Embodiment Construction

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] A blockchain-based data security traceability method, such as figure 1 As shown, when the nodes on the chain write data, the written data is packaged and encrypted through the smart contract to obtain a packaged block. Among them, the smart contract performs AES encryption on the written data.

[0029] Record the relevant information of each packaged b...

Abstract

The invention relates to data tracing, the invention particularly relates to a data security tracing method based on a block chain. When data is written into the on-chain node, the written data is packaged and encrypted through the smart contract to obtain packed blocks, record related information of each packaging block, and establish a mapping relationship between the packaging block and an on-chain node associated storage block according to the related information; and the on-chain node needing data synchronization broadcasts a data synchronization request to the chain, synchronous data transmission is carried out through the on-chain node verified by the node, a data tracing request is broadcasted to the chain by an external node needing data tracing, it is decided whether the data tracing request is passed or not through voting of the on-chain node verified by the node, data is shared with the external node passed by the data tracing request by the on-chain node verified by the node, and data tracing is performed by the external node through a mapping relationship. According to the technical scheme provided by the invention, the defect that the cloud storage service cannot perform data security tracing can be effectively overcome.

Description

technical field [0001] The invention relates to data traceability, in particular to a blockchain-based data security traceability method. Background technique [0002] The blockchain is a distributed ledger system composed of a series of data blocks generated by cryptographic methods. The blockchain includes data blocks (blocks) and links (chains). A data block is a data structure that records transactions. Transaction records are verified transfer or mining records. Each data block contains all encrypted communication information data in the system within a certain period of time, which is used to verify the validity of the information and generate The next block; the link refers to the link relationship between each block and the next block, thus forming a blockchain. [0003] Currently, cloud storage servers are the best platform for large-scale data storage, thanks to their clustered operation and maintenance. However, the biggest obstacle hindering the development of ...
