數(shù)字水印的攻擊方法
THE ATTACK METHODS OF DIGITAL WATERMARKING
-
摘要: 數(shù)字水印是近兩年來(lái)出現(xiàn)的數(shù)字產(chǎn)品版權(quán)保護(hù)技術(shù),目的是保護(hù)數(shù)字產(chǎn)品的合法拷貝和傳播,是當(dāng)前國(guó)際學(xué)術(shù)界的研究熱點(diǎn)。數(shù)字水印包括算法設(shè)計(jì)和攻擊技術(shù)兩方面,它們是互相促進(jìn)的對(duì)立面。本文簡(jiǎn)單討論了數(shù)字水印的概念和應(yīng)用,全面分析總結(jié)了當(dāng)前數(shù)字水印的各種攻擊方法,提出了數(shù)字水印下一步的發(fā)展方向,對(duì)改進(jìn)和設(shè)計(jì)水印算法具有重要的指導(dǎo)作用。

Abstract: Digital watermarking is a technique, which protects digital product copyright and does not appear until two years ago. And its goal is to protect legal copy and distribution of digital product, it has been the hotspot of international academia. Digital watermarking includes algorithm design and attack technique, which are contrarily promoting each other. In this paper the concept and applications of digital watermarking are briefly discussed, the current various attack methods are fully analyzed and summarized. Several directions of development of digital watermarking at next stage are proposed. These are of great importance to improve and design watermarking algorithm. -
