Abstract

Systems and methods are provided for fraud detection in payment processing. In an illustrative implementation, a fraud detection platform comprises a fraud detection engine and at least one instruction set. In the illustrative implementation, the instruction set comprises one or more instructions to instruct the fraud detection engine to process m-commerce payment transactions according to a selected one or more fraud detection paradigms. In an illustrative operation, the fraud detection engine generates a fraud score that can be calculated by processing payment transactions among a group of users of a payments network based upon the network of other users with whom the user transacts via electronic payments or communications. Further, in the illustrative operation, the fraud scoring processing makes use of a transaction authentication score which can be derived from the strength of the network connection (or, the degree of separation) between two users who are party to the transaction.
