An embedded access control system for restricted areas in smart buildings

This paper presents an embedded system for access control in restricted area through the integration of two authentication strategies: facial recognition and RFID TAGs. Once face recognition, in an embedded system, is susceptible to failures, the integration with RFID tags aims to increase the robustness of access control system. This system can be easily deployed into enterprise environments, meetings and offices rooms. Additionally the proposed system does not require an Internet access. Through the evaluations we observed an acceptable execution time and this integration yields an increase of robustness of access control system, even using simple techniques of face recognition.
