摘要:
An apparatus and method of protecting an RFID password, and an RFID tag access method are provided. The apparatus for protecting an RFID password comprises a recording medium on which the password for the RFID tag is printed, and a disposable shielding member that can be removed physically or chemically, formed on the surface of the recording medium to visually shield the password. Accordingly, the RFID password can be provided securely to a user, and the user can access the RFID tag using the RFID password.

A method and an apparatus for providing a service using an RFID tag identifier in an RFID system are provided. The method includes: identifying the RFID tag for providing the service; acquiring an object identifier and a unique item identifier from the RFID tag and determining whether or not each of the identifiers can be interpreted; and disregarding the RFID tag if either of the identifiers cannot be interpreted, and determining whether or not the service should be provided according to validity of the tag identifier of the RFID tag if both of the identifiers can be interpreted. In addition, directly after interpreting the unique item identifier stored in the RFID tag, instead of providing information searches or service, an operation of determining whether or not the tag identifier of the RFID tag is used or issued by an RFID system is performed using the tag identifier stored in the RFID tag. Accordingly, it is possible to prevent the RFID tag issued intentionally or by mistake and having the same object identifier and unique item identifier stored in the RFID tag from receiving erroneous operations or unsuitable service.

A technology for providing a service based on an electronic tag. A personalized service provider issues a new code that replaces a code recorded on an electronic tag which is attached to a product purchased by a purchaser, sets a privacy policy of the purchaser, authenticates the new code and purchaser information, and provides a service associated with the product in a limited manner according to the set privacy policy when a person who accesses the personalized service provider is not the purchaser of the product.

Provided are an apparatus for resolving a code, an apparatus for providing code information, and methods used by the apparatuses, which can resolve various codes recorded in a storage medium, such as a radio frequency identification (RFID) tag, or which can obtain content corresponding to the codes. The apparatus for resolving a code comprises a reader which reads an object identifier and a code; a transceiver which transmits information about the object identifier and receives code information required for resolving the code, which is provided in response to the transmitted information; and a resolver which resolves the read code based on the received code information.

A sensor node address management data structure and a method of managing a sensor network using an identifier of a sensor node can provide a single management system based on ID information used to identify the sensor node even though a sensor network management system does not provide a plurality of management systems based on an individual identification system for sensor networks and sensor nodes that are to be built in a variety of network environments. The sensor node address management data structure that is managed by a network management system for managing a sensor network includes: a first field including an identifier allocated to a sensor node; a second field indicating a network management type of the sensor node to make a connection to the sensor network; and a third field providing address information on the sensor node necessary for the connection to the sensor network.

A three-dimensional (3D) image sensor and a stereoscopic camera having the same are provided. The 3D image sensor includes one or more image acquisition regions, each image acquisition region having a plurality of pixels; and an output signal generation controller configured to extract pixel signals from two regions of interest (ROIs) set within the image acquisition regions and output image signals based on the pixel signals, the ROIs being apart from each other. The output signal generation controller may minutely adjust the position of at least one of the ROIs in accordance with a convergence adjustment signal. The output signal generation controller may vertically or horizontally move each of the ROIs in accordance with a camera shake signal and may thus correct camera shake. The output signal generation controller may align the ROIs with left and right lenses in an optical system. The output signal generation controller may vertically or horizontally move each of the ROIs in accordance with an optical axis correction signal and may thus correct an optical axis error resulting from an optical is axis misalignment.
