Method for safe data backup, client side and cloud server side based on alliance chain

Abstract

The invention discloses a safe data backup method, a client side and a cloud server side based on an alliance chain. On the client side, the method comprises the steps that a target document to be backed up is packaged, compressed, encrypted and partitioned; the target document is backed up; after backing up of the document, metadata of the target document and a Merkle tree of the target document used for auditing are added into a partition block; and the partition block is sent to the cloud server side, so the cloud server side can add the partition block to a partition block chain backup cloud based on the alliance chain. On the cloud server side, the method comprises the steps that the partition block chain backup cloud based on the alliance chain is established; the partition block sent by the client side is received, wherein the partition block comprises the metadata of the target document and the Merkle tree of the target document used for the auditing; and the partition block is added to the partition block chain backup cloud based on the alliance chain. According to the invention, resource sharing is achieved, and expenditures of conventional remote backup are saved.

Description

Technical field [0001] The invention relates to the technical field of data backup, in particular to a data security backup method based on an alliance chain, a client and a cloud server. Background technique [0002] In recent years, with the rapid development of computer-related software and hardware, especially the popularization of data collection equipment, more and more important data are collected. How to store these data for a long time and safely has become an increasingly urgent need for users. . Currently, various industries or institutions spend a lot of money to purchase storage devices to store these data. However, this storage solution has the risk of a single point of failure and data loss. Therefore, there is an urgent need to establish remote backups to ensure data security. However, the establishment of remote backups will bring more expensive overhead. [0003] At present, the third-party cloud storage solutions provided by the society cannot meet the require...
