。For example, in the case of credit cards, identification cards, etc., which use signatures, facial photographs, etc. to confirm the identity of the card holder, changes to the signature, replacement of facial photographs, etc. may be required. If a forgery is made, it may be used for unauthorized purposes. Therefore, there is a strong demand for a means to prevent or detect such forgery.

のである。The present invention has been made to satisfy such a need, and its purpose is to provide a method that can detect when a signature on a certificate card or an image such as a facial photograph is forged. The purpose of the present invention is to record an image signal obtained by scanning the above-mentioned image on a magnetic recording band on the card when issuing a card, and to scan the image and reproduce the magnetic recording band when using this identification card. The presence or absence of forgery of the image is detected by comparing the image signal obtained by this scanning with the image signal obtained by reproducing the magnetic recording band.
以下に本発明を図面の実施例に基づき詳細に説明する。The present invention will be explained in detail below based on embodiments of the drawings.
第１図は本発明にかかる証明カードの平面図であり、第
２図及び第３図は本発明方法の工程を示す説明図である
。FIG. 1 is a plan view of a certificate card according to the present invention, and FIGS. 2 and 3 are explanatory diagrams showing the steps of the method of the present invention.
証明カード１は第１図に示されるように力ｉドの所有者
を特定するための顔写真３及び署名５が形成されており
、さらに磁気記録帯２、カードの番号４等が形成されて
いる。As shown in FIG. 1, the identification card 1 has a facial photograph 3 and a signature 5 formed thereon to identify the owner of the ID card, as well as a magnetic recording band 2, a card number 4, etc. There is.
このような証明カード１を発行する際にカードの所有者

像信号として磁気記録帯２に記録する。To describe this more specifically, as shown in FIG. For example, a scanning line 15 that crosses the signature 5 and the facial photograph 5 as shown in FIG.
By adjusting the irradiation position of the light from the light source 11 so that the light can be scanned along the direction shown in FIG. Based on the intensity of the reflected light due to the difference in density between the signature 5 and the face photo 3 as shown, an image signal is output.Since there is no intermediate tone for the signature 5, it is output in white or black. Since the face photograph 6 is a signal having gradations, it is passed through a comparator (not shown) set to a comparator level 16 to generate a binary signal of white or black (FIG. 3 (c)). The number of black lines extracted from this signal is recorded on the magnetic recording band 2 as an image signal.

画像信号をとり出す。When the certification card 1 thus constructed is used, the following processing is performed before the identity of the person is verified using the signature 5 and the facial photograph 6. In other words, if the signature 5 and face photo □6 on such a certificate card are altered, it will be impossible to identify the cardholder, and unauthorized use by another person will be possible. In order to prevent this, the signature 5 and facial photograph 3 are scanned in the same way as when the card was issued, and the same signal processing is performed to obtain an image signal. At the same time, by reproducing the magnetic recording band 2 of this certificate card 1, the image signal recorded at the time of card issuance is taken out.
このスキャニングにより得られた画像信号と磁気記録帯
２を再生することで得られる画像信号とを比較し、２つ
の信号が一致していれば署名５及セ。The image signal obtained by this scanning is compared with the image signal obtained by reproducing the magnetic recording band 2, and if the two signals match, the signature is 5 and 5.

きる。On the other hand, if the above-mentioned two signals are present, the card is considered to be a fraudulent card with the signature 5 and face photo 3 altered in some way. It can be detected as such.
このようにして、署名５及び顔写真３が偽造されていな
いと判定された証明カードが前述した署名５及び顔写真
３に基づく本人の確認に供されることになる。In this way, the certificate card whose signature 5 and face photo 3 are determined not to have been forged is used for identification based on the signature 5 and face photo 3 described above.
なお、上記説明に於いては証明カードに形成する本人を
特定するための画像を署名及び顔写真としたがこれに限
られることなく指紋及びこれらの組み合わせでも良い。In the above description, the image for identifying the person formed on the certificate card is a signature and a facial photograph, but the present invention is not limited to this, and a fingerprint or a combination thereof may be used.

きる。In addition, the image signal recorded on the magnetic recording band 2 and used as data to confirm whether it is a counterfeit item is based on the number of black lines, but it may also be based on the width of the black lines, the spacing, etc., or the density may be changed. The object may be divided into several levels. Yet again. In Example F, the image signal was obtained by one scan along the scanning line, but the scanning line and the number of scans can be selected arbitrarily.

のである。As described above, according to the present invention, if the image of the identification card used to identify the owner is tampered with using an image unique to the owner such as a face photo or signature, this can be easily and reliably detected. This can prevent forgery of this type of certification card and unauthorized use of the certification card.
