AUTHENTICATION PROCESSING DEVICE, AUTHENTICATION PROCESSING METHOD, TO-BE-AUTHENTICATED DEVICE, AND INFORMATION GENERATION METHOD

Abstract:

An authentication management device 20 and a to-be-authenticated device 30 share a learning model specific to the to-be-authenticated device in advance. An authentication requesting device 40 of an authentication requester transmits authentication data to the authentication management device 20 and the to-be-authenticated device 30. The authentication management device 20 inputs the authentication data to the learning model corresponding to the to-be-authenticated device 30 to generate authentication conversion data. The to-be-authenticated device 30 inputs the authentication data to the learning model and outputs to-be-authenticated side conversion data. The authentication requesting device 40 (or the authentication management device 20) can verify that the to-be-authenticated device is an authenticated device authenticated by the authentication management device when the authentication conversion data and the to-be-authenticated side conversion data are identical. Authentication accuracy can be secured simply by generating a new learning model specific to the to-be-authenticated device in case of learning model leak.
