Background
With the rapid development of global informatization, information security has become a world-level key point, and archive information faces security risks in each stage of formation, processing, transmission, storage and utilization. Various management standards are issued by domestic and foreign file management organizations, various safety guarantee measures are implemented, and authenticity, integrity and effectiveness of files can be maintained while open utilization of the files is guaranteed. The existing file security problem mainly comprises three aspects:
① originality of the file contents, how to avoid human misoperation and illegal alteration during the electronic filing process of the file, and ensure the authenticity and reliability of the file contents.
②, safety of archive storage, and prevention of illegal access, tampering and theft of archive data during the storage of the archive.
③, availability of file information, namely, on the premise of ensuring the originality and authenticity of the file, how to make the file information be used efficiently among administrative units, utilization units and public individuals, realizing the credible transfer of the file and improving the utilization value of the file.
Meanwhile, hall, base, fixed point and self-service facilities cannot be shared in the whole province and city range, business file bar management and file resources cannot be shared, and the cooperation efficiency among departments, levels and regions is low. The paper material cannot be automatically transmitted along with a business process, the automatic cooperation of business links is restricted, the risks of loss, tampering and overstock exist, and the paper material is the bottleneck of business sinking, service extension, different-place business and city communication, so that business transactors run back and forth, and the burden of people for acquiring services is increasingly heavy.
