Abstract: The present invention relates to a micropattern layer based image film and a method for manufacturing the same. The image film comprises: a sacrificial layer; a first micropattern layer formed on the sacrificial layer; a second micropattern layer formed on the first micropattern layer; a focal length layer formed on the second micropattern layer; and a micro-image pattern formed on the focal length layer, wherein the first micropattern layer includes a plurality of concave parts extending in one direction, and concave curved surfaces of the plurality of concave parts are formed adjacent to the sacrificial layer; the second micropattern layer includes a plurality of convex parts extending in one direction, and convex curved surfaces of the plurality of convex parts are formed adjacent to the focal length layer; and the first micropattern layer and the second micropattern layer are orthogonal to each other.

Abstract: The inventive concept relates to a radio frequency identification (RFID)-based genuine product certification service system and method employing a code update algorithm for forgery prevention in which a genuine product certification processing server stores an RFID tag access code and a variable genuine product certification code in an RFID tag through a wired or wireless terminal including an RFID writer and reader and a database thereof for genuine product certification to determine whether a product or document is genuine using the tag information stored in the RFID tag and the genuine product certification code when RFID tags are used to prevent imitations (fakes) of medicine, food and beverages, luxury goods, alcohol, products, etc.
