PC User Authentication using Hand Gesture Recognition and Challenge-Response
Sangmin Shin, Minsoo Kim · JOURNAL OF ADVANCED INFORMATION TECHNOLOGY AND CONVERGENCE · 2018
The current PC user authentication uses character password based on user’s knowledge. However, this can easily be exploited by password cracking or key-logging programs. In addition, the use of a difficult password and the periodic change of the password make it easy for the user to mistake exposing the password around the PC because it is difficult for the user to remember the password. In order to overcome this, we propose user gesture recognition and challenge-response authentication. We apply user’s hand gesture instead of character password. In the challenge-response method, authentication is performed in the form of responding to a quiz, rather than using the same password every time. To apply the hand gesture to challenge-response authentication, the gesture is recognized and symbolized to be used in the quiz response. So we show that this method can be applied to PC user authentication.
