%X There were lots of defects for logging characters about legal users in many Identity authentication systems. By the means of additional time-stamp, this system realized a kind of stronger audited mechanism, in which logging time was undeniable to customers. Authentication measure made use of the DSA digital-signature to guarantee the safety of this system on the law. The design model to this system realized the separation of client software and password key in physical location, thus it was strengthen about security, practicability and expansibility.
