Claim:
A computer system for conducting a multi-party electronic transaction, comprising: circuitry for initiating a multi-party transaction with a party at a client computer by sending a request to a transaction management server; circuitry, responsive to a policy defined for the transaction, for contacting at least one other client computer associated with at least one other party to the transaction and requesting the parties to provide biometrics signals; a challenge generator for generating a challenge to all parties to the transaction; circuitry for receiving the challenge at the client computers and for combining, at each client computer, provided biometrics signals with challenge response data; and circuitry for separating the challenge response data from the biometrics signals at the transaction management server, for verifying temporal synchronicity and persistence of biometrics signals acquisition between the multiple participating parties as specified by the policy and, if the verification is successful, for certifying the authenticity of the parties to the multi-party electronic transaction requested by the initiating party.
