20100026826 | APPARATUS FOR PROTECTING IMAGE - An image protection apparatus includes an information collecting unit for collecting personally identifiable information to be embedded in images captured by an image capturing instrument; and an information processing unit for extracting personal information from the collected personally identifiable information. Further, the image protection apparatus includes an information embedding unit for embedding the extracted personal information into a captured image; and an image signaturing unit for writing a signature on the captured image by using the extracted personal information. | 02-04-2010 |
20100033363 | SHIP TRAFFIC CONTROL APPARATUS AND METHOD THEREOF - A ship traffic control apparatus includes a location recognizer for measuring a location coordinate of a ship by using a satellite location-based service; a ship identifier/location coordinate manager for storing the location coordinate as coordinate information corresponding to a ship identifier; an accident processing unit for providing an accident information when an accident occurs; and an operation controller for forming location information by mapping between the coordinate information and navigation information, transmitting the location information to other ships or a control system in a prescribed cycle through a radio communication unit, and transmitting accident occurrence information including the accident information and the location information to other ships or the control system. | 02-11-2010 |
20100140361 | RFID TAG - Provided is an RFID tag. When no external pressure is applied to a packaging structure, a wire for transmitting power and data from an antenna is separated from an RFID chip by an air layer. When external pressure is applied to the packaging structure, the wire is connected to the RFID chip to transmit the power and data between the antenna and the RFID chip. | 06-10-2010 |
20100146273 | METHOD FOR PASSIVE RFID SECURITY ACCORDING TO SECURITY MODE - Provided are a method for passive radio frequency identification (RFID) security according to a security mode. An RFID tag transmits its own current security mode to a reader and the reader drives a security protocol depending on the current security mode of the RFID tag. Also, the reader grasps the ability of the tag and then the reader drive a protocol suitable for the ability through the security mode. | 06-10-2010 |
20100208083 | SYSTEM AND METHOD FOR PROVIDING APPLICATION SERVICE USING IMAGE DATA - There is provided a system and method for providing an application service using image data. One image data processing server collects images (for example, still images and moving images) captured by various kinds of image capturing apparatuses, such as CCTV systems and processes the collected images into data required to provide application services. A plurality of application service servers only provide processed data of the image data processing server without requiring an additional process to a display device of a user. Accordingly, the configuration of each of the application service servers is simplified to thereby reduce manufacturing costs. | 08-19-2010 |
