IDENTITY VERIFICATION PROGRAM, IDENTITY VERIFICATION METHOD, USER TERMINAL, AND USER AUTHENTICATION PROGRAM

Abstract:

An identity verification program causes a computer that is a user terminal (100) to execute a processing function for identity verification by a zero knowledge proof. The identity verification program acquires Witness that is information that only a user of the user terminal (100) is allowed to know. Such an identity verification program generates a proof for user authentication by zero knowledge proof based on the acquired Witness. The identity verification program transmits a user authentication request based on the generated proof to a cloud server (200).
