Problems solved by technology

[0004] Therefore, for artificial intelligence technology, data circulation is required on the one hand, but security requirements severely restrict data circulation
In this case, the traditional data analysis mechanism cannot meet the regulatory requirements, and its essence is to change the data-centralized analysis technology into a data-distributed analysis technology

Abstract

The invention discloses a data sharing method and device based on federal data and federal service. The method comprises the following steps: receiving a model operation demand submitted by a data user; on the basis of the federated node capability database, generating an optimal decision result through matching according to model operation requirements; selecting a calculation model based on the optimal decision result, and sending the public key and the calculation model to a corresponding federated node; receiving a calculation result returned by the corresponding federated node, wherein the calculation result is obtained by calculation, through the federated node, based on the calculation model according to the federated data of the federated node and encryption through the public key; decrypting the result and returning to the data user; calculating the data revenue of each federated node participating in calculation, and providing the data revenue to a data provider; storing the calculation process data on an accounting node of the block chain; the data provider serving as a federal node. According to the invention, decision generation of demands of each data user is realized through a federation service mechanism, so that federation of services is realized.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data sharing method and device based on federated data and federated services. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Artificial intelligence (hereinafter referred to as AI) technology and applications have made breakthroughs in multiple fields and are rapidly changing the economy and lifestyle. Under the paradigm of deep learning, artificial intelligence has a huge demand for data. However, the current level of data sharing, trading and openness is seriously insufficient, which is becoming a bottleneck restricting the innovation and development of the industry. Most data owners are unwilling to open up their data, resulting in data islands. In addition to the...
