“…This result in less embedding capacity still it achieves substantial robustness. For a J x K size of host image, the number of blocks, k, using NxN DCT transform is given by (1). Total embedding capacity is same as the number of NxN blocks which is given by k.…”

The chances of copyright violation and piracy have been increased due to growth of networking and technology. Digital watermark is useful to verify the integrity of the content and for authenticity of an owner. The digital watermark must be robust against various attacks in order to protect the copyright information which is embedded in the original content. The proposed algorithm is useful for protecting the distribution rights of digital images. Watermark is embedded in the DCT coefficients of the host image and the watermark is pseudo randomly spread over the entire image using Linear Feedback Shift Register (LFSR). The algorithm shows improvement over existing algorithms in terms of Normalized Correlation (NC), Tamper Assessment Function (TAF) and Peak Signal to Noise ratio (PSNR). The proposed algorithm outperforms the related previous work with better results.

“…For the unfairness between multicaster and subscriber of the scheme, the arbitration is invalid. This is the subscriber's right problem, and is first put forward by Emmanuel and Kankanhalli in 2003 [1], and they proposed a solution to solve this problem for digital video multicasts.…”

Today, much multicast fingerprint schemes have been proposed to protect the digital content's copyright in multicast environment. All of those schemes only consider the distributor's right. The generation and the embedding of the fingerprint are controlled by the distributors. Since that, the accusation against the charged redistributor, who was the subscriber in some earlier transaction, is rejected because that the distributor can also get the distributed fingerprinted copy to this subscriber. This is known as the subscriber's right problem. In Emmanuel and Kankanhalli 2003, they propose a scheme to protect both the distributor's copyright and subscriber's rights for digital video multicast. But in their scheme, they never consider the unbinding problem and the privacy of the subscriber. In this paper, we proposed an anonymous multicast fingerprinting scheme, to fix the Emmanuel and Kankanhalli's scheme by solving the unbinding problem, protecting the subscriber's privacy through a trusted third party. The result is a security, fair and anonymous multicast fingerprint protocol.

“…Hence, concerns about protection and enforcement of intellectual property (IP) rights of the digital content involved in the transactions, have also been mounting. The emerging field of digital rights management (DRM) systems [3,9] addresses these issues related to ownership rights of digital content. Two basic goals of DRM systems that can be met with digital watermarking are: i) preventing unauthorized use of the images (in general, any digital information), particularly for commercial purposes and ii) providing visibility to the authentic source or the owner of the information on a continuous basis.…”

With the explosive growth of internet technology, many innovative applications requiring exchange of large amounts of multimedia data have become feasible. However, this kind of convenience with which authorized users can access information, turns out to be a mixed blessing because of information piracy. The emerging field of digital rights management (DRM) systems addresses the issues related to the intellectual property rights of digital content. In this paper, we present a novel invisible watermarking method that uses cryptography and watermarking methods simultaneously to provide a double layer protection to the digital media which can be an effective technique for DRM. Our proposed method securely hides binary information in color image media, and securely extracts and authenticates it using a secret key. Experimental results prove that our proposed invisible watermarking techniques is resilient to 90% of the well known benchmark attacks and hence a failsafe method for providing constant protection to the ownership rights.
