An unforgeable personal identification system for identifying users at remote access control sites. The unforgeable personal identification system generates one-way encrypted versions of physically immutable identification credentials (facial photo, retinal scan, voice and finger prints). These credentials are stored on a portable memory device (credit card size). At a remote access control site, the user presents his portable memory device and the encrypted identification credentials are read. The user then submits physically to inputting of his physical identification characteristics to the remote access control site. Comparison is performed with the credentials obtained from the memory device and with the user\s physical identity to determine whether to allow or deny access at the remote site.
An unforgeable personal identification system for identifying users at remote access control sites, said unforgeable personal identification system comprising: means for generating encrypted physically immutable identification credentials of a user; said means for generating including processor mean
An unforgeable personal identification system for identifying users at remote access control sites, said unforgeable personal identification system comprising: means for generating encrypted physically immutable identification credentials of a user; said means for generating including processor means for processing digital data; text input means connected to said processor means, said text input means for transmitting text data including privilege information to said processor means in digital form; means for encrypting said physically immutable identification credentials and said text data according to a predefined one-way encryption algorithm to produce encrypted identification credentials; portable memory means for storing said encrypted identification credentials; said remote access control site including: means for reading said encrypted identification credentials from said portable memory means; means for directly inputting physically immutable identification of said user; means for comparing said input physically immutable identification of said user with said identification credentials read from said portable memory means, said means for comparing further operating to indicate a successful or an unsuccessful comparison of said directly input identification credentials of said user with said identification credentials of said user from said portable memory means and to allow an access by said user according to said privilege information, if said comparing is successful.
