Problems solved by technology

Even if this kind of fingerprint reader can identify authentic and fake fingerprints, its system complexity, high cost, and large size all run counter to the current trend of fingerprint readers tending to be small and thin
Except for special applications or occasions, this kind of microvascular fingerprint reader is not suitable for general electronic products
[0004] In addition, if the user's finger is injured and scars are left on the fingerprint, the conventional fingerprint reader is also prone to identification errors, so that the user cannot open the electronic product protected by the fingerprint reader, causing inconvenience to the user

Abstract

The invention discloses a fingerprint identification system and method that can detects the pore, the system includes fingerprint viewfinder device, pore detecting unit, fingerprint detecting unit and identifying unit. The fingerprint viewfinder device is used to acquisite a fingerprint image, the pore detecting unit is used to detect the pore data of the fingerprint image, the fingerprint detecting unit is used to detect a fingerprint line data. The identifying unit is any selection or combination of the pore data and fingerprint line data; it compares the fingerprint image with presorted fingerprint image. So, the accuracy of the fingerprint identification can be improved.

Description

technical field [0001] The present invention relates to a fingerprint identification system with detection capillaries and its method, in particular to a fingerprint identification system with capillary detection and its method which integrates capillary detection and fingerprint pattern detection. Background technique [0002] At present, fingerprint readers are gradually and widely used in electronic products to protect data in the electronic products. The principle of the conventional fingerprint reader is mainly to compare the captured fingerprint image with the pre-stored fingerprint image in the memory. However, such an identification method of simple fingerprint image comparison is easily deceived by forged fingerprints. For example, it is not difficult for a counterfeiter to reproduce a rubber fake fingerprint from a stolen fingerprint image. In the two fingerprint images shown in Fig. 1A and Fig. 1B, one of them is a fake fingerprint, and the other is a real livin...
