Description

Authenticity Proof Method}

종래의 신분증, 신용 카드, 은행 카드 등 진품 증명이 매우 중요한, 본인의 것임을 증명하는 카드들은 (이하 "증명 카드"라고 칭한다) 균일한 플라스틱 소재로 제조되어 있고, 그 카드상에 조성된 바코드나 마그네틱 띠 또는 내장된 반도체에 관련 정보를 기록하고 덧붙혀 소유자의 사진이나 홀로그래피를 붙혀서 위조품을 방지하려 하였다.Cards that prove authenticity, such as conventional identification cards, credit cards, bank cards, etc. are very important (hereinafter referred to as "certificate cards") made of a uniform plastic material, and barcodes or magnetics formed on the cards. Relevant information was recorded on a strip or embedded semiconductor and attached to the owner's photo or holography to prevent counterfeiting.

본 발명에서는 증명 카드에 무작위적인 미세 구조를 만들어 놓은 후 이 미세 구조를 증명 카드에 " 인위적으로 기록되는 정보" (이하 " 인위적 정보" 라고 칭한다)와 연계하여 컴퓨터에 등록하여 놓고, 추후 인위적 정보가 동일한 증명 카드의 진위를 판별할 때, 이미 동일한 인위적 정보와 연계되어 등록되어 있는 미세 구조를, 진위를 판별하려 하는 증명 카드에 만들어져 있는 무작위적인 미세구조와 비교하여 진위를 판별한다. 인위적으로 기록하는 정보만 수록된 증명 카드는 정교한 기술과 장비가 있으면 위조가 가능하나 자연적으로 생성되는 무작위적인 미세 구조는 그대로 동일하게 재현시켜 복사하기가 불가능하므로 이를 이용하면 증명 카드의 진위를 판별하기가 매우 용이하다.In the present invention, a random microstructure is created in the proof card, and the microstructure is registered in the computer in association with the "artificially recorded information" (hereinafter referred to as "artificial information") on the proof card, and the artificial information is subsequently added. In determining the authenticity of the same proof card, the authenticity is determined by comparing the microstructure already registered in association with the same artificial information with the random microstructure made in the proof card to determine the authenticity. An authentication card containing only artificially recorded information can be forged with sophisticated technology and equipment.However, it is difficult to determine the authenticity of the authentication card because it cannot be reproduced by copying the random microstructure that is naturally generated as it is. Very easy.

본 발명에서는 증명 카드에 무작위적인 미세 구조를 만들어 놓은 후 이 미세 구조에 관한 정보를 증명 카드에 인위적으로 기록되는 정보와 연계하여 컴퓨터 등에 등록하여 놓고, 추후 인위적 정보가 동일한 증명 카드의 진위를 판별할 때, 이미 동일한 인위적 정보와 연계되어 등록된 미세 구조에 관한 정보를, 진위를 판별하려 하는 증명 카드에 있는 미세 구조에 관한 정보와 비교하여 진위를 판별한다. 이하 본 발명의 실시 예에 대하여 예시 도면들을 참조하여 설명한다.According to the present invention, a random microstructure is formed on a proof card, and information about the microstructure is registered in a computer or the like in association with information recorded on the proof card, and the authenticity of the proof card having the same artificial information can be determined later. At this time, the authenticity is determined by comparing the information on the microstructure already registered in association with the same artificial information with the information on the microstructure in the proof card to determine the authenticity. Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

도 1 은 본 발명의 한 예인, 흑색과 백색의 입자 상태의 재료들을 불균일하게 혼합하여 만든 판재를 이용하여 제조된 증명 카드의 한 부분을 확대한 것으로서 두종류의 흑과 백의 입자들이 매우 불규칙적하고 무작위적으로 분포되어 있는 패턴을 보인다. 이러한 무작위적이고 불규칙적인 패턴을 보이는 미세구조를 그대로 동일하게 재현시켜 판재를 만드는 것은 불가능하다. 따라서 신규신용 카드를 발행할 때 특정 부분의 미세 구조에 관한 정보를 문자, 바코드, 마그네틱 띠, 반도체, 또는 광학 코드 등의 방법을 이용하여 인위적으로 기록하는 정보와 연계하여 컴퓨터 등에 등록하여 놓고, 추후 인위적 정보가 동일한 신용카드의 진위를 판별할 때, 이미 동일한 인위적 정보와 연계되어 등록되어 있는 흑과 백의 미세 구조와 비교하여 카드의 진위를 판별할 수 있다. 인위적으로 기록된 정보만 있는 증명 카드는 정교한 기술과 장비가 있으면 위조 카드를 제조할 수가 있으나 이처럼 자연적으로 나타나는 불규칙적이고 무작위적인 패턴을 갖는 미세 구조를 그대로 동일하게 재현시켜 판재를 제조하는 것은 불가능하므로 이러한 판재로 제조한 증명 카드는 진품임을 용이하게 증명할 수가 있다. 상기 예에서는 두가지의, 흑색과 백색의 재료들로 불균일하게 혼합되어 만들어진 판재를 예시하여 설명하였으나, 서로 다른 색상의 다수의 재료들로 불균일하게 혼합하여 판재를 제조하면 복잡성을 더욱 높일 수 있어 위조품을 제조하기가 더욱 어려워진다.1 is an enlarged view of a part of a proof card manufactured by using a plate made by mixing non-uniformly mixed black and white particles, which is an example of the present invention, in which two kinds of black and white particles are very irregular and random. It shows a pattern distributed by enemy. It is impossible to make a plate by reproducing the same microstructure showing random and irregular patterns. Therefore, when issuing a new credit card, information about the microstructure of a specific part is registered in a computer or the like in association with information recorded artificially using a method such as a character, a barcode, a magnetic stripe, a semiconductor, or an optical code. When the artificial information determines the authenticity of the same credit card, it is possible to determine the authenticity of the card by comparing with the fine structure of black and white registered in association with the same artificial information. Proof cards with only artificially recorded information can produce counterfeit cards with sophisticated technology and equipment, but it is impossible to manufacture plates by reproducing the same microstructure with irregular and random patterns that appear naturally. A proof card made of sheet material can easily prove that it is genuine. In the above example, a plate made by mixing unevenly with two kinds of black and white materials has been described as an example. However, if a plate is manufactured by mixing unevenly with a plurality of materials having different colors, the complexity can be further increased. It becomes more difficult to manufacture.

도 2 는 빛을 반사하는 재료의 표면을 무작위적으로 변형을 시킨 한 예를 보여 주는 것으로서, 표면이 경면인 알미늄 박판을 구기거나, 또는 경면의 알미늄의 표면을 유리를 분쇄하여 만든 작은 입자로 때리면 이처럼 표면이 무작위적인 방향을 갖는 작은 조각 거울들로 이루어진 것과 같은 반짝거리는 표면을 갖는다. 이러한 표면에 빛을 비추면 표면의 작은 조각 거울들에서 빛이 무작위적인 방향으로 반사하게 되며 이 무작위적인 방향으로 반사되는 빛들의 앞에 평면을 놓으면 그 평면상에 반사된 빛의 점들로 이루어진 하나의 패턴이 형성하게 된다. 따라서 상기와 같이 무작위적인 방향을 갖는 작은 조각 거울들로 이루어진 표면을 갖는 재료를 증명 카드의 한 부분에 부착시켜 놓고, 그 표면에 빛을 비추어 반사되는 빛의 점들로 이루어지는 패턴을 증명 카드에 인위적으로 기록되는 정보와 연계하여 컴퓨터 등에 등록하여 놓고, 추후 인위적 정보가 동일한 증명 카드의 진위를 판별할 때, 이미 동일한 인위적 정보와 연계되어 등록되어 있는 반사된 빛의 점들로 이루어진 패턴을 증명 카드에 부착되어 있는 무작위적인 방향을 갖는 작은 조각 거울들로 이루어진 표면을 갖는 재료의 표면을 빛으로 비추어 반사되는 빛의 점들로 이루어진 패턴과 비교하여 증명 카드의 진위를 판별할 수 있다.FIG. 2 shows an example of randomly modifying a surface of a material that reflects light, and when a thin aluminum sheet whose surface is mirrored is crushed, or when the surface of the mirror aluminum is struck with small particles made by grinding glass As such, the surface has a shiny surface, such as made up of small mirrors with random directions. Shining light on these surfaces causes light to reflect in random directions on the small mirrors of the surface, and a pattern consisting of points of light reflected on that plane when placed in front of the light reflected in this random direction. This will form. Therefore, a material having a surface composed of small mirrors having a random direction as described above is attached to a part of the proof card, and a pattern consisting of dots of light reflected by light shining on the surface is artificially attached to the proof card. Registered in the computer or the like in association with the recorded information, and when the artificial information later determines the authenticity of the same authentication card, a pattern consisting of reflected light dots already registered in association with the same artificial information is attached to the authentication card. The authenticity of the proof card can be determined by comparing the surface of the material with the surface of the small mirrors with random directions to light with a pattern of reflected light dots.

광원으로서는 점 광원 또는 평행 광선들로 이루어진 면 광원이 사용되어 상기 표면을 전체적으로 비추어 2 차원적인 반사된 빛의 점들로 이루어진 패턴을 얻을 수 있으며, 또는 빔 형태의 빛으로 표면을 스캐닝하면서 반사된 빛의 위치를 측정하여 이들로부터 작은 거울들의 표면상에서의 위치와 기울기 방향들을 계산하면 더욱 정교한 데이타를 얻을 수 있다.As a light source, a point light source or a plane light source consisting of parallel rays can be used to illuminate the surface as a whole to obtain a pattern of two-dimensional reflected light points, or to scan the surface with beam-shaped light, By measuring the position and calculating the positions and tilt directions on the surface of the small mirrors, more sophisticated data can be obtained.

도 3 은 투명한 재질 내에 빛을 반사하는 작은 판상의 입자들이 무작위적으로 분산되어 있는 한 예를 확대하여 보여 주는 것으로서, 이처럼 빛을 반사하는 작은 판상의 입자들이 무작위적으로 분산되어 있는 투명한 재질로 제조된 증명 카드에 빛을 비추면 작은 판상의 입자들로부터 빛이 무작위적인 방향으로 반사하게 된다. 이 무작위적인 방향으로 반사된 빛은 그 앞에 평면을 놓으면 그 평면상에 반사된 빛의 점들로 이루어진 하나의 패턴이 형성하게 된다 또한 투명한 재질을 통과하는 빛도 역시 빛을 통과시키지 않는 작은 판상의 입자들에 의해 그 아래로 무작위적으로 분포된 그림자들의 패턴을 이루게 되는데, 상기 두 패턴들, 즉 반사된 빛의 점들과 통과된 빛의 그림자 점들의 위치 정보를 인위적 정보와 연계하여 컴퓨터 등에 등록하여 놓고, 추후 인위적 정보가 동일한 증명 카드의 진위를 판별할 때, 이미 동일한 인위적 정보와 연계되어 등록되어 있는 반사된 빛의 패턴과 통과된 빛의 그림자들의 패턴을, 진위를 판별하려 하는 증명 카드로부터 반사되는 빛의 점들로 이루어진 패턴과 통과된 빛의 그림자들로 이루어진 패턴을 함께 비교하여 진위를판별할 수 있다.3 is an enlarged view of an example in which small plate-shaped particles reflecting light are randomly dispersed in a transparent material, and thus, is made of a transparent material in which small plate-like particles reflecting light are randomly dispersed. Shining light on a given proof card causes light to reflect randomly from small plate particles. The light reflected in this random direction is placed in front of it to form a pattern consisting of the points of light reflected on the plane. Also, light that passes through a transparent material does not allow light to pass through. The patterns of randomly distributed shadows are formed below the two patterns, and the positional information of the two patterns, that is, the reflected light points and the shadow points of the transmitted light, is registered in a computer or the like in association with artificial information. In the future, when the artificial information determines the authenticity of the same authentication card, the pattern of reflected light and the shadows of the transmitted light, which are registered in association with the same artificial information, are reflected from the authentication card to determine the authenticity. The authenticity can be judged by comparing the pattern of the dots of light with the pattern of the shadows of the light passing through.

상기의, 빛을 반사하는 작은 판상의 입자들이 무작위적으로 분산되어 있는 투명한 재질로 제조된 증명 카드를 비추는 광원 역시 점 광원 또는 평행 광선들로 이루어진 면 광원이 사용되어 상기 표면을 전체적으로 비추어 반사된 빛의 점들 그리고 통과된 빛의 그림자들의 패턴들을 얻을 수 있으며, 또는 빔 형태의 빛으로 표면을 스캐닝하면서 반사된 빛의 위치를 측정하여 이들로부터 작은 판상의 입자들의 위치와 기울기 방향들을 계산하면 더욱 정교한 데이타를 얻을 수 있다.The light source illuminating the identification card made of a transparent material in which the small plate-shaped particles reflecting light are randomly dispersed is also used as a point light source or a plane light source composed of parallel rays to reflect the entire surface and reflect the light. You can get the points of and the patterns of the shadows of the passing light, or by measuring the position of the reflected light while scanning the surface with beam-shaped light and calculating the positions and tilt directions of the tiny platelets from them Can be obtained.

자연적으로 생성되는 무작위적인 미세 구조는 그대로 동일하게 재현시켜 복사하기가 불가능에 가까우므로 증명 카드에 인위적으로 기록되는 정보와 함께 그 미세 구조를 컴퓨터 등에 등록하여 놓으면 추후 인위적 정보가 동일한 증명 카드의 진위를 판별하기가 매우 용이하다.Naturally generated random microstructures are almost impossible to reproduce by copying them in the same way, so if the microstructures are registered with a computer or the like, the information is artificially recorded. Very easy to discern
