Implementation of Graphical Password Authentication Technique for Security Using Cued Click Points Algorithm

In today's world, most Internet applications still establish user authentication with a traditional text-based password. Designing a secure as well as user-friendly password-based method has long been on the agenda of security researchers. On the one hand, there are password manager programs that make it easy to create site-specific strong passwords from a single user's password to eliminate the memory burden caused by multiple passwords. We offer different levels of authentication such as Textual Authentication, Image Authentication and Audio Authentication to provide better security for applications. User will select username and password while registering in text step. During registration the user has to enter the registered username and password, if it matches the database then the user can log in to the system. In Image Authentication Model, we take image as input from user at the time of registration and put quid point, qud point is selected part of image which is selected by user. At the time of login the user has to select the image and select the part of the image which he/she wants to include at the time of registration, which is called as Cued Points.
