ELECTRIC TAG PERSONALIZED OF RFID TAGGED PRODUCT AND APPARATUS FOR CONSUMER PRIVACY USING IT AND METHOD THEREOF

摘要

An electronic tag for personalizing an RFID(Radio Frequency IDentification)-attached article, and a method and a device for protecting privacy by using the same are provided to prevent leakage of article and owner information, thereby enabling a user to use the tag attached to the article safely in a ubiquitous environment. A receiver(610) receives a personalization instruction and an access password. A personalizer(620) changes an electronic tag ID value storing ID information for discrimination from other electronic tags into a predetermined value and stores the electronic tag ID value to a storing part(630) by the personalization instruction. The storing part stores privacy information and the access password needed for recognizing the electronic tag ID value. A comparator(640) compares the received access password with the stored access password. A transmitter(650) transmits the ID value of the electronic tag if the received access password is identical with the stored access password, and does not transmit the ID value of the electronic tag if not.
