Abstract:
Disclosed are a terminal device capable of blocking execution of an illegally copied mobile application in association with a server, and a method for controlling execution of a mobile application in the terminal device. The disclosed terminal device includes: a control unit which controls execution of a mobile application into which one of a first copyright information corresponding to a normally purchased mobile application and a second copyright information corresponding to an illegally copied mobile application is inserted; and a communication unit which is controlled by the control unit and communicates with the server. The control unit controls the communication unit to transmit the inserted copyright information to the server and receive an execution control message of the mobile application from the server in response to the transmission of the inserted copyright information, and controls execution of the mobile application, based on the received execution control message, when the terminal device is located at a predetermined distance or farther from a reference location at the time a request for executing the mobile application is generated.
Abstract:
PURPOSE: A 3D mouse for a software development document task and a terminal thereof are provided to rapidly perform basic operations of document processing when a complex software development document, which is expressed as a graph type, is written. CONSTITUTION: A moving body(110) receives a physical signal using finger force after a user holds a 3D mouse. A distance sensing module generates a sensing signal by sensing the movement distance and a rotational angle of the moving body based on the physical signal. The distance sensing module includes a first distance sensing module(120), a second distance sensing module(130), and a third distance sensing module(140). [Reference numerals] (210) I/O interface; (220) Control unit; (220a) Moving body recognition module; (220b) Distance/position measurement module; (220c) Reduction/enlargement recognition module; (230) Storage unit; (240) Input and output unit
Abstract:
PURPOSE: A malicious packet blocking method and a system thereof are provided to detect worm virus infection after comparing an inputted packet with an outputted packet. CONSTITUTION: A computer(100) receives a receiving packet from network and transmits a transmitting packet. A security chip(200) monitors the receiving packet. The security chip stores the receiving packet in a buffer and compares the transmitting packet with the receiving packet.

실행 프로그램 분석을 위한 코드 변환 방법 및 그 장치가 개시된다. 본 발명의 실행 프로그램 분석을 위한 코드 변환 방법은 실행 프로그램을 둘 이상의 코드로 분할하는 단계, 상기 분할된 코드의 일 부분을 미리 정해진 대체 코드로 대체 혹은 삭제하여 변형 코드를 얻는 단계, 상기 변형 코드를 실행하여 실행결과를 얻는 단계, 및 상기 실행 결과에 기초하여 상기 실행 프로그램에 포함된 타겟 코드의 위치를 결정하는 단계를 포함하여, 실행코드와 매뉴얼만 주어진 상황 하에서도, 분석하고자 하는 타겟 코드의 위치를 빠르게 찾을 수 있다. 실행 코드, 프로그램 분석, 디버깅
Abstract:
PURPOSE: A file capture prevention method and system using a malicious code, and a recording medium are provided to prevent the deletion or damage of general file/data information with a security system on a network or the security system of a transmitting side. CONSTITUTION: In case a file is relevant to a limit file, a first signature insertion unit inserts a first code corresponding to a malicious code detection signature into the file(S41,S42). In case files are transmitted to the outside of a system, a second signature insertion unit inserts a second code corresponding to the malicious code detection signature into the files(S43). A filter filters the files in which the first code and the second code are altogether inserted(S44). A sensing unit senses hackers(S45).
