Authentication Schemes for Session Passwords Using Color and Images

Abstract

Authentication is the first and the most important step in information security. It is used to authenticate the user identity. Where user need to memorize their password and remember at login time. Normally user use textual password to provide security, but textual passwords are vulnerable to many cyber-attacks, Such as - dictionary attacks, shoulder surfing etc. Graphical password schemes are used to overcome these problems. A Session password is a new technique based on the graphical password in which we using combination of text, color and images to solve the problem of security. Every time session password can be used to create password for user authentication, by this technique we can overcomes the attacks like shoulder surfing, dictionary attacks. We can use this method for PDAs (Personal Digital Assistants). A multitude of graphical based password scheme which have been proposed as alternative to text based password scheme, motivated by the promise of improved password memorability and thus usability. This paper presents a detailed evaluation of the various Authentication schemes which provides high level of security and provides security to your folder. It consists of three authentication methods like text, picture and colors for providing higher security.
