Design And Implementation Of Tools To Generate And Manage Of The Security Classification Marked Word Electronic Documents Based On The Plug-in Technology

It's a long time that the management of paper documents is based on security classification marked in our countries, the technology of the management is mutual, but the electronic files are lacking for directive rules which are based on security classification marked. The department of the State Secrets Administrative have issued relevant standard of information system classification protected. It puts forward that the security information system should have the security classification marked and demand for the security classification marked and information are inseparable and can't changed. But in the application practice of the security classification protected, the differences exist in the implement of the technology. There are many electronic files which security classification can't be identified. It can't be controlled, tracked and recorded the electronic files which based on security classification marked. Therefore, its demand for adding security classification marked to electronic files.The design and implementation of the paper is generated and management of the security classification marked tool of the Word electronic document based on plug-in technology. The tool implements inseparable of the security classification and electronic files with watermark and plug-in technology. It also implements the application and management functions of the operating recorded of the security classification marked electronic files and changing the security classification marked. The tool main includes three parts, they are the generation of the security classification marked, setting level of the files and changing the security classification marked. The generation of the security classification marked part implements association of the watermark, electronic files and security classification marked, and set property values for security classification marked. Setting level of the files part main implements judging the permissions of the setting level people who add watermark to generate secrets level marked. The changing of the security classification marked main implements changed marked and the second generate for the security classification marked according to the certain procedures.The paper includes five parts, the first part introduces the study present situation,background and significance of the issue. The second part is general design; this part first introduces the principle and target of the system design and then introduces the needs, design process and interface of the system. The third part introduces the detail design and implementation of the every module. The fourth part main is testing the tool. The last part is summarizes and look into the distance of the issuer.
