These days, you can't really go anywhere without encountering cameras.  Going into a store? Chances are there are security cameras. Getting money at an ATM? More cameras. Driving through the streets of a city? More cameras still. Your neighbors may have those doorbells from Amazon that are surveilling the entire neighborhood.

And many of these cameras are tied into facial recognition databases, or the footage can be quite easily compared there if "authorities" are looking for somebody.

But as it turns out, it isn't just facial recognition we have to worry about.

DHS has a new recognition system called HART.

Homeland Advanced Recognition Technology system is the alarming new identity system being put in place by the Department of Homeland Security.

DHS is retiring its old system that was based on facial recognition. It's being replaced with HART, a cloud-based system that holds information about the identities of hundreds of millions of people.
