An Attempt to Memorize Strong Passwords while Playing Games

There could be two approaches for combining security with entertainment, (i) an entertainment factor is embedded in security technology and (ii) a security factor is embedded in entertainment technology. Since all previous studies were focused on approach (i), we examined approach (ii). As the first attempt, this paper tried to embed a password enhancement factor into games. We designed a password enhancement scheme which enables users to naturally memorize strong passwords while playing games. We also discuss the effectiveness of our scheme.
