Image Shape Based Mutual Authentication to Enhance the Web Security

摘要

Nowadays, there is a drastic increase in the E-Commerce websites, and there are lots of threats and hacking happening in the website. There are numerous security attacks and survival of many phishing websites. In current systems, two-factor authentications, One Time Password (OTP) areused to overcome these issues. In the case of One Time Password, mobile technology is used to send the password to the client for authorization, in some cases mostly hand held mobiles may not be within reach or there may be numerous issues like network traffic and delay in receiving passwords.These problems decrease the ability of authentication. In order to further improve the security performance, here we use more than one image for mutual authentication. The images can be selected from the internet and from the selected images more than one image is chosen for region selectionand recording number of clicks. These features would enhance the security of an account. The performance of the system has been analysed using shoulder surfing, brute force, dictionary, random and reply attack to prove the web security.
