【摘要】 针对通常数字水印系统不能提供面向网络的水印嵌入和水印检测服务的问题,设计了一种基于WebSer vices的安全数字水印方案,将水印嵌入和水印检测技术作为WebServices组件发布到Internet上.整个系统基于WebServices架构,通过简单对象访问协议(SOAP)交换服务请求者和服务提供者之间的信息,并用数字证书、XML(extensiblemarkuplanguage)加密和数字签名等安全技术保证了信息交互的安全性.该方案的提出可以降低数字水印系统的开发成本,在开放的网络环境中有效地保护数字产品.更多还原

【Abstract】 A common digital watermark system does not provide watermark inserting and detecting services on Internet. In order to make wider application of digital watermark, a new scheme to make traditional watermark available as Web Services was presented. It was based upon Web Services for inserting watermark and detecting watermark and used simple object access protocol (SOAP) to exchange messages between service requester and service provider. Based on digital certificate and extensible markup language (XML) encryption and digital signature technology, a secure interaction between the requester and the provider was provided. This scheme reduces cost and protects digital products effectively on open networks.更多还原
