On authentication, the data is decompressed and deencrypted by IC card reader to obtain the data stream about the face, which is input to display to show the face on screen, so attaining antiforge purpose.
Description
Identification card-contact IC card) etc. the present invention relates to a kind ofly utilize facial image (Integrated Circuit Card, the international standard generic name is: the method for anti-fake certificate is carried out in the field to IC-card.
Widespread use in finance and non-financial field is with universal along with electron currency and IC-card, people enjoyment hold wander through the world in, also but the heart in case IC-card stolen or lose or be forged, hold this and stick into row clearing or other behavior producing other people inevitably, bring a loss economic and that name is transcribed not only for the owner of card, also will bring loss on economy and the fame to card sending mechanism.Cause above-mentioned reason to be: when IC-card and application, card holder's IC-card and I.D. (or passport) can only be checked by the unit of swiping the card or mechanism, and do not check and differentiate human body information between the IC-card owner and the holder, in case IC-card is stolen or loss, the thief or the person of picking up can hold the behavior of swiping the card that this sticks into aspects such as capable consumption, drawing or clearing by I.D. or the passport forged.On the other hand, only the method by additional human body head portrait photo on certificate or card prevents that puppet from emitting or when forging, often can't be effectively false proof because this certificate or the photo that blocks are replaced easily or are forged.So be necessary to propose a kind of passing through: to human body information, as utilize digital camera equipment that man face image acquiring is become bitstream, compressed again and encryption adult face image password flows and it is stored in the IC-card; By IC-card deciphering back output or show, differentiate whether shown facial image is consistent with the person's that holds the IC-card facial image, the method for coming IC-card is carried out anti-fake certificate during authentication by checking.
Purpose of the present invention: after facial image numberization, deposit in the IC-card, as depicted in figs. 1 and 2 after compressed and encryption adult face image password flows with the IC-card applicant; When the IC-card holder consumes, withdraws deposit or during behavior such as clearing, the unit of swiping the card or mechanism not only examine the former identification information of IC-card and I.D. (or passport) etc., also will further differentiate the consistance of the facial image of depositing in card holder and the IC-card, thereby reach the purpose of the anti-fake certificate of IC-card.In the present invention, adopt modern Image Data Compression treatment technology that the compression of facial image bitstream is processed into the compression of images bitstream, deposit in the IC-card only to use less than 2 K bytes of memory amounts, not only read the possessory former identifying information of IC-card when swiping the card, also will read this and block possessory human face image information, and make card holder and this block possessory facial image and also must reach unification.For the discriminating authentication of the facial image of depositing in card holder's facial image and the IC-card, can differentiate by human eye by the person of swiping the card of the unit of swiping the card and check.Because the ability of human identification facial image just possesses when the juvenile, if the relevant personnel of the unit of swiping the card or mechanism are further trained, just is easy to improve the accurate discrimination of facial image.Another important part of the present invention also is the encryption to the facial image bitstream, can adopt DSE arithmetic also can adopt the data encryption algorithm of asymmetric cryptosystem, and the facial image key stream after encryption deposited in the IC-card, again it is decrypted when swiping the card, thereby makes that institute's facial image number of depositing can not be by imitated in the IC-card.In the present invention, needn't transmit because the facial image bitstream deposits in the IC-card, therefore, the network system of IC-card needn't be done big change, thereby has protected the original investment of card sending mechanism and realized simple, easy row.When swiping the card, the deciphering of facial image is finished by IC-card self with output, so the unit of swiping the card or mechanism only need increase card reading interface and image display; Because credit card issuer or mechanism and the unit of swiping the card realize computerize and networking basically, therefore, the investment of image display part can be saved.
