Identity authentication method, identity authentication device, and identity authentication system

Abstract

Provided are an identity authentication method, an identity authentication device, and an identity authentication system. The identity authentication method may include transmitting an authentication signal and monitoring a server, detecting, based on the monitoring of the server, an update of a proximity state for an identity authentication device and an update of an authentication state for the identity authentication device, collecting, based on the proximity state for the identity authentication device corresponding to ON and the authentication state corresponding to OFF, authentication-purpose biometric data, and skipping, based on the proximity state for the identity authentication device corresponding to ON and the authentication state corresponding to ON, the collecting of the authentication-purpose biometric data.

Dependencies are inferred from the claim text.
