Embodiment Construction

[0025] Such as figure 1 As shown, for the attribute encryption service platform, user B can adopt a specific access control strategy S for a certain transaction information on the chain (for example, S1 and (S2 or S3), where S1, S2, and S3 are all attributes) It is encrypted and verified by a decentralized AA node. For a user A who wants to access some data, he applies for a unique user key from the AA node based on his own attributes. If his own attribute set satisfies a specific access control policy, then his own key can decrypt it . For example, in the figure, if user A has attributes S1 and S2, then its key can decrypt the data D1 encrypted with S.

[0026] figure 2 It is a schematic diagram of the hazardous chemical supervision system proposed by the present invention. Enterprise nodes and supervisory nodes jointly maintain the underlying chain. The system contract layer is responsible for encapsulating some functions of the chain for calls by upper-layer contracts...

Abstract

The invention belongs to the technical field of dangerous goods supervision, and particularly relates to a dangerous chemical supervision system based on a block chain. The invention discloses a dangerous chemical supervision system based on thea block chain. The dangerous chemical supervision system comprises enterprise nodes, supervision nodes, a bottom layer chain for storing information, a decentralized attribute password service and a system contract layer for executing main supervision functions, wherein the enterprise nodes are related enterprises participating in the links of dangerouschemical production, transaction, transportation and the like; the supervision node is composed of related supervision departments, and the system binds the flow of dangerous chemicals with an enterprise through the traceability and unchangeable characteristics of a block chain, thereby achieving the whole-process supervision of the production, circulation and use of dangerous chemicals. Besides,the introduction of the decentralized attribute password enables the system to realize refined authority management and control, and each supervision department only acquires necessary data, therebyreducing the risk of data leakage and abuse.

Description

technical field [0001] The invention belongs to the technical field of dangerous goods supervision, and in particular relates to a blockchain-based hazardous chemicals supervision system. Background technique [0002] At present, there are eight departments in my country that supervise hazardous chemicals, namely: safety production supervision and management department, quality supervision, inspection and quarantine department, environmental protection department, transportation department, health department, public security department, industry and commerce department Administrative management department, postal management department. The coordination between different departments is not smooth, the exchange of information is not very timely, and the law enforcement process is not strict enough. [0003] At the same time, in the process of hazardous chemicals management, various enterprises choose to conceal or falsely report information due to fear of their own data leakag...
