Abstract:
PURPOSE: A latent image-printed matter capable of preventing the forgery, an intaglio for producing thereof, and a producing method of the latent image-printed matter are provided to offer a latent image effect to a printed product using the intaglio including asymmetric image line structures. CONSTITUTION: A latent image-printed matter(500) includes first protrusions(44) and second protrusions(42). The direction of edges on the second protrusions is different from the direction of edges on the first protrusions. The first and second protrusions are produced by an intaglio with asymmetric image line structures to express a latent image.

Abstract:
PURPOSE: A system and a method for confirming an ID card using a database are provided to easily discriminate the truth of the ID card through the online, and reinforce security while changing the present system minimally. CONSTITUTION: A wire/wireless communication terminal(10) encrypts/transmits a received ID card number to an ID card management center(50) connected through a web browser and decrypts/displays the received photo data as an image. A main database(51) stores the ID information of subscribers and the photo information on the ID card as digital data. A search server(57) searches/extracts the registered photo data of the ID card number stored in the main database by receiving the ID card number requested from the communication terminal. A communication server(55) displays a photo on the communication terminal by receiving the extracted photo data from the search server.
Abstract:
In a printed matter including a latent image part having a latent effect, the latent part includes a first latent part (100) and a second latent part (200). The first latent part (100) has a base side with a circular or polygonal shape and includes a separation protrusion part (111) which protrudes in an upper direction and has a center part which is higher than a peripheral part. The separation protrusion part (111) divides a first protrusion part (110) into first separation surfaces (112). The second latent part (200) has a base side which has a circular or polygonal shape and includes a separation recess part (211) which protrudes in an upper direction and has a center part which is deeper than the peripheral part. The separation recess part divides second protrusion parts (210) into second separation surfaces (212).
