Patent ID: 7299177

Claim:
A method for facilitating an analysis of a voice of a caller to determine a potential match with known voice prints which include authorized known voice prints and unauthorized known voice prints, comprising: receiving a communication from said caller during a call; recording an electronic representation of at least a portion of said voice of said caller and a voice of an agent receiving said call; segmenting at least a portion of said electronic representation such that said voice of said caller can be separated from said voice of said agent to produce a caller voice print; comparing at least a portion of said caller voice print with said known voice prints to determine when said caller voice print matches any of said unauthorized known voice prints; identifying said caller as an unauthorized caller when said caller voice print matches any of said unauthorized known voice prints stored in an unauthorized voice print database and denying a transaction requested by said unauthorized caller; receiving a second communication from said unauthorized caller during a second call; producing a second voice print based on said second communication; matching said second voice print to one of said unauthorized known voice prints; and, denying a transaction associated with said unauthorized caller.
