AN EFFICIENT AND SECURED GRAPHICAL AUTHENTICATION SYSTEM

Abstract

Authentication through the use of passwords usually allow users to access resources in a computer or automated installations. However, remembering such passwords is often a problem for most users due to complex nature of most stong password. As a viable alternative, graphical passwords were introduced to complement the security problems in this method of authentication. Therefore, this papr proposes the concept of a graphical password authentication system using hybrid approach. This approach that allows users to identity a number of images during the registration process and then requested to draw a pattern on each image in a pre-defined order to complete the system approach. This process is represented via a three-stage scheme which consists of the Registration phase, the Login phase and the Authentication phase (RLA). The evaluation was carried out using the comparative study that involves generation of secure graphical password. This methodology is often refered to as Educating Users to Generate Secure Graphical Password Secrets (EUSGPAS). The evaluation involved 200 purposively selected participants who were made to use the new system over six weeks. Experimental results of ESGAS and EUSGPAS indicated a mean success rate of 100%, 97%, 100% and 99%, 96%, 98.9% with a mean completion time of 29.71s and 30.89s respectively. These results indicated the merits of the proposed method over the EUSGPAS approach.
