Description

本発明は、偽造防止効果が必要とされる、クレジットカード、キャッシュカード等、様々なカード媒体などの偽造防止担体に適用でき、さらには複写機やスキャナーによる偽造を効果的に防止できるとともに、安価に製造することができるようにした偽造防止カード、認証用タグなどの偽造防止担体及びそれらの読み取りにより行うその認証方法に関するものである。   INDUSTRIAL APPLICABILITY The present invention can be applied to anti-counterfeit carriers such as credit cards, cash cards, and other card media that require an anti-counterfeit effect, and can effectively prevent forgery by a copying machine or a scanner and is inexpensive. The present invention relates to an anti-counterfeit carrier such as an anti-counterfeit card, an authentication tag, and the like, and an authentication method performed by reading them.

一般に、認証情報を磁気的に書き込む磁気カードやデータメモリ機能を有するＩＣカードは、偽造あるいは認証情報が盗用されるおそれがあり、偽造または盗用を防止する技術が社会的に必要とされている。   In general, a magnetic card for magnetically writing authentication information or an IC card having a data memory function has a risk of forgery or authentication information being stolen, and a technology for preventing forgery or theft is socially required.

従来、偽造あるいは盗用の回避を目的とした認証用タグとして、データキャリアが知られている。このデータキャリアは、使用者固有の認識情報として認識情報部が付与され、その認識情報部を基体となる単色の熱可塑性樹脂のペレット及びアットランダムに配列される金属粉を押出機により同時形成したものである（例えば特許文献１参照）。   Conventionally, a data carrier is known as an authentication tag for the purpose of avoiding forgery or theft. This data carrier is provided with a recognition information portion as user-specific recognition information, and the recognition information portion is formed simultaneously with a single-color thermoplastic resin pellet and at-randomly arranged metal powder by an extruder. (See, for example, Patent Document 1).

しかしながら、このような従来のデータキャリアはアットランダムな金属粉を用いることから偽造及び複製は困難であるものの、ランダム模様を形成する金属粉が直接読み取られる為、例えばコピー機による識別情報のコピーに対し、確実に回避できない恐れがある。   However, since such a conventional data carrier uses at-random metal powder, forgery and duplication are difficult, but since the metal powder forming a random pattern is directly read, for example, for copying identification information by a copying machine. On the other hand, there is a risk that it cannot be avoided reliably.

特許文献は以下の通り。
特開平１０−４４６５０号公報 The patent literature is as follows.
Japanese Patent Laid-Open No. 10-44650

上述の問題点を解決すべく、本発明は、このような従来の要請に応えたものであり、特に偽造および盗用による複製を確実に回避して、信頼性および安全性を高めると共に、より低コストに製造できる偽造防止カードおよび認証用タグなどの偽造防止担体の提供を目的とする。   In order to solve the above-mentioned problems, the present invention has responded to such a conventional request, and in particular, avoids duplication by forgery and theft, thereby improving reliability and security, and lowering the reliability. An object is to provide an anti-counterfeit carrier such as an anti-counterfeit card and an authentication tag that can be manufactured at low cost.

上記課題を達成する為になされた請求項１に記載の発明は、片面あるいは両面に平面画像が設けられている透明な基材シートが、該平面画像が合計で３つ以上になるように積層されてなる透明領域を有する偽造防止担体を、撮影角度の異なる少なくとも２台のイメージセンサにて読み取り、各イメージセンサの読取画像を合成して暗号化及びコード化を行い、データベースにあらかじめ記録されているコードと一致するか否かで真偽判定を行うことを特徴とする偽造防止担体の認証方法である。
In order to achieve the above object, the invention according to claim 1, wherein the transparent base sheet provided with a flat image on one or both sides is laminated so that the total number of the flat images is three or more. The anti-counterfeit carrier having a transparent area is read by at least two image sensors with different shooting angles, and the read images of each image sensor are synthesized and encoded, and recorded in the database in advance. An authentication method for a forgery-preventing carrier characterized in that authenticity determination is performed based on whether or not the code matches a certain code .

また、請求項２に記載の発明は、前記平面画像の少なくとも１つが赤外線吸収材料と赤外線透過材料もしくは赤外線透過材料のみで形成され、前記撮影角度の異なるイメージセンサのうち、少なくとも１台のイメージセンサは赤外領域のみを読み取ることを特徴とする請求項１に記載の偽造防止担体の認証方法である。
According to a second aspect of the present invention , at least one of the planar images is formed of only an infrared absorbing material and an infrared transmitting material or an infrared transmitting material, and at least one of the image sensors having different shooting angles. The method for authentication of a forgery-preventing carrier according to claim 1, wherein only the infrared region is read .

また、請求項３に記載の発明は、前記平面画像が、線画もしくは点画もしくは線画と点画の組み合わせで形成されていることを特徴とする請求項１または２記載の偽造防止担体の認証方法である。
The invention according to claim 3 is the authentication method for a forgery-preventing carrier according to claim 1 or 2, wherein the planar image is formed by a line drawing, a point drawing, or a combination of a line drawing and a point drawing. .

また、請求項４に記載の発明は、担体がカード状をしていることを特徴とする請求項１から３のいずれかに記載の偽造防止担体の認証方法である。
The invention according to claim 4 is the authentication method for a forgery-preventing carrier according to any one of claims 1 to 3 , wherein the carrier has a card shape.

また、請求項５に記載の発明は、担体がタグ状をしていることを特徴とする請求項１から３のいずれかに記載の偽造防止担体の認証方法である。
The invention according to claim 5 is the authentication method for the forgery-preventing carrier according to any one of claims 1 to 3 , wherein the carrier is in a tag shape.

本発明の偽造防止カード及び認証用タグなどの偽造防止担体は、透明媒体の三層以上の線画もしくは点画などの平面画像をお互いの一部もしくは全部が視認できる様に形成されたもので、撮影角度が異なる少なくとも２台のイメージセンサにて前記透明部分の三層以上に設けられた線画もしくは点画などの平面画像を重なるかたちで読取画像として読み取り、前記イメージセンサの読取画像より真偽判定を行う。   The anti-counterfeiting carrier such as the anti-counterfeit card and the authentication tag of the present invention is formed so that a part or all of a plane image such as a line drawing or stipple of three or more layers of a transparent medium can be visually recognized. At least two image sensors with different angles read a plane image such as a line drawing or a stipple provided on three or more layers of the transparent portion as a reading image, and authenticity is determined from the reading image of the image sensor. .

この構成の偽造防止カード及び認証用タグなどの偽造防止担体は、従来の偽造カードの製造方法のように、磁気カードもしくはＩＣカードの磁気データもしくはＩＣのメモリデータを盗用し、このデータをあらかじめ大量に製造した磁気カードもしくはＩＣカードにデータを書き込み偽造カードを製造する方法が不可能になることにより、偽造防止効果、特にデータ盗用に対して効果的である。   The anti-counterfeiting carrier such as the anti-counterfeit card and the authentication tag of this configuration is to steal the magnetic data of the magnetic card or the IC card or the memory data of the IC as in the conventional manufacturing method of the forgery card, Since the method for manufacturing a counterfeit card by writing data on the magnetic card or IC card manufactured in the above becomes impossible, it is effective for preventing counterfeiting, particularly for data theft.

さらに、ランダム画像などの平面画像の一部を赤外線透過材料で形成し、読み取り時に２台のイメージセンサのうち１台を赤外線画像を読み取れるようにすることで、より一層偽造防止効果が高まる。   Further, by forming a part of a planar image such as a random image with an infrared transmitting material so that one of the two image sensors can read the infrared image at the time of reading, the forgery prevention effect is further enhanced.

図３は、図１の偽造防止カード１の読み取り方法を示す概略図で、偽造防止カード１の裏面から透明窓部１１に向けて光源２０を照射し、互いに撮影角度の異なるイメージセンサＡ１９及びイメージセンサＢ２０にそれぞれ透明窓部１１から投影された画像を取り込む。真偽判定はデータ処理部３０にて行い、イメージセンサＡ１９で撮影した画像２２及びイメージセンサＢ２０で撮影した画像２３を合成２４して暗号化及びコード化２５を行い、データベース２６にあらかじめ記録されているコードと一致するかどうかの真偽判定２７を図４の様に行い、一致した場合次の処理２８を行い、一致しない場合排除２９を行う。   FIG. 3 is a schematic diagram illustrating a reading method of the forgery prevention card 1 of FIG. 1, and the image sensor A 19 and images having different shooting angles are irradiated from the back surface of the forgery prevention card 1 toward the transparent window 11. Images projected from the transparent window portion 11 are taken into the sensor B20. The authenticity determination is performed by the data processing unit 30, and the image 22 photographed by the image sensor A19 and the image 23 photographed by the image sensor B20 are synthesized 24, encrypted and coded 25, and recorded in the database 26 in advance.
