Liberty Defense Advances Proprietary AI Algorithm for its HEXWAVE Security Detection System

Company provides update on significant product and technology progress made in preparation for field beta testing and commercialization of HEXWAVE’s detection of concealed weapons and threats

Wilmington, MA, – April 5, 2022 – Liberty Defense Holdings Ltd. (“Liberty” or the “Company”) (TSXV: SCAN, OTCQB: LDDFF, FRANKFURT: LD2), a leading technology provider of detection solutions for concealed weapons and threats, is pleased to announce that it has begun amassing thousands of images required to train its newly-developed Artificial Intelligence (AI) software algorithms to accurately identify metallic and non-metallic concealed weapons or threat objects on a person, clearing the path to meet and exceed robust detection and screening performance requirements across multiple markets.

“With our collection of real-world data from our proprietary HEXWAVE hardware portals, Liberty has reached a critical milestone on its development path to bring advanced security detection to the market,” says Liberty President & CTO Michael Lanzaro. “We have been developing a cutting-edge deep learning algorithm with our team of industry experts, who have previously and successfully brought to market industry-leading AI algorithms used in the aviation security screening market. And, with the hardware configuration recently completed on the first two beta HEXWAVE portals, we are confident we now have an imaging platform that can deliver high-quality image data to enhance our AI algorithm.”

HEXWAVE uses millimeter wave, advanced 3D imaging, and AI to detect all types of concealed metallic and non-metallic weapons and other threats. The system allows for rapid, automated screening using a high throughput, contactless, walkthrough portal without compromising the patron or passenger experience. It can be used as either a checkpoint solution, or to enhance current systems and provide layered defense at indoor and outdoor locations for early threat detection in preventing violent crime and mass casualties.

Liberty has successfully demonstrated the HEXWAVE system’s detection capability and currently has collaboration agreements in place for beta trials at an international airport, a top-ranked US state university, a Hindu place of worship, and a sporting venue for MLB and NFL teams.

The Company is currently in the process of collecting data comprised of over 25,000 images leading up to field beta trials this summer that will include testing an expansive list of metal and non-metal threats that customers are looking to detect (see figure below) while ensuring that benign items such as keys, wallets, and mobile phones left in pockets do not trigger alarms requiring a secondary inspection.

“HEXWAVE uses real-time video-rate image capture as each subject advances through the portal, which is unlike the airport screening process where individuals are required to pose and remain still while being scanned. HEXWAVE provides a significant advantage as it enables continuous movement of people through the portal at high throughput rates without having to divest personal items and without negatively impacting detection performance. Our AI platform takes advantage of the multiple radar images taken at various angles as a person proceeds through the system, allowing for many more opportunities to see and detect threats,” added Lanzaro.

Images generated are used internally by the HEXWAVE system and never stored or seen by an operator. The system is safe for public use and recently cleared by the FCC for testing.

In other news, Liberty’s CEO Bill Frain will be presenting at the Technology Virtual Investor Conference, Thursday, April 7, 2022, at 11 am ET to discuss the Company’s plans to bring next generation security detection to market. The presentation will be made available on Liberty’s website.
