| 20090183231 | USER TERMINAL WITH SECURITY FUNCTION AND SECURITY-CONTROL METHOD - A user terminal apparatus with a security function and a security-control method are provided, which may prevent unauthorized use of the user terminal apparatus without requiring a user to lock up the user terminal apparatus. The user terminal apparatus includes an input sensing unit which senses a user's input to the user terminal apparatus, an information collecting unit which collects information regarding an input state, which is determined based on the user's input, and a transition of the determined state, and a security-control unit which determines whether the user is valid based on the collected information and controls a security function. | 07-16-2009 |
| 20090278664 | RADIO FREQUENCY IDENTIFICATION (RFID) TAG ENCRYPTION METHOD AND SYSTEM USING BROADCAST ENCRYPTION (BE) SCHEME - A radio frequency identification (RFID) tag encryption method and system using a broadcast encryption (BE) scheme are provided by encrypting an ID of an RFID tag, storing the encrypted ID in a server and the RFID tag, and storing information relating to a reader authorized to read out the RFID tag in the server so that the reader can read out the RFID tag by decrypting the encrypted ID based on the encrypted ID information read from the RFID tag and the reader information. When readers read out ID data from the RFID tag, a privileged reader can read the data. Thus, it is possible to block unintended information leakage to the readers. In addition, user usability can be enhanced since an attacker cannot perform an access lock on the RFID tag. | 11-12-2009 |
| 20100162366 | APPARATUS AND METHOD OF PROTECTING PRIVATE INFORMATION IN DISTRIBUTED NETWORK - Disclosed are methods and apparatus to protect private information in a distributed network. In the distributed network, a service request terminal may receive, from a service providing terminal, trust information related to a level of trust of the service providing terminal with respect to a desired service. Also, the service request terminal may verify whether to be provided with the desired service from the service providing terminal based on the trust information, thereby preventing private information of the service request terminal from being leaked. In addition, the service request terminal may easily verify the identity of the service providing terminal when the service request terminal re-visits the service providing terminal. | 06-24-2010 |
| 20100169980 | PERSONAL INFORMATION PROVIDING APPARATUS AND METHOD - A personal information providing method and apparatus is provided. The personal information providing apparatus may extract personal information about at least one characteristic corresponding to a predetermined standard from a database storing personal information of a plurality of characteristics, embed the personal information about the at least one characteristic in a predetermined image, generate a personal information image, generate a watermark having trace information embedded, and embed the watermark in the personal information image. | 07-01-2010 |
| 20110093712 | COMMUNICATION DEVICE SUPPORTING PAIRING - Provided is a communication device. The communication device may transmit information to an external device using a terminal that makes a physical contact with the external device, and may sense the physical contact. In response to the sensed physical contact, the communication device may generate a link key. | 04-21-2011 |
| 20110179430 | Computer System and Method for Preventing Dynamic-Link Library Injection Attack - A computer system and method for preventing a Dynamic-Link Library (DLL) injection attack are provided. The computer system monitors an operation where a process attempts to dynamically link an executable code library to another process, and intercepts the dynamic link of the executable code library. | 07-21-2011 |
| 20110179490 | Apparatus and Method for Detecting a Code Injection Attack - A code injection attack detecting apparatus and method are provided. The code injection attack may be detected based on characteristics occurring when a malicious code injected by the code injection attack is executed. For example, the code injection attack detecting apparatus and method may detect that a code injection attack occurs when a buffer miss is detected, a page corresponding to an address is updated, a mode of the page corresponding to the address is in user mode, and/or the page corresponding to the page is inserted by an external input. | 07-21-2011 |
| 20110239211 | SYSTEM, APPARATUS, AND METHOD FOR DOWNLOADING FIRMWARE - Disclosed are an apparatus for downloading a firmware and an apparatus for installing the firmware. The apparatus for downloading the firmware may download an encrypted firmware in the apparatus for installing the firmware. The apparatus for installing apparatus may receive and install the encrypted firmware. | 09-29-2011 |
