Autonomous authentication of a reader by a radio frequency identity (RFID) device

A radio frequency identity (RFID) tag, comprising:

• a logic processor;
• a memory, wherein the memory comprises biographical information about an object to which the RFID tag is one of coupled or adhered and a plurality of authentication codes corresponding to a plurality of authentication tokens of tag readers to which the RFID tag is configured to transmit the biographical information, and wherein the biographical information comprises static information about an initial state of the object and dynamic information about a current state of the object;
• a radio transceiver configured to receive a request signal for the biographical information from an RFID reader and to transmit a reply to the request signal for the biographical information;
• and
• an application stored in the memory of the RFID tag that, when executed by the logic processor:
• parses a request signal from a tag reader to extract an authentication token from the request signal,
• analyze the authentication token to determine whether the tag reader is authorized to receive biographical information stored in the memory of the RFID tag by comparing the authentication token to the plurality of different authentication codes stored in the memory of the RFID tag,
• determine whether the tag reader is authorized to receive the biographical information based on the comparison, wherein the tag reader is authorized to receive the biographical information when the authentication token matches one of the plurality of different authentication codes stored in the memory of the RFID tag,
• in response to a determination that the tag reader is authorized, reads the biographical information from the memory and sends the biographical information to the radio transceiver to transmit to the tag reader, and
• in response to a determination that the tag reader is not authorized to receive the biographical information, reads one of a null value or a tag identity (TID) and sends the one of the null value or the TID to the radio transceiver to transmit to the tag reader.
