Abstract: The connection between real people and the MAC of the communications device is of high value to public and network security. A better solution was proposed to improve the existing methods. MAC and real-time RSSI changes of the communication device were obtained by multiple Wi-Fi probes, then the RSSI status change sequence was constructed. The distance between object and multiple Wi-Fi probes was obtained by the object tracking, and the sequence of distance state change was constructed. After two kinds of sequences were compared, the optimal result was selected as the matching result between the moving object and the MAC of the mobile device. Experiments demonstrate that the method is more versatile and more accurate than other methods.

Key words: MAC address matching, object tracking, RSSI(Received Signal Strength Indication), Kalman filter
