Watermarking for Multimedia Security Using Complex Wavelets
This paper investigates the application of complex wavelet transforms to the field of digital data hiding. Complex wavelets offer improved directional selectivity and shift invariance over their discretely sampled counterparts allowing for better adaptation of watermark distortions to the host media. Two methods of deriving visual models for the watermarking system are adapted to the complex wa...
متن کاملProposing an effective approach for Network security and multimedia documents classically using encryption and watermarking
Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...
متن کاملMultimedia Security: Watermarking Techniques
A recent proliferation and success of the Internet, together with availability of relatively inexpensive digital recording and storage devices has created an environment in which it became very easy to obtain, replicate and distribute digital content without any loss in quality. This has become a great concern to the multimedia content (music, video, and image) publishing industries, because te...
متن کاملDigital Watermarking for Multimedia Security Management
This chapter is intended to disseminate the concept of digital watermarking for multimedia security management in general, and multimedia copyright protection and content integrity verification in particular. We will be addressing the challenges posed to multimedia security management and how digital watermarking can be deployed in different applications in order to meet those challenges. Categ...
متن کاملSpread transform video watermarking using 3D complex wavelets
A novel video watermarking system is presented that uses a spread transform technique to securely embed data into a video sequence, resistant to both spatial and temporal attacks. The system makes use of the 3-D wavelet domain, improving embedding by extending this to include complex as well as discretely sampled wavelet transforms. To ensure imperceptibility an adaptation of a proven video vis...
