From Cory Doctorow's 11-2-17 Boing Boing post entitled "The DHS Is Buying a New Database to Store Biometrics for 500 Million People":
DHS's old 'IDENT' database is full, with 240,000,000 records in a
system designed to hold 200,000,000; so they're paying arms-dealers and erstwhile comic-book superheroes Northrop
Grumman $93,000,000 to develop a new system called Homeland Advanced
Recognition Technology (HART), which will grow to encompass biometrics
for 500,000,000 people, including hundreds of millions of Americans."
