REMOTE AUTHENTICATION BASED ON EXCHANGING SIGNALS REPRESENTING BIOMETRICS INFORMATION

摘要

A method, an apparatus, and a computer program product for remote authenticationare disclosed. The methods are based on exchanging of signals representing remoteparty's biometrics information (such as acoustic waveforms) and have application insecure telephony or video-conferencing communications over open networks. Theapparatus includes a speech encoding/decoding module (632), a control module (636),an encryption/decryption module (640), a key generator (650), a Diffie Hellman keyexchange system (660), a timer module (670) for measuring time between achallenged statement and a corresponding response statement, an input/output (I/O)module (680) for transmitting and receiving data via a communications channel 610.
