File identification method, system and device based on black and white lists

Abstract

The invention discloses an archive identification method, system and device based on a black list and a white list. The method comprises the following steps: classifying electronic files to be authenticated in an office automation system according to a preset file type, and obtaining the identification rule and the black/white list which are set in advance and correspond to the file type of the electronic file to be identified, wherein the keywords of the electronic file to be identified belonging to a specific storage life are stored in the white list, and the keywords of the electronic fileto be identified excluding the electronic file to be identified belonging to the specific storage life are stored in the black list; extracting metadata of the electronic file to be authenticated; orextracting metadata and keywords of the to-be-authenticated electronic file, comparing the keywords extracted from the metadata or the keywords extracted from the metadata and the to-be-authenticatedelectronic file with the keywords in the black list and/or the white list according to the obtained authentication rule, and finally determining the storage life of the to-be-authenticated electronicfile. According to the invention, the accuracy of archived electronic file identification is further improved.

Description

technical field [0001] The invention relates to the technical field of file identification, in particular to a file identification method, system and device based on a black and white list. Background technique [0002] Appraisal is an important part of archives management. Over the years, the archival identification work has been completely done manually, and the workload is relatively large. Especially for archiving and identification, under the current situation of rapid development of the digital economy, a large number of electronic documents are produced, and the workload of electronic document archiving and identification has increased significantly on the original basis. In the electronic archives management system (hereinafter referred to as the archives system), it is of great significance to realize the intelligentization of archives appraisal through a certain method, which is of great significance for improving work efficiency and realizing the automatic manage...

Problems solved by technology

[0005] The disadvantage of the manual classification and identification method is that although this method embeds the file storage schedule in the office automation system or the file system, selecting the classification method through the drop-down menu adds more work than directly identifying electronic files manually quantity

Obviously, although this overly rough and general identification method increases the proportion of documents that can be automatically identified, the accuracy of the identification cannot be guaranteed. It is actually another extreme approach to the information matching identification method based on the rule base.
