摘要
通过对目前数字图书馆信息资源产权保护的国内外研究现状的分析,指出目前采用的产权保护技术不能对遭受恶意篡改的数字作品进行篡改定位、篡改内容恢复以及原始作品的可逆还原。同时由于篡改会导致水印不能正确提取,从而引起认证失败。针对这些问题,提出一种利用最新的压缩感知理论及智能可逆水印技术以更好地实现数字图书馆信息资源产权保护的无损认证方法。
Through the analysis of the research situation of recent information resource copyright protection of digital li- brary, this paper points out that the existing copyright protection technology can not work well on a tampered digital product for tampering location, recovering of tampered content and restoring of origin product. At same time, tampering can result in a failure for digital product authentication due to that the extracted watermarking is not correct. To solve these problems, a method of lossless authentication using the newest compressed sensing theory and intelligent reversible watermarking technology is presented to realize the copyright protection of information resource of digital library.
