As conventional textual passwords and common graphical passwords cannot resist the login-recording attacks, many login-recording attacks resistant graphical password schemes based on various techniques have been proposed. Herein, we analyze the security and usability of four weak login-recording attacks resistant graphical password schemes, in which the user can easily and efficiently login the system, and four strong login-recording attacks resistant graphical password schemes, in which the user can login the system in an environment with the threat of serious login-recording attacks. This paper is intended to be used as a reference for e-commerce application developers in designing the authentication mechanism. |
