个人简介
My work on graphical passwords, Background Draw a Secret (BDAS) [ACM CCS'07] and Shoulder-Surfing Resistant BDAS (SSR-BDAS) [SOUPS'11], were selected by the Royal Society - the UK's national academy of science - for their 2008 Summer Science Exhibition. Since 2011, Microsoft has deployed a version of BDAS in Windows 8 OS and its successors. On the offensive front, in collaboration with Ben Zhu (Microsoft Research), I've developed novel concepts and methods [WWW'13] [CCS'14] for analysing the security of graphical passwords. Our methods for the first time revealed severe security vulnerabilities in a major family of graphical password designs, which was extensively studied in the literature before our work. We also developed the first method for generating high-quality 'graphical honeywords', successfully extending the notion of honeywords from text passwords (proposed by Ariel Juels and Turing Award winner Ron Rivest) to graphical ones.
