Fig. 1 is the functional-block diagram of the identification authentication system of multi-modal combination described in the utility model;
Fig. 2 is one of the identification authentication system of a multi-modal combination described in the utility model specific embodiment.
Embodiment
Come the identification authentication system of multi-modal combination described in the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Consult shown in Fig. 1, the identification authentication system of multi-modal combination described in the utility model is a kind of with fingerprint with refer to that two kinds of biological characteristics of vein realize what identity was differentiated in conjunction with going, and antifalsification height, and the identification authentication system that degree of safety and accuracy rate are high comprises fingerprint and the data acquisition module 10 that refers to that vein image is gathered, to gathering the fingerprint that comes and referring to the pretreatment module 20 that the vein data are handled, the storage fingerprint and refer to the vein related data storage unit 30 and will be from data acquisition module 10 that send and through pretreated comprise by discriminating person's fingerprint and the assemblage characteristic data that refer to vein be stored in the fingerprint in the memory module 30 and refer to the authentication module 40 that vein assemblage characteristic data are compared.
Wherein, described data acquisition module 10 comprises the fingerprint of gathering and refers to that vein carries out the image-generating unit 100 of imaging and the collecting unit 101 that fingerprint image and finger vein image are gathered, described pretreatment module 20 mainly is by to comprising fingerprint image and referring to that the signal of vein image cuts, makes up stack, filtering enhancing and feature point extraction, comprises fingerprint and the assemblage characteristic data that refer to two kinds of biological characteristics of vein thereby form.
In addition, comprise in the described image-generating unit 100 fingerprint imaging part 1000 and 1,001 two imaging moieties of finger vein imaging part, the image of fingerprint image and finger vein all can adopt optical prism to be embodied as picture, wherein, described fingerprint image can form in the interference of prism surface and through inner full-reflection by streakline, and described finger vein image then is finger to be placed optical prism and utilize the exciting light transmission to form.
Described collecting unit 101 includes imageing sensor 1010, photoelectric commutator 1011 and analog to digital converter 1012, in the utility model, this collecting unit 101 is for adopting a video camera, so that gather fingerprint image simultaneously and refer to vein image, at this moment, fingerprint is a plane with the object plane and the exit facet that refer to vein image.Described imageing sensor 1010 is for adopting high resolving power face formation imageing sensor, it is for gathering simultaneously fingerprint image and finger vein image, described photoelectric commutator 1011 carries out opto-electronic conversion and exports to analog to digital converter 1012 with the form of analog electrical signal for the image that imageing sensor 1010 is gathered, analog to digital converter 1012 is converted to digital signal with this analog electrical signal, and last and employing high speed USB communication mode comprises fingerprint image with number and refers to that the digital electric signal of vein image is transferred to pretreatment module 20.
