GRAPHICAL PASSWORD AUTHENTICATION

Abstract

Authentication is performed using passwords that are alphanumeric in nature. However, users find it
difficult in remembering a password that is long and needs to be recalled again and again while implementing it.
Instead, they create short, simple, and insecure passwords that make the user’s data vulnerable to outside
attacks. Graphical passwords provide a way out of this dilemma by making passwords more remember able and
easier for people to use as a password and, therefore, makes it more secure. Using a graphical password, users
clicks on images rather than typing text passwords which contains alphanumeric characters. A new and more
secure graphical password system has been developed which uses image Pattern. The image segmentation
system presents the user with an image upon which the user selects a number of grids on this image; when
entered in a proper sequence these points authenticate the user. The findings showed alphanumeric passwords
and graphical passwords both worked in similar time but the graphical passwords were easier to recall and
remember. Thus, Graphical passwords were found to be hard to crack as they are newly implemented and not
many algorithms have been devised to break through them
