Arrangement and procedure for determining the authorization of individuals by verifying their fingerprints
First Claim
1. Fingerprint verification apparatus comprising:
- means for storing an arbitrary non-fingerprint related image;
means for reading a fingerprint of an individual whose fingerprint is to be verified;
means for comparing said fingerprint with said arbitrary image and establishing a degree of correlation therebetween;
means for reading data on a data carrier associated with said individual; and
means for comparing data read by said data reading means with said determined degree of correlation for verification purposes.

Abstract
The arrangement uses a portable data carrier in the form of a plastic card, which has several magnetic tracks for containing data. The stored data can consist of the degree of correlation between a fingerprint of the authorized individual and a stored and selected reference signal image and the code number of this reference signal image. Further, use of a so-called characteristic number is possible. A fingerprint detection terminal with a sensor contains a memory in which the selected reference signal image is stored. The sensor compares the actual fingerprint of an individual to be checked with the corresponding reference signal image identified on the plastic card and stored in the fingerprint detection terminal. The thus determined degree of correlation is, in turn, compared to the degree of correlation stored on the plastic card and, as a function of the result of this comparison, an appropriate decision signal is released. The data are written on the plastic card in such a way, that based on the data alone no unambiguous conclusion concerning the identity of the individual is possible.
