Privacy data credibility verification method based on block chain and privacy security calculation

Abstract

The invention discloses a privacy data credibility verification method based on a block chain and privacy security calculation. Secure and credible privacy data credibility verification is achieved through innovative combined use of the block chain and privacy security calculation technology. According to the method, on one hand, the authoritative department is willing to provide a credible data source, and on the other hand, the data transmission link, the data calculation link and the calculation conclusion link cannot be tampered, so that the electronic data is truly ensured to have the anti-counterfeiting performance comparable with that of a paper document. According to the invention, a safer, more credible and more automatic information credibility verification mode is created, which is particularly important for transaction scenes of bulk commodities such as house products involving a large amount of citizen privacy data. The application of the invention enables privacy data credibility verification scenes in various commercial activities to make real, credible and efficient business judgments based on the invention, and eliminates the possibility of fraud of house purchase qualification through data counterfeiting.

However, in the digital world, how to define the credibility of a data is a very complicated matter, which needs to satisfy the requirements of credible data sources, credible data transmission environment, credible data computing and its environment, credible data at the same time. Computational conclusions and other links. Even if authoritative departments can rely on public credibility to ensure credible data sources, in the current Internet environment, once the data is transmitted on the public network, it may be stolen and assigned; the data calculation process may also suffer from insufficient security of the environment. Attacks; even the ...
