Abstract
Security of ubiquitous computing systems is becoming more important along with extensive spread of the Internet applications. In this paper, we propose a key generation method for one-time password of Mobile-OTP systems by employing changed location and angle of fingerprint features. Fingerprint, as one powerful personal authentication tool, can create variable password keys for one-time use cyclic key permutation (CKP) of fingerprint features. Based on a set of simulations for the proposed random password key generation method, we evaluate the efficiency and strength of proposed modification for Mobile-OTP systems and describe application scenarios to support secure service.
