Data sharing method, computer equipment applying same and readable storage medium

The invention discloses a data sharing method, computer equipment applying the same and a readable storage medium, and belongs to the technical field of data information security. According to the method, a blockchain technology and a federated learning technology are combined, a data security sharing model based on the blockchain and federated learning is constructed, and a data sharing basic process is designed; a working node selection algorithm based on a block chain and node working quality is designed by taking reliable federated learning as a target; a consensus method of a block chainis modified, an excitation mechanism consensus algorithm based on model training quality is designed, and the purposes of encouraging excellent work nodes to work, simplifying the consensus process and reducing the consensus cost are achieved. The differential privacy algorithm suitable for federated learning is selected by taking balance data security and model practicability as targets. According to the invention, the p
