Description

Service providing method and related device between data processors Technical Field The present application relates to the field of data security technologies, and in particular, to a method and an apparatus for providing services between data processors. Background The data become novel production elements, and accelerating the market configuration of perfect data elements is a key for promoting the development of digital high quality. How to share and use such data in compliance is the most critical research topic restricting such data as a new production factor in a data distribution scenario. In the related art, data is required to provide services, and for example, automotive data is applied to Usage-Based Insurance (UBI), an Insurance model in which UBI Insurance is priced according to actual Usage of an owner of an automobile, mainly priced by driving behavior and actual mileage. This is a more fair insurance pricing model for owners, and premium is low if owners open less steadily. For insurance companies, the premium is positively correlated with the risk probability, and the cost rate can be better controlled. From the perspective of social order, better driving habits of vehicle owners can be promoted through insurance pricing.
