In a multiparty verification system, a prover and a verifier are coupled to rocess respective outputs to provide a system output such as an identification verification. The prover is formed of plural units which share confidential information used to encrypt information carried by the prover. Communication between the prover units is prevented. The first prover unit encrypts the information based on additional information received from the verifier and transfers the encrypted information to the verifier. Subsequently, the verifier obtains from the second prover unit the shared confidential information required to decrypt a subset of the transmitted encrypted information.
