Data sharing method and system, electronic equipment and storage medium

Abstract

The invention provides a data sharing method. The data sharing method comprises the steps of building a trust alliance block chain according to an Internet of Things application scene and an equipmentgeographic position, wherein the trust alliance block chain comprises a main chain and at least one slave chain, each slave chain corresponds to a sub-domain, and each sub-domain comprises a leader node; establishing a virtual slave chain on the trust alliance block chain; enabling a leader node in each sub-domain of the trust alliance block chain to designate a node in the sub-domain of the leader node as a federated learning node of the sub-domain, allocate a virtual identity to the federated learning node of the sub-domain, and join the virtual slave chain; and enabling each federated learning node to perform joint training of a neural network model by using the data generated in the sub-domain of the federated learning node, establishing the same federated learning model, and completing data sharing among the sub-domains. The invention further provides a data sharing system, electronic equipment and a storage medium.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of data processing, and in particular, to a data sharing method, system, electronic device, and storage medium. Background technique [0002] With the rapid development of various new distributed technologies, the concept of the Internet of Things has entered the public's field of vision. It connects devices scattered in different geographical locations and application scenarios through the Internet through sensor nodes, realizes data sharing and exchange, realizes the collaborative work of IoT devices and improves the performance and resource utilization of distributed systems. With the increase of IoT devices and application scenarios, the Internet of Things proposes the concept of "domains". The collaborative work of IoT devices is realized through data sharing between domains. How to realize the safe sharing of data in different domains has also become a hot spot in network...

Problems solved by technology

However, the above data sharing methods also completely expose the data while completing the data sharing, the data owner loses the control of the data, and the private data is also leaked along with the sharing process

In addition, with the proposal of data security laws such as the "Data Security Act" and "General Data Protection Regulation", the private data of IoT users is no longer allowed to be directly shared
