摘要:

Touchscreen mobile devices become essential tools in our daily life. These devices can be used to access various services at anytime/anywhere, and they also store owners’ private and sensitive information. In order to prevent unauthorized access to these devices, user authentication is essential. Traditional password and graphical pattern are 2 popular user authentication methods. However, both of them are subject to shoulder-surfing attacks.

 In this talk, I will present 2 solutions to enhance the user authentication for mobile device touchscreen unlocking. One is Cover-Pad, which provides leakage-resilience for traditional password based user authentication. It breaks the correlation between the underlying password and the interaction information observable to an adversary. Another is TMGuard, which introduces behavioural biometrics into graphical pattern based user authentication. It verifies users' unique touch movement features during the graphical pattern input. Our user studies demonstrate that both solutions can improve the security of traditional password based and graphical pattern based user authentication without compromising their usability.
