Abstract: PURPOSE: Prints for preventing duplication and forgery of a video information encoded image according to representation of a latent image and a method for forming the prints are provided to easily judge a forgery. CONSTITUTION: A random number map is generated, and a security code is inputted. An image is inputted to a processor, and the color, size and region of the inputted image are adjusted and normalized. The normalized image is divided into R, G and B components using the random number map. The first coding of making each of the components a square puzzle is carried out. The second coding of imaging the coded information to a single-gradation map is performed. The third coding of combining the imaged information in unit of the basic components to make a square, triangle or circular puzzle or convert the basic components into a single pixel is executed. A coding key code is inserted into the coded image. Video information image is coded and inputted to a processor. Gradient correction, size correction and coding key code of the inputted image are extracted. The security code is inputted or extracted from the coded image. The image is decoded and restored.

Abstract: The paper includes an optical interference pattern(2) equidistantly printed with a plurality of concentric or spiral circles on a base paper(1). When copying the paper, the pattern on the copied paper is deformed because of the optical interference phenomenon to prevent the counterfeit of a bank note or a negotiable instrument. The thickness of the circle line is 70-130 micro meter, and the width between the circle lines is 230-290 micro meter. The optical interference patterns can be overlapped with characters on the paper.

Abstract: 본 발명은 천연색 복사기 특히 CLC 500 천연색 복사기에 의한 복사위조를 방지하기 위한 것인바, 지면(1)에 나선형원(2) 또는 다수개의 밀집동심형원(3)을 형성시켜서 된 것에 있어서, 나선형원92)이나 밀집동심원(3)의 선굵기가 70 내지 130㎛이고 화선간격이 230 내지 290㎛이며 각원의 등간격인 광간섭 패턴을 형성시키므로서, 이를 복사하게 되면 복사물에 원복에서는 보이지 아니하던 선풍기날개모양(4)이나 물결무늬(5)가 발생하도록 한 것임.
