数字水印应用协议及关键技术研究
|
摘要
随着信息和网络技术的发展,数字版权管理问题日益突出。密码学和数字水印技术被认为是解决数字版权管理问题的两种有效方法。传统的密码学技术侧重于对数字产品的访问控制和保密通信,但是对版权认证和盗版追踪问题显得力不从心。数字水印技术作为九十年代新兴的信息安全技术,正是由于数字版权保护的需要而产生和发展起来的。与传统的密码学技术相比,水印技术在多媒体数字产品的真伪鉴别和合法用户的盗版控制方面体现出无可比拟的优势。因此数字水印技术受到越来越多的专家、学者的重视。但是目前对于数字水印的研究多集中在算法和理论基础方面,而忽视了水印的应用协议和实施标准设计和制定。而优秀的应用协议和规范往往是数字水印具体应用中不可或缺的。没有一个安全高效的水印协议的支撑,再好的水印算法在应用中也可能出现安全性问题。因此数字水印应用协议研究是克服目前水印应用瓶颈的关键。
论文主要工作和研究成果如下:
(一)介绍了数字水印应用协议的关键技术,包括密码学基础和数字水印相关技术,重点分析了PKI、数字签名、数字指纹和水印攻击对策等技术,
(二)针对目前水印协议在版权管理方面的缺陷和问题,给出了数字水印应用协议的设计思想和构建原则,
(三)提出了一个具体的改进的新的数字水印应用协议。该协议在文献[17]的基础上,借助PKI技术,结合数字签名、数字信封数字水印等技术,而设计出的安全高效的数字水印应用协议。
(四)详细分析了协议的版权管理效力和可行性。改进后的协议在安全性方面可以抵抗多种协议攻击和密码学中的中间人攻击,同时在有效保护版权的同时着重加强了合法消费者权益的保护,对商家和用户的欺诈行为进行了有效控制,达到了综合管理的目标和协议的公平性,此外协议的性能和效率也得到了显著提高。
With the development of information and network technologies, the problem of digital rights management have become increasingly prominent. Cryptography and digital watermarking technologies are considered effective methods to resolve the issue of digital rights management. Traditional cryptography technology focused on the access control and confidentiality communications of digital products, but for authentication and copyright piracy tracing it is insufficient. In the 1990s, as one of the emerging information security technologies, digital watermarking was created and developed to meet the need of digital copyright protection.Compared with the traditional cryptography technologies, digital watermarking has incomparable advantages in the identification of the authenticity of products and pirated control of legitimate users. Therefore digital watermarking technology is paid more attention by a growing number of experts and scholars. But more research of the digital watermarking focus on algorithms and theoretical basis, while ignoring the design of watermark application protocol and implementation. And excellent application protocol and norms are indispensable in the specific application of digital watermarking.Without a safe and efficient watermarking protocol, the best watermarking algorithm in the application may also have security problem. Therefore the research of digital watermarking application protocol is essencial to overcome the current bottleneck of watermarking application.
The main works and research results of this article are as follows: (A)The key technologies of the watermarking protocol are introduced, including the basis of cryptography and digital watermarking technology, and the technologises of PKI, digital signatures, fingerprints and digital watermarking attack are analysed with emphasis.
(B)In the light of shortcomings of the existing watermarking protocols, the principles of the protocol design and the thinking of creation is proposed.
(C)Based on the literature[17], a new digital watermarking application protocol is proposed. Combined with PKI, digital signatures and digital envelope technologies, this watermarking protocol is safe and effective (D)a detailed analysis of the protocol's effectiveness of the copyright management and feasibility. In the aspect of security, this protocol can be resist many kinds of attacks about protocol and intermediate attack, while it has effective protection of copyright, and at the same time focuses on strengthening the protection of the legitimate rights and interests of consumers, controlling fraudulent conduct of merchants and users effectively and realizing the integrated management of objectives and the fairness of the protocol.And the performance and efficiency of the protocol have also been significantly enhanced.
