Description
Technical field
Expand the scheme for referring to hand vein recognition number of users the present invention relates to a kind of energy, belong to third generation biological identification technology neck
Domain.
Background technology
In the prior art, it is most of using card managing, it is more advanced to be verified using biotechnology
Management, and refer to hand vein recognition biotechnology and just developed in this field.Refer to one kind that hand vein recognition is hand vein recognition, belong to raw
Object identifies that it is exactly to obtain individual by hand vein recognition instrument first to refer to vein distribution map to refer to vein recognition system, is distributed from vein is referred to
Figure extracts characteristic value according to special alignment algorithm, and the image of finger, hand back vein is obtained by infrared C CD cameras, will be quiet
In computer systems, characteristic value is stored for the digital picture storage of arteries and veins.When vein compares, vein figure is taken in real time, and extraction is special
Value indicative, it is same to be stored in host medium sized vein with advanced filtering, image binaryzation, refinement means to digital image zooming-out feature
Characteristic value compares, and vein pattern is matched using complicated matching algorithm, so as to carry out identity authentication to individual, confirms body
Part.
When carrying out authentication with finger vein, the characteristics of image for referring to vein of acquisition refers to special existing for ability during live body
Sign.Within the system, the finger of non-living body is to cannot get vein image feature, thus None- identified, so as to also can not just make
It is false.When carrying out authentication with finger vein, acquisition is the vein image feature of finger interior rather than the image of finger surface
Feature.Thus, there is no any due to the damage of finger surface, abrasion, drying or the cognitive disorders brought such as overly wet.It is quiet with referring to
Arteries and veins carries out authentication, and when obtaining finger venous image, finger need not be contacted with equipment, gently one be put, you can complete identification.This
Kind of mode does not have antihygienic problem during hand contact arrangement and fingertip surface features may be replicated caused by safety ask
Topic, and the Psychological inadaptability for being taken as and examining object is avoided, while will not be because of None- identified after dirt contamination.Finger vena side
It is useful to be suitable for almost institute since the influence degree that vein is located at the external factor such as finger interior, temperature can be ignored for formula
Family.User's acceptance is good.Except without in addition to being contacted directly with scanner surface, the scanning process of this Noninvasive was both
It is simple again naturally, alleviating user due to worrying sanitation degree or using trouble and resisting psychology that may be present.Because have
The feature of the vivo identification of front, internal feature and contactless 3 aspects, it is ensured that the finger vein pattern of user is difficult quilt
It forges.So referring to vein recognition system safe class height, the place high particularly suitable for safety requirements uses.But the prior art
In there is problems it is to be solved：(1) belong to interior physiological characteristic, will not wear, it is more difficult to forge, there is very high security.
(2) blood vessel feature usually becomes apparent from, recognizable, and anti-interference is good.(3) non-contact measurement can be achieved, wholesomeness is good, is easy to
Receive for user.(4) it is not easy to be influenced by watch face scar or greasy dirt.More than technology has the drawback that：Collecting device has spy
Different requirement, design is relative complex, and manufacture is of high cost.
CPU card：Also referred to as smart card, with microprocessor CPU, storage unit and chip behaviour in the integrated circuit in card
Make system COS.CPU card equipped with COS is equivalent to a microcomputer, not only with data storage function, while has life
The functions such as order processing and data security protecting.CPU card is applicable to the multiple fields such as finance, insurance, traffic police, government industry, tool
There is the user's space big（It can store and refer to intravenous data）, reading speed is fast, supports the features such as one card for multiple uses, and passed through Chinese
People bank and the certification of national ministries and commissions.

Visitor carries out referring to vein image extraction and digitized processing, middle finger hand vein recognition follow the steps below：
The first step, training and projection refer to vein image, and the finger vein image of five candidates is obtained by the matching of grader, training
Obtained optimized image feature
Five candidates in second step, grader, which refer to, finds optimal test image in vein image：
A, all finger vein image training sets are loaded, it is corresponding to refer to vein with candidate；
B, refer to vein description using fusion and every deformation for referring to vein is extracted from training set；
C, extraction refers to the deformation of vein test image, is expressed as Dq；
D, refer to vein image with five candidates before with Dq to match, find matching key and count out
3rd step is counted out to determine verification criterion by matching key, and setting, which matches maximum finger vein descriptor of counting out, is
Most possible item by characteristic matching, obtains target and refers to vein image.
Then, by CPU card reader, the storage of vein pattern data is referred to CPU card, every time when identification, from CPU
It is read on card and refers to vein pattern data, in this way, the number of users of hand vein recognition can be referred to infinite expanding, it is ensured that refer to hand vein recognition
