The present invention relates to a two-dimensional code structure having fine holes and an information analysis system using the same. The fine holes penetrating the structure are formed in an image shape identical to a two-dimensional code according to a predetermined rule. A shape, a size, density, a processing depth, an incident angle, radius of an inlet and outlet of a hole are considered in forming the two-dimensional code. The two-dimensional code is realized in a visible or invisible form on a target structure composed of a single-layered or multi-layered sheet having various optical, chemical, and physical properties and a continuous roll through a printing, an etching, an engraving, etc. According to the present invention, a code can be recognized from the code-formed structure by means of transmission, reflection or projection of a light, thereby enabling the code to contain a variety of and a large amount of information and enhancing security. |
