Abstract

The invention discloses a sample matching method and device and a readable storage medium. The sample matching method comprises the following steps: initiating an intersection task to a second deviceassociated with the first device, receiving a public key corresponding to the intersection task sent by the second device, based on the public key, obtaining a first intermediate result correspondingto the first device, judging whether a preset cache mode is used or not; if the preset cache mode is used, obtaining a second intermediate result based on the preset cache mode, so as to execute a preset sample matching process based on the first intermediate result and the second intermediate result, receiving the second intermediate result sent by the second device if the preset cache mode is not used, and executing the preset sample matching process based on the first intermediate result and the second intermediate result. The technical problem of low sample matching efficiency in the priorart is solved.

Description

technical field [0001] The present application relates to the field of machine learning technology of financial technology (Fintech), and in particular, to a sample matching method, device and readable storage medium. Background technique [0002] With the continuous development of financial technology, especially Internet technology finance, more and more technologies (such as distributed, blockchain, artificial intelligence, etc.) are applied in the financial field, but the financial industry also puts forward higher requirements for technology. Requirements, such as the distribution of corresponding to-do items in the financial industry, also have higher requirements. [0003] With the continuous development of computer software and artificial intelligence, the application of federated learning is becoming more and more extensive. Before federated learning, it is usually necessary to match the samples of each participant in federated learning. At present, based on RSA enc...
