Abstract: An apparatus and method for generating a two-dimensional (2D) barcode and an apparatus for extracting 2D barcode information. The apparatus for generating a 2D barcode includes a metadata creation unit for creating metadata corresponding to insertion data and a 2D barcode, a data conversion unit for generating data blocks by converting the insertion data based on the metadata, a pattern generation unit for generating metadata patterns and data block patterns by substituting respective predefined symbols for the metadata and the data blocks, and a 2D barcode generation unit for generating a 2D barcode that contains distortion correction patterns, the metadata patterns, and the data block patterns.

Abstract: Security paper based on an RF tag using a dipole array structure and a method for manufacturing the security paper. The security paper based on an RF tag using a dipole array structure includes first base paper, second base paper, and an RF tag printed on at least one of the first base paper and the second base paper, wherein the RF tag is configured such that multiple dipole antennas form an array structure. Also, the security paper based on an RF tag using a dipole array structure may include a layer configured with a pattern or a color or a carbon-coated layer, whereby the location of the RE tag is prevented from being exposed and whether the corresponding paper is security paper may be detected.
