Authentication Using Images and Pattern

Abstract

Secrete code (password) provides the sanctuary mechanism for substantiation and protects user data or unauthorized access of information. Graphical password base hybrid authentication system is a new password scheme. New scheme is alternative to textual password. In that password is created from images and text password. Existing password scheme is easy but the problem in that when user give the small password then it is easy to guess through different attack i.e. dictionary attack and brute force attack. If the text password length is greater, then it is hard to remember and user can write our password in page or in computer file. If the page is damage or that computer file is corrupted then password is loss. Existing system consist only images for password or draw a secret pattern for password, but there was problem of shoulder surfing. Any person is easily seeing the other person password and accesses his secret information. New method of secret code is image password. Individual can easily remember picture as compare to alphanumeric secrete code. In this paper we have proposed a new image password scheme, in that user can give password in combination of images and secrete pattern. The system is a combination of recognition base technique and secrete code (alphanumeric) password, recall base technique and secrete code (alphanumeric) password or recognition base technique and recall base technique. Our system removes the problem of mouse logger and shoulder surfing problem in greater extent. Graphical password is use in PC, smart hand held device, ATM machine.
