Abstract: The present invention relates to a vessel traffic service system and a method for extracting accident data, and more particularly, to a technique that search and extracts possible event traffic data automatically from data of a concerned area without knowing exact time when a marine accident occurs. The vessel traffic service system includes: an input unit receiving conditional information for extracting accident occurrence data from a user; a storage unit storing at least one of an automatic identification system (AIS) signal, a radar signal, and a camera image signal; and a control unit extracting an event occurrence part from at least one of the AIS signal, the radar signal, and the camera image signal of a point and a time at which an accident occurs in accordance with the conditional information to generate an accident candidate list.

Abstract: The present invention relates to an apparatus and method that control a vessel deviating from an anchorage using wide-range sensor-based spherical trigonometry. In the method, vessels anchored in an anchorage are monitored. The anchorage is defined as a group, and the group of the anchored vessels is managed. Leaving of a vessel, needing to deviate from the anchorage, from the group is controlled. If a vessel recognized as a vessel identical to one that left the group requests anchoring after a predetermined period of time has elapsed, the anchoring-requesting vessel is controlled.

Abstract: A method and apparatus for predicting the risk of the collision of an object are disclosed herein. The apparatus for predicting the risk of the collision of an object includes an information reception unit, an input processing unit, a risk calculation unit, and a provision unit. The information reception unit receives information transmitted by each of a plurality of heterogeneous transmission apparatuses. The input processing unit processes the information into input information required to calculate a degree of risk of a collision between objects. The risk calculation unit calculates the degree of risk of the collision between the objects using the processed input information. The provision unit externally outputs the degree of risk of the collision, and performs control so that the risk of the collision between the objects can be externally predicted.

Abstract: An apparatus and method for providing traffic control service are disclosed herein. The apparatus for providing traffic control service includes a multi-sensor fusion processing unit, an image object tracking and combination unit, and an information provision unit. The multi-sensor fusion processing unit generates the location information of a vessel by fusing radar information and automatic identification system (AIS) information together. The image object tracking and combination unit sets a detection area on a closed-circuit television (CCTV) image based on the information of the vessel, and detects the vessel by performing image processing within the set detection area. The information provision unit generates mapping display information based on the information of the vessel and the result of the detection achieved by performing the image processing, and displays the generated mapping display information within a CCTV screen, thereby providing traffic control service.

Abstract: The present invention relates to an agent apparatus and method for sharing anonymous identifier-based security information among security management domains. A plurality of security information sharing agent apparatuses respectively located in a plurality of security management domains and configured to collect security information and transmit collected security information to outside of the security management domains.

Abstract: An authentication apparatus for a non-real-time IPTV system decrypts a first encrypted value included in a contents request message received from a device using a preset session key, and then verifies the validity of the contents request message. If the verification results of the contents request message are valid, the authentication apparatus encrypts a variation between timestamps of the authentication apparatus and the device using the session key, and then generates a second encrypted value. After verification information by which the device is capable of verifying the authentication apparatus has been generated using the second encrypted value, the authentication apparatus sends verification information, together with contents corresponding to the contents request message, to the device.
