Prevention of Phishing Attacks with the Help of Anti-Phishing Website using Visual Cryptography (Banking Portal)

For security purposes every application provides user authentication. From a very long time secret data or computer code has been used for giving security to information. In user authentication we have to complete the process of entering username and password. Authentication process has 3 parts Token based, Biometric and Knowledge based authentication. Almost all existing web applications are providing knowledge based authentication including alphanumeric passwords as well as graphical passwords. In today’s changing world when we are having number of networks and personal accounts some secure authentication method is required. In the process of phishing an individual, group tries to thieve personal and con�dential information of the user such as passwords from unsusceptible victims for the purpose of identity theft, �nancial gain and other fraudulent activities causing loss. A new approach has been proposed in this paper called “An Anti- Phishing Framework Based on Visual Cryptography� to solve the problem of phishing. Here an image based authentication using Visual Cryptography (vc) is used. The VC scheme method is explored to preserve the privacy and security of image captcha. It decomposes the original image captcha into two shares that are stored in separate database servers such that the original image captcha can be revealed only when both are simultaneously available. The individual sheet images do not reveal the identity of the original image captcha. Once the original image captcha is revealed to the user it can be used as the password. In the above mentioned approach we provide image based authentication, where password image is generated for every login attempt and it will be downloaded from the registered email of the user which has been used for registration. Every time the image generated is unique.
