一种基于虚拟组件的文档打印控制方法研究与实现

A Document Printing Control Method Based on Virtual Component Object Model

提出了一种基于虚拟组件的文档打印控制方法,该方法首先将各种应用系统输出的打印文件转换为PDF文件格式,然后对该PDF文件进行审批打印输出,实现了文档打印的过程控制和文档内容的安全保护,解决了文档安全打印问题。此外,该方法还可在PDF文档中隐藏用于文档来源追踪的安全标识信息,从而为因文件非法传播而造成失泄密后的溯源追踪提供了一种有效的技术途径。

This paper puts forward a document printing control method.Documents from various applications are first transformed into PDF format,then are checked and approved for printing.The contents of documents are well-protected and the control method features secure printing process.Furthermore,information of security identifier in a document is hidden for tracing purpose.An effective mechanism is designed to identify illegal transfer of documents.
