Researching on Cloud Service Architecture of Data Products

In order to make full use of data resources and enhance the transaction frequency of data trading market, we propose a cloud service architecture of data products, make data products available to the public as a cloud service, moving from a procurement system to a procurement data service. Data cloud services have several advantages. 1) It comprehensively integrates the data of government, enterprises and individuals, and promotes the integration and application of multiple data. 2) Data cloud services are inexpensive, easy to use and maintenance-free, which can greatly reduce the procurement costs for those who require data products. Since the issue of data right confirmation and data pricing is involved in the process of data circulation and fusion, we also propose a method of data right confirmation based on blockchain. This enables the transfer and trading of different rights to data by NFTs such as data ownership, data use right, and data revenue right. In addition, we analysis the data pricing ideas that should be adopted in the data trading market at different times and under different circumstances, and give the corresponding methods for calculating the price of data products. Finally, we introduced the actual application scenario of data products cloud service architecture.
