  • Publication number: 20210141882
    Abstract: Disclosed herein are an apparatus and method for user authentication based on multiple pieces of biometric information. The apparatus may include one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program receives multiple pieces of biometric information from the client device of a user, generates the personal identifier of the user using a neural network and a Bloom filter algorithm, and checks the similarity between the personal identifier of the user and each of personal identifiers previously registered in a database, thereby authenticating the user.

  • Patent number: 10255367
    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.

  • Patent number: 9261880
    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.

  • Publication number: 20150262494
    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.

  • Publication number: 20150241560
    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.
