MedAssist - A privacy preserving application using RFID tags

Privacy is an important aspect in the Internet of Things (IoT). We see the provision of privacy preserving mechanisms as one enabler for this technology (above all because of the public acceptance). Privacy means, that a user has control over the access to its data. In this work we want to present a medical application which uses passive RFID tags on pharmaceuticals to provide special services for the user. We consider this information as sensible and developed a system where the user has the full control over the access to this data. For our protocol we use standardized cryptographic primitives which are suitable for passive RFID technology. Our protocol provides data privacy as well as transfer of ownership.
