Please refer to shown in Fig. 1 the biological characteristic synthesis recognition system block diagram that Fig. 1 provides for the utility model embodiment.

In the present embodiment, biological characteristic synthesis recognition system comprises linear transducer array 101, data processing equipment 102 and controller 103.

Described linear transducer array 101 is electrically connected with data processing equipment 102, for gathering successively finger print image, the back of the hand pore distributed image, the back of the hand lines image, finger blood oxygen saturation data, exports to data processing equipment 102.

In the present embodiment, described linear transducer array 101 comprises finger print acquisition module 1011, vision sensor 1012, optical scanner 1013 and the blood oxygen probe 1014 of arranging successively.Described finger print acquisition module 1011, vision sensor 1012, optical scanner 1013, blood oxygen probe 1014 are all connected with data processing equipment 102, for gathering successively fingerprint image, the back of the hand pore distributed image, the back of the hand lines image, finger blood oxygen saturation data, export to data processing equipment 102.

Described data processing equipment 102 is electrically connected with controller 103, for described fingerprint image and the authorized person's fingerprint image prestoring are compared, obtain fingerprint similarity, described the back of the hand pore distributed image and the back of the hand pore distributed image prestoring are compared, obtain pore distribution similarity, described the back of the hand lines image and the back of the hand lines image prestoring are compared, obtain lines similarity, to described finger blood oxygen saturation data analysis, obtain finger vascular distribution information, itself and the finger vascular distribution information that prestores are compared, obtain vascular distribution similarity, and according to described fingerprint similarity, pore distribution similarity, lines similarity and vascular distribution similarity are calculated comprehensive similarity, whether according to comprehensive similarity, differentiate personnel to be identified is authorized person, if, feedback " opening " signal is to controller 103, otherwise, feedback " not opening " signal is to controller 103.

In the present embodiment, described data processing equipment 102 comprises processor 1021 and storer 1022.Described processor 1021 and storer 1022, finger print acquisition module 1011, vision sensor 1012, optical scanner 1013, blood oxygen probe 1014, controller 103 is electrically connected, for authorized person's fingerprint image that fingerprint image and storer 1022 are prestored, compare, obtain fingerprint similarity, the back of the hand pore distributed image prestoring in described the back of the hand pore distributed image and storer 1022 is compared, obtain pore distribution similarity, the back of the hand lines image prestoring in described the back of the hand lines image and storer 1022 is compared, obtain lines similarity, to described finger blood oxygen saturation data analysis, obtain finger vascular distribution information, by prestoring in itself and storer 1022, finger vascular distribution information is compared, obtain vascular distribution similarity, and according to described fingerprint similarity, pore distribution similarity, lines similarity and vascular distribution similarity are calculated comprehensive similarity, whether according to comprehensive similarity, differentiate personnel to be identified is authorized person, if, feedback " opening " signal is to controller 103, otherwise, feedback " not opening " signal is to controller 103.When in fingerprint similarity, pore distribution similarity, lines similarity and vascular distribution similarity, arbitrary data are not less than 95%, judge that personnel not to be identified are authorized persons, when 100% of fingerprint similarity, pore distribution similarity, lines similarity and vascular distribution similarity remedied several products and be not more than 5%, judge that personnel not to be identified are authorized persons.Take fingerprint similarity as example, and 100% remedies number refers to: if fingerprint similarity is 70%, 100% of fingerprint similarity to remedy number be exactly 30%.
