Authentication system by fingerprint
First Claim
1. A biometric authentication system comprising:
- a mobile storage device with a computing function having a tamper-resistance; and
a reader/writer having a tamper-resistance for reading/writing information from/into said mobile storage device, wherein said reader/writer includes;
a biological information input device for inputting biological information, preprocessing the biological information inputted by said biological information input device, and transmitting intermediate information thus preprocessed to said mobile storage device, and wherein said mobile storage device includes a template of biological information and a secret key to be used for electronic authentication;
compares said intermediate information with said template; and
makes said secret key available upon a match after comparing.

Abstract
A fingerprint identification system comprising: an IC card having a tamper-resistance; and a reader/writer having a tamper-resistance for reading/writing information from/into the IC card. In the reader/writer, a fingerprint image, as read by a fingerprint input unit, is preprocessed in a preprocessing unit, and extracted intermediate information is transmitted to the IC card. This IC card compares the intermediate information with the fingerprint information, and makes authentication information usable for an electronic authentication upon matching. By this electronic authentication with applications, the fingerprint identification system, which has a high level of safety and can reduce the cost is provided.
