Where Usability and Security Go Hand-in-Hand: Robust Gesture-Based Authentication for Mobile Systems
September 5, 2019
Our work studied the preprocessing and recognition
methods for gesture passwords. We analyzed 12 gesture recognizers and designed
a superior one, called Garda. Our novel multi-expert recognizer, Garda,
achieved the lowest error rate in both authentication accuracy and imitation attacks. As well as resisted all brute-force attacks. The best combination for recognition is having
all three parameters set as invariant. The optimal combination for authentication
reduces the error rate by 45% compare to the recognition benchmark.
