A method and a system for conducting a transaction using an electronic chip are provided. One or more details of a plurality of payment modes and a first authentication parameter are stored in the electronic chip. The electronic chip receives an authentication request including a second authentication parameter from a terminal device when the transaction is initiated at the terminal device. The electronic chip compares the first and second authentication parameters, and communicates an authentication response including one or more details of a first payment mode of the plurality of payment modes to the terminal device based on a match between the first authentication parameter and the second authentication parameter. The transaction is processed based on the authentication response.

A method for on-behalf ATM processing via blockchain includes: receiving, by a receiver of an automated teller machine (ATM), a transaction identifier; receiving, by an input device interfaced with the ATM, a withdrawal amount; identifying, by the ATM, a blockchain transaction in one of a plurality of blocks comprising a blockchain, wherein the blockchain transaction includes at least the transaction identifier and a current balance; and processing, by the ATM, withdrawal of the withdrawal amount based on the current balance, where processing includes dispensing, by a dispenser interfaced with the ATM, currency equivalent to the withdrawal amount if the withdrawal amount is less than or equal to the current balance or displaying, by a display device interfaced with the ATM, a message indicating an insufficient balance if the withdrawal amount is greater than the current balance.

Method and system for facilitating ATM transactions using blockchain

A method for tracking rash driving includes: receiving a plurality of rider embarkation notifications, each including a digital signature and a vehicle identifier; generating a new block for a blockchain, the new block including a block header and a plurality of blockchain data values, each blockchain data value corresponding to a rider embarkation notification and including the respective digital signature; receiving a rash driving notification including the vehicle identifier; transmitting a confirmation request to at least one mobile computing device associated with one of the plurality of rider embarkation notifications; receiving a confirmation message from one of the at least one mobile computing devices; and generating a subsequent block for the blockchain, the subsequent block including a new block header and a new data value, the new data value including an indication of rash driving.

Method and system for real-time driving alerts

A method for preventing account referral fraud includes: receiving a referral request, the request including a referring account identifier; transmitting a digital signature corresponding to the referral request to a processing server; verifying, by the processing server, the digital signature using a public key; identifying a plurality of blockchain data values included in a blockchain using the public key, wherein each data value is related to a blockchain transaction involving a blockchain wallet associated with the public key; generating an authenticity score for the blockchain wallet based on data included in the plurality of blockchain data values; receiving, by the referral server, the authenticity score from the processing server; and processing the referral request based on the authenticity score, wherein processing the referral request includes one of: declining the referral and awarding a referral reward.

Method and system for referral fraud prevention via blockchain

A method for facilitating communications while protecting customer privacy through cryptography and withholding of personally identifiable information includes: storing, in a memory of a processing server, contact data and a reference value associated with a first external computing device; receiving, by a receiver of the processing server, a communication request from a second external computing device, the communication request including at least the reference value and a digital signature; validating, by a processor of the processing server, the digital signature using a communicator public key of a cryptographic key pair; receiving, by the receiver of the processing server, a communication message from the second external computing device; and forwarding, by a transmitter of the processing server, the communication message to the first external computing device using the stored contact data following successful validation of the digital signature.

Method and system for protection of customer PII via cryptographic tokens

The disclosed subject matter includes methods, systems, and networks for authentication based on physical characteristics of a mobile device. A computer-implemented method performed by a payment network includes receiving an image of a part of a mobile device from an image capturing device that communicates with the payment network, wherein the mobile device includes digital card data of a customer. The computer-implemented method may also include comparing a physical condition of the part of the mobile device shown in the received image to the physical condition of the part of the mobile device shown in a stored image. In addition, the computer-implemented method may include authenticating or declining a transaction involving the digital card data based on the comparison of the physical condition of the part of the mobile device in the received image and the stored.

Methods, systems, and networks for authentication based on physical condition of a mobile device

A method and system for disbursing loyalty points is provided. A server receives loyalty points disbursement (LPD) parameters including at least an initial earn rate, a loyalty points budget, and a disbursement period. The server receives an LPD request corresponding to a transaction performed by a user. The server updates the initial earn rate based on at least one of real-time transaction data, predictive transaction data, real-time market disbursement data, and predictive market disbursement data. The server disburses a first set of loyalty points, from the loyalty points budget, to the user based on at least the updated earn rate and a transaction amount of the first transaction.

A method for minimizing inter-bank settlement through incremental updates stored via blockchains includes storing three blockchains: a balance blockchain updated periodically that includes an available balance for a plurality of blockchain wallets, a credit blockchain that includes credits made to a blockchain wallet, and a debit blockchain that includes payments made from the blockchain wallet. Holds are placed on related transaction accounts to enable the blockchain wallets to utilize payments made thereto without the need for a transaction account, where the holds are only updated when necessary based on periodic updates to the balance blockchain, thus minimizing settlements performed by the issuing institutions, thus reducing inter-bank settlements and enabling payees to receive payments from a transaction account without their own.
