Image Password Based Security System

Abstract

In today''s world, hacking is starting to become a major issue and this is the reason that user cannot easily trust the information on the internet. To solve the problem of authenticity, we are proposing an algorithm based on Visual Cryptography and watermarking and this algorithm is applicable for any Login authentication system. This Research proposes a technique of hiding username and password into QR-code after using VCS dividing it into 2 shares or sub images where one of the shares is stored in the database and the other is watermark with reCAPTCHA or User define image and kept by the customer. During all of his transaction the Customer has to present his watermark image. So it will extract share is stacked with database share to get the original QR- image. Once again Decoding is used to extract the secret username and password from the QR- image. Compare it with the original, if both are same user authenticity may be granted and if both are not same, one can decide that the share produced by user is fake and can be rejected.
