A Novel Anti Phishing Framework Based On Visual Cryptography

Abstract: Phishing is one of the attacks that became popular recently. It is an identity theft attempt in order to obtain confidential and private information of individuals or companies for monetary or other gains. In the recent part there were many reports on phishing attack in many financial domains including banking. It has become a serious threat to enterprises that deal with financial transactions. If these threats are not addressed thoroughly, people can’t trust online transactions that involve due authentication through credentials. Many solutions came to solve this kind of identity theft. Recently James and Philip proposed a new approach based on visual cryptography to address the issue of phishing. This will automatically preserve the privacy of captcha. It achieves this by dividing the original image into two shares which are to be stored in different databases. The decryption is possible only when adversaries can provide both shared at a time. The individual shares can’t reveal the original captcha. In this paper, we implement the visual cryptography using C# programming language for building an anti-phishing framework. The experimental results revealed that the proposed application is secure and can prevent phishing attacks.
