SYSTEMS, METHODS, AND MEDIA FOR DETERMINING FRAUD PATTERNS AND CREATING FRAUD BEHAVIORAL MODELS

摘要

Systems, methods, and media for analyzing fraud patterns and creating fraud behavioral models are provided herein. In some embodiments, methods for analyzing call data associated with fraudsters may include executing instructions stored in memory to compare the call data to a corpus of fraud data to determine one or more unique fraudsters associated with the call data, associate the call data with one or more unique fraudsters based upon the comparison, generate one or more voiceprints for each of the one or more identified unique fraudsters from the call data, and store the one or more voiceprints in a database.

主权项

1. A method for analyzing call data associated with fraudsters, the method comprising:
executing instructions stored in memory, the instructions to be executed by a processor, the instructions being configured to: responsive to receiving first call data associated with fraudsters:
(a) generate a voiceprint for each fraudster in the first call data such that a first plurality of voiceprints are generated;(b) retrieve from a blacklist database a second plurality of voiceprints;(c) compare each voiceprint of the first plurality of voiceprints with each voiceprint of the second plurality of voiceprints to generate a plurality of relative comparison scores, wherein the comparing is performed using a matrix arranged such that the first plurality of voiceprints are disposed on a first axis of the matrix, the second plurality of voiceprints are disposed on a second axis of the matrix, and such that cells of the matrix include a relative comparison score for each voiceprint pair, wherein relative comparison scores are numerical values that indicate a degree of similarity between two voiceprints; and(d) group together voiceprint pairs having relative comparison scores above or below a predetermined threshold values; generate a master voiceprint for the group; and generate the master voiceprint in the blacklist database.
