Concept of Multicriteria Aid of Choice of Threshold Value IN Biometrical Authentication System

This paper is the introduction for further searching of the best solution for choice of threshold value in biometrical authentication system. That is one of the most important problems in a practical point of view. The most suitable solution of that problem can be reached by using different mathematical apparatus. At the beginning we consider mulicriteria approach for solving that problem. And also there is biometrical aspect of the problem mentioned in order to that threshold value. The main concept is to create appropriate apparatus to declare threshold value and all connected restrictions. That point of view allows to present groups of users of different kinds. This paper is the first step for finding the best solution of proposed problems.
