SYSTEM AND METHOD FOR TELEPHONIC USER AUTHENTICATION

摘要

A telephonic authentication system (11), method and program product. An authentication system is provided for authenticating a user of a telephonic device that includes a setup system (12) for capturing and storing an authentic user speech pattern sample (37), a comparison system (18) that compares the authentic user speech pattern sample (37) with an inputted speech pattern sample (27) and generates a comparison result (32); and a control system (26) for controlling access to the telephonic device. The control system (26) analyzes the comparison result (32) for an initial inputted speech pattern sample (27) received when a telephone call is initiated and periodically analyzes comparison results for ongoing inputted speech pattern samples (27) received during the telephone call.
