Secure Access to Buildings using RFID Technologies and Video Logging
Recent developments give RFID technology the power to engulf day-to-day aspects of common life. The emergence of globally standardized frequencies and protocols, coupled with the rapidly declining cost of hardware, make RFID a technology that will pervade many aspects of modern life. It is widely accepted that current applications that work on infra-red bar codes will be completely taken over by RFID. Similar, secure access via RFID is a much more user-friendly authentication mechanism as compared to magnetic swipe cards (e.g. as currently used at CMU). Meanwhile, digital cameras and storage systems are increasingly becoming cheaper and more sophisticated. The goal of this proposed project is to build on our earlier effort called RFMaster with previous CyLab support to prototype a scalable tracking, logging and notification system for people and objects built using RFID, digital cameras and storage technologies. The system is aimed at enabling access to physical spaces such as buildings and rooms across campuses, corporate offices and warehouses.
The system comprises of the following subsystems:
The overall system design is given below. The RFID readers will include both short-range and medium-range readers, the former for tracking people and the latter for tracking objects. and will be able to handle the presence of multiple tags at the same time. We also plan to extend this infrastructure to track people in public environments such as museums where custom information based on their location must be streamed to them.
Version 1.0 of RFMaster which uses only short-range RFID readers is available on the CyLab for download and use by CyLab partners. We have also participated in CyLab partner meetings including making presentations and posters. We envision such RFID and camera-based surveillance systems as becoming an integral part of scalable sensor networks which also measure physical variables such as temperature, pressure, light and sense events such as fire. This latter effort is funded through other non-CyLab projects.
We request a total budget that supports 1 graduate student, and $10.000 for equipment (RFID medium-range readers each of which costs about $5600 and two PCs).
