Title: Systems and methods for smart card mobile device authentication

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is related to and claims priority to U.S. Provisional Patent Application No. 62/135,594, entitled “SYSTEMS AND METHODS FOR SMART CARD MOBILE DEVICE AUTHENTICATION,” filed on Mar. 19, 2015, which is herein incorporated by reference in its entirety and for all purposes. 
    
    
     BACKGROUND 
     Financial institutions such as banks typically offer their customers a variety of payment alternatives to meet their needs. One such alternative is for the financial institution to offer the customer a payment card that provides the customer with quick and convenient access to a charge account from multiple locations where the card is accepted. Charge accounts can include, for example, lines of credit, checking accounts, temporary prepaid accounts, and so on. The card issuer typically provides the customer with a plastic card or other device having an account number associated therewith, and establishes a corresponding charge account for the customer. The card or other device may be used by the customer to purchase goods and services by charging the charge account. The card issuer authorizes payment for the goods or services and then enters a debit to the charge account. 
     Many mobile devices such as cell phones include software applications and hardware sufficient to provide a mobile pay function. Mobile pay functions allow users to purchase goods and services from physical merchants with their mobile devices, using funds from their charge accounts in the absence of a physical payment card. A given user can enter payment card information into their mobile device, which may then be subsequently used to transmit the payment card information to a merchant&#39;s point of sale to facilitate a transaction without having to provide the actual payment card to the merchant. 
     Payment card information sufficient to enable the mobile pay service can often be found on the face of the payment card itself. As such, an unauthorized user with visual or temporary access to a payment card may be able to activate a mobile pay service associated with that payment card on their own mobile device (e.g., by taking a digital image of the payment card or writing down the payment card information, and activating mobile pay later on) and proceed with unauthorized purchases. 
     SUMMARY 
     One example embodiment relates to a method of authenticating a mobile pay feature on a mobile device. The method includes offering, by a mobile pay circuit, a mobile pay functionality.

     DETAILED DESCRIPTION 
     According to various embodiments, systems and methods for authenticating a mobile pay function on a mobile device is provided. In some arrangements, the mobile pay function stores a user&#39;s personal and payment card information on an associated mobile device, and allows the mobile device to wirelessly transmit payment information to a merchant&#39;s point of sale to facilitate a purchase of goods or services, or to perform other financial operations relating to the underlying charge account. Consistent among the embodiments discussed below, a “smart” payment card is physically present during the initial mobile pay authentication process. 
     Referring now to  FIG. 1 , a block diagram of an authentication and transaction system  100  is shown according to an example embodiment. The authentication and transaction system  100  includes a mobile device  102 , a smart card  104 , a network  106 , and a card issuer computing system  108 . The mobile device  102  may include, for example, mobile phones, smartphones, tablets, wearable computing devices (e.g., eyewear, smart watches, etc.), laptop computers, and so on. A common feature of the mobile device  102  is the ability to access the network  106  in order to send and receive data to and from the card issuer computing system  108 , including authentication requests. The network  106  may include wireless networks (e.g., cellular networks, Bluetooth®, WiFi, Zigbee®, etc.), wired networks (e.g., Ethernet, DSL, cable, fiber-based, etc.), or a combination thereof. In some arrangements, the network  106  includes the internet. 
     The mobile device  102  includes a mobile pay circuit  110 . The mobile pay circuit  110  may include program logic executable by a processor of the mobile device  102  to implement at least some of the functions described herein. In order to make the mobile pay circuit  110 , a third party provider (e.g., a software developer or publisher) can make a software application available to be placed on the mobile device  102 . For example, a software developer may make the software application available to be downloaded (e.g., via the developer&#39;s website, via an app store, or in another manner). In some arrangements, the third party provider is the card issuer or financial institution associated with the smart card  104 . Responsive to a user selection of an appropriate link, the software application can be transmitted to the mobile device  102  and cause itself to be installed on the mobile device  102 . Installation of the software application creates the mobile pay circuit  110  on the mobile device. Specifically, after installation, the thus-modified mobile device  102  includes the mobile pay circuit  110  (embodied as a processor and instructions stored in non-transitory memory that are executed by the processor). 
     The mobile device  102  further includes contactless logic  112 . The contactless logic  112  includes hardware and associated software sufficient to enable the mobile device  102  to wirelessly and securely exchange data over short distances (e.g., within a range of a few inches or less). In some arrangements, the contactless logic  112  is configured to use radio frequency identification (RFID) to exchange digital information. In some such arrangements, the contactless logic  112  enables the mobile device  102  to exchange data over a radio frequency range required for near field communication (NFC). In some arrangements, the mobile pay circuit  110  includes instructions to selectively employ the contactless logic  112  to send or receive information. 
     The smart card  104  is a payment card associated with a charge account (e.g., a line of credit, a checking account, a prepaid account, and the like) for a given customer, and is capable of wirelessly exchanging information. The smart card  104  can include visible information on the face of the card and digital information stored within various structures in the smart card  104  itself. For example, the smart card  104  can include a customer&#39;s name and a payment card account number, which can be printed or embossed on the physical card. Further, the smart card  104  can include more detailed identifying customer information (e.g., name, address, phone number, and so on) and account information (e.g., account numbers, information as to the card issuer, and so on) in a magstrip, or an onboard contactless chip  115 . For example, the smart card  104  can be a credit card, a debit card, or the like. 
     The contactless chip  115  is a defining feature of the “smart” aspect of the smart card  104 . The contactless chip  115  is a small circuitry system configured to wirelessly exchange data. In some arrangements, the contactless chip  115  can exchange data via RFID or NFC communication. The contactless chip  115  can be configured to be able to selectively transmit various types of information, including payment card information (e.g., account numbers, issuing entities, and so on), identifying customer information (e.g., user name, billing address, phone number, and so on), cryptograms, an authentication code, and the like to other devices (e.g., to the mobile device  102 , to the point of sale system  122 , etc.). Such arrangements can be found in existing smart card functions provided by, for example, Visa payWave™ Mastercard PayPass™, and American Express ExpressPay™. 
     The contactless chip  115  can also be configured to transmit an authentication code  114 . The authentication code  114  can include payment card information and identifying customer information, along with a cryptogram, which in some arrangements, is a sequence of characters that have been encoded through one or more algorithms to conceal data from unauthorized parties. 
     The card issuer computing system  108  is a computing system at a financial entity that issued the smart card  104  to a customer. In the context of the present disclosure, the financial entity can include financial institutions such as commercial or private banks, credit unions, investment brokerages, and so on, but can also include any commercial entity capable of maintaining charge accounts, including merchants, service providers, and the like. The card issuer computing system  108  is configured to manage charge accounts and to authenticate transactions involving debits from charge accounts associated with existing customers. 
     The card issuer computing system  108  includes an issuer network logic  116 , an authentication logic  118 , and a customer database  120 . The issuer network logic  116  is configured to enable the card issuer computing system  108  to exchange information over the network  106 . The customer database  120  can be configured to contain information for a plurality of customers with issued smart cards, including for example, personal customer information (e.g., names, addresses, phone numbers, and so on) and customers&#39; financial information (e.g., associated financial institutions, account numbers, available credit, credit history, and so on). The information contained in the customer database  120  is sufficient for the card issuer computing system  108  to perform a variety of checks surrounding a given smart card transaction, including for example, confirming identifying customer information, determining a customer&#39;s transaction history, determining a customer&#39;s available credit, and so on. 
     The authentication logic  118  is configured to perform operations relating to transactions involving the smart card  104 . For example, the authentication logic  118  can be configured to receive an authentication request from the mobile pay circuit  110  over the network  106  via the issuer network logic  116 . In some such arrangements, the authentication request includes the authentication code  114  with a cryptogram. The authentication logic  118  may then decrypt a received cryptogram included in the authentication code  114 , verify the resulting data and the rest of the information in the authentication code  114  using information in the customer database  120 , approve or deny the authentication request, and push the approval or denial back to the mobile pay circuit  110 . 
     In operation, a customer seeking to activate a mobile pay function on the mobile device  102  can install a mobile pay application giving rise to the mobile pay circuit  110 . In some arrangements, the mobile pay circuit  110  is configured to cause the mobile device  102  to present a graphical user interface on an associated display, prompting the customer to set up a mobile pay account. As part of the setup process, in some arrangements, the graphical user interface can prompt the customer to enter identifying information (e.g., name, address, phone number, etc.), which may be accomplished through an input device associated with the mobile device  102  (e.g., a touchscreen, a physical keyboard, voice recognition, or the like). Further, the graphical user interface may be configured to prompt the customer to enter payment card information for the smart card  104 . In some arrangements, the graphical user interface may require the customer to manually enter the payment card information (e.g., a sixteen-digit payment card number, expiration date, CCV number, etc.) in the same manner as the identifying information (i.e., manually via an input device). In other arrangements, the graphical user interface prompts the user to take a picture of the smart card and the mobile pay application performs optical character recognition to identify the payment card information. 
     As part of the setup process, the mobile pay circuit  110  communicates with the contactless chip  115  on the smart card  104  to receive the authentication code  114  via the contactless logic  112 . As discussed above, the authentication code  114  can include a cryptogram. The authentication code  114  can also include identifying customer information (e.g., name, billing address, phone number, and so on) and payment card information (e.g., charge account number, issuing entity, and so on) to provide sufficient information for the mobile pay function on the mobile device  102  to operate. In some such arrangements, the non-cryptogram information in the authentication code  114  (e.g., the payment card information, the customer information, etc.) does not need to be manually entered by a user, and may automatically be populated in the appropriate fields of the graphical user interface upon a contactless transmission of the authentication code  114 . The contactless chip  115  transmits the authentication code  114  to the mobile pay circuit  110  of the mobile device  102  by, for example, being brought within a threshold proximity to the mobile device  102  sufficient to establish a wireless data handshake where data exchange between the contactless logic  112  of the mobile device  102  and the contactless chip  114  on the smart card  104  occurs (e.g., via RFID, NFC, or the like). Upon receiving a wireless signal transmission of a data payload including the authentication code  114  from the contactless chip  115 , the contactless logic  112  can route the authentication code  114  to the mobile pay circuit  110 . 
     In one arrangement, the mobile pay circuit  110  receives an authentication code  114  that includes a cryptogram intended to be used for authenticating the smart card  104 . In such an arrangement, the mobile pay circuit  110  may transmit the cryptogram to the card issuer computing system  108  in an authentication request over the network  106 . In some such arrangements, the authentication request is a transaction authorization request entailing a charge of little to no funds (e.g., a transaction of $0.01, or a transaction of $0.00). The authentication logic  118  at the card issuer computing system  108  can receive what appears to be a normal transaction authorization request (i.e., not meaningfully distinguishable from an actual purchase transaction at a point of sale system) and proceed to process the authentication request as a transaction authorization request. As such, the authentication logic  118  may not have to be altered or tailored to address authentication request from a mobile device  102 , but can simply apply existing transaction authorization procedures instead. The authentication logic  118  can proceed to decrypt the cryptogram from the authentication code  114 , and confirm that the resulting data corresponds to the smart card  104  and the user (i.e., the user attempting to enable a mobile pay function on the mobile device  102 ) by, for example, retrieving data from the customer database  120 . In some such arrangements, the authentication logic  118  can recognize that a requested transaction of $0.00 (or $0.01) indicates an attempt to enable a mobile pay feature on a mobile device and apply a specific set of authentication rules. If the authentication request passes all of the authentication rules at the card issuer computing system  108 , the authentication logic  118  can transmit an authentication approval back to the mobile device  102  over the network  106  via the issuer network logic  116 . In some arrangements, the authentication approval includes payment card information sufficient to complete future purchase transactions via the mobile device  102 . 
     Further, in some arrangements, the mobile pay circuit  110  can take additional authentication steps at the mobile device  102  to supplement the authentication process occurring at the card issuer computing system  108 . For example, the mobile pay circuit  110  can, for example, require the customer to enter a PIN number, biometric data, or answers to identification questions into a graphical user interface in the mobile device  102 . In addition, the mobile pay circuit  110  can compare identifying customer information contained in the authentication code  114  received from the contactless chip  115  to identifying customer information stored in the mobile device  102  (e.g., where the mobile device is registered under a given individual, accounts configured in various mobile applications in the mobile device  102 , and the like). 
     Upon receiving an authentication approval from the card issuer computing system  108 , the mobile pay circuit  110  can confirm that the user and the mobile device  102  is authorized to access and use the charge account(s) associated with the smart card  104 . In which case, the mobile pay circuit  110  can enable the mobile pay function on the mobile device to complete purchase transactions. In some arrangements, financial transactions can subsequently be completed via the contactless logic  112  at a point of sale  122 . The point of sale  122  is a computing system at a merchant of goods or services configured to facilitate customer transactions. The point of sale  122  includes a contactless device  126 . The contactless device  126  includes hardware and software sufficient to enable the point of sale  122  to wirelessly exchange information with the contactless logic  112  of the mobile device  102 . In one arrangement, the point of sale  122  also includes a database containing product and/or service information provided by a given merchant, such as quantity of units available, price, and so on. Further, the point of sale  122  can also include a display, which can take the form of any of several types of devices, including LCD, LED, CRT, plasma, or other such digital displays, projection-based monitors, touchscreens, and so on. In some arrangements, the display and/or the database is included in a merchant&#39;s smartphone. 
     In operation, after enabling a mobile pay function on the mobile device  102 , a customer can identify a merchant&#39;s good at the point of sale  122  and attempt to purchase it. The point of sale  122  may be configured to retrieve information as to the identified good, including price, from an associated database and present the information on a display, and prompt the merchant to request payment. The customer can bring the mobile device  102  within a threshold proximity to the contactless device  124  to allow the mobile pay circuit  110  to transmit payment information associated with the smart card  104  to the point of sale  122  via the contactless logic  112  to complete a transaction for the sale of the identified good. 
     In some arrangements, after receiving an authentication approval from the card issuer computing system  108 , the mobile pay circuit  110  can allow a user to perform additional operations through the mobile device  102  beyond purchase transactions. For example, because the mobile pay circuit  110  has authenticated the user and the mobile device  102  to use the smart card  104 , the mobile pay circuit  110  can also allow the mobile device  102  to access information relating to the charge account associated with the smart card  104 . In some such arrangements, an authenticated user may not need to enter a username and password to access a charge account webpage on a card issuer website or software application. As such, an authenticated user may be able to view information such as account balances, available credit, payment due dates, and so on through the mobile device  102  without having to manually log in. Further, in some arrangements where the card issuer computing system  108  is a financial institution where the user also has one or more non-credit based accounts (e.g., checking accounts, savings accounts, or the like), an authenticated user can also authorize the mobile device  102  to perform related banking transactions (e.g., transfer funds, pay bills, view statements, and so on) or change user account settings (e.g., changing usernames and passwords, email preferences, and so on). 
     Referring now to  FIG. 2 , an example graphical user interface  200  generated by a mobile pay circuit (e.g., mobile pay circuit  110 ) on a mobile device  102  is shown according to one example embodiment. The graphical user interface  200  shown includes a plurality of instructions and fields directed to allow a user to enable a mobile pay feature on the mobile device  102 . For example, the interface  200  includes instructions and fields for information that can be entered manually (e.g., via a keyboard, a touchscreen, voice commands, and so on), such as a customer name  202 , a charge account username  210 , a charge account password  212 , and a fingerprint  214 . Interface  200  also includes several instructions and fields whose manual entry may be optional (e.g., a card number  204 , an expiration date  206 , and a card verification code  208 ). These fields may be automatically populated or manually entered and subsequently confirmed upon receiving a contactless transmission from the user&#39;s smart card (e.g., the authentication code  114  from the contactless chip  115  on the smart card  104 ). As shown by a notification  216  at the bottom of the interface  200 , a contactless transmission has not yet been received by the mobile device  102 , and as such, all of the payment card fields are blank. In addition, as implicitly shown by a dashed enabling trigger  218 , the mobile pay function cannot be enabled in the current state of the mobile device  102  without a contactless transmission from a smart card. 
     Referring now to  FIG. 3 , a flowchart of a method  300  of enabling, authenticating, and using a mobile pay feature on a mobile device to purchase goods or services is shown. The method  300  is performed by processing and storage hardware on a user mobile device (e.g., mobile device  102 ), as executed by one or more logics comprising one or more software applications configured to perform the functions described below. 
     At  302 , a mobile pay function is offered to a user. Mobile pay is a function on the mobile device that allows a user to use a contactless transmission-enabled mobile device to perform financial transactions at a point of sale system (e.g., the point of sale system  122 ) based on a charge account in the physical absence of the corresponding payment card. In one arrangement, a mobile pay function is offered on a mobile device after a software application obtained from an app store or a developer portal assembles a mobile pay circuit (e.g., mobile pay circuit  110 ) in the mobile device. In other arrangements, the mobile pay circuit is preconfigured in the mobile device prior to a user purchasing the mobile device, precluding the need for the user to download and install a software application to create the mobile pay circuit. The mobile pay circuit can be configured to cause the mobile device to offer mobile pay by providing one or more notifications or user interfaces to a user, informing the user that the mobile device is capable of a mobile pay function. The notifications can take the form of, for example, a pop-up notification, a page in a tutorial, or a toggle or interface within a mobile device settings or options interface. 
     At  304 , the user registers with the mobile pay function of the mobile device. The user provides affirmative user input to the mobile device indicating that the user wishes to register for mobile pay. The affirmative user input includes one or more physical user inputs (e.g., keystrokes, touchscreen presses, voice commands, and so on) received at a mobile device indicating that the user desires to enable the mobile pay functionality in the mobile device. The affirmative user input can be in response to the notifications provided at  302  (e.g., pressing a toggle, button, or link appearing on the display, or selecting a displayed option in a settings menu, or the like). During the registration, the user provides identifying user information (e.g., user name, address, phone number, or the like) and payment card information (e.g., account number, expiration date, CCV, etc.) to the mobile device. The information may be provided through manual user input by the user (e.g., via the touchscreen or keyboard) and/or by taking a picture of the payment card through a camera of the mobile device. In situations in which the payment card information is provided through the camera of the mobile device, the mobile device can perform optical character recognition to identify the payment card information. 
     At  306 , an authentication code (e.g., authentication code  114 ) is received as a contactless transmission from a smart card. The authentication code is received by a mobile pay circuit via a contactless logic (e.g., contactless logic  112 ) at the mobile device. The authentication code can include at least one cryptogram along with other types of information (e.g., identifying user information, payment card information, and so on) as discussed with respect to  FIG. 1 , above. The authentication code is received after a smart card is brought within a threshold proximity to the mobile device such that a contactless transmission is possible (e.g., within a few inches or even touching the smart card to the mobile device). When the user brings the smart card within sufficient proximity to the mobile device, a wireless data link is established between the smart card and the mobile device, and the smart card can pass a data payload having the authentication code to the mobile device (e.g., via RFID, NFC, or the like). 
     At  308 , a smart card is authenticated. The smart card is authenticated based on the received payment card information (received at  304 ) and the authentication code (received at  306 ). The received information and authentication code are used to determine whether the mobile device associated with the user and/or the user himself is authorized to perform transactions with the smart card. In one arrangement, the smart card is authenticated by decrypting an authentication code to reveal a user name, a payment card account number, and a cryptogram. The decrypted information can then be used, for example, to compare corresponding information manually entered into the mobile device by the user (e.g., the user name), or by transmitting an authentication request (i.e., including the cryptogram) to a corresponding card issuer computing system (e.g., card issuer computing system  108 ). Decrypted authentication code information (e.g., a user name and billing address) can also be compared with account information stored in the mobile device itself (e.g., email accounts, cellular network accounts, and so on). In arrangements where the mobile device passes the received information on to the card issuer computing system, the mobile device may receive an authentication decision from the card issuer (e.g., an authorized or not authorized decision message). 
     At  310 , a mobile pay function is enabled. Enabling the mobile pay function upon successfully authenticating the smart card allows a corresponding mobile device to complete mobile pay transactions. The mobile device can serve as a proxy for the physical payment card such that the user does not need to present the payment card at a point of sale system (e.g., the point of sale system  122 ). 
     At  312 , a mobile pay transaction is performed. As noted above, the mobile device can be used in place of the payment card. As such, placing the mobile device within a threshold proximity of a contactless transmission-enabled point of sale will allow the point of sale to pull payment information from the mobile device or the mobile device to push payment information to the point of sale sufficient to complete a transaction involving a debit incurred on a user&#39;s charge account. Further, in some arrangements, a successful smart card authentication will enable several financial operations on the mobile device, such as accessing charge account information (e.g., balances, available credit, due dates, and so on) and performing charge account actions (e.g., transferring balances, paying bills, changing a username or password, and so on), without requiring the user to provide login information. 
     Referring to  FIG. 4 , a flowchart of a method  400  of authenticating a mobile device for a mobile pay function is shown according to an example embodiment. The method  400  is performed by processing and storage hardware of a card issuer computing system (e.g., the card issuer computing system  108 ), as executed by one or more logics comprising one or more software applications configured to perform the functions described below. 
     The method  400  begins when an authentication request for a mobile pay function is received at  402 . The card issuer computing system receives the authentication request from a mobile device (e.g., the mobile device  102 ) attempting to activate a mobile pay feature (e.g., a mobile pay application installed on the mobile device). The authentication request includes user information and payment information. The user information includes a user name, address, phone number, and so on. In some arrangements, the user information includes a unique identifier associated with the mobile device (e.g., a mobile device MAC address). The payment information includes account information associated with a payment card (e.g., the smart card  104 ). The account information, for example, may include an account number (e.g., a credit card primary account number), an account expiration date, a CCV number, an account holder name, and the like. The payment information also includes an authentication code. The authentication code was generated by the smart card and transmitted to the mobile device (e.g., during an RFID or NFC communication session between the smart card and the mobile device as described above with respect to  FIG. 1 ). The authentication code can include payment card information and identifying customer information, along with a cryptogram, which in some arrangements, is a sequence of characters that have been encoded through one or more algorithms to conceal data from unauthorized parties. The authentication code serves as an indicator that the payment card was present at the mobile device thereby indicating that the user did not simply key in the payment information based on an image of the card or knowledge of the account information. 
     The information received with the authentication request is verified at  404 . The card issuer computing system compares the received user information with known user information associated with the account number of the payment card. For example, the card issue computing system verifies the provided name and address of the user with the known name and address of the account holder associated with the payment card. Additionally, the issuer computing system decodes the authentication code to verify that the authentication code was generated by the payment card (i.e., that the authentication code was not fraudulently created). In some arrangements, the card issuer computing system also compares the mobile device unique identifier with a known mobile device unique identifier associated with the account holder of the payment card (e.g., based on other payment cards registered with the mobile device, etc.). 
     An authentication decision is transmitted at  406 . If any of the information provided does not match known information or cannot be otherwise verified at  404 , the request to activate the mobile pay function is denied. In such situations, the card issuer computing system transmits a denial message to the mobile device, which prevents the mobile pay function from functioning on the mobile device with the provided payment card. If all of the information provided matches known information and can be otherwise verified at  404 , the request to activate the mobile pay function is approved. In such situations, the card issuer computing system transmits an approval message to the mobile device, which thereby activates the mobile pay function on the mobile device for the provided payment card. When the mobile pay function is activated, the user can use the mobile device as a proxy for the payment card as described above with respect to  FIGS. 1 and 3 .

However, describing the embodiments with drawings should not be construed as imposing on the disclosure any limitations that may be present in the drawings. 
     It should be understood that no claim element herein is to be construed under the provisions of 35 U.S.C. § 112(f), unless the element is expressly recited using the phrase “means for.” 
     As used herein, the term “circuit” may include hardware structured to execute the functions described herein. In some embodiments, each respective “circuit” may include machine-readable media for configuring the hardware to execute the functions described herein. The circuit may be embodied as one or more circuitry components including, but not limited to, processing circuitry, network interfaces, peripheral devices, input devices, output devices, sensors, etc. In some embodiments, a circuit may take the form of one or more analog circuits, electronic circuits (e.g., integrated circuits (IC), discrete circuits, system on a chip (SOCs) circuits, etc.), telecommunication circuits, hybrid circuits, and any other type of “circuit.” In this regard, the “circuit” may include any type of component for accomplishing or facilitating achievement of the operations described herein. For example, a circuit as described herein may include one or more transistors, logic gates (e.g., NAND, AND, NOR, OR, XOR, NOT, XNOR, etc.), resistors, multiplexers, registers, capacitors, inductors, diodes, wiring, and so on). 
     The “circuit” may also include one or more processors communicatively coupled to one or more memory or memory devices. In this regard, the one or more processors may execute instructions stored in the memory or may execute instructions otherwise accessible to the one or more processors. In some embodiments, the one or more processors may be embodied in various ways. The one or more processors may be constructed in a manner sufficient to perform at least the operations described herein. In some embodiments, the one or more processors may be shared by multiple circuits (e.g., circuit A and circuit B may comprise or otherwise share the same processor which, in some example embodiments, may execute instructions stored, or otherwise accessed, via different areas of memory). Alternatively or additionally, the one or more processors may be structured to perform or otherwise execute certain operations independent of one or more co-processors. In other example embodiments, two or more processors may be coupled via a bus to enable independent, parallel, pipelined, or multi-threaded instruction execution. Each processor may be implemented as one or more general-purpose processors, application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), digital signal processors (DSPs), or other suitable electronic data processing components structured to execute instructions provided by memory. The one or more processors may take the form of a single core processor, multi-core processor (e.g., a dual core processor, triple core processor, quad core processor, etc.), microprocessor, etc. In some embodiments, the one or more processors may be external to the apparatus, for example the one or more processors may be a remote processor (e.g., a cloud based processor). Alternatively or additionally, the one or more processors may be internal and/or local to the apparatus. In this regard, a given circuit or components thereof may be disposed locally (e.g., as part of a local server, a local computing system, etc.) or remotely (e.g., as part of a remote server such as a cloud based server). To that end, a “circuit” as described herein may include components that are distributed across one or more locations. 
     An exemplary system for implementing the overall system or portions of the embodiments might include a general purpose computing computers in the form of computers, including a processing unit, a system memory, and a system bus that couples various system components including the system memory to the processing unit. Each memory device may include non-transient volatile storage media, non-volatile storage media, non-transitory storage media (e.g., one or more volatile and/or non-volatile memories), etc. In some embodiments, the non-volatile media may take the form of ROM, flash memory (e.g., flash memory such as NAND, 3D NAND, NOR, 3D NOR, etc.), EEPROM, MRAM, magnetic storage, hard discs, optical discs, etc. In other embodiments, the volatile storage media may take the form of RAM, TRAM, ZRAM, etc. Combinations of the above are also included within the scope of machine-readable media. In this regard, machine-executable instructions comprise, for example, instructions and data which cause a general purpose computer, special purpose computer, or special purpose processing machines to perform a certain function or group of functions. Each respective memory device may be operable to maintain or otherwise store information relating to the operations performed by one or more associated circuits, including processor instructions and related data (e.g., database components, object code components, script components, etc.), in accordance with the example embodiments described herein. 
     It should also be noted that the term “input devices,” as described herein, may include any type of input device including, but not limited to, a keyboard, a keypad, a mouse, joystick or other input devices performing a similar function. Comparatively, the term “output device,” as described herein, may include any type of output device including, but not limited to, a computer monitor, printer, facsimile machine, or other output devices performing a similar function.
