Abstract
Biometric technologies using biometric information like fingerprints features are in wide use for the secure user authentication in many services including log-in of computer systems, entrance ID and E-commercial security. Nowadays, biometric technologies are ported into small embedded systems like security tokens or smart cards due to the merit of being secure and automatic in comparison with the previous method in user authentication such as using a PIN. In this paper, the security token developed as an embedded system and tile user authentication system implemented and tested using fingerprints information are described. Communications between the security token and tile host are tested and verified with USB. And, execution time and runtime memory on tile security token board was measured and performance improvement was described. In addition, requisites for the transit from the security token to the match-on-card was mentioned.
