在涉密数字档案管理中,应根据不同密级档案的保密利用要求、数字档案的不同文件格式、刻录光盘载体的特点,采用不同的加密技术控制其利用方式,如采用图片加密精灵加密jpg格式的数字档案图像,采用优道文档保护器加密PDF格式的数字档案文档,采用光盘加密大师伪装和隐藏刻录光盘上的数字档案文件,以达到控制光盘载体数字档案利用方式的目的。本文论述了采用图片加密精灵加密jpg格式的数字档案图像,采用优道文档保护器加密PDF格式的数字档案文档,采用光盘加密大师伪装和隐藏刻录光盘上数字档案文件的技术方法,以达到控制光盘载体数字档案利用方式的目的。
In the management of classified digital archives, different encryption schemes should be used to control their utilization according to the requirements of confidentiality and utilization of different classified files, the different file formats of digital archives, the characteristics of the recorded optical disc carriers, and the use of jpg format Digital archive image, using excellent document protection device to encrypt digital PDF files in digital format, using optical disk encryption masters to disguise and hide digital files on the disc to achieve the purpose of controlling the use of digital files carrier. This paper discusses the use of image encryption wizard encryption jpg format digital archive image, the use of excellent document protection device to encrypt digital PDF files in digital format, the use of optical encryption masters masquerade and hide the digital recording files on the disc technology to achieve the control disc The purpose of carrier digital file utilization.
