Visual Cryptography Using Color Images
Information security has become a major issue as information technology is ruling the world. Cryptography using mathematical techniques is providing information security but requires complex algorithms, intensive mathematical computations and efficient computational resources. To avoid such intensive and complex algorithms a new scheme known as Visual cryptography (VC) was introduced by Naor an...
متن کاملContrast Enhancement in Color Extended Visual Cryptography
Visual cryptography is a secret sharing technique mainly used for image sharing. In the case of extended visual cryptography we use meaningful shares to hide image. Contrast loss in decrypted image is a major problem. Here we use Additional basis matrix and perfect white pixel reconstruction to improve the contrast in color extended visual cryptography. Keywords— Visual Cryptography (VC), Halft...
متن کاملA Secure Visual Cryptography for Color Images
-A visual cryptography scheme is a secret sharing scheme to encode a secret image SI in such a way that any qualified subset of participants can ―visually‖ recover the secret image, while forbidden subsets have no information on SI. A ―visual‖ recovery consists of xeroxing the shares, which are shadow images, onto transparencies and stacking them one on the top of the others. The participants i...
متن کاملExtended Visual Cryptography for Color Shares using Random Number Generators
Visual cryptography is a special image encryption technique. It is different from traditional cryptography, because it does not need complex computation to decrypt. The benefit of the visual secret sharing scheme is in its decryption process where without any complex cryptographic computation encrypted data is decrypted using Human Visual System (HVS). But the encryption technique proposed here...
متن کاملEfficient Techniques for Multimedia Information Hiding using Color Visual Cryptography
In this paper, a novel approach is presented for multimedia information hiding using visual cryptography. The approach combines both the steganographic and cryptographic effect to improve the quality of security and to increase the payload. Both are important parameters in information hiding. The proposed techniques provide three levels of security without reducing the payload and the image qua...
