COVER STORY
to get a general sense of where people are at a given time. But, they don’t provide the full picture. With facial recognition technol- ogy, airports have access to a wide range of data points as well as a more precise view of what is happening. This can be especially important when you are looking to understand how quickly people move from one place to another.
Before AI-powered facial recognition, you had to extrapolate how quickly people moved from point A to point B by calculat- ing how many people a camera at each location captured within a given time frame. But the system didn’t know how long it took an individual to get from one place to another. Using facial recogni- tion, you can calculate how long it takes a specific person to move through the space.
CAPTURING THE REAL PASSENGER JOURNEY
The challenge here is initially capturing a high-quality reference image of an individual at the start of their journey so that the AI can then identify them again in a second camera later on. Given our world-leading accuracy and performance on live video, we are enabling customers around the world to do just that.
To illustrate, when a face passes by a camera, our platform cre- ates a biometric template, or signature, that is stored temporarily along with the time of day and camera information. When that individual’s face is captured again by another camera later during their journey, the image is then compared to the previously stored face templates. A match between the images then provides the
exact duration for that traveller’s journey.
Of course, one of the concerns around facial recognition tech-
nology is the perceived invasion of privacy. At SAFR, we under- stand this and built Privacy By Design into SAFR from the start. For this use-case, the identity of the traveller is kept anonymous as the process does not require matching their face against any databases. Individual privacy is further protected since all face images and templates are automatically deleted from the system at pre-determined intervals, usually between two and 24 hours.
IMPROVING AIRPORT OPERATIONS AND SECURITY
It’s clear that airports are complex environments that require powerful solutions to address their unique needs. They have a broad range of challenges relating to operational efficiency and security. And, with so many assets, systems, and people to safe- guard, there’s little room for error.
Our goal at SAFR is to provide the technology that gives air- ports the actionable data they need to enhance passenger expe- rience and maintain safe environments. With more data and a greater understanding, they can make better-
informed operational and management deci-
sions while also mitigating risks and respond-
ing to events and incidents more effectively.
Dan Grimm is the vice president and general manager of Computer Vision at SAFR.
