    Abstract: Disclosed are a biometric template-based authentication electronic device and an operating method thereof. The electronic device includes a memory, a transmitter that transmits a chirp signal, of which a frequency is changed, to a user, a receiver that obtains a biometric channel response signal, which responds to the transmitted chirp signal, from the user, and at least one processor that executes a biometric template authentication module based on machine learning. When executing the biometric template authentication module, the processor obtains a feature signal from the obtained biometric channel response signal, generates a biometric template from the obtained feature signal, performs the machine learning such that identification information of the user is inferred from the generated biometric template, and authenticates the user based on the result of the machine learning.
