On the road to the Internet of Biometric Things: A survey of fingerprint acquisition technologies and fingerprint databases

Abstract

Since security vulnerabilities represent one of the grand challenges of the Internet of Things (IoT), researchers have proposed what is known as the Internet of Biometric Things (IoBT), which mixes traditional biometric technologies with context-aware authentication techniques. One of the most famous biometric technologies is electronic fingerprint recognition, which acquire fingerprints using different technologies, some of which are more suitable for IoBT than others. Moreover, different fingerprint databases have been built to study the impact of different factors on the accuracy of different fingerprint recognition algorithms and systems. In this paper, we survey the available fingerprint acquisition technologies and the available fingerprint databases. We also identify the advantages and disadvantages of each technology and database.
