Abstract

The embodiment of the invention discloses a decentralized data verification processing method, device and system and a medium. The method comprises the following steps: receiving a data analysis request initiated by a data user; according to the data analysis request, reading data of at least one data unit required by analysis from one or more data centers to a trusted storage space of a trusted computing device; based on the data fingerprint of each data unit stored in the block chain network, verifying the read data, and if the verification is passed, confirming that the read data is valid;analyzing and processing the read data based on an analysis algorithm running in the trusted computing device according to the data analysis request to generate a processing result, and storing the processing result in the trusted storage space; and feeding back a processing result to the data user. According to the technical scheme provided by the embodiment of the invention, the data joint analysis processing can be realized, the credibility and safety of the data analysis processing process are ensured, and meanwhile, the calculation amount of data verification is reduced.

Description

technical field [0001] Embodiments of the present invention relate to data processing technologies, and in particular to a decentralized data verification processing method, device, system and medium. Background technique [0002] In the era of big data, all kinds of raw data and secondary processed data are intangible assets with economic value. Various types of enterprise users can provide some data themselves, but also need other enterprise users to share some data, so data centers have emerged. Various users provide their own data to the data center for payment or free trial by other users. [0003] In a data center, data is processed centrally. Not only can it be conveniently shared, but it can also perform joint analysis and processing based on multiple data, which greatly improves the ability and efficiency of data processing, and also provides richer data processing methods. [0004] However, the processing method of the data center also has certain defects: all d...
