DEVICE AND METHOD FOR CHECKING THE INTEGRITY OF PHYSICAL OBJECTS

摘要

The device (9) has memory elements i.e. radiofrequency identification (RFID) tags (5), attached to physical objects i.e. baggage. A controller (15) executes a reading function capable of cooperating with TV readers (13) to acquire data in the near memory elements. The controller executes an integrity validation function capable of differentiating secret key type individual identifiers and group description data in the acquired data for verifying the adequacy of the description data, while verifying the conformity of the identifiers against the corresponding description data.
