Abstract

The invention provides a data storage method and device, and a storage medium. The method comprises the steps of determining a first operation permission of a file based on file configuration information; generating a first operation contract corresponding to the file, wherein the first operation contract comprises a first operation authority; storing the file, generating a first operation limiting block according to the first operation contract, and publishing the first operation limiting block in a block chain; obtaining a first operation contract based on the first operation limiting block;and obtaining a first operation authority from the first operation contract, and performing corresponding operation on the file based on the first operation authority and the operation request. According to the method, the device and the storage medium disclosed by the invention, the operation authority of the file is stored by utilizing the tamper-proof characteristic of the block chain, and theoperation is verified based on the operation limiting block, so that the operation of all data is controlled, data tampering and data embezzlement are avoided, and the authenticity and the availability of the stored file are effectively ensured.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular, to a data storage method, device and storage medium. Background technique [0002] At present, the object storage system undertakes a large number of unstructured data storage tasks. The block storage and file system based on object storage are currently the two most widely used storage methods. At present, data in all walks of life is showing explosive growth. Faced with the huge data volume and data reliability requirements, many companies choose object storage technology as a storage solution. However, the current object storage system only provides traditional asymmetric encryption methods to protect data. Although it can protect data to a certain extent, it cannot provide highly reliable storage services. Contents of the invention [0003] In view of this, a technical problem to be solved in the present disclosure is to provide a data storage method, de...
