Data security for Image Shares by 2- Level Authentication in Visual Cryptography
Dinesh Babu T,  Sujatha G.
In today’s world Information security is one of the most important solutions in the computing environment. Cryptography and Steganography are the most widely used techniques to overcome threats to data. By using this cryptography scheme we can save the images or text in database in the form of shares. The secret images can be restored by stacking operation. This property makes cryptography useful especially for the low computation load requirement. A secret message/image transmission will be done through (2, 2) visual cryptographic shares which are transmitted so that a potential eavesdropper won’t be able to know the data that is transmitted or stored. This paper examines the need of developing a methodology which would help the user to represent the resultant message/image in the same size as the original secret image. Also, this paper puts forward a tool which would help the user with a 2 level authentication by password protection.
