Patent ID: 8903859

Claim:
A method for generating a fused risk score used to determine a likelihood of fraud from call data, the method comprising: receiving a first leg of call data; generating a first audio component match score for the first leg of the call data based on a comparison of audio data in the first leg with a first voice model in a fraudster database using a first component of a first sub-module; generating a first non-audio component match score for the first leg of the call data based on a comparison of non-audio data in the first leg with a first non-audio data in the fraudster database using a second component of the first sub-module; fusing together the first audio component match score and the first nonaudio component match score using a first fuser component to generate a first fused component match score; determining the fused risk score based on the first fused component matchscore using a risk score fuser module; determining the likelihood of fraud from the fused risk score; fusing together the first sub-module match score and a second sub-module match score using a first fuser sub-module to generate a first module risk score for the first leg of the call data; and receiving a second leg of call data and fusing together the first module risk score and a second module risk score from the second leg of the call data using the risk score fuser module to generate a call fused risk score.
