Description
Technical field
The utility model relates to a kind of technical field utilizing biological characteristic to carry out identification and certification, particularly a kind ofly adopt finger vena identification and the residential quarters gate inhibition certification authority of wrist hand vein recognition in conjunction with certification.
Background technology
Along with the development of society, people are enjoyed to pay close attention in society safety problem.Social desirability can not be met completely based on traditional safety practices such as password, PIN (Personal Identification Number), magnetic card and keys.Such as along with the improvement of life, the raising of residential level makes us have higher requirement to the condition of living, due to the appearance of some extreme malignant events in society, make people more and more pay attention to the security system of residential quarters, intelligentized safety-protection system is more and more suggested and implements.And several large classes such as the safety management system of intelligent residential district also mainly comprises intrusion alarm system, system is registered in night watching, gate control system, closed-circuit TV monitoring system, house safety-protection system.And gate control system wherein manages intelligent dwelling important channel.Door control system can the discrepancy of controllers, can also controllers in building and the behavior of sensitizing range.At places such as doorway, building, elevators, control device is installed, such as: card reader, fingerprint reader, code keypad etc.Resident family wants to enter, and must have card or input correct password, or just can get permission to pass through by Special finger.Gate control system effectively can manage the open and close of door, and ensure that authorized person freely comes in and goes out, restricting unauthorized personnel enter.But above-mentioned gate control system still can not meet higher safe demand.
Under such background, people have invested biometrics identification technology sight---and the physiological characteristic utilizing human body intrinsic or behavioural characteristic are to carry out discriminating or the confirmation of identity.In prior art, common biometrics identification technology such as comprises fingerprint recognition, recognition of face etc., fingerprint recognition can be subject to a lot of restriction, the unexpected change of inevitable finger skin can affect the effect of fingerprint recognition, in addition, the fingerprint of groups of people or some colony, because feature is less, is therefore difficult to imaging, and there is finger wear or finger pollution etc. and cause degree of accuracy to be affected; In addition, the profile of wrist is very unstable, people can produce a lot of expression by the change of face, and in different viewing angle, the visual pattern of wrist also differs greatly, in addition, wrist identification is also by the impact of the many factors such as a lot of overcovers (such as mouth mask, sunglasses, hair, beard etc.), age of illumination condition (such as day and night, indoor and outdoors etc.), wrist.Difference between wrist identification Different Individual is little, and the structure of all wrists is all similar, and even the construction profile of wrist organ is all very similar, and it is disadvantageous for distinguishing human individual for utilizing wrist.
The finger vena identification technology that the basis of above-mentioned biometrics identification technology is developed starts to occur in recent years, and it is a kind of new biometrics identification technology, and it utilizes the vein distributed image in finger to carry out identification.During identification, contact is few even need not contact, and does not have fingertip surface features by the danger of third party's fraudulent copying; The feature of just existence when what system obtained is finger live body, the finger of non-living body can not get vein image feature, thus also just cannot to fake but hand back vein still may change along with age and physiological change, permanently not yet to be confirmed, although possibility is less, but still exist cannot successful registration registration possibility.Thus from current authentication method, there is certification degree not high, cause appearance that is dangerous or other problem.And the damage of finger surface, wearing and tearing, drying or too wet etc. also can bring cognitive disorders, make the precision of certification and accuracy be affected.
Do not consider in prior art in addition to point the impact that brings certification of angle, make verification process there is precision and accuracy is affected.
