Abstract: Systems, methods, articles of manufacture, and computer-readable media for secure authentication based on identity data stored in a contactless card associated with an account. An application may receive an indication specifying to perform an operation. The application may receive encrypted data from the card, the encrypted data based on a cryptographic algorithm, a customer identifier, and a private key. The application may receive an indication that the authentication server verified the encrypted data based on the private key for the card. The application may determine a type of data required to authorize the operation. The application may receive data comprising passport data or driver license data from the card. The application may determine that the data satisfies a rule for authorizing the operation and authorize performance of the operation based on the authentication server verifying the encrypted data and the data satisfying the at least one rule.

Abstract: Systems and methods for providing risk determination in a crypto currency transaction include receiving, through a network via a broadcast by a first payer device, a first crypto currency transaction that includes a first payee public address. A first request for a determination of risk associated with the first crypto currency transaction is then identified in the first crypto currency transaction, with the first request including risk criteria. A first payee involved in the first crypto currency transaction is then identified using the first payee public address, and first payee risk information is accessed via at least one external risk information database based on the identification of the first payee. If it is determined that the first payee risk information satisfies the at least one risk criteria in the first request, the first crypto currency transaction is provided for addition to a block in a crypto currency public ledger.

Abstract: A computer system, computer program product, and method includes detecting a request for sensitive information to be input by a user, determining that a network is a non-secure network, disabling a sensitive user information input function to prevent the user from entering sensitive information over the unsecure network, generating a unique identifier to be displayed on the computer, wherein the user scans the unique identifier with a mobile device to initiate an automatic transaction over a secure network between the mobile device and the computing system, validating the user operating the mobile device and completing the automatic transaction over the secure network with the mobile device rather than over the unsecure network with the computer.

Abstract: A dispute resolution cryptocurrency sidechain system includes a system provider that determines that a transaction amount for a transaction has been received at a first public ledger address on a public ledger from a second public ledger address and, in response, allocates a sidechain address on a dispute resolution sidechain ledger. The system provider then sends, through a network to a payer and a payee involved in the transaction, the sidechain address, and monitors the sidechain address for dispute communications. Based on detecting a first dispute communication that is received at the sidechain address and that is signed using a private key that identifies the payer, the system provider device causes a portion of the transaction amount that was received at the first public ledger address to be sent to the second public ledger address.

Abstract: An Internet of Thing (IoT) device includes a transceiver coupled to a processor. Blockchain smart contracts can be used with the device to facilitate secure operation.
