The present invention relates to a motor driving control system and a control method thereof. The purpose of the present invention is to provide a motor driving control system and a control method thereof, which may change electric current limiting logic, which is applied to a BLDC motor for a cooling fan, in response to an operating speed of the motor to stably protect the motor from an overload in a low-speed driving state as well as an overload in a high-speed driving state.

Motor driving control system and control method thereof

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.

Image-forming apparatus having internal security paper detection unit and image-forming method thereof

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.

Image-forming apparatus having external security paper detection unit and image-forming method thereof

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.

Information insertion method, information extraction method, and information extraction apparatus using dot-based information robust to geometric distortion

The present invention relates to a spammer group extraction apparatus and method, which extract spammer groups that interfere with fair trade and unbiased decision making by sending messages aimed at intentionally slandering other companies (other persons, other products, etc.) on social network services. The spammer group extraction apparatus includes a data collection unit for collecting pieces of data corresponding to social network services. A natural language processing unit preprocesses the pieces of data using a natural language processing algorithm based on big data. An abnormal behavior detection unit detects abnormal behavior based on user identifications (IDs) respectively corresponding to pieces of data, preprocessing of which has been completed. A spammer extraction unit extracts a spammer group using a user ID causing the abnormal behavior and an ID of a user group including the user ID.

Spammer group extraction apparatus and method

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.

Method and apparatus for preventing illegitimate outflow of electronic document

Security printing paper based on a chipless radio frequency (RF) tag and a method of manufacturing the same are provided. The security printing paper based on a chipless RF tag includes first base paper, second base paper, and one or more chipless RF tags. The chipless RF tags are disposed between the first base paper and the second base paper. At least one layer configured to prevent the locations of the chipless RF tags from being exposed to the outside and to enable the security printing paper to be detected is formed on one or more of the first base paper and the second base paper.

Security printing paper based on chipless radio frequency tag and method of manufacturing the same

A method for preventing leakage of a printout using security paper includes registering, by an export registration device, information about a printout of an electronic document by generating the information about the printout and transmitting the information about the printout to an export management server, outputting, by a security printer, a security printout by printing content and a security identifier of the electronic document on paper including a security substance, and determining whether or not to export the security printout, by a leakage detection device, by inspecting whether or not the security printout includes the security substance and detecting the security identifier. The security identifier includes security information about the printout of the electronic document, and the information about the printout of the electronic document includes information about a unique value allowing the printout to be uniquely identified.

Method and apparatus for preventing leakage of printout using security paper

An apparatus and method for preventing the illegitimate exit of a printed document by applying a security material. The apparatus includes an exit registration unit, a security printer unit, an exit management server unit, and an illegitimate exit detection unit. The exit registration unit generates information about the printed document of an electronic document, and sends the information to register the information about the printed document. The security printer unit prints the content and security identifier of the electronic document, and generates a secure printed document by applying a security material. The exit management server unit records and determines whether the secure printed document has been exited. The illegitimate exit detection unit detects the security material of the secure printed document, generates an exit warning, analyzes the security identifier, and determines whether the secure printed document is to be exited.
