OTP is first security medium for stability strengthening of electron financial transaction. In this paper, we propose the method of one time password key generation of OTP using changed location and angle of fingerprint features. Fingerprint is powerful personal authentication factors, and it can create variable password key for one time using information of fingerprint features.
