In the Border Control Process, fingerprints are being used to perform identity verification (i.e. inspect travellers’ identity), based on fingerprintes stored on electronic travel document or databases (i.e. the Visa Information System), and thus allows for precise and fast identification of travelers. AIT tried to look at how fingerprint identification systems can be improved to better support the tasks of a border guard.
Available technologies for fingerprint acquisition can be divided into contact-based (capacitive, ultrasonic, thermal and optical sensors) and contact-less sensors (optical). Each technology has its benefits, but especially the BCP the introduction of contact-less optical technology would yield a great benefits. Contact-less optical sensors can be made very durable and do not require much maintenance, both equally important in high-throughput scenarios like airports. Furthermore, since the fingerprints are being read from a distance, no latent fingerprint will be on the sensor, and also improves hygiene in such a scenario. The sensors can also be made resistant to shock and extreme weather, allowing them being used in a mobile scenario. Within the BODEGA project, AIT developed a 4 finger print scanner OTF with sunlight immune auto trigger, distance detection, automatic best shot selection, auto NFIQ 2 quality assessment, automatic sharpness detection and control with 30 fps and auto hand side detection, auto finger detection, all with no moving parts. Since it allows for the capture of multiple fingers, the technology is also future-proof. To show its versatility, the sensor had also been integrated into a stationary access control solution. The following video shows the newly developed sensor in action:
