Description
Technical field
The present invention relates to a kind of using the access control system for referring to hand vein recognition, belongs to third generation biological identification technology neck
Domain.
Background technique
Access control system can control the discrepancy of personnel, can with controllers in building and the behavior of sensitizing range simultaneously
The digitlization input-output control system of accurate recording and statistical management data.It mainly solve enterprises and institutions, school, community,
The safety problem of the important places such as office.Control device, such as access controller, password are installed on building doorway, elevator etc.
Keyboard etc..Resident is to entrance, it is necessary to have card or the correct password of input, or can just be approved to pass through by special bio password.Door
Taboo management system can effectively manage the open and close of door, guarantee that authorized person freely enters and leaves, and limitation unauthorized personnel enters.
Gate inhibition and security system are for protection staff and property safety, therefore system itself must be safe.Here institute
On the one hand the high security said refers to the natural quality or quasi- natural quality of product or system, it should be ensured that equipment, system operation
Safety and operator safety, such as: equipment and system itself want can high temperature-proof, low temperature, warm, smog, mould, drench with rain,
And energy radiation protection, anti-electromagnetic interference (Electro Magnetic Compatibility), protecting against shock, anticollision, dropproof etc., the operational safety of equipment and system
It further include fire prevention, anti-lightning strike, explosion-proof, protection against electric shock etc.；On the other hand, gate inhibition and security system should also have the function of anti-artificial destruction
Can, such as: there is tamper-proof protection shell, and there is dismantling-proof alarming, anti-short circuit and open.
In the prior art, 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.When with referring to that vein carries out authentication, acquisition refers to
The characteristics of image of vein, feature existing for ability when referring to living body.Within the system, the finger of non-living body is to cannot get vein image
Feature, thus can not identify, to also can not just fake.When with referring to that vein carries out authentication, acquisition is finger interior
Vein image feature, rather than the characteristics of image of finger surface.Thus, there is no any damages due to finger surface, mill
Damage, the dry or brings cognitive disorders such as overly wet.With referring to that vein carries out authentication, when acquisition finger venous image, finger 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
Fingertip surface features 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.Finger vena mode since vein is located at finger interior, 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 finger vein pattern of user is difficult to be forged.So refer to that vein recognition 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.
