Graphical Authentication System Using Image Panels

Abstract

The use of alphanumeric usernames and passwords is the most widely used technique for authentication. It is found that this technique has serious drawbacks. For instance, users frequently select passwords that are simple to remember. On the other hand, it may be challenging to recollect a complicated password. The creation of an OTP is another option, but it can take some time and comes with a risk (losing it in the allotted time). These existing methodologies have some disadvantages. A graphical authentication is the best to remember and hard to guess. So, a graphical authentication technique is proposed to address the problems of low security, shoulder surfing, dictionary and brute force attacks. In this methodology, the user must register by providing the required information and by selecting a panel from 3-5 images. This methodology is tested using entropy and proved that this approach is efficient than the existing methods..
