Fingerprint detection sensor and method of detecting fingerprint |
摘要 |
There is provided a fingerprint detection sensor and a method of detecting a fingerprint. The fingerprint detection sensor according to embodiments of the present invention includes a plurality of piezoelectric sensors arranged on a two-dimensional plane; and a fingerprint detection unit detecting a fingerprint by using ultrasonic signals discharged from the plurality of respective piezoelectric sensors, wherein the fingerprint detection unit determines whether the fingerprint is a forged fingerprint by detecting bloodstreams within a first region on the two-dimensional plane in which the ultrasonic signals discharged from the plurality of respective piezoelectric sensors overlap one another. |
