Visual Cryptography Based on an Interferometric Encryption Technique
Sang-Su Lee et al. 373 This paper presents a new method for a visual cryptography scheme that uses phase masks and an interferometer. To encrypt a binary image, we divided it into an arbitrary number of slides and encrypted them using an XOR process with a random key or keys. The phase mask for each encrypted image was fabricated under the proposed phase-assignment rule. For decryption, phase m...
متن کاملA Watermarking Technique based on Visual Cryptography
With the explosive growth of internet technology robust methods are being developed to protect the proprietary rights of the multimedia. This paper considers the problem of embedding a binary watermark in a gray-level image using the concept of Visual Cryptography (VC). This paper proposes a watermarking scheme which offers better security than Hwang’s method, so that, attackers will not be abl...
متن کاملAn information hiding technique based on visual cryptography
Visual Cryptography was first proposed by Moni Naor and Adi Shamir in Eurocrypt’94. They demonstrated a (t, n) visual secret sharing scheme, in which visual information is encoded into n shares so that only someone with t or more than t shares could decrypt this visual information, while nothing would be revealed by any t-1 shares. Particularly, the decryption is performed directly by stacking ...
متن کاملA Multiple Watermarking Technique for Images based on Visual Cryptography
With the explosive growth of internet technology robust methods are being developed to protect the proprietary rights of the multimedia. In this paper, an invisible watermarking technique is proposed, to embed multiple binary watermarks into digital images based on the concept of Visual Cryptography (VC). Unlike traditional watermarking schemes, the watermarks are not embedded directly into the...
متن کاملImage Encryption – An Intelligent Approach of Color Visual Cryptography
Visual cryptography is a secret sharing method that uses human eyes to decrypt the secret. It has computation-free decoding process to decrypt the images. Generally visual cryptographic methods utilize the technique of secret sharing in which secret image is divided into shares and when k shares out of n stack together the secret image will reveal. In this paper we proposed a method of visual c...
