It is something few Americans will have likely heard of, but the US Department of Homeland Security’s Homeland Advanced Recognition Technology (HART) is catching the eye of privacy advocates – and not in a good way.

Announced in 2017, on the face of it HART is just a bigger and better version of the DHS’s Automated Biometric Identification System (IDENT), which dates back to the 1990s, before the DHS even existed.

IDENT was built to gather data such as fingerprints and photographs of people entering the US – anyone who’s visited the country as a non-US citizen in the last 15 years or so will be in this database.

Despite sounding similar, HART marks a step change in what such databases can be used for when combined with emerging technologies such as real-time facial recognition and biometrics.
