Title:
APPARATUS AND METHOD FOR EXAMINING QUALIFICATION OF PERSON WHO USES DATA CARRIER BY CHECKING FINGER PRINT
Document Type and Number:
Japanese Patent JPS62278685
Kind Code:
A
Abstract:
The arrangement uses a portable data carrier in the form of a plastic card which has several magnetic tracks for receiving data. The data stored may consist of the degree of correlation between a fingerprint of the authorised person and a stored and selected reference signal image and the code number of this reference signal image. Furthermore, it is also possible to use a so-called characteristic number. A fingerprint recording terminal with a sensor contains a memory, in which the selected reference signal images are stored. The sensor compares the current fingerprint of a person to be checked with the corresponding reference signal image characterised on the plastic card and stored in the fingerprint recording terminal. The reference degree of correlation thus determined is then compared with the degree of correlation stored on the plastic card and, in dependence on the degree of correlation, a corresponding decision signal is triggered. In this case, the data are registered on the plastic card in such a way that no unambiguous conclusion concerning the identity of the person can be drawn from the data alone.
