Block chain-based trusted data space management method and system

Abstract

The invention discloses a trusted data space management method and system based on a block chain, and relates to the technical field related to data security, and the method comprises the steps: constructing a block chain network of a trusted data space; obtaining first access information of the trusted data space; introducing an access behavior credibility evaluation function to evaluate and analyze the first access information to obtain a first access credibility; if the first access trust degree meets a preset trust degree threshold value, extracting a first access demand; and retrieving the first access demand in the trusted data space based on the intelligent retrieval contract to obtain a first retrieval result. The technical problems that in the prior art, the data credibility is difficult to guarantee, the data islanding phenomenon is serious, and consequently the data access safety is insufficient and the data retrieval efficiency is low are solved, and the technical effect of improving the data access safety and the data retrieval efficiency is achieved.
