摘要： A method for sensing a fingerprint, comprising: receiving, by an electronic device, a sound wave signal that is reflected from an object; detecting at least one echo signal that is associated with the object for each reception period in a plurality of reception periods, wherein the at least one echo signal is detected based on the sound wave signal; and detecting the fingerprint based on the at least one echo signal.

摘要： An electronic device and an operating method thereof are provided. The electronic device includes a first processor, a second processor, a display, and a first sensor. The first processor receives an input through the first sensor while the display is in a deactivated state, and transmits the input to the second processor, when biometric data is detected in the input, and the second processor authenticates the biometric data included in the input, and activates the display if the authentication succeeds.
