Abstract
The present invention relates to the field of identity authentication. Provided are a method, device, and system for identity authentication, solving the technical problem that existing identity authentication technologies are incapable of protecting personal privacy, and that authentication technologies comprising personal privacy must provide a traceability feature. The method for identity authentication mainly comprises: a first authenticator transmitting to a second authenticator a first identity authentication message; the second authenticator transmitting to an authentication server a second identity authentication message; the authentication server verifying the validity of a secure domain where the second authenticator is at on the basis of the second identity authentication message; the authentication server returning to the second authenticator a third identity authentication message; when the third identity authentication message is received by the second authenticator, same transmitting to the first authenticator a fourth identity authentication message.
