Abstract:
A communication data protection method based on symmetric key encryption in an RFID(Radio Frequency ID) system, and a reader and a tag for performing the same are provided to use symmetric key encryption, thereby protecting communication data between an RFID tag and an RFID reader. A memory(115) stores a security parameter and a security key. A signal processing unit(113) produces an OTP(One Time Password) value according to an output regression mode by using the security key. The signal processing unit encrypts a message to be transmitted to a reader(101) by the OTP value. A transmitting unit(111) transmits the security parameter and the encrypted message to the reader.

Abstract:
Disclosed are a Radio Frequency Identification (RFID) personal privacy control system and a personal privacy protection method using the same which may dynamically process a privacy level according to peripheral circumstances of an RFID tagged object and an owner of the object, thereby securely protecting personal information associated with the RFID tag. The RFID privacy control server, the RFID privacy control server includes a context-aware information collecting unit to collect at least one context-aware information about a user; a privacy level adjusting unit to adjust a privacy level of the user based on the collected context-aware information; and a privacy control unit to determine, according to the adjusted privacy level, whether access of an RFID reader to RFID tag information is allowed, the RFID tag information corresponding to an RFID tag associated with the user.
Abstract:
A system for authenticating an electronic notarial document and a method for issuing the electronic notarial document are provided to determine whether the notarial document is original by reading an RFID(Radio Frequency Identification) tag and a two-dimensional bar code included in the electronic notarial document. An input interface unit(201) receives electronic notarial document issuing information from at least one or more notarization persons concerned. A document encryption unit(202) generates a document encryption value correspondingly to the inputted electronic notarial document issuing information. A notarization transceiver(203) transmits the generated document encryption value to a terminal of a notary, and then receives the electronic signature value of the notary corresponding to the transmitted document encryption value. A notarial document generating unit(204) produces an electronic notarial document including the electronic notarial document issuing information and electron signature value.

Abstract:
Sensing data relay apparatus and method, sensing data management apparatus and method, a sensor network system thereof are provided to prevent data loss and transmission delay by stably transmitting data in a state that security information and close nodes are not established. A pre-authentication data delay unit(211) relays first sensing data received from a mobile sensor node(200) to a base node(220) at minimum transmission rate, and a security information receiving unit(212) receives and stores not only share encryption key about the mobile sensor node but also re-setup data transmission rate from the base node. An authentication unit(213) authenticates second sensing data received from the mobile sensor node with the share encryption key, and a post-authentication data relay unit(214) relays the authenticated second sensing data to the base node at the re-setup data transmission rate.
Abstract:
A method and a device for data pattern recognition for data protection are provided to convert an original data into a safe form which is not to be analogized after an outflow of a converted original data. A data to be compared is inputted. The inputted data is converted into a template for pattern recognition, and a probe is generated(S1200). A gallery which is a registered template is called to determine whether a probe and a registered template are the same or not(S1210). An area where a probe belongs to is determined, and an area related value of the corresponding area is calculated(S1220). The coordinate of probe and an area related value are compared to each other, and it is determined that the coordinate of probe is in a boundary line which is comprised of thresholds values(S1230). A hash value of the center of the area in which probe belongs and the hash value stored in gallery are compared to determine whether the two hash value are the same. If the hash values are different, it is determined as different kind(S1260). If the hash values are the same, it is determined whether the coordinate of probe is inside the defined decision boundary based on the center point coordinate(S1240). The coordinate of probe and area related value are classified as the same kind(S1250).
Abstract:
A system and a method for authenticating products and verifying a service provider by using an RFID signature tag are provided to enable a user to determine authenticity of the products or documents online by using RFID technology, and to offer the authenticity result to the user, thereby enabling the user to receive a reliable service. A terminal(201) performs verification for a signature of a service provider(206) providing products with an RFID(Radio Frequency Identification) tag(202) or a service related to the products, by accessing the RFID tag. A key management server(203) stores keys of service providing objects of the service provider, and provides the keys according to a request of the terminal. The service provider provides the products or the products related service.
