Description
Technical field
The utility model relates to a kind of technical field utilizing biological characteristic to carry out identification and certification, particularly the authenticate device that combines with facial hand vein recognition of finger vena identification.
Background technology
Along with the development of society, people are enjoyed to pay close attention in society information security issue.Inherently safe and individual privacy protection become the hot issue in these epoch.Social desirability can not be met completely based on traditional safety practices such as password, PIN (Personal Identification Number), magnetic card and keys.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 face is very unstable, people can produce a lot of expression by the change of face, and in different viewing angle, the visual pattern of face also differs greatly, in addition, face recognition 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.), face.Difference between face recognition Different Individual is little, and the structure of all faces is all similar, and even the construction profile of face organ is all very similar, and it is disadvantageous for distinguishing human individual for utilization face.
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.In addition, the finger vena blood of women is less than the male sex under normal circumstances, and this vein pattern that vein image collected is comprised is less and contrast is lower.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.
Summary of the invention
The utility model is intended to solve above-mentioned technical matters, proposes a kind ofly to have the shortcoming overcoming current biometrics identification technology, makes organism authentication apparatus and authentication method can have higher antifalsification and practicality, and improves the precision of certification.The utility model, in order to solve the problems of the technologies described above, can be realized by following mode.
