Abstract
A method used to authenticate an item using an identification tag is provided. At the time of manufacture, the tags are created with various hardware attributes (HA), including a unique identifier (UID); and encoded with a signature of a message that includes a URL, and optionally a serial number associated with a product to which the tag is to be attached. The URL embeds various data such as one or more of the HAs, a serial number, etc., which can be used to verify the authenticity of the tag when verifying the signature. When a tag is read, the message including the URL is recovered and the signature is verified by the processor of the reader. This can be done to ensure that the URL in the message is one designated by the signer. The data in the signature can then be used to verify the authenticity of the tag and/or to detect tampering. The results of the verification can also be displayed to a user, e.g., using an available display on the electronic device including or otherwise acting as the tag reader.
