Method and apparatus for sensing fingerprints

Various embodiments of the present invention is a technique for fingerprint identification method and apparatus using ultrasonic principles. Disclosed fingerprint method is a method for sensing a fingerprint for the object in an electronic device, an operation for receiving the acoustic signals reflected from the object; Operable to detect separately from the received acoustic signal at least one of the echo signal associated with the medium of the object to the receiving time; Based on at least one receive time of the echo signal with the detected it may include an operation of performing the detection of the fingerprint.
