  • Patent number: 9503571
    Abstract: 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.

  • Patent number: 8903859
    Abstract: Systems, methods, and media for generating fused risk scores for determining fraud in call data are provided herein. Some exemplary methods include generating a fused risk score used to determine fraud from call data by generating a fused risk score for a leg of call data, via a fuser module of an analysis system, the fused risk score being generated by fusing together two or more uniquely calculated fraud risk scores, each of the uniquely calculated fraud risk scores being generated by a sub-module of the analysis system; and storing the fused risk score in a storage device that is communicatively couplable with the fuser module.

  • Patent number: 5502645
    Abstract: High level synthesis of datapaths has traditionally concentrated on synthesizing a specific implementation for a given computational problem. Methods to compose a reconfigurable BISR (built-in-self-repair) implementation with a minimum amount of area overhead are disclosed. Previously the BISR scope has been restricted to the substitution of operation modules with only those of the same type. Novel resource allocation, assignment and scheduling and transformation methods, primarily for ASIC designs, are described. These methods are based on the exploration of the design solution space accomplished by use of high level synthesis processes to find designs where resources of several different types can be backed up with the same unit.
