A Robust Digital Fingerprinting Mechanism for Digital Copyright Protection

摘要

As demand for digital fulltext-image with fast development of super high speed communication network is increasing in digital contents industry, its scale is increasing exponentially every year. However, this fulltext-image is illegally reprinting and distributing widely, and this brings about the problems of its copyrights and proprietary rights. To solve this problems, many techniques such as DRM(Digital Right Management) or digital watermarking is receiving study. The digital fingerprinting is one method of right protection of new multimedia based on digital watermarking. Consequently, we design robust watermarking algorithm, which can resist a various attack, construct digital fulltext-image framework for copyright service, and apply them in our digital fulltext-image protection system.
