A method and apparatus for restricting user from accessing electronic document

Abstract

The invention discloses a method and device for limiting a user from accessing an electronic document, and the method comprises the following steps: S1, carrying out the grading of the electronic document through a preset method, and storing the electronic document in an electronic document metadata folder; s2, grading the visitors by adopting a prefabrication scheme; and S3, comparing and judging the visitor level with the folder level accessed by the visitor level, and carrying out adaptive response. The method has the advantages that documents are managed in a centralized mode, so that electronic documents are better and more conveniently shared, the comprehensive utilization value of the electronic documents is improved, the electronic documents are managed and controlled in a centralized mode, and it needs to be guaranteed that the electronic documents can still be protected according to the importance degree of the electronic documents after centralized management and control; besides, the user and the document are graded, and whether the user is matched with the grade of the document accessed by the user or not is judged, so that the document access permission of the user is limited, and the problem of information leakage caused by improper sharing of confidential information is prevented.
