Abstract

Electronic tags such as 2D bar codes and NFC are used to connect physical and virtual worlds. Beyond pure information augmentation of physical objects, this gives rise to new user interfaces, so called multitag interfaces. A salient feature of these interfaces is that the user sees a physical object, a poster, but interacts with its electronic augmentation. We present two attacks that exploit this feature along with first thoughts of how these attacks may be countered. We analyze the possibility to introduce secure bindings into these novel user interfaces.
