(7) Output rusults:
When central processing unit in governor circuit module judges that comparing result is success flag code, perform step 7a); When judged result is failed authentication code, then perform step 7b);
7a) by user's Facial Features, the data information in data memory module, output to LCD display module; Information of voice prompt in data memory module is outputted to voice cue module;
7b) comparison failure information is outputted to voice cue module;
(8) register:
8a) operating personnel are by input operation module typing user Word message;
8b) eyes are placed in iris image acquiring window by user, and in acquisition module, optical anti-vibration is moved iris camera and obtain iris image in acquisition range; Iris image is converted to iris feature value code by the modulus conversion chip that optical anti-vibration is moved in iris camera;
8c) head is placed in human body appearance acquisition window by user, high pixel color camera collection user appearance image, and user's appearance image is converted to hexadecimal code;
(9) data are transmitted:
Central processing unit in governor circuit module judges the selection result of network channel in basic parameter, if when being wireless network card WiFi passage, performs step 9a); If when being Ethernet TCP/IP transmission channel, then perform step 9b); If when being mobile phone GPRS transmission passage, then perform step 9c);
9a) by the iris feature value code that iris capturing module obtains, be transferred to remote server by wireless network card WiFi transport module;
9b) by the iris feature value code that iris capturing module obtains, be transferred to remote server by Ethernet TCP/IP transport module;
9c) by the iris feature value code that iris capturing module obtains, be transferred to remote server by mobile phone GPRS transmission module;
(10) saving result:
Central processing unit in governor circuit module by user's Word message, iris feature value code and user's appearance Image Saving to data memory module.
