ABSTRACT:
A method, comprising: obtaining a signature from a contactlessly readable tag; decrypting the signature with a key to obtain (i) a candidate identifier and (ii) a scrambling code associated with the signature; and validating the candidate identifier based on at least one of the scrambling code and the signature. Also, a system, comprising: at least one tag reader configured to receive a plurality of signatures released by a respective plurality of tags, including a particular signature released by a particular one of the tags, and to cause decryption of the particular signature with a key to obtain (i) a candidate identifier, and (ii) a scrambling code associated with the signature; and a processing entity configured to effect validation of the candidate identifier based on at least one of the scrambling code and the signature.
