Abstract: A rapid identification method for fingerprint first provides a fingerprint identification apparatus having a fingerprint sensing area and divides the fingerprint sensing area into fingerprint sensing sub-regions. In a registration stage, the method performs fingerprint sensing for the entire fingerprint sensing area to obtain fingerprint image for a whole fingerprint sensing area, fingerprint minutiae and relevant locations for the fingerprint minutiae and then pre-stores those data. In an identification stage, the method performs fingerprint sensing on a part of the fingerprint sensing sub-regions for a user to be identified and detects fingerprint minutiae and relevant locations for the fingerprint minutiae in the part of the fingerprint sensing sub-regions. The method compares the fingerprint minutiae and relevant locations detected in the identification stage with respect to the corresponding fingerprint minutiae and relevant locations in the registration stage in order to determine whether the user can be granted with access right.

Abstract: A fingerprint identification apparatus includes a substrate, a second electrode layer, and a first electrode layer. The first electrode layer includes parallel first electrodes, and at least parts of the first electrodes have openings or dents. The second electrode layer includes parallel second electrodes and the second electrodes cross with the first electrodes on the substrate, where the openings or the dents are defined at the cross points from projected view. The second electrode is applied with transmitting signal and the corresponding electric field lines are received by the first electrode. The electric field lines detouring the edges of the first electrodes, or detouring the openings (or the dents) have induction with the finger close to or touching the first electrodes. The number of the effective electric field lines and the effective mutual capacitance changes can be increased to enhance the fingerprint sensing accuracy.
