Abstract:
The present invention relates to a system which enhances the availability, credibility, and integrity of a flight data system in case of being hacked to modify or fix the flight data or being attached by internal or external virus and a method thereof. Accordingly, the present invention can automatically protect the flight data on a real-time basis in response to various cyber-attacks paralyzing a monitoring service while the flight data system is operated. The real-time flight data protection system provides an embedded system and ensures a stable system operation by using an enhanced write filter (EWF) and protecting the operating system (OS).
Abstract:
기존의 지능형 로봇 서비스 환경에서는, 콘텐츠를 생성하고 분배하는 콘텐츠 서버의 안전성을 보장할 수 없을 뿐 아니라, 전송 도중 비인가된 접근에 의해서 콘텐츠가 불법 수정될 수 있는 문제점이 있다. 이에 본 발명에서는, 키 관리 서버에서 콘텐츠 서버 및 로봇으로 키를 분배하고, 콘텐츠 서버에서 생성되는 콘텐츠에 대해 키를 이용한 서명값을 생성하여 로봇으로 분배하며, 로봇에서는 키 관리 서버의 키에 대한 서명값과 해당 콘텐츠에 포함된 서명값을 비교하여 서로 일치하는 경우에 해당 콘텐츠를 실행시킬 수 있도록 하였다. 본 발명에 의하면, 지능형 로봇 서비스 시스템에서의 콘텐츠 생성 과정 및 분배 과정의 안전성과 신뢰성을 확보할 수 있는 효과가 있다. 로봇 보안, 콘텐츠 보안, 지능형 로봇
Abstract:
PURPOSE: A device and method for selecting a preferred monitored object and an object monitoring device are provided to deliver the collision possibility between ships to a controller by automatically predicting a credible accident scenario. CONSTITUTION: A route estimation unit(310) estimates a traveling route of a designated first vehicle. A scenario prediction unit predicts a credible accident scenario on the traveling route of the first vehicle based on the traveling route of a second vehicle. A risk calculation unit calculates a first risk related to the accident possibility of each vehicle. A preferred monitored object selection unit(360) selects a preferred monitored object among the whole vehicles In which the first risk is calculated.

Abstract:
PURPOSE: An event information generating device in an intelligent monitoring system and a method thereof, and an event information search device and a method thereof are provided to search event information using event related information in an event monitoring image. CONSTITUTION: An intelligent image recognizing block(202) detects event generation from an obtained monitoring image. The intelligent image recognizing block extracts event information. An encoding block(204) encodes the monitoring image. An event information generating block(206) generates event related information from the extracted event information. A frame parser(210) parses the encoded monitoring image. The frame parser inserts the generated event information to a bit stream. The frame parser generates an event monitoring image.
Abstract:
PURPOSE: A flight plan state management apparatus for plan control and method thereof are provided to accurately manage a departure state and an arrival state of flight by using a departure/arrival-only state processor. CONSTITUTION: A flight plan management device(200) generates a flight plan list based on the inputted flight plan. The flight plan management device sets up the flight plan state of the flight plan included in the flight plan list. A departure/arrival management device(400) generates a departure/arrival flight list based on the set flight plan.
Abstract:
PURPOSE: A random number based block shuffling device for encoding a video is provided to prevent an illegal video data user from acquiring useful information. CONSTITUTION: A random number and key management unit(110) stores a shared key between a video encoding unit and a decoding unit. The random number and the key manager create the random number through the key. A block replacement processing unit(120) creates the classification information as a replacement group. The replacement rule is created using the generated random number. The block replacement processing unit changes the location of the constitution element by the generated replacement rule.
Abstract:
PURPOSE: An apparatus for diagnosing efficient remote security threat and a method thereof are provided to diagnose a device through the reference to a common vulnerability list and report the diagnosis result through a vulnerability diagnosis tool placed at a remote place. CONSTITUTION: A vulnerability analysis unit(10) searches for the determined reference key type to obtain a vulnerability inspection list from a vulnerability list management database, wherein the vulnerability inspection list exists in main characteristic information. An attack agent(40) inspects the vulnerability of the main characteristic information based on the preset characteristic information for the vulnerability inspection list existing in the main characteristic information. A result analysis unit(60) reports the result of the inspected vulnerability of the main characteristic information. A GUI(Graphical User Interface) management unit(70) interfaces the reported vulnerability result through a vulnerability diagnosis tool.
