“…Where possible, they will use patented algorithms (even if these are not much good) as a means of imposing licensing conditions on manufacturers. For example, the DVD Content Scrambling System was used as a means of insisting that manufacturers of compatible equipment signed up to a whole list of copyright protection measures [5]. This may have come under severe pressure, as it could prevent the Linux operating system from running on next-generation PCs; but efforts to foist non-open standards continue in many applications from SDMI and CPRM to completely proprietary systems such as games consoles.…”

“…However, note that in copy protection, a pirate should not be able to change content status to a less restrictive one (e.g., from 'Copy Never' to 'Copy Once') [3]. In fingerprint, a collusion (group of pirates) should not frame an innocent user, i.e.…”

“…It allows to firmly bound content with metadata such as the copyright holder identity (copyright protection [2]) or the copy status (copy protection [3]). At that time, the naïve rationale was: "If you can't see it, and if it is not removed by common processing, then it must be secure".…”

Abstract. Digital watermarking studies have always been driven by the improvement of robustness. Most of articles of this field deal with this criterion, presenting more and more impressive experimental assessments. Some key events in this quest are the use of spread spectrum, the invention of resynchronization schemes, the discovery of side information channel, and the formulation of the opponent actions as a game. On the contrary, security received little attention in the watermarking community. This paper presents a comprehensive overview of this recent topic. We list the typical applications which requires a secure watermarking technique. For each context, a threat analysis is purposed. This presentation allows us to illustrate all the certainties the community has on the subject, browsing all key papers. The end of the paper is devoted to what remains not clear, intuitions and future studies.

“…Digital watermarking is intended to complement cryptographic process (Bloom, 1999) and Steganography. A specific code or mark is embedded permanently inside a cover multimedia file which remains within that cover invisibly or visibly even after decryption process.…”

Problem statement: Piracy in the presence of internet and computers proves to be a biggest damage to the industry. Easy editing and copying of images yields a great damage to the owner as original images can be distributed through internet very easily. To reduce the piracy and duplicity of the digital multimedia files, digital watermarking technique is dominating over the other available techniques. There are certain methods or attacks which are used to damage the watermark. One of the major attacks is histogram equalization and reducing the number of histogram equalized levels. Thus, there is a need to develop a method so that the watermark can be protected after histogram equalization. Approach: A blind digital watermarking algorithm is presented which embed the watermark in frequency domain. Firstly, DWT is applied on the original image and then DCT on the 4×4 blocks to target the particular frequencies of the image for embedding the watermark which does not have more effect after histogram equalization. Also, to enhance the security of the watermark dual encryption technique is deployed. Results: Algorithm applied to four images which are Lena, Cameraman, Baboon and Peppers. The evaluation of the algorithm is calculated in terms of peak signal to noise ratio and non correlation. The results prove that the algorithm is robust to histogram equalization attack up to 2 grey levels. Conclusion/Recommendations: The developed algorithm proved its performance against histogram equalization but the algorithm can also be checked for the other attacks which can be addition of white noise, Gaussian noise, filtering.
