Video fingerprinting for border control sees $25,000 award

Video fingerprinting for border control sees $25,000 award from KiwiNet Emerging Innovator Fund

HAMILTON, NZ. – 29 March, 2017 – Innovative research on video fingerprinting for border control scanning has resulted in a $25,000 KiwiNet grant for Victoria University of Wellington research scientist Dr Nick Monahan. The grant from the KiwiNet Emerging Innovator Fund, to help nurture innovative new ideas from scientists and support early stage prototype and market development, is one of fifteen made possible by donations from the Norman F. B. Barry Foundation.

The grant is enabling Dr Monahan, with a PhD in ultrafast spectroscopy, to develop a prototype handheld device that can rapidly scan passengers and other items in real time to identify prohibited items.

“Our scanning technology uses compact low powered lasers to leverage a portion of the electromagnetic spectrum known as terahertz (THz) radiation to generate ‘fingerprints’. These allow border authorities to identify organic substances that X-rays cannot,” he says.

Dr James Hutchinson, CEO of KiwiNet says, “The increased volume of international passengers, mail and cargo moving between borders presents challenges for border authorities, and creates an opportunity to streamline the border security process with new innovative technology. We’re pleased to support Dr Monahan’s quest to solve this significant industry challenge.”

According to Dr Monahan, existing scanning equipment used for border control is both large and expensive. “The goal is to make video camera technology that uses terahertz radiation, which in this case, is a bit like X-rays in that it can see through packaging and bags to identify prohibited items. The pixels in the terahertz pictures and videos we generate contain fingerprints that record how a material absorbs different wavelengths in the THz spectrum.”

Dr Monahan is building a fingerprinting database to identify small carbon based molecules found in prohibited pharmaceuticals and explosives. The database will be tailored to meet the needs of different border authorities and trigger alerts when target items are scanned.

Dr Monahan says the fingerprinting is incredibly powerful when combined with imaging. “When we scan a dry bag with items in it that absorbs a lot of THz radiation it might mean that it contains fruit or vegetables. If it contains an orange, then an image of the bag will show a circular area of strong THz absorption signalling to border control staff that a bag, parcel or person needs to be inspected more closely.”

Associate Professor Justin Hodgkiss, Principal Investigator of the Ultrafast Laser Spectroscopy Group at Victoria University of Wellington, says, “Spectral imaging in real time is very difficult: it requires extracting a lot of information from a very weak signal. Dr Monahan’s technology is quicker at detection without compromising sensitivity.”

Dr Anne Barnett, General Manager of Commercialisation at Viclink, Victoria University of Wellington's commercialisation office, nominated Dr Monahan to receive KiwiNet Emerging Innovator funding, and Viclink is continuing to provide commercialisation support.

Ministry for Primary Industries (MPI) was also identified as an ideal proof of concept industry partner. Dr Desi Ramoo, Research and Innovation Practise Lead at MPI says, “MPI’s support for Dr Monahan’s prototyping demonstrates our desire to provide MPI staff with world leading technology developed by New Zealand’s innovative science community. We’ve identified a range of substances that we’re interested in for Dr Monahan to fingerprint. We’ve also highlighted real world applications so his prototype can better meet the needs of both our border authority and others around the world.”

The project additionally received $25,000 KiwiNet PreSeed funding and matching funding from Viclink. This was combined with funding from MPI in order to extend the length of the project and enable the development of a more robust prototype.

The KiwiNet Emerging Innovator Fund is available to early career researchers based at universities and Crown Research Institutes across New Zealand. The fund is designed to boost research with a commercial application at a critical time. It also enables researchers to partner with a business and refine their project for market. Recipients also receive expert legal advice from KiwiNet ( corporate partners, MinterEllisonRuddWatts and IP advice from Baldwins.

Norman F. B. Barry Foundation Chairman John Smith says, “It’s great to see our donation help yet another enterprising young researcher develop a proof of concept prototype.”

Dr Monahan says, “I’m very grateful to the Foundation and to KiwiNet as their support has been critical in the development of this technology. I’m also developing invaluable skills not usually developed as a scientist like communicating science and pitching ideas.”
