Problems solved by technology

[0003] However, due to the inconsistent distribution of face data in various fields, such as ID photos of the public security system, face photos in complex scenes in the financial industry, and face photos in natural scenes in the security field, the data distribution is very different. The face recognition model trained on the face data set has poor generalization ability when applied to different application scenarios
For example, the face recognition model trained by the data set in the security field cannot be used in the financial and insurance industry
[0004] The collection of face data in various industries needs to abide by the relevant security regulations of personal information, making the face data collected by each of them unable to be used interoperably. Therefore, how to break the data silos and integrate face data from various fields to train a common face Recognition models to solve cross-industry face recognition problems are imminent

Abstract

The invention discloses a face recognition method based on knowledge federation, and relates to the technical field of computers. The method comprises the following steps: training a face recognitionmodel based on an obtained face data set, generating a face recognition gradient ciphertext through encryption according to an obtained face recognition model gradient, and sending the face recognition gradient ciphertext to a third-party terminal, so that the face recognition gradient ciphertext is subjected to decryption, knowledge federation and encryption to obtain a federation model parameterciphertext; and continuing to train the face recognition model based on the federated model parameters obtained by decryption, and performing face recognition according to the trained face recognition model. According to the method, it is guaranteed that original data do not leave the local, data privacy can be effectively protected, and the face recognition model obtained through federation training is high in universality and suitable for service scenes of mechanism terminals in different fields. The invention further discloses a face recognition device based on knowledge federation, electronic equipment, a storage medium and a system. The scale of the mechanism terminal in the system is not limited, and joining or quitting can be flexibly selected.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a face recognition method, device, equipment, medium and system based on knowledge federation. Background technique [0002] Face recognition technology is widely used in the fields of finance, insurance, retail, security, and public security. Face recognition technology used in various fields has cross-industry requirements. Compare the photo with the ID photo called from the public security system; or when deploying control in the security industry, it is also necessary to compare the face photo captured by the surveillance camera with the ID photo in the public security system. [0003] However, due to the inconsistent distribution of face data in various fields, such as ID photos of the public security system, face photos in complex scenes in the financial industry, and face photos in natural scenes in the security field, the data distribution is very different. Th...
