ABSTRACT:
Typical image parameters of the image of a person to be identified are determined as reproduced on or applied to the identification medium and stored in memory; then, the paper authenticity is checked in a suitable apparatus which redetermines the image parameters on the paper and compares such redetermined parameters with the previously stored ones, supplying a signal of positive or negative check at comparison completion. In addition, a code corresponding to the image is reproduced on or applied to the same identification medium and is also checked for authenticity and serves as a double check of the legitimate bearer of the medium.
