Graphical Password Using an Intuitive Approach

Abstract

In this modern age of increasing interconnectivity, information security has come to occupy a pivotal position in recent research works. The vast expanse of Internet and human–computer interaction has created new threats of unauthorized access and data exploitation. Traditional methods of authentication have been text-based password schemes. However, the major drawback with them has been the fact that their strength varies inversely with user convenience. Users generally tend to select passwords that are easier to recall and shorter in length. This, though, makes them vulnerable to cracking attempts. A graphical password is a confirmation framework that works by having the client select pictures, in a particular order. Graphical passwords have inherent advantages over conventional textual password schemes. In this paper, we propose one such graphical password methodology which makes use of the distinct shape, color, and type of image a user chooses, for the purpose of authentication.
