The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology. 
     To protect important information, utilizing storage on cloud networks is one approach to provide data redundancy. For sensitive information may be stored in an encrypted form. Blockchain leverages both cloud networks and encryption to define storage of all information in a block wise manner The blocks are added to the blockchain in a linear and chronological order. The blockchain helps to store and track data in a secured manner. Currently, the blockchain is used in various fields such as gaming and gambling, diamond industry, real estate, medical industry, or e-voting. 
     Further, utilization of the blockchain with the various fields involves numerous devices for updating the information. Further, it becomes tedious to maintain a high security when the updated information is accessed by multiple parties through the devices. Therefore, there is a need for an improved system that may provide protection to the seamlessly updated data accessed by the multiple parties.

       FIG. 3  illustrates a method for hybrid encryption of data, in accordance with various embodiments. During the method, both symmetric encryption and asymmetric encryption techniques may be used in tandem. In various embodiments, the symmetric encryption technique may be used to encrypt data  302  using a symmetric key  304  for producing encrypted data  306 . The encrypted data  306  may be decrypted using another symmetric key  308  for obtaining back data  302 . Further, a public key  310  may be used to encrypt the symmetric key  304  and a private key  312  may be used to encrypt the symmetric key  308 , stored as an encrypted key  314 . The public key  310  and the private key  312  may form a key pair  316 . In some embodiments, any one or more of keys  304  and  308 , public key  310 , private key  312 , and key pair  316  may be stored in a key database that is part of a blockchain database (e.g., key database  130   b ). 
     In some embodiments, the steps illustrated in  FIG. 3  may be initiated by users who generate a new profile on the blockchain network. Private keys may be stored in decentralized and distributed hashes through the blockchain network. In some embodiments, the steps illustrated in  FIG. 3  may be partially performed in either one of devices  102  and  104 , in HIE server  106 , or in network server  108 . For example, in some embodiments, HIE server  106  may install a software development kit (SDK) or a key generator application in devices  102  or  104  to perform at least some of the steps illustrated in  FIG. 3 . Likewise, keys  204 ,  208 , and key pair  210  may be stored in a memory of either one of devices  102  and  104 , in HIE server  106 , or in network server  108 , or in an associated database (e.g., any one of databases  102   b ). 
       FIG. 4  illustrates a system  401  for storing and accessing data in a health care network, according to various embodiments. A first level subsystem  401 - 1  may include a core service component  402  and a Remote Procedure Call (RPC) component  404 . A second level subsystem  401 - 2  may include a blockchain node  406 . In various embodiments, first level subsystem  401 - 1  may include the core service component  402 , and second level subsystem  401 - 2  may include the RPC component  404  and the blockchain node  406 . To access blockchain node  406 , user device  102  and a second user device  420  (e.g., a third party using a desktop) may place a remote call to RPC component  404 . Blockchain node  406  may be a public node or a private node in a blockchain network having a layer over a public blockchain network, enabling the private node to perform private transactions via consensus algorithms (e.g., a Quorum blockchain node). Further, the core service component  402  of first level subsystem  401 - 1  may be present in communication with third-party servers and databases of a hospital computing network  408 . The hospital computing network  408  may include a file system module  410 , an EHR synchronization service  412 , and a blockchain node  414  (e.g., a Quorum blockchain node). Further, the file system module  410  may include a file system manager  416  and a file system node  418 . The blockchain node  406  of second level subsystem  401 - 2  may communicate with the blockchain node  414  of the hospital computing network  408 . Patients may access the health care network for storing data through the user device  102 , and a representative of a hospital may access the health care network through another user device  420 . 
     In accordance with various embodiments, the representative of the hospital may want to synchronize Electronic Health Record (EHR) data of a patient, e.g., by using corresponding blockchain hashes. Successively, first level subsystem  401 - 1  and second level subsystem  401 - 2  may ask the patient for permission to allow a representative of the hospital to store the EHR data of the patient, through the file system module  410 . Based at least on the permission granted by the patient, a signed transaction may be created to confirm the permission of the hospital to store the EHR data. Further, the signed transaction may activate a smart contract that may add hospital identification information such as a blockchain address to a list of permitted users. In some embodiments, the signed transaction and the smart contract are stored in file system module  410 . 
     Further, the signed transaction may be transmitted from the user device  102  to the RPC component  404  of the first level subsystem and/or the second level subsystem. The RPC component  404  may communicate the signed transaction to the blockchain node  406  of the second level subsystem. This may be done successively. The blockchain node  406  may activate one or more smart contracts. This may be done successively. Thereafter, the blockchain node  406  may revise a state of one or more blockchains. 
     Further, based at least on the permission granted by the patient, the EHR synchronization service may obtain a list of patients from the RPC component  404 . Further, the EHR synchronization service may confirm whether the patient has granted permission. Based at least on the permission, the first level subsystem and the second level subsystem may obtain the EHR data and may calculate a hash function for the EHR data. The HIE server  106  may match the hash function of the EHR data with a hash function for the patient blockchain on the blockchain node  406  of the second level subsystem. This may be done successively. Thereafter, if the hash function of the EHR data matches with the hash function for the patient blockchain on the blockchain node  406  of the second level subsystem, the EHR data of the patient may remain unchanged. 
       FIG. 5  illustrates a system for storing and accessing data in a health care network implemented, for example, over a blockchain network, according to various embodiments (cf.  FIGS. 1 and 4 ). In some embodiments, the HIE server  106  may execute an application for determining permission from the user for obtaining EHR data  502 . In various embodiments, if the user grants the permission, the HIE server  106  may obtain the EHR data  502  for calculating a hash function for the EHR data  502 . Further, the HIE server  106  may match the hash function of the EHR data  502  with a hash function for the user blockchain on the blockchain node of the second level sub-system. In various embodiments, if the two hash matches, there is no change to the user&#39;s EHR data  502 . In various embodiments, the two hash functions do not match, the HIE server  106  may generate a random string e,g, secret key  504 , through a random key generator  506 . Accordingly, in some embodiments secret key  504  may be a random string. The secret key  504  may be used for Advanced Encryption Standard (AES) encryption of the EHR data  502 , in an AES encryptor  508 , for generating encrypted EHR data  510 . 
     In accordance with various embodiments, the secret key  504  may then be encrypted by a Rivest-Shamir-Adleman (RSA) public key  512  of the patient, in an RSA encryptor  514 , to generate an encrypted secret key  516 . The HIE server  106  may further send the encrypted EHR data  510  to the core service component  402  for forwarding the data to the file system manager  416  of the hospital computing network  408  for storage. Further, the file system manager  416  may send a file system hash function to the core service component  402  for further sending the Inter Planetary File System (IPFS) hash function to EHR synchronization service  412 . The EHR synchronization service  412  may further update the patient smart contract with the new file system hash function, the encrypted random key, a hash function of the unencrypted file, and file name. 
     In accordance with various embodiments, a hospital representative, such as a doctor or a hospital administration, may want to view the EHR data  502 . In such a scenario, the user may first send a signed transaction to a RPC component  404  for granting permission to the hospital representative to view the EHR data  502 . Once the permission is granted, the signed transaction may be added to the blockchain node  414  and a new smart contract will be created for a blockchain corresponding to the hospital representative. After adding the signed transaction, the hospital representative may be able to view the EHR data  502  of the user, on a device. 
     In accordance with various embodiments, in order to view the EHR data  502  on the device, the HIE server  106  may collect the encrypted EHR data  510  from the user&#39;s blockchain and may decrypt the encrypted EHR data  510  using patient&#39;s RSA private key  518 . The HIE server  106  may decrypt the encrypted secret key  516 , in an RSA decryptor  520 , using RSA private key of the hospital representative. The encrypted EHR data  510  may be decrypted using the RSA public key  512  of the hospital representative, in an AES decryptor  522 . This may be done successively. Further, the HIE server  106  may load the decrypted EHR data  502  to the smart contract previously created for the hospital representative. 
     Post loading, the RPC component  404  may obtain the signed transaction from the patient&#39;s user device and transmit the signed transaction to the blockchain node  406  of the second level subsystem. The blockchain node  406  may confirm ownership of the signed transaction and may execute the smart contract for the hospital representative to view the user&#39;s health information. This may be done successively. 
     In accordance with various embodiments, the patient may decline permission for the hospital representative to access the EHR data  502 . In such a scenario, the user, through a user device, may send a signed transaction revoking permission to the RPC component  404 . The RPC component  404  may forward the signed transaction to the blockchain node  406  of the second level subsystem. This may be done successively. The blockchain node  406  may confirm ownership of the signed transaction and may delete the smart contract previously created to allow the hospital representative to have access to the patient&#39;s EHR data  502 . This may be done successively. 
     Further, the HIE server  106  may include a health record network for an intermediary enabling sharing of user&#39;s medical records with providers. For enabling sharing, the user may grant specific permissions to the providers for accessing parts of the user&#39;s medical records stored in a user database (not shown) implemented over a blockchain network. The user may also grant specific permissions to modify the user&#39;s medical records in the user database.
