Problems solved by technology

However, this centralized storage method will make the files easy to be modified maliciously, which will bring greater insecurity to the files, especially for some files with high security requirements, such as contract documents
If these contract documents are maliciously modified by criminals by invading the server, but the relevant personnel of the files cannot know the modification, it is easy to cause damage to the interests of both parties to the contract

Abstract

The present application discloses a file storage method, an electronic device and a storage medium thereof. The method comprises the following steps: a block chain accounting node receives the first file data; calculating the first file data by using a hash algorithm to obtain a first hash value; generating a second hash value using the first hash value and the second file data; the second hash value or both the first hash value and the second hash value are stored in a block chain for verifying whether the first file data has been tampered with. The scheme can avoid malicious tampering with the file data and ensure the reliability of the file data.

Description

technical field [0001] The present application relates to the storage field, in particular to a file storage method, electronic equipment, and a storage medium thereof. Background technique [0002] At present, various documents such as contract documents exist in two forms, one is paper form, which is not easy to store, and paper documents are easy to be lost or damaged; the other is electronic form, which is more convenient to store and not easy to store. lost. Based on the obvious advantages of electronic documents, document digitization is a form that is increasingly widely used. [0003] Today, electronic files are mainly stored in a centralized manner, that is, files are stored centrally in one or more servers. However, this centralized storage method will make the files easy to be modified maliciously, which will bring greater insecurity to the files, especially for some files with high security requirements, such as contract files. If these contract documents are ...
