Text based Graphical Password System to Enhance Security

Abstract

A graphical password is a type of authentication that requires the user to choose from a set of images in a certain order. For most people, remembering a graphical password is easier than remembering a text-based password. Passwords with graphics may be more difficult to remember. offer better security than text-based passwords. Humans can remember pictures much better than the text. To create passwords more memorable and less vulnerable to security attacks.  A text based movable frame graphical password system is proposed. The system includes both the Graphical and Text- based images interface for identification.  It displays a grid which is either graphical images, or alphabets or multiple/mixed alphabets. Traditional text- based password schemes are subjected to dictionary attacks. Graphic password systems, which use graphics instead of words as a password, are a promising alternative to text-based recognition schemes. These are again affected due to shoulder surfing and less effective due to large dictionary space. providing a solution based on text-based graphical password techniques. Our research has a main objective: To enhance the security. The graphical password system with multiple alphabet images is more recognizable. It has less cognitive load on user as compared to image based graphical password schemes.
