Tag Broker Model to protect privacy?

This paper is quite technical to comprehend. Nevertheless, it sounds interesting as to how such a model has been proposed to protect privacy within an RFID enabled setting. Briefly, this article discusses on such a tag broker model approach for an enabled Mobile RFID which is compatible with Near Field Communication (NFC). I am wondering whether is there any literature that touches on data protection and privacy issues in relation to NFC? Reason being: NFC, is an industry standard that results to the technical compatibility and operability, deriving from RFID. Or, maybe, it's a subset of RFID as well? Pondering.
