Description
Technical field
The present invention relates to a kind of schemes that can expand vena metacarpea identification number of users, 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 vena metacarpea identification biotechnology has just developed in this field.Vena metacarpea identification is one kind of hand vein recognition, belongs to raw
Object identifies that palm vein identification system is exactly to obtain personal vena metacarpea distribution map by hand vein recognition instrument first, is distributed from vena metacarpea
Figure extracts characteristic value according to special alignment algorithm, and the image of palm, 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 vena metacarpea, acquisition be vena metacarpea characteristics of image, refer to during live body special existing for
Sign.Within the system, the palm 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 vena metacarpea, acquisition be vein image feature inside palm rather than palm surface image
Feature.Thus, there is no any due to the damage of palm surface, abrasion, drying or the cognitive disorders brought such as overly wet.It is quiet with slapping
Arteries and veins carries out authentication, and when obtaining palm vein image, palm 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 palm surface feature 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.Palm vein side
Since vein is located inside palm, the influence degree of the external factor such as temperature can be ignored formula, and it is useful to be suitable for almost institute
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 vena metacarpea feature of user is difficult quilt
It forges.So palm vein identification system safe class is high, 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,In cardIntegrated circuit in carry microprocessor CPU, storage unit and chipBehaviour Make systemCOS.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（Vena metacarpea data can be stored）, reading speed is fast, supports the features such as one card for multiple uses, and passed throughChinese People bankWith the certification of national ministries and commissions.
