A Critique of the Authentication Session at CHI 2011


CHI 2011 included a session regarding the authentication of users of computer systems, and this paper offers a critique of three selected papers from this session. For each paper, a summary of the paper is presented, a critique is offered and questions for the authors are also considered. The three selected papers are based on the MARASIM authentication system, the use of implicit memory in password recovery and the necessity of user-friendly CAPTCHA.
