A Karnaugh Map Based { 2 , 2 } Visual Cryptography Scheme For Color Images
نویسنده
چکیده
A novel {2,2} visual cryptography scheme for processing color images based on a Karnaugh map design is introduced in this paper. The encryption and decryption functions are executed at the bit levels of the RGB color representation. The proposed scheme affords no pixel expansion and offers perfect reconstruction. Experimental results including in this paper support the main argument that the developed scheme is ideal for transmission of color images over un-trusted, bandwidth limited communication channels.

Identity Based Color Image Cryptography
An Identity based cryptography based on visual cryptography scheme was proposed for protecting color image. A color image to be protected and authentic entities such as account number, password, signature image are given as input. The binary key image is obtained by distributing the digital signature of obtained authentic entities. A secret color image which needs to be communicated is decompos...
متن کاملProgressive Color Visual Cryptography ( Final version of the manuscript ID : JEI 03158 )
Visual cryptography is a powerful technique which combines the notions of perfect ciphers and secret sharing in cryptography with that of raster graphics. A binary image can be divided into shares which can be stacked together to approximately recover the original image. Unfortunately, it has not been used much primarily because the decryption process entails a severe degradation in image quali...
متن کاملThreshold Visual Cryptography Scheme for Color Images with No Pixel Expansion
Since the introduction of threshold visual cryptography by Naor and Shamir, there have been many other schemes proposed; some of them support color images with a limited number of color levels while a few others achieve the property of no pixel expansion. However, it is unknown if there is a scheme which can satisfy all the following five commonly desired properties: (1) supporting images of ar...
متن کاملOn the Analysis and Generalization of Extended Visual Cryptography Schemes
An Extended Visual Cryptography Scheme (EVCS) was proposed by Ateniese et al. [3] to protect a binary secret image with meaningful (innocent-looking) shares. This is implemented by concatenating an extended matrix to each basis matrix. The minimum size of the extended matrix was obtained from a hypergraph coloring model and the scheme was designed for binary images only [3]. In this paper, we g...
متن کاملA Review on Visual Cryptography Schemes for Gray Scale and Color Images
Visual cryptography is a technique which combination of perfect ciphers and secret sharing in cryptography. A binary image can be divided into shares which can be stacked together to approximately recover the original image. Unfortunately, it has not been used much primarily because the decryption process entails a severe degradation in image quality in terms of loss of resolution and contrast....
