Abstract: Disclosed is an electronic device. The electronic device according to an embodiment may include an ultrasonic sensor and a processor electrically connected to the ultrasonic sensor. The processor may be configured to obtain a noise signal at a periphery of the electronic device, via the ultrasonic sensor, to determine an attribute of a first ultrasonic signal oscillated by the ultrasonic sensor, based on the obtained noise signal, and to obtain fingerprint information based on the second ultrasonic signal obtained via the ultrasonic sensor and the determined attribute. Moreover, various embodiment found through the disclosure are possible.
