Risk profiler in automated human authentication

Abstract

Risk profiler in this paper is understood as the tool for risk assessment in automated human authentication systems. Authentication of a biometric enable e-passport/ID and the holder of this document (traveler) are the most important functions of such systems. Risks in this procedure are related to both technical and human factors. We developed a profiler tool which can measure the system performance at an arbitrary state of the authentication process. The tool is based on modeling modules, and each is represented by a Belief network and interfacing between the modules. A collection of small modules with reasonably chosen parameters is given as an example, and some examples demonstrating how the modules can be used for inference is also given.
