Enhancing Strength Of Graphical Password Using Image Based Textual Password

Abstract

Graphical password is proposed as an alternative solution to text-based alphanumerical passwords. The
password techniques existing currently for authentication have major issues that need to be resolved. The usual
prototype uses selection of the images from the image dataset which are generated at registration phase. The major
challenge here is to remember or recognize the image from the dataset. In order to increase the strength of graphical
passwords a new technique is proposed which generates the password from the selection of combined text and numeric
value contained in image. Thus, in this work an attempt is made further to enhance the strength of graphical passwords
by using image based textual passwords.
