Abstract: An image-forming apparatus having an internal security paper detection unit and an image-forming method related to the apparatus. The image-forming apparatus controls a paper feed unit so as to feed a single sheet of paper from a paper stack unit when a command for forming an image on RF tag paper is input, controls a paper transfer unit so as to provide the paper fed from a security paper cassette unit to an image-forming unit along a transfer path, and controls the image-forming unit so as to normally form a desired image on the moving RF tag paper when an RF tag detection signal is input from an RF tag, paper detection unit, whereby the image is formed only on the security paper in which an RF tag is inserted and thus illegal leakage of documents may be prevented.

Abstract: An external security paper detection unit, an image-forming apparatus having the external security paper detection unit, and an image-forming method related to the apparatus. The external security paper detection unit includes a paper stack unit in which sheets of paper are stacked in order to feed the paper, a paper feed unit for feeding the paper stacked in the paper snick unit, a security paper detection unit for detecting whether moving paper is security paper or not, and a unit controller for normally supplying the moving security paper to a manual feed tray if the paper feed unit operates and a security paper detection signal is input from the security paper detection unit, whereby an image is formed only on the security paper, thus preventing the illegal leakage of documents.

Abstract: An information insertion method, an information extraction method, and an information extraction apparatus using dot-based information are provided herein. The information extraction apparatus includes an identification unit and an extraction unit. The identification unit identifies a set of at least one dot output to a target. The extraction unit extracts information from the set of at least one dot.

Abstract: An apparatus and method for preventing illegitimate outflow of an electronic document. The apparatus includes a taking-out control unit, a taking-out management server unit, and a self-response agent unit. The taking-out control unit generates a virtual disk for storing an electronic document to be controlled, and controls the taking-out of the electronic document. The taking-out management server unit authenticates whether the taking-out of the electronic document is legitimate taking-out. The self-response agent unit performs self-extinction when a result indicating illegitimate outflow is received from the taking-out management server unit.
