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.

Abstract: Disclosed are a biometric authentication device and a fingerprint authentication device including the same. The biometric authentication device includes a clock generator that generates a clock signal, an authentication signal generator that generates an authentication signal based on the clock signal, a transmission electrode that transmits the authentication signal to a contact body, a reception electrode that receives a channel pass signal in which the authentication signal passes through a channel of the contact body, and a biometric authenticator that restores the channel pass signal and compares the restored channel pass signal with the authentication signal to generate a biometric authentication signal indicating whether the contact body is a biological tissue. According to the present disclosure, it is possible to improve the security of a fingerprint authentication device.
