Secure Authentication Using Visual Cryptography


Deepti Chaudhary and Rashmi Welekar                       



Visual Cryptography is a cryptographic technique which allows visual information (text, picture, etc.) to be encrypted in such a way that decryption becomes a mechanical operation that does not require a computer. Visual Cryptography deals with any type of secrets such as printed or pictures, etc. These secrets are delivered into the system in a digital (image) form. The secrets which are in a digital form divided into different parts based on the pixel of the digital secret. These parts are called shares. To visualize the secret, the shares are then overlapped correctly.This paper introduces secure authentication using Visual Cryptography. In any authentication system the major problem is the authenticity of the customer. Due to unavoidable hacking of the database on the internet, it is always difficult to trust the information on the internet. To solve this authentication problem, we are discussing with the two most important topics based on image processing and visual cryptography.
