The anti-pseudo problem of certificate is a difficult problem that is perplexing people and government always.For many important certificates,, be its topmost function to the authentication that holds as identity document, credit card, passport, confidential departments' pass etc.Because these certificates are for the importance of individual and society, also because the pseudo-technology for making of present certificate is more and more superb, false proof, anti-the usurping of these certificates also becomes more and more urgent problem.

Existing IC-card identity document recognition device, information that can only reading and writing IC card or by fingerprint picked-up instrument, computer storage recognition system is finished the process of gathering fingerprint, fingerprint contrast respectively.Word messages such as image informations such as these devices not only take up room big, and energy resource consumption is many, and can not carry out reading and writing IC card I.D., collection fingerprint, fingerprint contrast simultaneously in a device, display photos and name.

The purpose of this utility model is for a kind of all multi-functional Artificial Intelligence Instruments of Word message such as read-write intellective IC card I.D., collection fingerprint, fingerprint comparison, display photos image information and name that integrate are provided, make it function that possesses strong computing, control, communication and system response time fast, power saving space-efficient feature.

The utility model designs in order to discern to deposit through encrypting with the IC-card identity document of the many pieces of fingerprint characteristic datas, a photos and the relevant Word message that compress.It comprises operation keyboard, LCD, it is characterized in that, it also comprises finger-printer reader, carrying out fingerprint characteristic for one extracts, fingerprint is automatically compared, data decryption and decompression, the CPU (central processing unit) of function such as logic control and data communication, the intellective IC card read write line, main equipment board, communication interface, described CPU (central processing unit) is by 32 embedded type CPU chips, the data memory chipset, the program memory chip group, devices such as sequential logic control chip group are formed, described communication interface is the proprietary extensions interface board, it is an integrated interface circuit that drives the CMOS fingerprint sensor, ECP parallel communication interface, one connects the serial communication interface that MODEM is connected into wide area network, a serial communication interface of forming LAN (Local Area Network), an intellective IC card read-write jack interface, a status indicator lamp driving interface, described main equipment board is by the AC/DC power module, the keyboard decoding module, encrypting module is formed.

The used finger-printer reader of the utility model is CMOS fingerprint sensor or optical fingerprint sensor (containing the image pick-up card that meets the PC/104 standard).

Hardware configuration of the present utility model be decrypted, decompress and carry out fingerprint automatically identification, display photos and the software of testing Word messages such as card result match, constitute a powerful intelligent IC-card identity document identification instrument by these software and hardware functional modules.This instrument has the feature of fast (it is fast that instrument is tested card speed) two provinces of three strongest ones' (computing, control, communication function are strong) (power saving-energy-conservation, save space-volume little).Can be applicable to occasion that various needs accurately discern identity as public security, customs, bank, post office, examination hall, hotels and other places, the true and false of checking IC-card fingerprint identification card spare.This is thoroughly to solve resident identification card, temporary residency card, and officer's identity card, driver's license, personalized identity documents such as passport thorough false proof provides a kind of realistic plan.

The utility model also possesses other function:

Can be used as fingerprint collecting, feature extraction and the information encryption of making intelligent anti-counterfeiting IC-card identity document, the equipment of information coding; Carry out communication by parallel port and scanner, the first-class image input device of shooting, the function that realizes that image input and compression are handled can be provided; The record of breaking rules and regulations, inspection record, training record, family planning record etc. can be write in the high-capacity intelligent IC-card, be record and the service of inquiry holder personal information.Can pass through blacklist (wanted criminal, the suspect) inquiry (with fingerprint mode, name mode, photo mode and personal identification number PIN mode etc.) of LAN (Local Area Network), wide area network realization variety of way.
