Block chain data supervision method and system based on knowledge graph and computer equipment

Abstract

The invention discloses a block chain data supervision method and system based on a knowledge graph and computer equipment, and the method comprises the steps: carrying out knowledge modeling, and defining business entities, relationships and attributes according to different block chain business meanings and data types; knowledge extraction: extracting business entities, relationships and attribute data in each chain; knowledge fusion: carrying out entity combination and entity attribute and relationship combination on data in different block chains; knowledge storage: storing the block chain data into a graph database to form a block chain data knowledge graph; and knowledge calculation: defining a data supervision rule and a corresponding reasoning logic based on the block chain data knowledge graph, and finally obtaining a reasoning conclusion based on the supervision rule by adopting knowledge reasoning and graph mining methods so as to achieve the purpose of data supervision. The universal block chain data supervision method and system are provided by adopting the knowledge graph technology, the supervision rule can be flexibly configured, the purpose of block chain data supervision is achieved, and the security of block chain business is improved.

Description

technical field [0001] The invention belongs to the technical fields of computer systems and block chains, and in particular relates to a block chain data supervision method, system and computer equipment based on knowledge graphs. Background technique [0002] Blockchain is a method of connecting data blocks sequentially in chronological order and combining them into a chained data structure, which is stored in a decentralized manner among all participants, and uses cryptography to ensure that data cannot be tampered with, cannot be forged, and is traceable Distributed data ledger technology. Through the application of blockchain technology, the integrity and reliability of information can be guaranteed, and the trust and security problems existing in the process of information interaction can be effectively solved. The financial industry has the characteristics of high trust costs and collaboration costs for participants, and high requirements for security and completenes...

Problems solved by technology

In the blockchain system, data is written or read by all peer nodes. Therefore, it is impossible to prevent illegal and illegal information from being written into the blockchain. For the blockchain system applied to financial scenarios, the chain involves user assets , it is also necessary to review the asset data on the chain

In addition, since the data on the blockchain cannot be easily searched, counted and analyzed like relational databases, the blockchain system is not easy to review and supervise information.
