Abstract

The present application discloses a federated learning data anti-tampering monitoring method and related devices. The method includes: sending the training configuration data to the target device obtained after screening through the server, so that the target device performs local training according to the training configuration data and obtains the training result ;Use the preset hash algorithm to calculate the first hash value of the training result through the target device, and at the same time send the first hash value to the blockchain, and send the training result to the server, and the blockchain communicates with the server through the preset smart contract Establish a connection with the target device; verify the result through the server according to the received training result and the first hash value obtained from the blockchain, and if the verification is passed, it can be judged that the training result received by the server has not been tampered with. This application solves the technical problem that the existing federated learning lacks a monitoring mechanism for tampered transmission data, which makes the server unable to judge the credibility of the data and affects the update effect of the global model.

Description

technical field [0001] The present application relates to the technical field of federated learning, and in particular to a tamper-proof monitoring method and related devices for federated learning data. Background technique [0002] Blockchain is a shared database and a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The data or information stored in the blockchain has the characteristics of "tamper-proof", "traceable", "open and transparent", and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation and created a reliable "cooperation" mechanism. The smart contract is an end code that is stored on the block and can run in the blockchain. It can be simply understood as an automatically executable script that runs on the blockchain framework without third-party control; therefore, it can be executed accord...
