Abstract:
1. A method for verifying a calling party's identity during a call, comprising: obtaining data concerning the calling party; deriving a voiceprint from a verbal utterance by the calling party during the call; verifying the identity of the calling party based on a comparison of the voiceprint with one or more voiceprint samples stored in association with the data concerning the calling party wherein at least one of the one or more voiceprint samples is associated with a time when the at least one voiceprint sample last compared successfully to a voiceprint of the calling party and wherein the at least one voiceprint sample is removed from storage as a function of the time; if the comparison fails to verify the identity of the calling party, determining the identity of the calling party based on identifying information received during the call; and if the identity of the calling party is determined based on the identifying information, selectively storing the voiceprint in association with the data as a voiceprint sample.
