Abstract
An electronic tag for protecting privacy in RFID and a method of protecting privacy using the same are provided. Specifically, an RFID electronic tag capable of protecting privacy by authenticating an RFID reader and controlling access of the RFID reader to the RFID tag and a method of protecting privacy using the same are provided. The RFID electronic tag is applicable to a passive type RFID tag. The RFID electronic tag is also applicable to an ISO/IEC 18000-6 Type C tag that is a typical passive type RFID tag. It is possible to protect privacy of a user by controlling access of the RFID reader to the RFID tag and authenticating the RFID reader by modifying a tag inventory protocol and a memory map of the tag.
