Legal Model Construction Approach of Big Data Transaction Management in the Digital Information Perspective

Abstract

This paper constructs and applies the legal model of transaction management in the digital information perspective based on the approach of big data. To solve the problem, it is necessary to integrate various legal tools, construct an idealized legal model of big data transaction management, conduct interprofessional and interdisciplinary research on the big data transaction management problems that are difficult to be regulated by the existing legal norms, and selectively design and arrange the corresponding system, to provide the digital regulatory tools for the operation of the digital economy and promote the scientific and standardized development of the digital economy. Based on the decentralized blockchain platform, sealed bidding is used to achieve information isolation among nonconspiratorial data buyers, and through the big data auction algorithm, the purpose of the conspirators cannot be achieved and anticomplicity is realized. The model is based on smart contracts and combined with auction theory to achieve anticollision in the process of big data auctions. Based on the model, we construct an anticomplicity big data auction mechanism and dissect the big data auction algorithm. The correctness of the model and algorithm is demonstrated through simulation. After the data is hosted, the data will be completely owned by the big data trading center. In the data transaction process, the big data transaction center provides data resource information to data buyers, so that data buyers can select the required data. Second is the construction of a multilevel regulatory system in the administrative supervision of the construction of the central national security leading institutions led by the interregional collaborative regulatory system and in the industry self-regulatory supervision of the implementation of the data trading platform data trading supervision obligations. The balance between the development of the data trading industry and data trading security is comprehensively maintained from multiple perspectives of legislation and law enforcement.
