Abstract

A personal identification authenticating system for a client terminal in communication with a server. The server includes a computer and a database. The server performs a service whose uses are limited. The client terminal plays a role of an IC card authorizing device, while the server plays a role of an approval center. The database stores personal information of the service users. The stored personal information on the database includes information related to fingerprints and ID numbers of the service users. A client terminal user impresses one's fingerprint on a fingerprint sensor and puts one's IC card into a card reader. The IC card stores personal information of a card owner. The stored personal information on the IC card includes information related to a fingerprint and an ID number of the card owner. The client terminal includes an authenticator, which provides an authenticating signal if the sensed fingerprint information of the client terminal user matches stored fingerprint information of the card owner. The client terminal transmits the stored personal information of the card owner to the, server upon occurrence of the authenticating signal which transmits an authorizing signal to the client terminal if the transmitted personal information of the card owner matches the stored personal information on the database. Upon receiving the authorizing signal, the client terminal user is authorized to access into the computer of the server.
