摘要：In Digital environment authentication plays a major role. For authentication purpose the graphical based technique is used. The purpose of this paper is increasing the security space and avoiding the weakness of conventional password. The most common computer authentication method is to use alphanumeric user name and passwords. User often creates passwords that are memorable which is easy for attackers to guess, but strong system assigned passwords are difficult for users to remember. So researchers of modern days have gone for alternative methods where in graphical picture are used as a password. By using graphical password scheme shoulder surfing attack, masquerading and eavesdropping can be minimized. In this paper, we have changed the way of clicking on the images and to make the password more secure Advanced Encryption Standard (AES) technique is used so that authentication can become more secure and password can be generated, authenticated & protected easily. This paper presents the idea of new graphical idea for authentication. This system can be used for any online/offline system.
