Abstract
Provided is a Radio Frequency identification (RFID) system and method for protecting information. The system includes: an identification information storing unit which includes identification information and generates an interrupt/interference signal to block access without permission; an RFID calling unit which reads information of the identification information storing unit by loading a basic protocol and a security protocol for recognizing the identification information storing unit; and a storing unit which registers and stores information required for authentication between the RFID calling unit and the identification information storing unit, and information required for access control.
