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.

Abstract: Disclosed herein are an apparatus and method for verifying a detection rule. The apparatus for verifying a detection rule includes a grammar checking unit for checking for a grammatical error in a loaded detection rule, a false-positive rate calculation unit for calculating a false-positive rate of the loaded detection rule by applying a latent Dirichlet allocation algorithm to a signature used in the detection rule, and a similarity checking unit for checking similarity between the detection rule and an existing pre-stored detection rule.
