ABSTRACT:
An identification tag for authenticating a product is associated with the product and has authentication data transmissible to a reader device. The authentication data include source data including a tag identifier that uniquely identifies the identification tag and a signature value that is a result of a private key encryption of a representation of the source data, where the private key encryption uses a private key of a public key encryption method.
