Today’s RFID protocols that govern the communication between RFID readers and tags are solely optimized for performance, but fail to address consumer privacy concerns by appropriately supporting the fair information practices. In this paper we propose a feature set that future privacy-aware RFID protocols should include in order to support the fair information principles at the lowest possible level...
This paper presents a study that has been performed in order to combine the strength of two emerging technologies: Smart Items and Enterprise Architectures. Smart Items are physical objects with sensing, computing and communication capabilities based on RFID techniques. Enterprise services are generic services that can be tailored to an industry’s or a company’s specific needs. Examples include accounting,...
In this paper, we present two methods for calibration of acceleration sensors that are inexpensive, in-situ, require minimum user interaction and are targeted to a broad set of acceleration sensor applications and devices. We overcome the necessity of orthogonal axes alignment by extending existing calibration methods with a non-orthogonal axes model. Our non-orthogonal method can furthermore be used...
Fiducial tags can be recognised successfully and decoded by computer vision systems in order to produce location information. We term a system dependable if its observable results are predictable and repeatable. The dependability of such a vision system is fundamentally dependent on the scheme used to encode data on the tag. We show that the rotational symmetry common to many tag designs requires...
