基于“面向服务架构”机制的买方-卖方数字水印协议设计

Design of Buyer-Seller Digital Watermarking Protocol Based on Service-Oriented Architecture Mechanism

针对数字水印协议中买方操作量过大和水印重复嵌入问题,本研究提出一种安全、易操作、能够实现网上应用的买方-卖方数字水印协议设计方案。首先,利用"面向服务架构"机制构建各个参与方之间的交互过程,利用其适应性强、可重用性强、高效率的运营特点优化买方操作流程;其次,通过数字签名绑定买卖双方的身份信息,并与消息水印毗连生成唯一的嵌入水印,解决水印重复嵌入问题;最后,分析设计方案,确保其安全性、高效性、可行性。

In this study, the issues of the buyer＇ s excessive operation and repeated embedding in existing digital watermark- ing protocols were studied. A new buyer - seller digital watermarking protocol was proposed, which was secure, simple and easy to implement in web applications. Firstly, the mechanism of service - oriented architecture was used to construct the in- teractive process of the participants. With the characteristics of adaptability, reusability and high efficiency of this mecha- nism, the operation flows of buyers were optimized. Then, the information of buyer and seller was banded by digital signa- ture, which was adjoined with the watermark to generate a unique watermark in order to resolve the problem of repeated em- bedding. Finally, the proposed scheme was analyzed to guarantee the security, effective and feasibility
