摘要 隨著計(jì)算機(jī)網(wǎng)絡(luò)、多媒體技術(shù)的飛速發(fā)展,數(shù)字化媒體資源已成為信息主流方式。數(shù)字產(chǎn)品易于編輯、復(fù)制、傳輸?shù)奶攸c(diǎn)一方面促進(jìn)了人類信息的共享,另一方面隨之而來(lái)的數(shù)字版權(quán)保護(hù)和內(nèi)容認(rèn)證問(wèn)題也變得突出,成為了當(dāng)下數(shù)字世界迫切需要解決的問(wèn)題。傳統(tǒng)的密碼學(xué)技術(shù)已不能有效解決數(shù)字版權(quán)保護(hù)問(wèn)題,數(shù)字水印技術(shù)應(yīng)運(yùn)而生。
本文首先對(duì)版權(quán)認(rèn)證的研究背景與研究意義進(jìn)行了簡(jiǎn)介;然后對(duì)數(shù)字水印技術(shù)進(jìn)行了研究;在對(duì)數(shù)字版權(quán)認(rèn)證保護(hù)系統(tǒng)的應(yīng)用需求進(jìn)行分析的基礎(chǔ)上,本文提出了一種基于B/S(Browser/Server)模式的數(shù)字圖像版權(quán)保護(hù)系統(tǒng)的方案。該方案以B/S模式為基礎(chǔ),將系統(tǒng)分為系統(tǒng)管理、水印處理以及版權(quán)認(rèn)證這三個(gè)模塊,并采用代表性的數(shù)字圖像算法實(shí)現(xiàn)水印的嵌入與提取;最后本文利用Microsoft Visual Studio 2005和MATLAB2009a等開發(fā)工具對(duì)版權(quán)認(rèn)證保護(hù)系統(tǒng)的流程進(jìn)行了實(shí)現(xiàn)。
測(cè)試結(jié)果表明,該系統(tǒng)能提供安全有效的版權(quán)認(rèn)證和保護(hù),具有安全性、公平性、可靠性以及實(shí)用性,具有較好的應(yīng)用前景。

Copyright Authentication Applications Based on Digital Watermarking Technology
Abstract With the rapid development of computer network and multimedia technology, digital media resources have become a mainstream way of information. The digital product’s characteristics are easy to edit, copy, transmit and etc. It promotes to share the information, on the contrary, it poses a thread on the digital copyright protection and the content authentication. Digital watermarking technology comes into being under the background that the traditional cryptography techniques can not solve the problem of copyright protection effectively.
Firstly, this paper gives an introduction to the research’s background and significance for the copyright certified; Then analyzing the digital watermarking technology; After that, on the basis of the application requirements for digital copyright protection system analysis, this paper proposes a scheme of digital image copyright protection system based on B/S(Browser/ Server)Mode. The system is divided into management, watermark process and copyright certification of these three modules, taking advantage of digital image representation algorithm to make watermark embed and extracted; Finally, making copyright protection system processes come true via Microsoft Visual Studio 2005 and MATLAB2009a.
The test results show that the system can provide safe and effective authentication and copyright protection, with security, fairness, reliability and practicality, it owns a good prospect.
