Abstract

The invention discloses an electronic file permission dynamic adaptive control method. The method is characterized by comprising the following steps of: configuring a plurality of permission control strategies; generating and storing a control strategy tank with the plurality of control strategies; analyzing the control strategies in the control strategy tank to obtain permission characteristic codes; obtaining file identification codes of a currently operated file in a system process; analyzing the file identification codes to obtain file confidential attribute identification codes; adaptively analyzing the permission characteristic codes and the file confidential attribute identification codes; if the permission characteristic codes are matched with the file confidential attribute identification codes, generating file adaptive operation codes; according to the operation codes, encrypting and decrypting files; and, if the permission characteristic codes are not matched with the file confidential attribute identification codes, obtaining a file non-adaptive operation.
