Technical field
The utility model belongs to iris recognition and USB Key identity identifying technology field, and especially a kind of miniaturization only can realize the equipment of iris recognition and USB Key multimode authentication by a USB interface.
Background technology
Since ancient times, identity how to differentiate the people is a very problem of difficulty always, and after especially human society stepped into information society, individual identity presented digitizing and recessive notable feature, and this allows the identity of differentiating the people become difficult more.
From Authentication mechanism, traditional personal identification method just is converted into the identification problem things of some sign individual identities of identification, as key, certificate, user name, and password etc., the things of these sign individual identities is lost easily, forget and by counterfeit, that even more serious is owner and the counterfeiter that these traditional personal identification methods have no idea to distinguish real identify label thing at all, in case some unique people have obtained to identify the sign things of other people identity, also just have and the real identical power of owner, this is quite fearful thing, the serious safety that can jeopardize human society.
Along with the level of informatization of society is more and more higher, it is more and more obvious that the limitation of these traditional identity authentication modes and drawback show, owing to the mode of proof individual identity is lost or to crack the social danger that causes also increasing, traditional identity recognizing technology and method obviously can not satisfy the fast-developing needs of society, and human society is more and more urgent to high security, reliably automatic identity recognizing technology demand.How exactly the safety of the identity of identification society individuality, guarantee information becomes the crucial social concern that human information society must face and solve.
Just because of urgent social demand, various new automatic identity recognizing technologies emerge in an endless stream, but a lot of new identity recognizing technologies do not have limitation and drawback from solving the traditional identity recognition technology in essence yet, and only just improved technical threshold and the difficulty that cracks the traditional identity recognition technology, can not be from reaching the purpose of accurate identification individual identity in essence.
Biometrics identification technology is meant by computing technique and utilizes human individual's self physiology or behavioural characteristic to carry out individual identity a kind of new technology of identification automatically.These personal features comprise the biological characteristic of human bodies such as iris, fingerprint, face, sound, retina, and the action, the gait of walking, the behavioural characteristics such as dynamics of knocking keyboard of signature, are referred to as biological characteristic.Why biological characteristic can be used in individual identity identification, is because biological characteristic has ubiquity, all different uniqueness of each individuality that each individuality all has, and the stability that does not change with Individual Age.Compare with traditional personal identification method, based on the identity technology of biological characteristic do not have can forget or lose, be difficult for forging or stolen, carry and advantage such as can use whenever and wherever possible.
Biometrics identification technology is approved just gradually from solving the deficiency on the traditional identity recognition technology in essence.In recent years, along with the quick progress of computing technique and recognition technology, biometrics identification technology had obtained swift and violent development, in a lot of fields application had been arranged all, more and more demonstrated its huge commercial value and social value.Living things feature recognition will become the important way of following identification.
