 
     In some embodiments, generating the transaction may further include (1) augmenting, at the one or more processors, the transaction with identity data for the vehicle; (2) generating, at the one or more processors, a cryptographic signature based upon the transaction; and/or (3) augmenting, at the one or more processors, the transaction with the cryptographic signature. Transactions may be secured using cryptographic hashes so that participants in the network may verify the provenance of the transaction. 
     In some embodiments, transmitting the transaction to at least one other participant, may further include transmitting, at the one or more processors and/or associated transceivers, the transaction to a smart contract stored on the distributed ledger. This smart contract may be owned by an insurance provider for the vehicle, or may be owned by the vehicle, or owned by the vehicle&#39;s owner. 
     In one alternative embodiment, a computer-implemented method for interacting with a distributed ledger maintained by a plurality of participants may be provided. The method may include (1) receiving (such as via wireless communication or data transmission over one or more radio links or communication channels), at one or more processors and/or associated transceivers, sensor data indicative of a vehicle accident (the sensor data may include image data; audio data; autonomous or semi-autonomous system or feature data (such as autonomous system operational or control decision data); telematics data; and/or other vehicle or mobile device sensor data); (2) analyzing, at the one or more processors, a set of components, which may include smart or other components, for a vehicle involved in the vehicle accident to assess potential damage; (3) generating, at the one or more processors, a damages dataset based upon the analysis; (4) creating, at the one or more processors, a distributed ledger for the vehicle involved in the vehicle accident; (5) deploying, at the one or more processors, a smart contract including the damages dataset and an identifier for the vehicle involved in the vehicle accident on the distributed ledger; (6) generating, at the one or more processors, a transaction including the identifier for a vehicle involved in the vehicle accident and the damages dataset; and/or (7) transmitting, at the one or more processors and/or associated transceivers, the transaction to at least one other participant in the distributed ledger. 
     In another embodiment, a computer system for interacting with a distributed ledger may be provided. The system may include: a network interface configured to interface with a processor; a memory configured to store non-transitory computer executable instructions and configured to interface with the processor (and/or an associated transceiver); and the processor may be configured to interface with the memory. The processor may be configured to execute the non-transitory computer executable instructions to cause the processor to: (1) receive sensor data (including image or autonomous system data, or other types of sensor data discussed elsewhere herein) indicative of a vehicle accident; (2) analyze a set of components, which may include smart or other components, to assess potential damage; (3) generate a damages dataset based upon the analysis; (4) generate a transaction including an identifier for a vehicle involved in the vehicle accident and the damages dataset; and/or (5) transmit the transaction to at least one other participant. 
     Exemplary Data Sources 
       FIG.  11    depicts exemplary data sources providing data to server configured to create blockchains or new blocks of data for insurance claim blockchains  1100 . A server  1102 , such as an insurance provider remote server, may collect data, with customer permission or affirmative consent, from customer mobile devices  1104 , smart vehicles  1106 , autonomous or semi-autonomous vehicles  1108 , vehicles of 3 rd  parties  1110  (such as surrounding vehicles that may or may not have been involved in a vehicle collision), smart infrastructure  1112 , smart or interconnected homes  1114 , 3 rd  parties  1116  (such as police or police vehicles, government computers, medical providers, repair shops, etc.), wearable electronic devices, such as smart watches  1118 , and aerial data (such as from satellites  1120 , drones  1122  (including autonomous or semi-autonomous drones), or airplanes  1124  (including autonomous or semi-autonomous airplanes), and/or other computing devices or sensors. The data collected may also include image data, video data, audio or sound data, sensor data, vehicle telematics or usage data, home telematics or usage data, vehicle operational data, and/or other information, including that discussed elsewhere herein. 
     The data generated by, and/or collected from, vehicles and/or mobile devices may include vehicle telematics data, such as GPS location, speed, acceleration, deceleration, cornering, braking, heading, route, and other types of telematics data. The telematics data may be updated periodically during vehicle usage, such as every 0.001 or 0.005 seconds. 
     All of the computing devices shown in  FIG.  11    may be parties or associated with parties having access to communication network and/or an insurance claim-related blockchain. For instance, a smart or autonomous vehicle may sense via one or more vehicle-mounted processors or sensors that it has been involved in a vehicle collision. The vehicle controller may then gather or generate vehicle sensor data, image data, audio data, and/or telematics data, and create a new insurance claim-related blockchain or a new block to add to an existing blockchain (which may include links to and/or the sensor and/or telematics data itself), and transmit the block or blockchain, and/or the sensor, image, audio, and/or telematics data, to a remote server to start the insurance claim handling process and/or vehicle reconstruction/assignment of fault process. 
     Telematics data, as used herein, may include telematics data, and/or other types of data that have not been conventionally viewed as “telematics data.” The telematics data may be generated by, and/or collected or received from, various sources, including those shown in  FIG.  11   . For example, the data may include, indicate, and/or relate to vehicle (and/or mobile device) speed; acceleration; braking; deceleration; turning or cornering; time; GPS (Global Positioning System) or GPS-derived location, speed, acceleration, or braking information; vehicle and/or vehicle equipment operation; external conditions (e.g., road, weather, traffic, and/or construction conditions); other vehicles or drivers in the vicinity of an accident; vehicle-to-vehicle (V2V) communications; vehicle-to-infrastructure or infrastructure-to-vehicle communications; drone-to-vehicle or vehicle-to-drone communications; vehicle-to-home or home-to-vehicle communications; drone-to-home or drone-to-infrastructure, or vice versa, communications; other smart or interconnected device-to-device communications; and/or image and/or audio information of the vehicle and/or insured driver before, during, and/or after an accident. The data may include other types of data, including those discussed elsewhere herein. The data may be collected via wired or wireless communication. 
     The data may be generated by mobile devices (smart phones, cell phones, lap tops, tablets, phablets, PDAs (Personal Digital Assistants), computers, smart watches, pagers, hand-held mobile or portable computing devices, smart glasses, smart electronic devices, wearable devices, smart contact lenses, and/or other computing devices); smart vehicles; dash or vehicle mounted systems or original telematics devices; public transportation systems; smart street signs or traffic lights; smart infrastructure, roads, or highway systems (including smart intersections, exit ramps, and/or toll booths); smart or interconnected homes; smart trains, buses, or planes (including those equipped with Wi-Fi or hotspot functionality); smart train or bus stations; internet sites; aerial, drone, or satellite images; 3 rd  party systems or data; nodes, relays, and/or other devices capable of wireless RF (Radio Frequency) communications; and/or other devices or systems that capture image, audio, or other data and/or are configured for wired or wireless communication. 
     In some embodiments, the data collected may also derive from police or fire departments, hospitals, and/or emergency responder communications; police reports; municipality information; and/or other data collected from government agencies and officials. The data from different sources or feeds may be aggregated. 
     The data generated may be transmitted, via wired or wireless communication, to a remote server, such as a remote server and/or other processor(s) associated with an insurance provider. The remote server and/or associated processors may build a database of the telematics and/or other data, and/or otherwise store the data collected. 
     The remote server and/or associated processors may analyze the data collected, and then perform certain actions and/or issue tailored communications based upon the data, including the insurance-related actions or communications discussed elsewhere herein. The automatic gathering and collecting of data from several sources by the insurance provider, such as via wired or wireless communication, may lead to expedited insurance-related activity, including the automatic identification of insured events, and/or the automatic or semi-automatic processing or adjusting of insurance claims. 
     In one embodiment, telematics data may be collected by a mobile device (e.g., smart phone) application. A telematics application that collects telematics data may ask an insured for permission to collect and send data about driver behavior and/or vehicle usage (including autonomous vehicle usage) to a remote server associated with an insurance provider. In return, the insurance provider may provide incentives to the insured, such as lower premiums or rates, or discounts and rebates. The telematics application for the mobile device may be downloadable off of the internet, in one embodiment. 
     During use, the telematics application or mobile device may, when within Bluetooth communication range, establish a Bluetooth connection with the vehicle, a vehicle controller, vehicle-mounted sensors, and/or other electronic devices within the vehicle capable of data transmission via Bluetooth frequencies. The Bluetooth communication may allow telematics data generated or collected by the mobile device to be communicated to the vehicle controller or control system, or conversely allow telematics data generated or collected by the vehicle controller (and/or vehicle-mounted sensors) to be communication to the mobile device. After which, the vehicle or mobile device may wirelessly transmit the telematics data collected to a remote server, such as insurance provider remote server, for further analysis. 
     Cause of Accident and/or Fault Determination 
     The present embodiments may determine the cause of a vehicle accident from analyzing the telematics, image, sensor, audio, and/or other data collected. An accident may be determined to have been fully, primarily, or partially caused by a number of factors, such as weather conditions, road or traffic conditions, construction, human error, technology error, vehicle or vehicle equipment faulty operation, and/or other factors. 
     In one aspect, the present embodiments may determine who or what was at fault (either entirely or partially) of causing a vehicle collision or accident. Mobile devices, smart vehicles, equipment and/or sensors mounted on and/or within a vehicle (including autonomous or semi-autonomous vehicle systems), and/or roadside or infrastructure systems may detect certain indicia of fault (for either one or more drivers, or one or more autonomous vehicles), or perhaps more importantly from the insured&#39;s perspective, a lack of fault. An insured may opt-in to an insurance program that allows an insurance provider to collect telematics, image, sensor, audio, and/or other data, and analyze that data for low risk driving and/or other behavior. The analysis of the data and/or low risk behavior identified may be applied and/or used to lower insurance premiums or rates for the insured or autonomous vehicle, and/or provide insurance discounts, rebates, or rewards to the insured or autonomous vehicle owner. 
     Telematics, sensor, audio, and image data and/or other types of data generated or collected by, for example, (i) a mobile device (smart phone, smart glasses, etc.), (ii) cameras mounted on the interior or exterior of an insured (or other) vehicle, (iii) sensors or cameras associated with a roadside system, and/or (iv) other electronic systems, such as those mentioned above, and/or may be time-stamped. The data may indicate that the driver was driving attentively before, during, and/or after an accident. For instance, the data collected may indicate that a driver was driving alone and/or not talking on a smart phone or texting before, during, and/or after an accident. Responsible or normal driving behavior may be detected and/or rewarded by an insurance provider, such as with lower rates or premiums, or with good driving discounts for the insured. 
     Additionally or alternatively, video or audio equipment or sensors may capture images or conversations illustrating that the driver was driving lawfully and/or was generally in good physical condition and calm before the accident. Such information may indicate that the other driver or motorist (for a two vehicle accident), or even vehicle in the case of an autonomous vehicle, may have been primarily at fault. 
     Conversely, an in-cabin camera or other device may capture images or video indicating that the driver (the insured) or another motorist (e.g., a driver uninsured by the insurance provider) involved in an accident was distracted or drowsy before, during, and/or after an accident. Likewise, erratic behavior or driving, and/or drug or alcohol use by the driver or another motorist, may be detected from various sources and sensors. Telematics data, such as data gathered from the vehicle and/or a mobile device, may also be used to determine that before or during an accident, one of the drivers was exhibiting good or proper driving behavior, or alternatively was speeding; following another vehicle too closely; and/or had time to react and avoid the accident. 
     In addition to human drivers, fault may be assigned to one or more autonomous or semi-autonomous vehicle systems or technologies. For instance, fault may be assigned vehicle collision avoidance functionality, such that the insured&#39;s insurance premium or rate may not be negatively impacted by faulty technology. The telematics, image, sensor, and/or other data collected may include video and/or audio data, and may indicate whether a vehicle, or certain vehicle equipment, operated as designed before, during, and/or after the accident. That data may assist in reconstructing a sequence of events associated with an insured event (e.g., a vehicle collision). 
     For instance, the data gathered may relate to whether or not the vehicle software or other collision avoidance functionality (or other autonomous features) operated as it was intended or otherwise designed to. Also, a smart vehicle control system or mobile device may use G-force data and/or acoustic information to determine certain events. The data may further indicate whether or not (1) an air bag deployed; (2) the vehicle brakes were engaged; and/or (3) vehicle safety equipment (lights, wipers, turn signals, etc.), and/or other vehicle systems operated properly, before, during, and/or after an accident. 
     Fault or blame, whole or partial, may further be assigned to environmental or other conditions. Weather, traffic, or road conditions; road construction; other accidents in the vicinity; and/or other conditions before, during, and/or after a vehicle accident (and in the vicinity of the location of the accident) may be determined (from analysis of the telematics, sensor, image, audio, and/or other data collected) to have contributed to causing the accident and/or insured event. A percentage of fault or blame may be assigned to each of the factors that contributed to causing an accident, and/or the severity thereof. 
     A sliding deductible and/or rate may depend upon the percentage of fault assigned to the insured or an insured autonomous or semi-autonomous vehicle. The percent of fault may be determined to be 0% or 100%, for example, which may impact an amount that is paid by the insurance provider for damages and/or an insurance claim. 
     Collision Reconstruction 
     The telematics, image, audio, sensor and/or other data gathered or collected from the various sources (such as mobile devices; smart vehicles; sensors or cameras mounted about a insured vehicle or a vehicle associated with another motorist; public transportation systems or other road side cameras; drone, aerial, or satellite images; etc.) may facilitate recreating the series of events that led to an accident or vehicle collision. The data gathered may be used by investigative services associated with an insurance provider to determine, for a vehicle accident, (1) an accident cause and/or (2) lack of fault and/or fault (or a percentage thereof) that is assigned or attributed to each of the drivers and/or vehicles (e.g., autonomous vehicles or autonomous or semi-autonomous vehicle systems) involved. The data gathered may also be used to identify a non-human cause of the accident, such as road construction, or weather, traffic, and/or road conditions, or faulty autonomous technologies. 
     A. Time-Stamped Sequence of Events 
     The series or sequence of events may facilitate establishing that an insured had no, or minimal, fault in causing the accident. Such information may lead to lower premiums or rates for the insured, and/or no change in insurance premiums or rates for the insured, or an insured vehicle, because of a vehicle accident for which the driver or vehicle was not at fault (and/or not primarily at fault). Proper fault determination, or a percentage thereof, may allow multiple insurance providers to assign proper risk to each driver or vehicle involved in an accident, and adjust their respective insurance premiums or rates accordingly such that good driving behavior or proper vehicle operation is not improperly penalized. 
     In one aspect, audio and/or video data may be recorded. Audio and video data may capture time-stamped sound and images, respectively. Sound and visual data may be associated with and/or indicate vehicle braking; vehicle speed; vehicle turning; turn signal, window wiper, head light, and/or brake light normal or faulty operation; windows breaking; air bags deploying; and/or whether the vehicle or vehicle equipment (including autonomous or semi-autonomous features) operated as designed for each vehicle involved in an insured event or vehicle accident. 
     B. Virtual Accident Reconstruction 
     The telematics, sensor, image, audio, and/or other data gathered may facilitate accident reconstruction, and an accident scene or series of events may be recreated. Noted above, from the series of events leading up to, during, and/or after the accident, fault (or a percentage of fault) may be assigned to an insured or another motorist, and/or one or more vehicles (such as autonomous vehicles). The data gathered may be viewed as accident forensic data, and/or may be applied to assign fault or blame to one or more drivers, one or more vehicles or vehicle systems, and/or one or more external conditions. 
     For example, the data gathered may indicate weather, traffic, road construction, and/or other conditions. The data gathered may facilitate scene reconstructions, such as graphic presentations on a display of a virtual map. The virtual map may include a location of an accident; areas of construction; areas of high or low traffic; and/or areas of bad weather (rain, ice, snow, etc.). 
     The virtual map may indicate a route taken by a vehicle or multiple vehicles involved in an accident. A timeline of events, and/or movement of one or more vehicles, may be depicted via, or superimposed upon, the virtual map. As a result, a graphical or virtual moving or animated representation of the events leading up to, during, and/or after the accident may be generated. 
     The virtual representation of the vehicle accident may facilitate (i) fault, or percentage of fault, assignment to one or more drivers, vehicles, or vehicle systems; and/or (ii) blame, or percentage of blame, assignment to one or more external conditions, such as weather, traffic, and/or construction. The assignments of fault or blame, or lack thereof, may be applied to handling various insurance claims associated with the vehicle accident, such as claims submitted by an insured or other motorists, or vehicle owner. The insured or vehicle owner may be insured by an insurance provider, and the other motorists may be insured by the same or another insurance provider. The assignments of fault or blame, or lack thereof, may lead to appropriate adjustments to the insurance premiums or rates for the insured and/or the other motorists, and/or insured vehicles, to reflect the cause or causes of the accident determined from the data collected. 
     The virtual representation of the vehicle accident may account for several vehicles involved in the accident. The sequence of events leading up to and including the accident may include analysis of the telematics, sensor, image, audio, and/or other data to determine or estimate what each of several vehicles and/or respective drivers did (or did not) do prior to, during, and/or after the accident. 
     As examples, voice data from using a smart phone to place a telephone call before or during an accident may indicate a distracted driver. Vehicle sensors may detect seat belt usage, such as seat belt usage before or during an accident, and/or the frequency or amount of seat belt usage by a specific driver. The data may reveal the number of children or other passengers in a vehicle before or during an accident. 
     Moreover, GPS (Global Positioning System) location and speed data from several vehicles may be collected. Other vehicle data may also be collected, such as data indicating whether (i) turn signals were used; (ii) head lights were on; (iii) the gas or brake pedal for a vehicle was pressed or depressed; and/or (iv) a vehicle was accelerating, decelerating, braking, maneuvering, turning, in their respective lane, and/or changing lanes. 
     Infrastructure data, such as image, audio, traffic, construction, weather, and/or other data from public transportation systems or smart traffic lights, may also be collected. Thus, for each vehicle accident or insured event a unique combination of data may be gathered at the insurance provider remote server and then analyzed to determine a most likely series of events leading up to the insured event. 
     Autonomous Automobile Functionality 
     As noted above, the present embodiments may relate to assessing and pricing insurance based upon autonomous (or semi-autonomous) functionality of a vehicle, and not the human driver. A smart or autonomous vehicle may maneuver itself without human intervention and/or include sensors, processors, computer instructions, and/or other components that may perform or direct certain actions conventionally performed by a human driver. 
     An analysis of how artificial intelligence facilitates avoiding accidents and/or mitigates the severity of accidents may be used to build a database and/or model of risk assessment. After which, automobile insurance risk and/or premiums (as well as insurance discounts, rewards, and/or points) may be adjusted based upon autonomous or semi-autonomous vehicle functionality, such as by groups of autonomous or semi-autonomous functionality or individual features. In one aspect, an evaluation may be performed of how artificial intelligence, and the usage thereof, impacts automobile accidents and/or automobile insurance claims. 
     The types of autonomous or semi-autonomous vehicle-related functionality or technology that may be used with the present embodiments to replace human driver actions may include and/or be related to the following types of functionality: (a) fully autonomous (driverless); (b) limited driver control; (c) vehicle-to-vehicle (V2V) wireless communication; (d) vehicle-to-infrastructure (and/or vice versa), and/or vehicle-to-device (such as mobile device or smart home controller) wireless communication; (e) automatic or semi-automatic steering; (f) automatic or semi-automatic acceleration; (g) automatic or semi-automatic braking; (h) automatic or semi-automatic blind spot monitoring; (i) automatic or semi-automatic collision warning; (j) adaptive cruise control; (k) automatic or semi-automatic parking/parking assistance; (1) automatic or semi-automatic collision preparation (windows roll up, seat adjusts upright, brakes pre-charge, etc.); (m) driver acuity/alertness monitoring; (n) pedestrian detection; (o) autonomous or semi-autonomous backup systems; (p) road mapping systems; (q) software security and anti-hacking measures; (r) theft prevention/automatic return; (s) automatic or semi-automatic driving without occupants; and/or other functionality. 
     In one embodiment, telematics and vehicle-mounted sensor data, and other data from the sources mentioned herein, may be generated and collected. From which, performance of various autonomous or semi-autonomous vehicle functionality or systems may be determined before, during, and/or after a vehicle collision. During accident reconstruction, assignment of a percentage of fault, or lack thereof, may be assigned to the autonomous or semi-autonomous functionality and systems mentioned herein in use, or supposed to be automatically engaged, during a vehicle collision. 
     Additionally or alternatively, the adjustments to automobile insurance rates or premiums based upon the autonomous or semi-autonomous vehicle-related functionality or technology may take into account the impact of such functionality or technology on the likelihood of a vehicle accident or collision occurring. For instance, a processor may analyze historical accident information and/or test data involving vehicles having autonomous or semi-autonomous functionality. Factors that may be analyzed and/or accounted for that are related to insurance risk, accident information, or test data may include (1) point of impact; (2) type of road; (3) time of day (TOD); (4) weather conditions; (5) road construction; (6) type/length of trip; (7) vehicle style; (8) level of pedestrian traffic; (9) level of vehicle congestion; (10) atypical situations (such as manual traffic signaling); (11) availability of internet connection for the vehicle; and/or other factors. These types of factors may also be weighted according to historical accident information, predicted accidents, vehicle trends, test data, and/or other considerations. 
     In one aspect, the benefit of one or more autonomous or semi-autonomous functionalities or capabilities may be determined, weighted, and/or otherwise characterized. For instance, the benefit of certain autonomous or semi-autonomous functionality may be substantially greater in city or congested traffic, as compared to open road or country driving traffic. Additionally or alternatively, certain autonomous or semi-autonomous functionality may only work effectively below a certain speed, i.e., during city driving or driving in congestion. Other autonomous or semi-autonomous functionality may operate more effectively on the highway and away from city traffic, such as cruise control. 
     Further, individual autonomous or semi-autonomous functionality may be impacted by weather, such as rain or snow, and/or time of day (day light versus night). As an example, fully automatic or semi-automatic lane detection warnings may be impacted by rain, snow, ice, and/or the amount of sunlight (all of which may impact the imaging or visibility of lane markings painted onto a road surface, and/or road markers or street signs). 
     Automobile insurance premiums, rates, discounts, rewards, refunds, points, etc. may be adjusted based upon the percentage of time or vehicle usage that the vehicle is the driver, i.e., the amount of time a specific driver uses each type of autonomous (or even semi-autonomous) vehicle functionality. In other words, insurance premiums (including usage-based insurance premiums or rates), discounts, rewards, etc. may be adjusted based upon the percentage of vehicle usage during which the autonomous or semi-autonomous functionality is in use. For example, automobile insurance risk, premiums, discounts, etc. for an automobile having one or more autonomous or semi-autonomous functionalities may be adjusted and/or set based upon the percentage of vehicle usage that the one or more individual autonomous or semi-autonomous vehicle functionalities are in use, anticipated to be used or employed by the driver, and/or otherwise operating. 
     Such usage information for a particular vehicle may be gathered over time and/or via remote wireless communication with the vehicle. One embodiment may involve a processor on the vehicle, such as within a vehicle control system or dashboard, monitoring in real-time whether vehicle autonomous or semi-autonomous functionality is currently operating. Other types of monitoring may be remotely performed, such as via wireless communication between the vehicle and a remote server or wireless communication between a vehicle-mounted dedicated device (that is configured to gather autonomous or semi-autonomous functionality usage information) and a remote server. 
     In one embodiment, if the vehicle is currently employing autonomous or semi-autonomous functionality, the vehicle may send a Vehicle-to-Vehicle (V2V) wireless communication to a nearby vehicle also employing the same or other type(s) of autonomous or semi-autonomous functionality. As an example, the V2V wireless communication from the first vehicle to the second vehicle (following the first vehicle) may indicate that the first vehicle is autonomously braking, and the degree to which the vehicle is automatically braking and/or slowing down. In response, the second vehicle may also automatically or autonomously brake as well, and the degree of automatically braking or slowing down of the second vehicle may be determined to match, or even exceed, that of the first vehicle. As a result, the second vehicle, traveling directly or indirectly, behind the first vehicle, may autonomously safely break in response to the first vehicle autonomously breaking. 
     As another example, the V2V wireless communication from the first vehicle to the second vehicle may indicate that the first vehicle is beginning or about to change lanes or turn. In response, the second vehicle may autonomously take appropriate action, such as automatically slow down, change lanes, turn, maneuver, etc. to avoid the first vehicle. 
     As noted above, the present embodiments may include remotely monitoring, in real-time and/or via wireless communication, vehicle autonomous or semi-autonomous functionality. From such remote monitoring, the present embodiments may remotely determine that a vehicle accident has occurred. As a result, emergency responders may be informed of the vehicle accident location via wireless communication, and/or quickly dispatched to the accident scene. 
     The present embodiments may also include remotely monitoring, in real-time or via wireless communication, that vehicle autonomous or semi-autonomous functionality is, or is not, in use, and/or collect information regarding the amount of usage of the autonomous or semi-autonomous functionality. Operational data and control decision data from autonomous or semi-autonomous systems may be collected, including data control decision data indicating what control decision were implemented or not implemented by various autonomous or semi-autonomous systems or features. From such remote monitoring, a remote server may remotely send a wireless communication to the vehicle to prompt the human driver to engage one or more specific vehicle autonomous or semi-autonomous functionalities. 
     Another embodiment may enable a vehicle to wirelessly communicate with a traffic light, railroad crossing, toll both, marker, sign, or other equipment along the side of a road or highway. As an example, a traffic light may wirelessly indicate to the vehicle that the traffic light is about to switch from green to yellow, or from yellow to red. In response to such an indication remotely received from the traffic light, the autonomous or semi-autonomous vehicle may automatically start to brake, and/or present or issue a warning/alert to the human driver. After which, the vehicle may wirelessly communicate with the vehicles traveling behind it that the traffic light is about to change, and/or that the vehicle has started to brake or slow down such that the following vehicles may also automatically brake or slow down accordingly. 
     Insurance premiums, rates, ratings, discounts, rewards, special offers, points, programs, claims, claim amounts, etc. may be adjusted for, or may otherwise take into account, the foregoing functionality and/or the other functionality described herein. For instance, insurance policies may be updated based upon autonomous or semi-autonomous vehicle functionality; V2V wireless communication-based autonomous or semi-autonomous vehicle functionality; and/or vehicle-to-infrastructure or infrastructure-to-vehicle wireless communication-based autonomous or semi-autonomous vehicle functionality.

The computer systems discussed herein may include or be implemented via computer-executable instructions stored on non-transitory computer-readable media or medium. 
     A processor or a processing element may be trained using supervised or unsupervised machine learning, and the machine learning program may employ a neural network, which may be a convolutional neural network, a deep learning neural network, deep learning algorithm or program, reinforced or reinforcement learning algorithm or program, or a combined learning module or program that learns in two or more fields or areas of interest. Machine learning may involve identifying and recognizing patterns in existing data in order to facilitate making predictions for subsequent data. Models may be created based upon example inputs in order to make valid and reliable predictions for novel inputs. 
     Additionally or alternatively, the machine learning programs may be trained by inputting sample data sets or certain data into the programs, such as drone, autonomous or semi-autonomous drone, image, mobile device, vehicle telematics, autonomous vehicle, smart vehicle, smart infrastructure, aerial or satellite, and/or intelligent home telematics data.

In unsupervised machine learning, the processing element may be required to find its own structure in unlabeled example inputs. 
     The telematics, sensor, image, audio, or other types of data discussed herein (such as historical data sets associated with a known vehicle collision and damage) may be collected and input into one or more machine learning programs to determine a vehicle collision occurred; determine a percentage of fault, of lack thereof, for a vehicle or vehicle system (autonomous vehicle or system) or vehicle driver; determine who or what system was in control of the vehicle during the collision (the vehicle, vehicle system, or vehicle driver); determine or estimate one or more line items for a subrogation demand or arbitration demand; determine or estimate vehicle damage or personal injuries resulting from the vehicle collision; and/or other functionality discussed herein based upon telematics, sensor, image, audio, and/or other data collected or received that is associated with a present or new vehicle collision.

     The foregoing computer systems may include additional, less, or alternate functionality, including that discussed elsewhere herein. 
     Additional Considerations 
     This detailed description is to be construed as exemplary only and does not describe every possible embodiment, as describing every possible embodiment would be impractical, if not impossible. One may be implement numerous alternate embodiments, using either current technology or technology developed after the filing date of this application. 
     An authoritative, trusted, immutable, distributed, shareable, secure system may be needed to record if a human driver is controlling a vehicle, and/or if the vehicle is acting autonomously or semi-autonomously. The record may include crash sensor data to record crash information correlating to driver control information. 
     Blockchain technology may be used to store the transactions of control instances (from autonomous to human control to autonomous, for example). These control instances may be stored as they occur into blocks. Accordingly, this data may be included into the distributed ledger environment of the blockchain. In this environment, a consensus system may fix the events/blocks immutably and securely. 
     As noted herein, after collection of the information regarding the vehicle by one or more nodes within a communication network, a transaction (and/or new block) including the vehicle information collected may be broadcast to the blockchain, and/or a new block verified and then added to the blockchain to reflect an updated state of the vehicle. For each of the computer-implemented methods discussed herein, in one embodiment, a transaction and/or new block may be generated and then broadcast to the blockchain network for verification once vehicle data, and/or new sensor or other data, have been generated and/or collected by one or more nodes within the communication network. As such, tracking the status of a vehicle may be more reliable and/or fraud-resistant as each node may include a proof-of-identity in its transaction modifying the state of the vehicle and/or vehicle-related blocks or blockchain. 
     Further, with the computer-implemented methods discussed herein, network participants may function as full nodes that validate and/or generate new blocks and transactions, and/or compile transactions into blocks that are then added to the network. However, not all participants need be nodes that compile transactions into blocks, and/or validate transactions and blocks received from other network participants—as some network participants may wish to rely on other network nodes to provide computer processing and/or storage services that enable usage of the system or blockchain. 
     In some scenarios, the blockchain may have public interfaces that allow visibility into the data. In one embodiment, a private blockchain interface may also be used by auto manufacturers, law enforcement, insurers, and regulatory agencies. 
     An element of smart contracts may also be enabled in the system. Depending on the sequence of events in the blockchain, terms of the smart contract may be executed immediately, such as sending a tow truck to the geolocation if tow assistance is a part of the policy, filing a legal action by a subrogation team of an insurer is brought against an auto manufacturer (for example, if an accident occurs when the autonomous vehicle was in autonomous control), conducting a policy review, filing a police report request with the jurisdiction of the roadway, processing claims awards made (for example, a partial payment if deductible is met, to handle car rental or minor medical expense), sending a renewal notice for the policy, and so on. 
     In some aspects, customers may opt-in to a rewards, loyalty, or other program. The customer may allow a remote server, such as an enforcement server, to collect sensor, telematics, image, audio, smart or autonomous vehicle, mobile device, smart or interconnected home, and other types of data discussed herein. With customer permission or affirmative consent, the data collected may be analyzed to provide certain benefits to customers. For instance, insurance cost savings may be provided to lower risk or risk averse customers. Discounts, including cryptocurrency, may be awarded to accounts associated with the customer. The other functionality discussed herein may also be provided to customers in return for them allowing collection and analysis of the types of data discussed herein, as well as participating in the validation of the data discussed herein. 
     Further to this point, although the embodiments described herein often utilize credit report information as an example of sensitive information; the embodiments described herein are not limited to such examples. Instead, the embodiments described herein may be implemented in any suitable environment in which it is desirable to identify and control specific type of information. As part of implementing the automotive claims process, vehicle loss history, and the lifecycle of a Vehicle Identification Number, a financial institution may be a part of the process. For example, the aforementioned embodiments may be implemented by the financial institution to identify and contain bank account statements, brokerage account statements, tax documents, etc. To provide another example, the aforementioned embodiments may be implemented by a lender to not only identify, re-route, and quarantine credit report information, but to apply similar techniques to prevent the dissemination of loan application documents that are preferably delivered to a client for signature in accordance with a more secure means (e.g., via a secure login to a web server) than via email. 
     With the foregoing, a user may be an insurance customer who may opt-in to rewards, insurance discount, or other type of program. After the insurance customer provides their affirmative consent, an insurance provider remote server may collect data from the customer&#39;s mobile device, smart home controller, smart or autonomous vehicle, or other smart devices—such as with the customer&#39;s permission or affirmative consent. The data collected may be related to smart or autonomous vehicle functionality, smart home functionality (or home occupant preferences or preference profiles), smart or autonomous vehicle functionality, and/or insured assets before (and/or after) an insurance-related event, including those events discussed elsewhere herein. In return, risk averse insureds, vehicle owners, home owners, or home, apartment, or vehicle occupants may receive discounts or insurance cost savings related to home, renters, personal articles, auto, mobile, health, life, and other types of insurance from the insurance provider. 
     In one aspect, smart or autonomous vehicle data, smart or interconnected home data, and/or other data, including the types of data discussed elsewhere herein, may be collected or received by an insurance provider remote server, such as via direct or indirect wireless communication or data transmission from a smart or autonomous vehicle, smart home controller, mobile device, or other customer computing device, after a customer affirmatively consents or otherwise opts-in to an insurance discount, reward, or other program. The insurance provider may then analyze the data received with the customer&#39;s permission to provide benefits to the customer. As a result, risk averse customers may receive insurance discounts or other insurance cost savings based upon data that reflects low risk behavior and/or technology that mitigates or prevents risk to (i) insureds or insured assets, such as homes, personal belongings, or vehicles, and/or (ii) home, apartment, or vehicle occupants. 
     Furthermore, although the present disclosure sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the description is defined by the words of the claims set forth at the end of this patent and equivalents. The detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical. Numerous alternative embodiments may be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims. Although the following text sets forth a detailed description of numerous different embodiments, it should be understood that the legal scope of the description is defined by the words of the claims set forth at the end of this patent and equivalents. The detailed description is to be construed as exemplary only and does not describe every possible embodiment since describing every possible embodiment would be impractical. Numerous alternative embodiments may be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims. 
     Throughout this specification, plural instances may implement components, operations, or structures described as a single instance. Although individual operations of one or more methods are illustrated and described as separate operations, one or more of the individual operations may be performed concurrently, and nothing requires that the operations be performed in the order illustrated. Structures and functionality presented as separate components in example configurations may be implemented as a combined structure or component. Similarly, structures and functionality presented as a single component may be implemented as separate components. These and other variations, modifications, additions, and improvements fall within the scope of the subject matter herein. 
     Additionally, certain embodiments are described herein as including logic or a number of routines, subroutines, applications, or instructions. These may constitute either software (e.g., code embodied on a machine-readable medium or in a transmission signal) or hardware. In hardware, the routines, etc., are tangible units capable of performing certain operations and may be configured or arranged in a certain manner. In exemplary embodiments, one or more computer systems (e.g., a standalone, client or server computer system) or one or more hardware modules of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware module that operates to perform certain operations as described herein. 
     In various embodiments, a hardware module may be implemented mechanically or electronically. For example, a hardware module may comprise dedicated circuitry or logic that is permanently configured (e.g., as a special-purpose processor, such as a field programmable gate array (FPGA) or an application-specific integrated circuit (ASIC)) to perform certain operations. A hardware module may also comprise programmable logic or circuitry (e.g., as encompassed within a general-purpose processor or other programmable processor) that is temporarily configured by software to perform certain operations. It will be appreciated that the decision to implement a hardware module mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations. 
     Accordingly, the term “hardware module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. Considering embodiments in which hardware modules are temporarily configured (e.g., programmed), each of the hardware modules need not be configured or instantiated at any one instance in time. For example, where the hardware modules comprise a general-purpose processor configured using software, the general-purpose processor may be configured as respective different hardware modules at different times. Software may accordingly configure a processor, for example, to constitute a particular hardware module at one instance of time and to constitute a different hardware module at a different instance of time. 
     Hardware modules may provide information to, and receive information from, other hardware modules. Accordingly, the described hardware modules may be regarded as being communicatively coupled. Where multiple of such hardware modules exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) that connect the hardware modules. In embodiments in which multiple hardware modules are configured or instantiated at different times, communications between such hardware modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware modules have access. For example, one hardware module may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware module may then, at a later time, access the memory device to retrieve and process the stored output. Hardware modules may also initiate communications with input or output devices, and may operate on a resource (e.g., a collection of information). 
     The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented modules that operate to perform one or more operations or functions. The modules referred to herein may, in some example embodiments, comprise processor-implemented modules. 
     Similarly, the methods or routines described herein may be at least partially processor-implemented. For example, at least some of the operations of a method may be performed by one or more processors or processor-implemented hardware modules. The performance of certain of the operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processor or processors may be located in a single location (e.g., within a home environment, an office environment or as a server farm), while in other embodiments the processors may be distributed across a number of locations. 
     The performance of certain of the operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the one or more processors or processor-implemented modules may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the one or more processors or processor-implemented modules may be distributed across a number of geographic locations. 
     Unless specifically stated otherwise, discussions herein using words such as “processing,” “computing,” “calculating,” “determining,” “presenting,” “displaying,” or the like may refer to actions or processes of a machine (e.g., a computer) that manipulates or transforms data represented as physical (e.g., electronic, magnetic, or optical) quantities within one or more memories (e.g., volatile memory, non-volatile memory, or a combination thereof), registers, or other machine components that receive, store, transmit, or display information. 
     As used herein any reference to “one embodiment” or “an embodiment” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment. 
     Some embodiments may be described using the expression “coupled” and “connected” along with their derivatives. For example, some embodiments may be described using the term “coupled” to indicate that two or more elements are in direct physical or electrical contact. The term “coupled,” however, may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other. The embodiments are not limited in this context. 
     As used herein, the terms “includes,” “comprising,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that includes a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present). 
     In addition, use of the “a” or “an” are employed to describe elements and components of the embodiments herein. This is done merely for convenience and to give a general sense of the description. This description, and the claims that follow, should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise. 
     The patent claims at the end of this patent application are not intended to be construed under 35 U.S.C. § 112(f) unless traditional means-plus-function language is expressly recited, such as “means for” or “step for” language being explicitly recited in the claim(s).
