Notice of Violation of IEEE Publication PrinciplesAuthentication using graphical password to upgrade security & memorability

Today we use Alphanumeric passwords in computer and network to authenticate the user. It is well known that long, alphanumeric passwords are difficult to remember, while shorter ones are easily to attack. Graphical password scheme provides a alternative to this problem. Draw-A-Secret (DAS) is a user drawing implementation on a grid canvas. This paper highlights a graphical password scheme inspired by DAS and serve the the advantages of free drawing positions and large password space. Experiments illustrate the effectiveness of this scheme.
