Claim:
A method comprising: comparing, by a computer-based system 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, at least a portion of a caller voice print with said known voice prints to determine when said caller voice print matches any of said unauthorized known voice prints; identifying, by said computer-based system, 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 first transaction requested by said unauthorized caller; receiving, by said computer-based system, a second communication from said unauthorized caller during a second call; producing, by said computer-based system, a second voice print based on said second communication; matching, by said computer-based system, said second voice print to one of said unauthorized known voice prints; and, denying, by said computer-based system, a second transaction associated with said unauthorized caller.
