Information security storage and transmission method and device and electronic equipment

Abstract

The invention provides an information security storage and transmission method and device and electronic equipment, and the method comprises the steps: generating an electronic certificate according to the modified information when the modification operation of any information transfer node on the information is received, and enabling the electronic certificate to correspond to the information stored in a data storage center; whether the electronic certificate is legal or not is judged according to an electronic certificate bookkeeping sheet, and the electronic certificate bookkeeping sheet is pre-stored in the block chain and used for recording the circulation process of the information; and if the electronic certificate is illegal, not updating the electronic certificate bookkeeping sheet. According to the method and the device, the electronic certificate recorded in the electronic certificate bookkeeping sheet and the information of the data storage center can be verified, so that the information which is not tampered can be traced. The block chain technology is adopted, information decentralized storage and archive circulation are achieved, the information can be true and credible like a real entity archive in the physical world, and the authenticity, reliability, safety and effectiveness of the information are improved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method, device and electronic equipment for secure storage and transmission of information. Background technique [0002] In the digital production process of archives and the reception, management, preservation and utilization of electronic archives, there is a risk of electronic archives being tampered with. At present, the common anti-tampering technologies for electronic archives are as follows. [0003] The first is the use of electronic watermarking technology. The feature of this technology is to add electronic watermarks to the original electronic files, which ensures that the electronic files cannot be modified once they are confirmed. The advantage is that the authenticity of the electronic files can be guaranteed. Normal modification cannot be realized in the subsequent circulation process, that is, electronic files with watermarks will not be able to be circula...

Problems solved by technology

[0007] In view of this, the embodiment of the present invention provides an information security storage and transmission method, device and electronic equipment to solve the problem in the prior art that once the electronic file is modified during the circulation process, it cannot be traced back to its state before it was tampered with. defect
