1. A method for determining validity of an RFID tag comprising:
- probing the tag using a series of tag commands to trigger a corresponding series of tag responses;
comparing the tag responses to tag reference data stored in a database;
repeating the steps of probing and comparing to determine the validity of the tag.

Abstract
A method for determining validity of an RFID tag. The method includes probing the tag using a series of tag commands to trigger a corresponding series of tag responses, comparing the tag responses to tag reference data stored in a database, and repeating the probing and comparing operations to determine whether or not the tag is valid.

2. A method for determining validity of an RFID tag comprising:
-
storing, in a reference database, a tag fingerprint including attributes for a specific type of RFID tag; including the tag fingerprint in contents stored in a specific RFID tag; reading the contents stored in a selected RFID tag; determining whether the selected RFID tag is a valid specific type of RFID tag by comparing the tag fingerprint in the contents read from the selected RFID tag with the attributes for the specific type of RFID tag stored in the reference database. - View Dependent Claims (3, 4)

5. A method for determining validity of an RFID tag comprising:
-
storing, in a reference database, a tag fingerprint including attributes for a specific type of RFID tag, wherein the tag behavior comprises responses, from the tag, to a specific sequence of commands sent to the tag; including the tag fingerprint in a digital signature performed over contents stored in a specific RFID tag; reading a selected RFID tag; and determining whether the selected RFID tag is a valid specific type of RFID tag by comparing the tag fingerprint in the contents read from the selected RFID tag with the attributes, for the specific type of RFID tag, stored in the reference database. - View Dependent Claims (6, 7, 8)

9. A method for determining validity of an RFID tag comprising:
-
storing, in a reference database, a tag fingerprint including indicia of tag behavior indicative of a specific type of RFID tag, wherein the tag behavior comprises responses, from the tag, to a specific sequence of commands sent to the tag; including the tag fingerprint in a digital signature performed over contents stored in a specific RFID tag; reading a selected RFID tag; and determining whether the selected RFID tag is a valid specific type of RFID tag by comparing the tag behavior of the selected tag with the indicia of tag behavior, for the specific type of RFID tag, stored in the reference database. - View Dependent Claims (10, 11, 12)

13. A method for determining validity of an RFID tag comprising:
-
storing, in a reference database, a tag fingerprint including attributes for, and indicia of tag behavior indicative of, a specific type of RFID tag, wherein the tag behavior comprises responses, from the tag, to a specific sequence of commands sent to the tag; including the tag fingerprint in a digital signature performed over contents stored in a specific RFID tag; reading a selected RFID tag; and determining whether the selected RFID tag is a valid specific type of RFID tag by; comparing the tag fingerprint in the contents read from the selected RFID tag with the attributes, for the specific type of RFID tag, stored in the reference database; and comparing the tag behavior of the selected tag with the indicia of tag behavior, for the specific type of RFID tag, stored in the reference database. - View Dependent Claims (14, 15)
