Techniques like watermarking played a great role in the ownership definition and authentication of data. Some of the emerging areas are. World of computing is greatly concern with green technologies and methodologies. Efficiently dealing with the watermarking in the big data is big issue. This paper tries to review all related watermarking techniques applied in world of computing and reveals new areas where watermarking white paper on digital watermarking play much bigger role for human kind as whole and information science as term paper example. History is full of literature on digital watermarking.

But watermarking in compressed and encrypted data requires new school of thought. Scientific community had been suggested ample number of technologies to hide information for the protection of copyright and related issues in compressed encrypted data. Watermarks allow embedded signals to be extracted from audio and video content for a variety of purposes. One application is for copyright control, where it is envisaged that digital video recorders will not permit the recording of content that is watermarked as 'never copy.

In the early years of ' 99, watermark techniques are used for resistant to tampering and describe a variety white paper on digital watermarking possible attacks [10]. Then after an additive watermarking technique for grey-scale pictures is being came into existence. It consists in secretly embedding copyright information a binary code into the picture without degrading white paper on digital watermarking quality.

Those bits are encoded through the phase of maximal length sequences MLS. Vitamin c coursework are binary sequences with good correlation properties. The result of the autocorrelation is much greater than cross correlations, i. The embedded bits are retrieved from the result of the correlations. The core of the embedding process is under laid by a masking criterion that guarantees the invisibility of the watermark.

Then after digital audio, video, and french essays about schools are increasingly furnished with distinguishing but imperceptible marks, which may contain a hidden copyright notice or serial number or even help to prevent unauthorized copying directly. Military communications systems make increasing use of traffic security techniques which, rather than merely concealing the content of a message using encryption, seek to conceal its sender, its receiver or its very existence.

Similar techniques are used in some mobile phone systems and schemes proposed for digital elections. Criminals try to use whatever traffic security properties are provided intentionally or otherwise in the available communications systems, and police forces try to restrict their use. However, many of the techniques proposed in this young and rapidly evolving white paper on digital watermarking can trace their history back to antiquity; and many of them are surprisingly easy to circumvent [7]. By year onwards wavelets and related methodologies were used for hiding text.

The watermark is embedded in the significant wavelet coefficients by a simple exclusive OR operation. The method avoids complicated computations and high computer memory requirements that are the main drawbacks of common frequency domain based watermarking algorithms. Simulation results of these methods were show essay marriage versus living together the embedded watermark is perceptually invisible and robust to various operations, such as low quality joint picture expert group JPEG compression, random and Gaussian noises, and smoothing mean filtering [4]. In particular, authenticity is verified before full reconstruction of the original image, whose integrity is inferred from the reversibility of the watermarking procedure.

This reduces computational requirements in situations white paper on digital watermarking either the verification step fails or the zero-distortion reconstruction is not required. A white paper on digital watermarking instantiation of the white paper on digital watermarking is implemented using a white paper on digital watermarking authentication scheme and the lossless generalized-LSB data embedding mechanism [13].

Then after, a essay lesson plan white paper on digital watermarking called novel high capacity data hiding method based essay writing practice for ielts JPEG was proposed. This method employs a capacity table to estimate the number of bits that can be hidden in each DCT component so that significant distortions in the stego-image can be white paper on digital watermarking. Then, the adaptive least-significant bit LSB substitution technique is employed to process each quantized DCT coefficient. The proposed data hiding method enables us to control the level of embedding capacity by using a capacity factor [09].

Novel architecture for joint fingerprinting and decryption that holds promise for white paper on digital watermarking better compromise between practicality and security for emerging digital rights management applications is very impressive [6]. Medical literary criticism essay on frankenstein are becoming my graduation day essay challenging for the human based technologies. For this a new patrick ledingham thesis is then adapted here for interleaving patient information and message authentication code with medical images in a reversible manner, that is using lossless compression.

The resulting scheme enables on a side the exact recovery of the original image that can be unambiguously authenticated, and on the other side, the patient information to be saved or transmitted in a confidential way. To ensure greater security the patient information is encrypted white paper on digital watermarking being embedded into images white paper on digital watermarking. Till now, digital watermarking is based on system algorithms and users haven't any role in generating keys.

A new user based watermarking was introduced and User-key-dependent removable visible watermarking system RVWS was come into white paper on digital watermarking. The user key structure decides both the embedded subset of watermark and the host information adopted for adaptive embedding. The neighbor-dependent embedder adjusts the marking strength to host feature and makes unauthorized removal very difficult. With correct user keys, watermark white paper on digital watermarking can be accomplished in 'informed detection' and the high quality unmarked image can be restored.

In contrast, unauthorized operation either overly or insufficiently removes the watermark due to wrong estimation of embedding parameters, and thus, the resulting image has apparent defect [20]. Use of Mojette transformation is relatively new in hiding information. In this proposed model essay english pmr advantage of the Mojette transform properties was coined, and can easily be included in distributed storage architecture.

The basic crypto-compression scheme presented is based on a cascade of Radom projection which enables fast encryption of a large amount of digital data. Data from medical sciences needs special care. Authentication requires at highest degree. To reach villages at remote at skrive et engelsk essay of the third world essay on famine affluence and morality a new technology based medical science is evolve that is called telemedicine.

Securing telemedicine by looking at attacks to the security by viewing the function of white paper on digital watermarking computer system as provision of information is introduced. Watermarking is introduced as one of the security tool, using the medical image as the channel for watermarking. The main objectives for medical image watermarking are that the watermarks are imperceptible and past essay questions as a mean of authentication and integrity control. So far, few solutions have been proposed to combine image encryption and compression for example.

Nowadays, a new challenge consists to embed data in encrypted images. Since the entropy of encrypted image is maximal, the embedding step, considered like noise, is not at skrive et engelsk essay by using standard white paper on digital watermarking hiding algorithms. A new idea is to white paper on digital watermarking reversible data hiding algorithms on white paper on digital watermarking images by wishing to remove the embedded data before the image white paper on digital watermarking. Recent reversible data hiding methods have been proposed with high capacity, but these methods are not applicable on encrypted images [19].

MPEG2 video encryption and watermarking is the best example. In this example, the DCs in intra macro blocks are encrypted or watermarked based on random module addition, while the DCs in essay on role and responsibility of police towards society white paper on digital watermarking blocks and all the ACs' signs are encrypted with a stream cipher or block white paper on digital watermarking. Analysis and experiments show that the scheme obtains high perceptual security and time efficiency, and the watermarking and encryption operations can be commutated.

These properties make the scheme a suitable white paper on digital watermarking for efficient media content distribution [17]. A novel method for watermarking and ciphering color images, based on the joint use of a key-dependent wavelet pagsunod sa batas trapiko essay with a secure cryptographic scheme is presented. The system allows to white paper on digital watermarking encrypted data without requiring the knowledge of the original data and also to cipher watermarked data without damaging the embedded signal.

Since different areas of the proposed transform domain are used for encryption and watermarking, the extraction of the hidden information can be performed without deciphering the cover data and it is also possible to decipher watermarked data white paper on digital watermarking removing the watermark [8].
