Hazardous chemical safety production digital block chain supervision platform

Abstract

The invention discloses a digital block chain supervision platform for hazardous chemical safety production, which includes: an acquisition layer for collecting production data information in the production process of a production enterprise, the acquisition device of the acquisition layer is set with a TEE trusted execution environment, and the collected The production data information is encrypted or hashed; the data layer is used to store the production data information collected by the acquisition layer through the alliance chain and store the hash of the data on the chain, and the acquisition layer communicates with the data layer; the blockchain is used for deployment The file chain contract, at the same time, the file is connected to the trusted environment and then encrypted and stored on the privacy computing server; the privacy computing platform is used to form the data metadata market of the file description information on the chain, and record the metadata information of the collected data , the data user applies for the right to use the data from the production enterprise. After authorization, the data user performs various applications on the privacy computing platform.

Description

technical field [0001] The invention relates to privacy computing technology, in particular to a digital block chain supervision platform for hazardous chemical safety production. Background technique [0002] The blockchain-based digital supervision platform currently mostly uses computer clients to synchronize data to the blockchain. After uploading to the blockchain, it can ensure that the data is decentralized, open, transparent and tamper-proof. In this implementation, the data does not have its own credibility before being uploaded to the chain. The data on the chain may be manually modified and adjusted by the platform, and the time may be out of order, or the order may be out of order. [0003] And at present, due to the lack of special blockchain chips and hardware, the authenticity of the data cannot be guaranteed before the data is uploaded to the chain, and it is difficult to achieve one-time collection of trusted data, permanent credibility, and multi-party use....

AI Technical Summary

Problems solved by technology

In this implementation, the data does not have its own credibility before being uploaded to the chain. The data on the chain may be manually modified and adjusted by the platform, and the time may be out of order, or the order may be out of order.

[0003] And at present, due to the lack of special blockchain chips and hardware, the authenticity of the data cannot be guaranteed before the data is uploaded to the chain, and it is difficult to achieve one-time collection of trusted data, permanent credibility, and multi-party use

For example, regulators and insurance companies have to make repeated visits, wasting a lot of manpower and material resources. At present, there is an urgent need for a reliable supervision platform, which can make data collection credible, unalterable, permanently credible, and private and safe when used by multiple parties.
