“…The pattern applies a self-adjusted shading segment picking methodology; Pre-forms the watermark by Logistic riotous encryption. Dorairangaswamy, et al (2009) [6] has clarified an imperceptible and visually impaired watermarking plan for copyright security of computerized pictures with the objective of protecting against advanced robbery. In this watermarking plan, a double watermark picture has been imperceptibly installed into the host picture for accomplishing copyright assurance.…”

Digital watermarking enables one to protect the document; it is the kind of material authentication. The major problem in hypermedia technology is attacks on digital watermarking.In digital watermarking single attack on a given watermark image has effective outcome but multiple attacks on a given watermarked image and other watermark scrambling need to be improved. This paper purposes a new watermarking technique using integrated approach of SWT with GA and PSO for watermarking scrambling is used. The proposed methodology enhances imperceptibility and robustness in the watermarked image which has result in improving the visual quality of watermark.

“…They are known in the form of DRM which may be characterized as a system aimed at protecting digital data of high value, controlling their distribution and use [11]. The basic requirements set for the DRM system contain suitable protection of digital data against unauthorized access, suitable robustness for different types of multimedia (video, music, text, pictures), independent from the platform on which they will be used (PC, phones, TV, radio).…”

“…The basic requirements set for the DRM system contain suitable protection of digital data against unauthorized access, suitable robustness for different types of multimedia (video, music, text, pictures), independent from the platform on which they will be used (PC, phones, TV, radio). DRM consists of two components: (1) a technology of the following type: digital watermarking, encoding, copy control, authentications, tamper-resistant hardware and software, integrity checking, revocation and risk management architectures, key management, fingerprinting (2) creating technologies which allow for the use of DRM on hardware platforms [11,22].…”

The protection of copyrights of digital images authors is one of the most important tasks set before watermarking. What is especially important is to ensure the high robustness of a watermarked images against attacks, preventing the reading of additional information about the author. In addition, the used processing of the original image must be absolutely invisible. The presented algorithm embeds information in a parallel way-independently of the luminance and chrominance matrices in the spatial and frequency domains. The main factor motivating the use of a parallel watermark embedding via the proposed way was the mutual complementing of robustness, offered by processing in spatial and frequency domains. Additional information is recovered in a 2D cepstrum domain and in coefficients of the cosine transform. The article shows a description of a mathematical model, tests of invisibility, effectiveness and the robustness of the method were carried out. The robustness of the algorithm was shown against the following attacks: JPEG and JPEG2000 lossy compression, noise, median filtering, Low-Pass and High-Pass filtering, desynchronization, simple and inverse D/A conversion, majority cropping, photomontage and affine transforms-rotation, scaling, shearing, translation.
