Abstract: The present invention relates to a container security apparatus which is easily attachable/detachable to/from both opening/closing bars of a container to sense whether the container is opened/closed and transmit the sensed information on whether the container is opened/closed to a remote location, to thereby check whether the container is sealed or not on a real time basis and thus safely transport the container, and to thereby check the current position of the container in transit and check whether or not the container has deviated from a predetermined path on a real time basis.

Abstract: The present invention relates to a system for authentication management of a sensor node having a subscription processing function, and a method for operating the system. Upon receiving information about a sensor node allocated with an IP address, the system supports the access of only authorized user equipment to a corresponding sensor node, which blocking any direct access of unauthorized user equipment to the sensor node, thereby strengthening the security of the sensor node. According to the present invention, a relay server receives subscription information from user equipment. The relay server checks permission validity of corresponding user equipment. If the user equipment has a valid permission, the relay server transmits the subscription information to a sensor node, and transmits subscription acceptance information to the user equipment. Then the sensor node transmits the collected and stored information to the user equipment having a valid permission.

Abstract: Disclosed herein is a life saving system with an RFID tag having an IP communication function. The life saving system using RFID tags and a GPS comprises a plurality of RFID tags respectively attached to life jackets of survivors, respectively transmitting distress signals, and transmitting distress signals of other RFID tags when receiving the distress signals from the other RFID tags; smart points arranged in a distress area at predetermined intervals, including position information in the distress signals and transmitting the distress signals with the position information through satellite communication; and a control tower receiving the distress signals including the position information and transmitting a saving command.

Abstract: Provided are a container security device, a container security system, and a security management method which efficiently check opening/closing of a container door and an opening/closing record of the container door and process seal information, cargo state information, base passing information, and location tracking information in real-time from a gate-out process from a shipper (POA) to a gate-in process to a consignee (POD). The container security system includes the container security device which includes a first communication means for providing container seal information through multi-channel communication; and a second communication means for providing information about container transportation and storage in real-time.

Abstract: Provided are a system and a method for controlling a network configuration for a moving object. A monitoring device attached to the moving object, that is, a container loading a cargo, recognizes loading and moving circumstances of the container, construct a network with other containers according to the circumstances and performs connection/disconnection of the container to/from a network and maintenance of the connection until the container departs the origin and arrives at a destination through overland transportation and marine transportation. Accordingly, the state of the container is monitored, monitoring information is transmitted to a container administrator and the power of the monitoring device which constructs an optimized network with other monitoring devices according to container circumstances is saved.
