DATA PROTECTIVE RADIO-FREQUENCY IDENTIFICATION (RFID) SYSTEM BY MEANS OF AN OWNER CONTROLLED RFID-TAG FUNCTIONALITY

摘要

The invention relates to a RFID-tag comprising a) a transmitting device (4) and a receiving device (3) for data produced by a reading device (2), b) in particular a memory (5) of identification data clearly characterising the RFID-tag, c) a control unit for automatically executing functions according to the fact that the reading device (2) detects the knowledge of an internal password in the internal password (6) memory and/or authorises the function execution on the basis of information stored in the internal state (7) memory and d) a modification unit for modifying the internal password stored in the memory and/or the internal state, in particular depending on a preceding comparison of the internal password with the password received by the reading unit (2). A method for using said RFID tag is also disclosed. Said invention solves the above mentioned privacy problem of a RFID technology and makes it possible in a known kill function difference the further use of said technology for optionally networked intelligent devices provided with the inventive RFID tag.
