Work in progress: A new approach of changeable password for keystroke dynamics authentication system on smart phones

摘要: Most of subscribers use personal identification number (PIN) codes which combined with 6–8 numbers to protect their Subscriber Identity Module (SIM) cards from illegal accesses. To enhance security, many previous studies have employed keystroke dynamics the PIN code, and relative results exhibit that can indeed improve security a code. However, traditional dynamics-based authentication (KDA) system has collect user's firstly then produce unique biometrics. It's inconvenient for users when changing is required, because corresponding KDA systems be retrained. solve above-mentioned drawbacks, this paper proposes novel technique by change anytime, without any extra retraining. Conducted experiment show proposed approach effectively distinguish legitimate impostors even original passwords.
