Problems solved by technology

[0002] Electronic files refer to files generated in digital devices and environments, stored in digital form on magnetic tapes, magnetic disks, optical discs, etc. Documents have become one of the important means of unit notification, document circulation, and evidence transmission. However, in the process of electronic document circulation and transmission, electronic documents are easily tampered by illegal personnel, thereby transmitting false information, and electronic document circulation is tamper-proof. Poor ability, there are certain deficiencies

Abstract

The invention relates to the technical field of electronic file circulation tamper-proofing, in particular to an electronic file circulation tamper-proofing method and device. The electronic file circulation tamper-proofing method comprises the following steps: generating an electronic file; encrypting and storing electronic file data; extracting, comparing and broadcasting electronic file data; and extracting electronic file data. According to the invention, electronic file data is copied, and then a data hash value is extracted. One of the two data hash values is stored in the same cloud server, and the other data hash value is distributed and stored in a plurality of different cloud servers. The different storage modes of the two data are beneficial to confusing lawbreakers. After a lawbreaker changes the hash value of any one piece of data, before circulation, the two pieces of data need to be compared; and if the two pieces of data are different, the file cannot be broadcasted, so that the situation that the data is transferred after being tampered is avoided, and the security of the electronic file is guaranteed.

Description

technical field [0001] The invention relates to an anti-tampering method for electronic files, in particular to an anti-tampering method and device for electronic file circulation, and belongs to the technical field of anti-tampering for electronic file circulation. Background technique [0002] Electronic files refer to files generated in digital devices and environments, stored in digital form on magnetic tapes, magnetic disks, optical discs, etc. Documents have become one of the important means of unit notification, document circulation, and evidence transmission. However, in the process of electronic document circulation and transmission, electronic documents are easily tampered by illegal personnel, thereby transmitting false information, and electronic document circulation is tamper-proof. The ability is poor and there are certain deficiencies. [0003] For the above problems, this invention is proposed. Contents of the invention [0004] The purpose of the present...
