“…Visual cryptography [13][14][15] is such one kind of lossless watermarking scheme which furnishes the requirement by utilizing the codebook concept to divide an image into several different sharing images and produce the same by stacking when a dispute for ownership arises.Visual cryptography serves as a good technique against tampering of digital media and proving its rightful ownership and gained much attention for researchers in recent years. Many watermarking schemes based on visual cryptography have already been proposed [19][20][21][22][23][24][25][26]. The basic idea is to generate two shares of the watermark…”

A visual cryptography based watermarking scheme incorporating the concepts of singular value decomposition (SVD) and the homogeneity analysis of the cover image is proposed here. Firstly, feature vectors are created from the singular values of the homogeneous blocks and thereby classified using the k-medoid clustering technique. A master share is then constructed based on the clustering result and thereafter, combined with the secret binary image (watermark) ownership share is build up. This ownership share is registered with the certificate authority in case to resolve any dispute regarding rightful ownership of the image in future. A two-out-of-two visual cryptography scheme is being used in the proposed methodology and robustness validated by applying comprehensive set of attacks. The peak signal to noise ratio (PSNR) and normalized cross correlation (NCC) metric values are used for evaluation of the scheme. Higher values of these metrics establish the appropriateness of the proposed methodology as compared to the other state of art schemes for copyright protection.

“…The model of our scheme includes three kinds of participants (most VC-based watermarking schemes adopt similar models as to ours [2,4,7,9]): the owners of the cover images who want to protect their copyright of the cover images, the attackers who want to illegally use the cover images and a TA who will arbitrate the ownership of the cover images when a dispute occurs. Generally, we assume that, t owners own n images, and there is only one TA, where t and n are positive integers.…”

Watermarking is a technique to protect the copyright of digital media such as image, text, music and movie. In this study, a robust watermarking scheme for multiple cover images and multiple owners is proposed. The proposed scheme makes use of the visual cryptography (VC) technique, transform domain technique, chaos technique, noise reduction technique and error correcting code technique where the VC technique provides the capability to protect the copyright of multiple cover images for multiple owners, and the rest of the techniques are applied to enhance the robustness of the scheme.

“…In recent years, a number of scholars [11][12][13][14][15][16][17][18] have begun to focus on image copyright protection based on a combination of the visual secret sharing (VSS) 19 and traditional watermarking techniques. In this scheme, a verification image, called ownership share, can be produced from the host image feature and watermark; then the ownership share is registered to a certified authority (CA).…”

Abstract. A robust copyright scheme for image protection based on visual secret sharing (VSS) and Bose-Chaudhuri-Hocquenghem (BCH) code techniques is proposed. This scheme not only maintains the quality of a host image without the change of any pixel value but also generates a meaningful ownership share to improve the management of image copyright. In addition, no codebook is required to store, and the watermark size is independent of the host image. The robustness of watermarking can be enhanced by BCH code. The proposed scheme contains ownership share construction and watermark extraction. In the first phase, an encoded watermark is generated by BCH code from a watermark. Next, an image feature is then extracted by the discrete wavelet transform decomposing from the host image. Finally, an ownership share can be generated by VSS technique from the image feature and the encoded watermark. In the second phase, a master share can be produced from a suspect image. By stacking the master and the ownership shares and using BCH code, an extracted watermark can be obtained. The experimental results show that the proposed scheme using the BCH(15,5) has better robust performance and practicability than existing schemes.
