AN EFFICIENT ANTI PHISHING FRAMEWORK BASED ON DYNAMIC CAPTCHA

Web security has become a serious and challenging issue due to the growth of Internet, due to this drastic growth Cyber-attacks has been increasing day by day. Phishing (attempt to obtain sensitive information such as user names, passwords, and credit card details from unsuspecting victims for identity theft, financial gain and other fraudulent activities) is one of the most popular attack. Hackers design fake websites which appear very identical to the original ones are being hosted to achieve this. In this paper a new approach called “Anti-phishing framework based on visual cryptography “is introduced to solve phishing problems. Using Visual Cryptography, we will be able to use image for authentication. Visual cryptography (VC) schemes hide the secret image into two or more images called shares. Here the shares are shared with the user and database. The secret image will be recovered simply by stacking the shares together without any complex computation. The original image captcha can be revealed without any complex computation only when both shares are simultaneously available; the individual sheet images do not reveal the original image captcha. Once the original image captcha is revealed to the user that can be used as the password. Using this method the website cross verifies its identity and proves that it is a genuine website before the end users.
