Description
Technical field
The present invention relates to a kind of guest systems identified using vena metacarpea, belong to third generation technical field of biometric identification.
Background technique
Guest machine, guest system are a collection computer technology, Radio Frequency Identification Technology, fingerprint bio identification, touch screen hand
Writing technology, Text region (OCR) technology, thermal printing technique, barcode technology, digital photographing technique, automatic accreditation technology, hardware
Encryption technology, network technology are in one, comprehensively certificate information, image information and the disengaging of record, preservation visitor's visiting personnel
Information simultaneously provides convenient and fast multimode inquiry to visiting data, current hand filling is entered and left registration management, telephone counseling is interviewed
The traditional approach such as people are changed into high-tech computerization, digitized processing, and it is long to eliminate hand-written registration fill in the time, and information lacks
Lose false more, not easy to maintain, various drawbacks such as information inquiry difficulty.Also known as " visitor registers safety management system to guest machine automatically
System ".It replaces hand-written visiting registration, using Modernized Information Technology, is truly realized personnel, certificate, photo three unification.
In the prior art, 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.When carrying out authentication with vena metacarpea, acquisition is the palm
The characteristics of image of vein, feature existing for ability when referring to living body.Within the system, the palm of non-living body is to cannot get vein image
Feature, thus can not identify, to also can not just fake.When carrying out authentication with vena metacarpea, acquisition is inside palm
Vein image feature, rather than the characteristics of image of palm surface.Thus, there is no any damages due to palm surface, mill
Damage, the dry or brings cognitive disorders such as overly wet.Carry out authentication with vena metacarpea, when obtaining palm vein image, palm without
It must contact with equipment, gently one put, identification can be completed.Antihygienic problem when this mode does not have a hand contact arrangement and
Palm surface feature may be replicated brought safety problem, and avoid the Psychological inadaptability for being taken as and examining object, simultaneously
It will not be because that can not be identified after dirt contamination.Palm vein mode since vein is located inside palm, the external factor such as temperature
Influence degree can be ignored, and be suitable for almost all users.User's acceptance is good.In addition to without occurring with scanner surface
Other than directly contacting, the scanning process of this Noninvasive not only it is simple again naturally, alleviate user due to worry sanitation degree or
Using trouble and resisting psychology that may be present.Because having the vivo identification of front, internal feature and contactless 3 aspects
Feature, it is ensured that the vena metacarpea feature of user is difficult to be forged.So palm vein identification system security level is high, it is especially suitable
It is used together in the high place of safety requirements.It but there is problems in the prior art to be solved: (1) belonging to Nei Shenglite
Sign, will not wear, it is more difficult to forge, have very high security.(2) blood vessel feature usually becomes apparent from, recognizable, anti-interference
It is good.(3) non-contact measurement can be achieved, wholesomeness is good, is easy to as user's receiving.(4) not vulnerable to watch face scar or greasy dirt
It influences.The above technology has the drawback that: acquisition equipment has particular/special requirement, designs relative complex, manufacturing cost height.
Summary of the invention
The purpose of the present invention.
The present invention is exactly the difference for employee and visitor, allows employee using vena metacarpea, and visitor is checked card using identity card, and
