Abstract: Systems, methods, and apparatuses for providing a customer a central location to manage permissions provided to third-parties and devices to access and use customer information maintained by a financial institution are described. The central location serves as a central portal where a customer of the financial institution can manage all access to account information and personal information stored at the financial institution. Accordingly, the customer does not need to log into each individual third-party system or customer device to manage previously provided access to the customer information or to provision new access to the customer information. A user additionally is able to have user data and/or third-party accounts of the user deleted from devices, applications, and third-party systems via a central portal.

Abstract: Systems, methods, and computer-readable storage media configured to facilitate execution of transactions via a money transfer network are disclosed. During execution of the transactions, tokenized identity information may be utilized when exchanging transaction data between geographically distributed nodes of the money transfer network and the transactions are recorded to a distributed ledger maintained by the nodes. Smart contracts may be utilized to digitally sign transactions at various stages of transaction processing, such as at different stages of regulatory compliance validation and to authenticate the validity of the requested transaction (e.g., prevent double-spends). Utilizing tokenized identity information may reduce the likelihood that personally identifiable information (PII data) is obtained by or inadvertently provided to unauthorized third parties or systems.

Abstract: Systems and methods are provided for leveraging blockchain technology in a swarm learning context, where nodes of a blockchain network that contribute data to training a machine learning model using their own local data can be rewarded. In order to conduct such data monetization in a fair and accurate manner, the systems and methods rely on various phases in which Merkle trees are used and corresponding Merkle roots are registered in a blockchain ledger. Moreover, any claims for a reward are challenged by peer nodes before the reward is distributed.

Abstract: Methods and systems for authenticating a short-range communications HCE (Host Card Emulation) application for mobile communications devices. HCE application data can be transmitted to each registered mobile communications device among a group of mobile communications devices for storage of the HCE application data in a non-volatile memory associated with each registered mobile communications device. The HCE application data include a unique identifier, an expiry date, and an authentication key valid only for a user of each registered mobile communications device. The authentication key can then be diversified by the expiry date and the unique identifier so that the authentication key is only usable for a limited amount of time and the unique identifier is only usable for a single mobile communications device.

Abstract: A system of electronic communication is disclosed. The system may: create a Pre-Authentication Transaction Number (Pre-ATN) by combining a number with a Special Encode Value (SEV), wherein the SEV is a single digit integer value; encrypt the Pre-ATN using a Format Preserving Encryption (FPE) to generate an encrypted Authentication Transaction Number (ATN); and send the encrypted ATN to an access control server (ACS) to use the encrypted ATN to generate a cardholder Authentication Verification Value (CAVV) or an Accountholder Authentication Value (AAV).

Abstract: The invention presents a solution in which blockchain Transactions are created to implement the functionality of a logic gate. The invention may be implemented on the Bitcoin platform or an alternative blockchain platform. The transaction includes a locking script which comprises instructions selected so as to implement the functionality of a logic gate, such as the XOR gate. When the script is executed (because a second transaction is attempting to spend the output associated with the locking script) the inputs will be processed by the conditional instructions to provide an output of TRUE or FALSE. The inputs are pre-processed by one or more computing agents so that they are evaluated to TRUE or FASLE prior to being used as inputs to the script. The second transaction is transmitted to the blockchain network for validation and, if determined to be valid, it will be written to the blockchain. Validation of the second transaction can be interpreted as a TRUE output.
