چکیده
Authentication is the first line of defense against compromising confidentiality and integrity. People can remember pictures better and for longer periods than alphanumeric passwords. All graphical passwords have two different aspects which are usability and security. Woefully none of these schemes were being able to fulfill both of these aspects at the same time. We analyze the known attack method and categorize them into two kinds Attack by Password Space and Attack by Password Capture. In this paper we summarized the usability and security reported in some user‟s studies of recognition based graphical password schemes. Finally some suggestion were given
