Abstract

The security is main concern in each and every application. Graphical authentication provides secure way of authorization. Goal of knowledge specific authentication system is to provide support for user in selecting passwords for greater security. Here we are using 2D coordinates to secure a picture and generate a password. Additionally the pictures in x and y coordinates change randomly and hence it is difficult to find the original picture. Our base paper provides solution against the attacks possible on these approaches “Persuasive cued click points”,” Cued click points ” and “Pass points”. We propose a system which removes the problem of shoulder surfing.

Highlights

For successful authentication, the user must enter a password and provide a pass code generated by the token, Graphical password act as an alternative for textual passwords

The proposed authentication system consists of a sequence of “n” images and the user has to type the coordinates of original image

Summary

INTRODUCTION

The user must enter a password and provide a pass code generated by the token, Graphical password act as an alternative for textual passwords. Graphical authentication is proposed as a user-friendly alternative for password generation and authentication [6] In this approach the user enters the password by typing both the x and y coordinates of the original image. Pass Points-style graphical passwords have been shown to be susceptible to hot-spots, which can be exploited in human-seeded attacks, whereby human-computed data is used to facilitate efficient attacks These attacks require that the attacker collect sufficient “human-computed" data for the target image, which is more costly for systems with multiple images [5]. International Journal of Advanced Research in Computer Science, 9 (2), March-April 2018, 467-469 into a single value with compression algorithm once again In this graphical authentication method, pixel value will be used as authentication key for a password. In Pass Points password a password consists of sequence with 5 to 8 different click points on single image and points are chosen by user[10]
