The invention discloses an ocean data sharing method and system based on a block chain and federated learning, and a medium. The method comprises the following steps: establishing a block chain network according to a data sharing and weight allocation mechanism; converting a data sharing and weight distribution mechanism into a smart contract; in response to a federal learning request of a data user, performing learning retrieval in the block chain network; according to a learning retrieval result, sending retrieval data to a data user; determining a data provider according to the retrieval data; establishing a branch chain between the data user and the data provider according to the smart contract; according to the branch chains, the data provider obtains a training model from the data user for global model training; and performing parameter aggregation processing according to an intelligent contract in combination with a global model training result to obtain global model parameters. The method can solve the problems of dispersed ocean data, poor unified coordination and the like, further realizes ocean data sharing based on the block chain and federated learning, and can be widely applied to the technical field of block chains.
Description
technical field [0001] The present invention relates to the technical field of block chains, in particular to a method, system and medium for sharing marine data based on block chains and federated learning. Background technique [0002] With the country's increasing attention to marine resources and the improvement of marine observation capabilities, a large amount of marine-related data has gradually been produced. At present, multiple marine information centers and research departments have been established in the North Sea, East China Sea, and South China Sea. At the same time, with the rapid development of information technology, various departments and research institutions are actively developing electronic information business, and the demand for data sharing and communication among various departments and institutions is increasing day by day. And, at present, artificial intelligence technology has been developed and applied in many fields, and the comprehensive uti...
