Chair Professor Chin-Chen Chang. National Tsing Hua University National Chung Cheng University Feng.

This project was developed to insert a message into an image and the image was divided into a number of shares which when overlapped formed the actual. process made use of an encryption technique that is based on pixel shuffling and a secret key generated from the image. Keywords—visual cryptography. phishing framework based on visual cryptography" to solve the problem of phishing. Here an image based authentication using Visual Cryptography (vc) is used.

## combines the use of both steganography and visual cryptography is suggested. There are Novel Visual Cryptographic and Steganographic Methods, Forensic .

Visual cryptography is a cryptographic technique which allows visual information (pictures, text, etc.) to be encrypted in such a way that the decrypted information. Halftone Visual Cryptography. IEEE TRANSACTIONS ON IMAGE PROCESSING, VOL. 15, NO. 8, AUGUST , pp. Zhi Zhou, Gonzalo R. Arce. In Visual Cryptography, several images, called “shadow images”, that separately contain no information, are overlapped to reveal a shared secret message.

Abstract:Data safety is needs of research for avoid the hacking. There are many research related to security reason is internet security, cryptography etc. Right.

increasing customer confidence and preventing identity theft. The method uses combined application of steganography and visual cryptography for this purpose.

Pixel expansion is an important parameter for Visual Cryptography Schemes The shares of visual cryptography are printed on transparencies which need to. There are diverse visual cryptography schemes developed based on Visual cryptography, random grid, pixel expansion, extended visual cryptography,XOR. A visual cryptography scheme (VCS) is a kind of secret image sharing scheme which call it the Embedded Extended Visual Cryptography Scheme (EEVCS).
