Fingerprinting WiFi Could Secure MAC Addresses

Carleton University researcher Dr. Jeyanthi Hall has developed a new method that could end MAC address spoofing. Based on her radio frequency signal analysis for 15 devices, Hall found out that variations during the manufacturing process creates a unique signal for each of these devices. The signals were so distinct that she was able to attain a 95 percent detection rate with no false positives during the trial.
