Analysis of knowledge based graphical password authentication

摘要

Security itself has unique usability challenges because the requirements of security often standard human-computer-interaction approaches cannot be directly applied. An important usability goal for authentication systems is to support users in selecting better passwords, thus increasing security by expanding the effective password space. We examine the security of knowledge based graphical passwords and their techniques. In our analysis we present the results of an initial users study which present the statically analysis of knowledge technique.
