Referring to Fig. 1, first embodiment of the invention provides a kind of fingerprint method for authenticating, including:
Step 101: measure the reflected spectrum data of target finger, and judge whether described reflected spectrum data meets live body
Reflected spectrum data feature；
Step 102: gather the finger print information of described target finger, and judge the finger print information of described target finger whether with
Preset authentication finger print information coupling；
Step 103: if described reflected spectrum data meets live body reflected spectrum data feature, and the finger of described target finger
Stricture of vagina information is mated with presetting authentication finger print information, then judge that described target finger is authenticated by fingerprint.
Specifically, when the light source of ambient light or known spectra is radiated on skin of living body, can be at skin of living body
Reflectance spectrum is formed under reflection.Under normal circumstances, due to the absorption to light of the hemoglobin in skin of living body skin corium
There are two significant absorption peaks in rate in the range of wavelength is 546.42-546.56nm (nanometer) and 576.26-575.45nm,
So that reflected spectrum data between the two absorption peak wavelength (such as: 559.48-559.72nm region) exist aobvious
The spike write.
Being appreciated that in one embodiment, described reflected spectrum data can present in graph form, then basis
The skin of living body absorption characteristics to light, the curve of described live body reflected spectrum data is in wave-length coverage 546.42-576.26nm
Between present the variation tendency of " W " type, thus form described live body reflected spectrum data feature.Specifically, described live body reflection
Spectroscopic data presents low ebb near said two absorption peak 546.42-546.56nm and 576.26-575.45nm, i.e. exists
Near said two absorption peak, major part light is absorbed by skin of living body, and the most a small amount of light is by reflection thus forms institute
State reflected spectrum data；And (such as: 559.48-559.72nm region) exist significantly between two described absorption peak wavelength
Spike, i.e. in the region that wavelength is 559.48-559.72nm, owing to skin of living body is relatively low to the absorbance of light, thus
Major part light is reflected back so that described radiation spectral data presents spike in this region.
It is appreciated that after measuring the reflected spectrum data of described target finger, by by this reflected spectrum data
Contrast with described live body reflected spectrum data feature, i.e. can determine whether whether described reflected spectrum data meets live body reflection light
Modal data feature, thus judge whether described target finger is live finger.If judging, described target finger is non-living body finger,
Show that described target finger may be by the finger that the material such as rubber, plasticine is imitated, then judge that described target finger is obstructed
Cross fingerprint authentication, to prevent fingerprint right discriminating system by malicious intrusions.If judging, described target finger is live finger, and described mesh
The finger print information of mark finger mates with presetting authentication finger print information, then judge that described target finger is authenticated by fingerprint.Can manage
Solving, described step 101 and described step 102 can perform with exchange sequence, it is also possible to perform, say, that the present embodiment simultaneously
Do not limit the execution sequence of described step 101 and described step 102.
In one embodiment, before the reflectance spectrum of described measurement target finger, described method also includes:
Triggering light source and send probing light, described probing light is anti-for being formed under the reflection of described target finger
Penetrate spectrum；
Trigger spectrum sensor and gather the reflection light that described probing light is formed under the reflection of described target finger
Spectrum；
The reflectance spectrum collecting described spectrum sensor processes, and generates reflected spectrum data.
Specifically, fingerprint authentication operations state can whether be in by proximity sensor detection target finger, it is possible to
Directly whether to be in fingerprint authentication operations state by fingerprint authentication module detection target finger.Wherein, target finger is in
Fingerprint authentication operations state refers to that the fingerprint tough of target finger is to state during fingerprint authentication button.When described target being detected
When finger is in fingerprint authentication operations state, then trigger light source send probing light, with by described probing light at described mesh
Form reflectance spectrum under the reflection of mark finger, and trigger the spectrum sensor described reflectance spectrum of collection, and then according to described
Reflectance spectrum generates corresponding reflected spectrum data.It is appreciated that by detecting that target finger is in fingerprint authentication operations
During state, trigger light source and send probing light, and trigger spectrum sensor collection reflectance spectrum, thus can authenticate at non-fingerprint
During mode of operation, described light source and spectrum sensor are set to resting state, such that it is able to reduce the merit of fingerprint right discriminating system
Consumption.
In the present embodiment, the described reflectance spectrum collecting described spectrum sensor processes, and generates reflection light
Modal data, can be to generate described reflected spectrum data by the intensity reflecting light calculating different wave length；Can also be to use
Reflectance spectrum is divided by default spectrum, and the result normalized obtained is obtained reflected spectrum data；Or, it is also possible to it is first
By reflectance spectrum and default spectral normalization, and normalized reflectance spectrum is utilized to be reflected divided by normalized default spectrum
Spectroscopic data.Wherein, described default spectrum can be ambient light spectrum.
In one embodiment, described method also includes:
The shell temperature of detection target finger, and judge whether described shell temperature is in preset temperature range；
If described shell temperature is in preset temperature range, and described reflected spectrum data meets live body reflectance spectrum number
According to feature, and the finger print information of described target finger mates with presetting authentication finger print information, then judge that described target finger leads to
Cross fingerprint authentication.
Specifically, it is also possible to judge whether described target finger is live body hands by the shell temperature of detection target finger
Refer to.Wherein, owing to the shell temperature of finger is usually less than the normal temperature of human body, therefore described preset temperature range can be slightly less than
Blood heat, such as, can be 32～33 degree.If detecting, the shell temperature of described target finger is in described default temperature
Within the scope of degree, then show that the temperature of described target finger meets the normal body surface temperature range of live finger.Be appreciated that by
It is easy to be faked in temperature data, only can not judge described target hands completely by the shell temperature of the described target finger of measurement
Refer to be live finger.It is in preset temperature range accordingly, it would be desirable to meet described shell temperature, and described reflected spectrum data
Meet live body reflected spectrum data feature, and the finger print information of described target finger authenticates, with presetting, the bar that finger print information mates
