Design And Implementation Of A Secure Electronic Document System

The secure electronic document system is a system that design security mechanisms,security management on the technology of electronic document or digital paper.It is comprehensive use of technology of electronic document format,layout shows,security mechanisms,security management.To design a general electronic document security system,it is necessary to design an electronic document format,and the document format itself must have security mechanisms,such as anti-copy,anti-print,anti-copy screen,bind the hardware information,at the same time be able to design the majority of document conversion tool for documents,the reader for document format showing,and the reader Supported plug-in,the plug-in can be extended as digital library,electronic seal,electronic documents for government offices,etc.In addition,security mechanisms to design on-line,off-line security mechanism and security management functions.There are large number of companies providing digital library systems,electronic seal, document management systems,electronic documents for government offices and so on belong to the security aspects of electronic document system,which generally take a proprietary format to achieve the functions of confidential documents and general document format compatible it is very difficult,if a general international document format, PDF format,then in its package,not only solved the problem of interoperability,but also solve the security issue format.To PDF format, based on more sophisticated and widely learned the essence of open source code,to a certain degree of security mechanisms,as well as plug-in mechanism design,which can be cost-effective completion of the safety of a generic electronic document system design and...
