The Proposed Algorithm: Image Security Technique in Visual Cryptography: (IST-VC)
نویسنده
چکیده
The binary patterns of the shares, however, have no visual meaning and hinder the objectives of visual cryptography. By improving the intensity transformation in Myodo’s method, authors have proposed a method to generate high quality share images with high speed from which a secret image can be reconstructed with apparently higher quality than myodo’s method. In this paper, we review the method and evaluate its performance Based on the blue-noise dithering principles, the proposed method utilizes the void and cluster algorithm to encode a secret binary image into halftone images carrying significant visual information.

Enhancement of Security in Visual Cryptography System using Genetic Algorithm
Visual Cryptography (VC) is a special type of encryption technique where an image or document is encrypted by breaking it down into shares. These shares are then printed on transparencies. Decryption is done by superimposing the shares. Thus one can visually decode the secret image without computation. However, this property makes VC insecure as a third party can easily retrieve the secret info...

Visual Cryptography (VC) is a powerful technique that combines the notions of perfect ciphers and secret sharing in cryptography with that of raster graphics. A binary image can be divided into shares that are able to be stacked together so as to approximately recover the original image. VC is a unique technique in the sense that the encrypted message can be decrypted directly by the Human Visu...

Visual cryptography (VC) is a powerful encryption technique which combines perfect secrecy and secret sharing in cryptography with respect to images. VC takes a binary image (the secret) and divides it into two or more pieces known as shares (transparencies). When the shares are superimposed, the secret can be recovered. One of the distinguishing features of VC is that it needs no computational...
