Abstract
The utility model discloses a living fingerprint identifying device. Through the cross exposure of a fingerprint, a visible light image and a vein image of a finger are formed, and the cheating of a fake fingerprint and a fake finger film is prevented.
Description
Technical field
The utility model relates to a kind of living body finger print identification opening device, belongs to the fingerprint recognition field.
Background technology
Fingerprint recognition is owing to differentiating that performance is high, and is subject to more and more people's favor at aspects such as safety guard, access control and information managements.But these traditional fingerprint identification device limitation are larger, and touch-screen is generally optical profile type, by the mode of the surperficial optical imagery of fingerprint, easily by false fingerprint or the deception of false finger print.The means of these deception fingerprint identification devices are also utilized by unauthorized person gradually.
The utility model content
Utility model purpose: the utility model proposes a kind of living body finger print identification opening device, realize vivo identification, stop false fingerprint or the false deception that refers to film.
Technical scheme: the technical solution adopted in the utility model is a kind of living body finger print identification opening device, comprise topworks's drive plate, be arranged on the fingerprint identification module on topworks's drive plate, and the topworks that is connected to topworks's drive plate and carries out its instruction, described fingerprint identification module comprises the image acquisition sensor, communication interface, hummer and algorithm for recognizing fingerprint processing unit.Image acquisition device uses visible light source and infrared light supply to the synchronous crossover exposure of fingerprint, form fingerprint visible images and finger venous image, by the contrast of algorithm for recognizing fingerprint processing unit, comparing result is outputed to topworks's drive plate judge whether to meet unlocking condition again.
As further improvement of the utility model, described fingerprint identification module also comprises pilot lamp and the button that is positioned on the fingerprint identification module panel.Equipment on these panels can allow the user more clearly understand duty of the present utility model.
As further improvement of the utility model, fingerprint identification module can disassemble from topworks's drive plate, is convenient to safeguard.
Beneficial effect: the utility model forms the vein image of visible images and finger by the crossover exposure to finger print, has stopped false fingerprint and the false deception that refers to film.
Description of drawings
Fig. 1 is the structural representation of the utility model living body finger print identification opening device;
Fig. 2 is the structural representation of image acquisition sensor;
Fig. 3 is the structural representation of topworks's drive plate.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, the utility model living body finger print identification opening device is comprised of fingerprint identification module 1, topworks's drive plate 2 and topworks 3.Fingerprint identification module 1 includes image acquisition sensor 7 and communication interface 6.Also be provided with pilot lamp 4, button 5 on the panel of fingerprint identification module 1.Image acquisition sensor 7 when finger 12 is pressed in image acquisition device 7 surperficial, is positioned at 10 pairs of fingers 12 of its inner visible light source 11 and infrared light supply and carries out synchronous crossover exposure as shown in Figure 2, forms the fingerprint visible images and points 12 vein images.These image informations are by algorithm for recognizing fingerprint processing unit 13 contrast, and comparing result is outputed to single-chip microcomputer 8 in topworks's drive plate 2 by wired communication interface 6, as shown in Figure 3.If single-chip microcomputer 8 judgement unlocking conditions are set up, can start topworks 3 by motor-driven 9 at once.Topworks 3 is motor.
In other embodiment of the present utility model, communication interface 6 can also be used communication, and topworks 3 can also use electromagnet.
Claims (3)
