The utility model discloses a finger vein authentication device with an organism finger recognition function, which comprises a finger placing seat. A complementary metal oxide semiconductors (CMOS) image sensor is arranged on the finger placing seat under the position of a finger pulp, the CMOS image sensor is connected with a control circuit, the finger placing seat is provided with a vein-irradiation infrared luminous light source set which can irradiate fingers placed on the finger placing seat, the finger placing seat is further provided with a finger epidermis irradiation light source set which can irradiate fingers placed on the finger placing seat from another angle, and the finger epidermis irradiation light source set is connected with the control circuit. Two or various different light sources are utilized to irradiate organism fingers, the image sensor is adopted to shoot discrepant images, and algorithm is used for judging whether fingers placed into the finger vein authentication device are organism fingers. Therefore, the problem that the finger vein authentication device can cause maloperations to non-organism fingers is resolved, the antifalsification of the finger vein authentication device is effectively enhanced, and the performance of the finger vein authentication device is improved.
Description
Technical field
The utility model belongs to and utilizes human body biological characteristics to carry out identification and authentication technology field, specifically is meant a kind of device that finger venous image authenticates of gathering.
Background technology
At present, Chang Yong bio-identification has technology such as fingerprint, palm, iris, face contour, sound, signature in the world, wherein, fingerprint recognition has conveniently, reliable and noninvasive advantage, be technical ripe relatively biological identification technology, be most widely used at present.But fingerprint recognition also has following deficiency: some people or colony's fingerprint characteristic seldom do not reach the requirement of filing; Part user can't authenticate because of finger wear; Each fingerprint that uses all can be left a trace, and has the possibility that is replicated utilization.At above many defectives, a kind of new biometric discrimination method-finger vena identification is suggested.
Finger vena identification is the new bio recognition technology that recent development is got up, and it is by extracting the method that finger vein features authenticates.Show through foreign study, finger vena identification refuse sincere and accuracy of system identification all is better than fingerprint identification technology.
Finger vena identification utilizes the characteristics of the infrared light of the haemoglobin absorption 700 ~ 1200nm wavelength region may in the blood, by finger is shone near infrared light, takes the vein pattern that refers to inside, and contrasts with the register information of registering in advance, and authentication in person thus.
Vena identification recognition device of the prior art judges whether to point the common method of putting into device to be had: 1, and soft-touch control or button.2, the infrared lamp correlation detects.Though more than two kinds of methods can both detect object and put device into, can't judge whether the object of putting into is the biosome finger, thereby cause the misoperation of device.The present invention has fundamentally got rid of the possibility that biosome is replicated forgery, has strengthened the antifalsification of finger vena identification dress effectively, has improved the performance of finger vein authentication device.
The utility model content
The utility model technical issues that need to address are to provide a kind of and judge whether the object of putting into device is the biosome finger, thereby prevent the finger vein authentication device of misoperation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the finger vein authentication device with biosome finger recognition function, include the finger placement rack, the finger placement rack is provided with cmos image sensor below finger abdomen position, cmos image sensor is connected to control circuit, described finger placement rack is provided with and can shines the irradiation vein infraluminescence light sources that places the finger on the finger placement rack, also be provided with the irradiation finger epidermis light sources that can place the finger on the finger placement rack from another angular illumination on the described finger placement rack, irradiation finger epidermis light sources is connected with control circuit.
Described cmos image sensor top is provided with infrared fileter.
Described irradiation vein infraluminescence light sources is arranged on the top that the finger placement rack is placed finger position, and described irradiation finger epidermis light sources is arranged on the below that the finger placement rack is placed finger position.
Described irradiation vein infraluminescence light sources is arranged on the top that the finger placement rack is placed finger position, and described irradiation finger epidermis light sources is arranged on the both sides that the finger placement rack is placed finger position.
Described irradiation vein infraluminescence light sources is arranged on the both sides that the finger placement rack is placed finger position, and described irradiation finger epidermis light sources is arranged on two side lower parts that the finger placement rack is placed finger position.
Owing to adopted above-mentioned structure, the utlity model has following beneficial effect: utilize two kinds or more of discrepant light source irradiation biosome fingers, photograph discrepant image by imageing sensor, whether utilize algorithm to judge to put finger vein authentication device into is the biosome finger, solved finger vein authentication device and the inorganic matter object has been produced the problem of misoperation, strengthen the antifalsification of finger vena identification dress effectively, improved the performance of finger vein authentication device.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Embodiment one
As shown in Figure 1, the utility model embodiment one described finger vein authentication device with biosome finger recognition function, include the finger placement rack, the finger placement rack is provided with cmos image sensor 105 below finger abdomen position, cmos image sensor 105 is connected to control circuit, and described cmos image sensor 105 tops are provided with infrared fileter 104.Described finger placement rack is provided with and can shines the irradiation vein infraluminescence light sources 101 that places the finger on the finger placement rack, also be provided with the irradiation finger epidermis light sources 103 that can place the finger 102 on the finger placement rack from another angular illumination on the described finger placement rack, irradiation finger epidermis light sources 103 is connected with control circuit.Described irradiation vein infraluminescence light sources 101 is arranged on the top that the finger placement rack is placed finger position, and described irradiation finger epidermis light sources 103 is arranged on the below that the finger placement rack is placed finger position.
As shown in Figure 2, its finger-image for photographing under the Different Light comprises image 201, the finger background image 202 that photographs opening infrared light supply and photograph, opens the image 203 that irradiation finger epidermis light sources photographs.Wherein, the image that cmos image sensor 105 obtained when the image that cmos image sensor 105 obtained when a was 101 irradiations of irradiation vein infraluminescence light sources, b were 103 irradiations of irradiation finger epidermis light sources.
When the utility model uses, after finger is put venous device into, open irradiation vein infraluminescence light sources 101, near infrared light sees through the finger epidermis, refraction in referring to, reflection is when light is mapped to finger internal jugular vein erythrocyte, part light is absorbed, and is placed on the cmos image sensor 105 that refers to below the abdomen and takes finger venous images.Close irradiation vein infraluminescence light sources 101, open irradiation finger epidermis light sources 103, irradiate light is to pointing the epidermis back reflection to cmos image sensor 105, cmos image sensor 105 compares and computing with the finger vein image after photographing finger epidermis image, judges according to algorithm whether put in the device is finger.
