Intellectual Property Protection Systems and Digital Watermarking
Adequate protection of digital copies of multimedia content - both audio and video - is a prerequisite to the distribution of this content over networks. Until recently digital audio and video content has been protected by its size: it is difficult to distribute and store without compression. Modern compression algorithms allow substantial bitrate reduction while maintaining high-fidelity repro...
متن کاملDigital Watermarking for Protection of Intellectual Property
Digital watermarking techniques have been developed to protect the copyright of media signals. This chapter aims to provide a universal review and background about the watermarking definition, concept and the main contributions in this field. The chapter starts with a general view of digital data, the Internet and the products of these two, namely, the multimedia and the e-commerce. Then, it pr...

متن کاملWatermarking for intellectual property protection - Electronics Letters
A new watermarking method for intellectual property (IP) protection is presented. The proposed method uses a uniquely generated stream of bits, known as a watermark, embedded into the self-test circuit to represent ownership. This scheme can detect the ownership rights of the IP provider even when the chip has been packaged. Experimental results show the proposed embedding technique can survive...
متن کاملIntellectual Property Protection Via Hierarchical Watermarking
Intellectual property copyrights are protected by means of patents and nondisclosure agreements. In many cases however copyright laws cannot be effectively enforced due to the difficulty of proving or even detecting infringement. This problem is addressed in the paper using a scheme known as watermarking. The method consists of implanting a semi-transparent unique signature in the circuit’s int...
