Abstract

This paper combines a study of human body morphologywith physical layer characteristics to introduce a novelbiometric identity feature for security in wearable communicationapplications. The physical layer characteristics of close fittingwearable devices are shown to vary in a unique manner throughelectromagnetic interactions between the tissue morphology andthe antenna. Experimental measurement results demonstrate thenew biometric concept using return loss characteristics to identifyindividuals on multiple body parts. An optimised directionalcoupler design is implemented with the antenna to optimize thecharacteristic feature detection range for human identification.Experiments conducted on human subjects using a prototypestandalone test-bed and sensing circuitry at 2.45 GHz, shows that,classification accuracies of over 98% are achieved for stationarysubjects and 93% for mobile subjects. The new physical layerbiometric, has the potential to be used for authentication andauthorization by using return loss as an indicator for secureuser applications, using circuitry already implemented in wirelesswearable communication systems.
