Embodiment Construction

[0083] The fingerprint identification process is actually a matching process of fingerprint information. Specifically, it is to match the fingerprint features extracted from the fingerprint image collected on the spot with the fingerprint features in the pre-stored fingerprint template. Therefore, it is not difficult to see that the fingerprint feature is the key data in the process of fingerprint identification, and the information recorded in it directly affects the accuracy of the matching result. The present invention provides a kind of new fingerprint characteristic structure, and its specific structure is as follows:

[0084] feature header Fingerprint profile information Fingerprint Singularity Information Fingerprint details point information

[0085] Table 1

[0086] It can be seen from Table 1 that the fingerprint features provided by the present invention include four parts: feature head, contour feature, singular point feature and minutiae poin...

Abstract

The invention provides a fingerprint identification method aiming at default that present fingerprint identification system can not identify desquamate fingerprint, which relates to the fingerprint identification techinque. The method includes steps as follows: collecting fingerprint image and extracting the fingerprint characteristic, processing characteristic matching with the fingerprint characteristic and the fingerprint template; processing characteristic updating to the fingerprint template according with the fingerprint characteristic after successful matching. The invention also provides a fingerprint identification system. A technique scheme provided by the invention has merits as follows: processing characteristic updating to the latest fingerprint template according with successful matched fingerprint characteristic that can grasp the latest fingerprint characteristic information in the fingerprint desquamate process everywhen, and assorting using original fingerprint template can realize precise match in each phase of desquamate process and non-desquamate process. The scheme is realized by processing the fingerprint image and does not depend on sensor technique, so the scheme has low cost and is suitable for various fingerprint sensors.

Description

technical field [0001] The invention relates to fingerprint identification technology, more specifically, to a fingerprint identification method and a fingerprint identification system. Background technique [0002] Fingerprint identification technology provides people with a more accurate means of identification. figure 1 is a schematic diagram of the existing fingerprint identification process. Such as figure 1 As shown, the existing fingerprint identification process includes two parts: registration and online. In the enrollment part, the fingerprint of the enrolled user is captured by the sensor, and then the features are extracted and enrolled into the memory. In the online part, the fingerprint of the registrant is collected by the sensor, the feature is extracted and matched with the feature stored in the memory, and the matching result is output. The registration part often occurs in the parameter setting stage after the system is installed, and once the registra...
