“…Therefore, they can perform differently (e.g return loss) even when placed at the same location on the same human [20]. This variance is further compounded if the human changes their body position [21].…”

This paper combines a study of human body morphology with physical layer characteristics to introduce a novel biometric identity feature for security in wearable communication applications. The physical layer characteristics of close fitting wearable devices are shown to vary in a unique manner through electromagnetic interactions between the tissue morphology and the antenna. Experimental measurement results demonstrate the new biometric concept using return loss characteristics to identify individuals on multiple body parts. An optimised directional coupler design is implemented with the antenna to optimize the characteristic feature detection range for human identification. Experiments conducted on human subjects using a prototype standalone test-bed and sensing circuitry at 2.45 GHz, shows that, classification accuracies of over 98% are achieved for stationary subjects and 93% for mobile subjects. The new physical layer biometric, has the potential to be used for authentication and authorization by using return loss as an indicator for secure user applications, using circuitry already implemented in wireless wearable communication systems. Index Terms-biometric, antenna characteristics, return loss, directional coupler, wearable antenna, physical layer security.
