IC card with individual authentication function
First Claim
1. An IC card with an individual authentication function, comprising:
- an IC card main body;
memory means for storing reference finger characteristic data of a card owner;
pressure sensing means, provided on one surface of the IC card main body, for measuring an applied finger pressure as measured finger characteristic data;
collating means for collating the measured finger characteristic data with the reference finger characteristic data; and
control means for permitting use of the IC card on the basis of a collation result of the collating means.

Abstract
A pressure sensor for inputting finger characteristic data and an authenticity sensor for detecting whether a finger is authentic are arranged on the surface of an IC card. A finger can be placed on the pressure sensor and the authenticity sensor at the same time. Finger characteristic data is input by the pressure sensor. A controller calculates a sum signal from the input finger characteristic data, and collates the calculated sum signal with a reference sum signal of an owner of the card stored in a dictionary memory. An authenticity detecting circuit inputs data from the authenticity sensor, and detects whether a finger is authentic. If the finger is authentic and if a coincidence is determined between the calculated and reference sum signals, the use of the IC card is permitted.
