Method and apparatus for fraud detection
First Claim
1. A fraud detection method for generating a first fraud or fraud attempt probability, within an at least one captured or recorded interaction, the method comprising:
- a scoring step for scoring an at least one voice belonging to an at least one tested speaker in the at least one captured or recorded interaction against an at least one voice print within an at least one entry in a voice print collection, the scoring step generating a probability that the at least one voice in the captured or recorded interaction belongs to an at least one second speaker associated with the at least one voice print, said probability represents the probability that the at least one captured or recorded interaction is fraudulent; and
a reporting step for generating or updating a report comprising details of the at least one captured or recorded interaction if said first fraud or fraud attempt probability exceeds a predetermined threshold.

Abstract
An apparatus and method for detecting a fraud or fraud attempt in a captured interaction. The method comprising a selection step in which interactions suspected as capturing fraud attempts are selected for further analysis, and assigned a first fraud probability, and a fraud detection step in which the voice is scored against one or more voice prints, of the same alleged customer or of known fraudsters. The first fraud or fraud attempt probability is combined with the result of the scoring of the fraud detection step, to generate a total fraud or fraud attempt probability. If the total fraud or fraud attempt probability exceeds a threshold, a notification is issued. The selection, scoring and combination thereof are performed using user-defined rules and thresholds.
