Abstract: With the advent of internet, various online attacks has been increased and among them the most popular attack is phishing. Phishing is an attempt by an individual or a group to get personal confidential information such as passwords, credit card information from unsuspecting victims for identity theft, financial gain and other fraudulent activities. We are using visual cryptography algorithm for separating privileges. The use of visual cryptography is explored to preserve the privacy of an image CAPTCHA by decomposing the original image CAPTCHA into two shares (known as sheets) that are stored in separate database servers(one with user and one with server 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. of attacks.
