Graphical password (i.e., image based authentication) is considered as a promising alternative to traditional textual password for mobile devices, to achieve better tradeoff between usability and security. However, previous proposals of graphical password have the limitation of limited entropy. In this paper, we propose a new scheme incorporating user face based authentication into the association-based graphical password solution we proposed before, aiming at achieving higher security without compromising user-friendliness for mobile application scenarios. System performance analysis and comparisons with other schemes are presented to validate our scheme.
