The safety coefficient of fingerprint recognition is higher, optional in the present embodiment, and the fingerprint image of multiple fingerprint Identification sensor collections is mutual not
It is identical.That is, when fingerprint Identification sensor number is two, including the first fingerprint Identification sensor and the second fingerprint recognition pass
Sensor, wherein, the image of the image of first fingerprint and second fingerprint differs.Such as, for mobile phone unblock, the
One fingerprint can be left index finger fingerprint, and the second fingerprint can be right hand index fingerprint or left hand middle finger fingerprint, the present embodiment
In this is not limited.
In addition, for when fingerprint Identification sensor number is two, optional in the present embodiment, first fingerprint recognition
Sensor is capacitance type fingerprint identification sensor, and second fingerprint Identification sensor is optical fingerprint identification sensor.From
And avoid only a kind of fingerprint recognition mode, caused by the constant situation of fingerprint recognition accuracy, there are two kinds of different fingerprints
Accuracy, additionally it is possible to so that fingerprint recognition accuracy is different so that fingerprint recognition result match condition is different, finally influences fingerprint
The security of identification.

As a result send to fingerprint recognition result judge module 45；Likewise, the second fingerprint image acquisition module 421 carries out the second fingerprint image
As collection, then second fingerprint image is pre-processed by the second fingerprint image preprocessing module 422, the pretreatment bag
Gray processing, binaryzation etc. are included, this is not limited in the present embodiment.Then it is right by the second Finger print characteristic abstract module 423 again
Second fingerprint characteristic is extracted, then using the second fingerprint minutiae matching module 424 by the second fingerprint characteristic and the second fingerprint
The second fingerprint image to be prestored in storehouse 426 is matched, and matching result is sent to fingerprint recognition result judge module 45.Fingerprint
That recognition result judge module 45 sends the first fingerprint minutiae matching module 414 and the second fingerprint minutiae matching module 424
Comprehensive descision is carried out with result, obtains final fingerprint recognition result.
It should be noted that the first fingerprint image processing procedure can be carried out simultaneously with the second fingerprint image processing procedure,
Can also timesharing carry out, but handled using process chip, therefore, can be entered in the present embodiment using a process chip
Row handles different fingerprint images, so as to save the use of a process chip.
