Aspects of Biometric Security in Internet of Things Devices

This chapter provides detailed insight into the general mechanisms utilized for biometric application in Internet of things devices. The mechanisms and internal working of these biometric technologies presented in this chapter are focused specifically on the applicability in IOT devices. IOT devices incorporates various scanners and sensors to allow the IOT device to biometrically interact with a human being. These scanners and sensors were primary designed to facilitate and ease user interaction with the IOT device in an effort to make the day to day usability of the IOT device faster and easier if you may. It must be noted that every biometric technology has certain strengths, but indeed, also certain noteworthy shortcomings. It is often these shortcomings that get exploited in a security subversion attempt. This chapter introduces and discusses the various biometric technologies used in IOT devices. Attention is given to the software and the hardware aspects of each biometric system. The generic working of these biometric technologies is presented. Attention is given to legacy biometric technology implemented on IOT devices, currently used biometric technology implemented on IOT devices, and finally, possible future biometric applications of biometric technology destined for IOT devices. In conclusion practical examples of biometric subversion on IOT devices such as fingerprint, facial and voice biometric subversion and hacking, will be investigated, discussed and evaluated.
