System and Method For Identity Chaining

Abstract: An identity chaining fraud detection method that allows each current transaction to be linked to other transactions through commonly shared identities. Over a period of time the links create a chain of associated transactions which can be analyzed to determine if identity variances occur, which indicates that fraud is detected. Additionally, if a specific identity is detected as being fraudulent, that identity can be tagged as fraudulent and can be referenced by a plurality of other merchant transaction chains to determine fraud.

Hybrid approach to approximate string matching using machine learning

Abstract: Systems, apparatuses, and methods are provided for identifying a corresponding string stored in memory based on an incomplete input string A system can analyze and produce phonetic and distance metrics for a plurality of strings stored in memory by comparing the plurality of strings to an incomplete input string These similarity metrics can be used as the input to a machine learning model, which can quickly and accurately provide a classification This classification can be used to identify a string stored in memory that corresponds to the incomplete input string

Cryptographic label for attachment to a communication card

Abstract: A cryptographic label is provided for enabling a mobile communications device to perform secure communications. The label comprises a flexible printed circuit having a first set of electrical contacts disposed on a top side of the circuit for interfacing to a mobile communications device, a second set of electrical contacts disposed on a bottom side of the circuit for interfacing to a communication card, and a hardware security module disposed in the circuit and coupled to the first and second sets of electrical contacts. The label is characterised in that it further includes a skirt attached to the flexible printed circuit, the skirt having an adhesive portion on at least a bottom side thereof which, in use, bonds to a communication card to attach the label to the communication card. The skirt is capable of having printed indicia provided on a top side thereof.

Systems and methods for creating multiple records based on an ordered smart contract

Abstract: A method for creating a smart contract detailing an ordered set of events is disclosed. A smart contract can include information about multiple events and responses for each event. The events and response can be arranged in a predefined order. The responses can include adding new records to a blockchain.

System and method including chip-based device processing for transaction

Abstract: Present embodiments are directed to a server computer. The server computer establishes a first channel of communication to receive payment device data in a first format (e.g., chip type) and establishes a second channel to receive the payment device data in a second format (e.g., legacy type). The server computer receives an authorization request message in the second format from a merchant and generates a new authorization request message in the first format. The server computer then forwards the new authorization request to the issuer for approval.
