基于数字水印的买卖交易系统
摘要
随着多媒体技术和网络技术的飞跃发展和广泛应用,迫切需要建立完善的数字产品版权保护方案来保护版权拥有者的权益。数字水印技术是一种可以在开放的网络环境下保护数字产品版权和追溯盗版来源的技术,它通过一定的算法在数字声音、图像、文档或视频码流中嵌入一些版权信息,用以证明原创作者对作品的所有权或作为鉴定盗版、侵权源的证据,但不影响原内容的价值和使用,并且不能被人的知觉系统觉察或注意,它与原始数据紧密结合并隐藏在其中,成为宿主数据不可分离的一部分,并且在需要时还可以被作为证据提取出来。
本论文首先在分析国内外各种数字水印协议的基础上,提出了一种新的基于数字水印的买卖交易协议,强调了水印认证中心的重要作用,全面保障了买卖双方的合法权益。并在该协议的基础上提出了基于数字水印的买卖交易系统,详细介绍了该系统的交易流程。
然后,阐述了与系统相关的技术,如数字水印、RSA公开密钥密码体制、数字签名、时间戳等技术,同时给出了其相关的MATLAB程序。
最后,本论文并用软件模拟实现了基于数字水印的买卖交易系统,并实现了盗版追踪的全过程。
With the rapid development of multimedia technologies and web, the perfect product copyright protection project need to build up urgently. This project would protect the rights of the copyright owns.
Digital watermarking has been presented as a new method for copyright protection and the trace of the copies by embedding a secret signal in a digital image or video sequence. Digital watermarking describes methods and technologies that allow hiding information, for example a number or text, in digital media, such as images, video and audio. The embedding takes place by manipulating the content of the digital data, that means the information is not embedded in the frame around the data. The hiding process has to be such that the modifications of the media are imperceptible. For images this means that the modifications of the pixel values have to be invisible.
At first, through analyzed the previously proposed protocols, this paper designs a new buyer-seller protocol based on digital watermarking. Then it discusses the effect of The Watermarking Certification Center in the protocol, and protects the tights of the sellers and buyers at one time. Then, this paper designs a buyer-seller system based on the protocol.
At second, this paper introduces the technology of the system, such as the digital watermarking, RSA, Digital Signature and Timestamp technologies. It makes programs for them.using MATLAB.
At last, this paper makes program for the buyer-seller system based on digital watermarking.
