Abstract

Radio Frequency Identification (RFID) has gained a lot of attention lately with the introduction of RFID tags or inlays for a variety of applications. Most common is location tracking which can further be used for detecting the movements of tags from their original positions. In order to develop a system for finding the change in tag positions, a correct combination of RFID tags and reader is vital. Also, better understanding of challenges facing the RF signal can be productive. Environmental factors, antenna radiation pattern and orientation are some key issues, which can undermine this approach. In this thesis, to address some of the challenges a security algorithm for indoor RFID systems is proposed for detecting the change in the tag positions by finding the change in inter-tag distance. Also, several measures have been used to overcome the random nature of the RF signal. Experiments and evaluation of the above-mentioned methods in real time prove the robustness of the techniques considered for providing security.
