PPS

Pass Pattern System(PPS) is a Dynamic-Password system and is based on the premise that humans are good at identifying, remembering and recollecting graphical patterns than text patterns. Unlike many User-Authentication systems, in Pass Pattern System (PPS) the user will prove that he knows the secret rather than telling the secret.
User will be provided a matrix, from which he can select the sequence as his password, instead of the word or phrase as his password!
The core idea of PassPattern system is that,
Instead of remembering a sequence of characters as the secret, users have to remember a shape as the secret.
