Abstract:
1. A method for operating a radio frequency identification (RFID) tag, comprising: receiving a read command; determining whether a disguise state used to mislead an unauthorized RFID reader is activated based on the read command, and wherein activation of the disguise state is comprises: generating, by the RFID tag, a mode parameter, wherein the generating is performed randomly; selecting a simulation situation from a situation group according to the mode parameter, the situation group comprising a first situation, a second situation, and a third situation; and selectively generating a response signal according to the simulation situation, wherein the first situation is that the RFID tag generates a normal response signal serving as the response signal, and the normal response signal comprises virtual identity information or virtual content information stored in the RFID tag, wherein the second situation is that the RFID tag does not generate any response signal, and wherein the third situation is that the RFID tag generates a collision signal serving as the response signal to simulate a signal collision.
