File measurement and protection method and device

Abstract

The invention provides a file measurement and protection method and device. The method includes the steps that at least one secure container is arranged, application programs and files are stored in each secure container, access strategies are configured, when any first secure container is started, the application programs and the files stored in the first secure container are measured, whether the application programs and the files stored in the first secure container are tampered with or not is judged, and if yes, running of the corresponding application programs or opening of the corresponding files is stopped; when any first application program accesses the current file in the current secure container, if the first application program is not an application program in the current secure container, the first application program is not allowed to access the current file, otherwise, whether an access request of the first application program meets the access strategy of the current file or not is judged, if yes, the first application program is allowed to access the current file, and otherwise, the first application program is not allowed to access the current file. According to the scheme, the protection for the application programs and the files can be strengthened.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a method and device for measuring and protecting files. Background technique [0002] With the continuous development and popularization of computer technology, computer security issues have been highlighted, and more and more users have paid more and more attention to it. Some illegal users often delete or modify applications or files to achieve the purpose of destroying the system and stealing information. Once the applications or files in the computer are maliciously modified or deleted, when running these applications or opening files, It will lead to abnormal operation of the computer or theft of information. For some important servers, if they cannot work normally or cause information leakage, it will cause serious consequences and bring huge losses to users. [0003] At present, the protection method for the application program and the file is mainly to check th...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the prior art protection methods for applications and files can only check the integrity of the applications and files before the application runs, which belongs to the method of post-processing, that is, when the application or file is found to be incomplete , the application or file has been modified, therefore, the existing protection for the application and file is relatively low
