The most common computer authentication method is to use alphanumeric usernames and passwords. This method has been shown to have significant drawbacks. For example, users tend to pick passwords that can be easily guessed. On the other hand, if a password is hard to guess, then it is often hard to remember. To address this problem, some researchers have developed authentication methods that use pictures as passwords. In this paper, the authors conduct comprehensive analysis of the existing image based password techniques.
