“…The hidden message is got by stacking the stego images and the secret image is verified. [10] A new verifiable visual cryptography scheme (VCS) for colour image is presented by Han et.al. it fulfils the distribution and recovery of the secret image and verifiable image which relies on XOR algorithm.…”

Visual Cryptographic technique has become an important field of study in modern cryptography. Visual cryptography (VC) has quite a few applications and some of them are authentication and identification, steganography, and image encryption. As the era demands the need of security and Visual Secret Sharing to resist cheating scenario is a Visual Cryptographic technique. VSS is simple as it is easily detectable by human visual system. A secret image sharing scheme is used for identifying the existence of cheater. The use of verifiable scheme leads helps find the presence of a cheater. The problem of cheating prevention exists and researchers have proposed scheme like Cheating-prevention visual secret-sharing (CPVSS) schemes. This paper is based on the study of the cheating prevention happening in Visual Cryptography.

Visual cryptography is an encryption technique to encrypt a secret image into different shares such that stacking a sufficient number of shares reveals the secret image. Most of the previous research work on VC focuses on improving two parameters: pixel expansion and contrast. We considered the cheating problem in the visual cryptography scheme and investigate various cheating prevention schemes. During the reconstruction of the secret, one participant, called cheater, may release a false share. As a result a fake image will be revealed.

“…Use wavelets to transform the given image in the spatial domain into the frequency domain. Values in the multimedia data are stored as integers, but many wavelet transforms return real values, which cause data loss when stored in a multimedia file and then retrieved [7]. To overcome this, use the Lazy Lifting Scheme, by applying an Integer Wavelet Transform.…”

Visual secret sharing, or the so-called visual cryptography, is a well-known scheme that encrypts a secret image into several meaningless share images, usually printed on transparencies, and decrypts as stacking some or all share images by the human visual system. More and more researches about visual secret sharing and its applications have been recently proposed. Here a novel image sharing scheme is proposed to encode a secret into meaningful host images. It consists of Error Diffusion, Permutation Encoding, Steganography and Cheating Prevention. Since the secret images are grayscale images, we first apply EDBTC, then the secret image is encrypted based on permutation. Finally hide the shares created by adaptive region incrementing and cheating prevention algorithm into host images.
