Criminal Fishing System Based on Wireless Local Area Network Access Points - Can Media Access Control address assist criminal investigation?

This paper describes a system for criminal identification that utilizes a large number of wireless local area network (LAN) access points and cameras. The proposed “Criminal Fishing system” identifies the media access control (MAC) address of a culprit's device from probe request signals captured by access points during the period in which a culprit remains near the incident scene. Experimental results demonstrate that the proposed system could identify the culprit MAC address 10 out of 10 times in an indoor experiment and 8 out of 8 times in an outdoor experiment, in case that the culprit's radio wave fingerprint could be captured.
