چکیده
There is an increased interest, by content creators and owners, in content protection systems that provide the ability to control or restrict the content that can be shared on peer-to-peer file sharing systems. At the same time, there is much debate that argues that content protection in peer-to-peer systems will unfairly restrict the users’ ability to share content. We explore the issue of content protection in peer-to-peer systems. We examine the benefits that it would provide to many parties including peer-to-peer network operators, individual and institutional content providers, and ultimately end-users. We then examine the challenges involved–the often conflicting goals of content providers and users. We explore how a content protection system can maintain the features that interest end-users such as an open peer-to-peer sharing experience, privacy, and flexible business models. We outline the design objectives of such a protection system. We discuss how previous attempts at content protection in peer-topeer systems only supported basic business models and show how protection systems can provide the flexibility necessary to support common content distribution business models. We explain the design space and examine proposed systems for centralized and decentralized content protection systems.

متن کاملA Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...
متن کاملDigital image watermarking: its formal model, fundamental properties and possible attacks
While formal definitions and security proofs are well established in some fields like cryptography and steganography, they are not as evident in digital watermarking research. A systematic development of watermarking schemes is desirable, but at present, their development is usually informal, ad hoc, and omits the complete realization of application scenarios. This practice not only hinders the...

متن کاملDeveloping a Benchmark Model for Image Digital Watermarking
Digital watermarking is the process of conveying information by imperceptibly embedding it into the digital media. Benchmarking is used to evaluate the watermarking algorithms. Different benchmarks are available for digital watermarking. These benchmarks work efficiently but they are complex, difficult to understand, so a new benchmark is introduced in his paper which is GUI (Graphical user int...
