Protection of non-promiscuous data in an RFID transponder

摘要

A radio frequency identification device (RFID) and method for authenticating RFIDs are disclosed. In RFIDs, data is stored in a form of data segments selectively associated with promiscuous and non-promiscuous regions of their memories. A randomly selected portion of a content of a non-promiscuous region is examined by an interrogating readers or a host computer after validating the data contained in a promiscuous region.
