Abstract
Disclosed is an RFID tag for protecting information and a method for protecting personal information. The RFID tag for protecting information includes an encoder for simultaneously outputting first and second signals so as not to allow the RFID reader to distinguish respective RFID tags from each other in accordance with an information request signal from an RFID reader, a modulator for modulating the first and second signals output from the encoder, and first and second antennas respectively for outputting the modulated first and second signals. Therefore, personal information can be protected by preventing the information of the respective RFID tags from being read by unauthorized RFID.
