Building an optimal document authentication system

Abstract

In this work, a probabilistic approach to assessing the quality of a system for determining the authenticity of documents in the images is considered. The considered system is based on the aggregation of responses of various checks of the security elements of the document. We propose a probabilistic model of the document authentication system and the functional for evaluating the quality of the system. Based on them, we offer an approach for assessing the quality of the separate part and the whole system. Finally, the approach to constructing an optimal function of making a final decision is obtained.
