Abstract: Graphical password is an authentication means alternative to textual password and biometric password. Graphical passwords are classified into two groups: picture based password and user-drawn based password. To pass the authentication, in the picture based graphical password, users have to choose right photos whereas in the user-drawn based graphical password, users have to draw correct pictures. In this paper, we propose a new user-drawn based graphical password. The proposed scheme requires users to create their secret by selecting individual points or by connecting points into curves from a given set of points. Compared to textual password and existing graphical password such as DAS, our proposed password gives larger memorable password space with sufficiently large number of given points.
