“…The issue of watermark removal is often addressed in watermarking literature and remains an important concern [9]. There are a number of other issues, some technical and some non-technical, which have also come to play an important role.…”

“…Second, the watermark detector needs logic to recognize the MPEG data-type. This task may become challenging since there are a number of possible circumvention strategies [9], including PC device drivers that intentionally read-out disk sectors in random order. Increases in DVD drive data rates will place higher demands on such MPEG detection and watermark detection circuitry.…”

“…Another documented "attack" on watermarks is called sensitivity analysis in which a detector is used to reconstruct the watermark in a frame by a systematic degradation of the image. Again, once found, the watermark can be subtracted from the video source [9,12]. The field of watermark removal is very active and the robustness of watermarking techniques is constantly being challenged.…”

Abstract--The prospect of consumer digital versatile disk (DVD) recorders highlights the challenge of protecting copyrighted video content from piracy. We describe the copy protection system currently under consideration for DVD. The copy protection system broadly tries to prevent illicit copies from being made from either the analog or digital I/O channels of DVD recorders. An analog copy protection system is utilized to protect the NTSC/PAL output channel by preventing copies to VHS. The digital transmission of content is protected by a robust encryption protocol between two communicating devices. Watermarking is used to encode copy control information retrievable from both digital and analog signals. Hence, such embedded signals avoid the need for meta-data to be carried in either the digital or analog domains. Finally, the copy protection system provides the capability for one-generation copying.We discuss some proposed solutions and some of the implementation issues that are being addressed.

“…This sequence is different for each content, so the average attack is useless. And finally, the detection algorithm is not linear which makes the attack of [12] non valid. Although this watermarking technique has, for the moment, only one bit of capacity, a copy protection system for digital contents can be based on it.…”

Section: Security Point Of Viewmentioning

“…It clearly appears that the embedding and detection processes have a common parameter called the key. Thus, comparing to a cryptography system, current watermarking techniques are symmetric schemes [12]. The key parameter is usually called the secret key in reference to Kerckhoffs cryptographic principle [14]: A cryptographic algorithm can not remain secret, hence the security of a cryptosystem must only rely on the key kept in a safe place.…”

Abstract. The new watermarking technique 1 presented in this paper is an example of an asymmetric public detection scheme. The detection process does not need the original picture nor the secret key used in the embedding process. It is the translation, in the watermarking domain, of a public key pair cryptosystem. The key idea is to filter the pseudo-noise sequence before embedding it in the cover-content. Contrary to classical techniques, the heart of the detection algorithm is not a correlation measure but a consistent statistical test hypothesis in spectral analysis. Some signal based considerations show that knowing the public key used in the detection process is no use for pirate who wants to discover the secret key. An example of a copyright protection system for digital content using this technique is briefly described.

With ceaseless utilization of web and other online advances, it has turned out to be amazingly simple to imitate, discuss, and convey digital material. Subsequently, confirmation and copyright assurance issues have been emerged. Text is the most widely used media of communication on the web as compared with images and videos. The significant part of books, daily papers, websites, commercial, research papers, reports, and numerous different archives are just the plain text. Therefore, copyrights protection of plain text is a critical issue that could not be accepted at all. This paper presents a concise analysis on information hiding techniques and their consequences. Various watermarking systems properties are highlighted along with different types of attacks and their possible defenses. Additionally, the current applications for text document watermarking and the reasons for the problems of text document watermarking are described. Finally, attacks characteristics are discussed including types of attacks, volumes, and nature on text. Current watermarking approaches are reviewed in depth, and consequently, their advantages and weaknesses are highlighted.
