Most people are now fully aware of how much tracking is going
on when you go online, and how easy it is for companies and governments to know
where you go, what you do there, and who you talk to. But meanwhile, another
piece of technology has slowly started being adopted by organizations all over
the world, and is still relatively unknown by most people, yet could be the key
to bringing the type of surveillance state that we currently experience online,
to the offline world.

Let me give you a little anecdote of something that happened
to me last month. I walked into a local bank branch near where I live in
Montreal, a bank where I don’t have any account, and never interacted in any
way, in order to ask about some investment products. I get directed to one of
the staff members and I talked to her for about 10 minutes, never saying my
name or giving her any way to identify me. I ended up not being interested in
what she was offering and walked away. But as I did, the last thing she said
was “Au revoir, Mr. Lambert.” That’s nice but how did she know who I
was, despite the fact that I never gave any hint of my identity?

I didn’t think much of it at the time, but after getting back
home I did some research and found articles from a few years back about some
banks here in Canada contracting with a company to provide them with facial
recognition cameras. Going over the incident in my head, this seems like the
most likely explanation. Now one argument people could make is that banks
already have cameras, lots of them, and so do stores and buildings all around
our modern towns. But I would argue that facial recognition brings this to a
whole new level. What we’re basically seeing is the same thing that happened
years ago with phone calls.

Back in the day, when you picked up a telephone and placed a
call, it would go along an analog circuit and the wire would need to be physically
plugged in. We knew it was possible for someone at the central office to listen
in, but the chance was remote, and there was no way they could start listening
to every phone call as they went on. This is the same way normal cameras
function. The best refinement the industry has managed to do is divide several
cameras into a single screen, and then place multiple screens in front of a
single security guard. But facial recognition completely changes the rules of
the game. Now, we have software programs able to recognize anyone who walks by
instantly, and record that in a database.

Facial recognition systems can work in a number of ways. The
traditional system uses a standard camera and software that can compare some
features of your face to a database of photos. By looking at the size of your
nose, your eye position, or the slope of your jaw, it may be able to figure out
who you are. A newer and much more reliable way to do facial recognition is to
use multiple cameras and do a 3D comparison. This way, many more features of
your face can be compared with what’s in the database. Finally, some systems
can even identify skin patterns such as lines, moles, spots and other
characteristics found on most faces.

But how widespread is it really? This technology is nothing
new. Back in 2004 the US State Department began implementing a huge facial recognition system
for visa applicants. The New York Times reported last month
that the Department of Homeland Security is in the final stages of developing such a
system as well. The FBI is also spending over $1 billion on its own facial
recognition system. Recently, it was revealed that the Attorney General of Ohio already implemented such a system back in June,
without telling anyone. The system relies on 10 years of information from driver’s
licenses, gun permit holders, known criminals, sex offenders and more, all
stored in a central database. The technology is also widely used in advertising.
This video is just one
such system which can access 36 million users within 1 second.

So we know the technology exists, and has become very refined.
We also know corporations and governments are hard at work to implement it for
their own purposes. The problem is that as with most things in technology, the
law is lagging behind. There is no legal framework as to how facial recognition
can be done. We’re all used to seeing cameras everywhere we go, but the
question that needs to be answered sooner rather than later is whether we’re
alright with these cameras automatically identifying us, recording everywhere
we go, and then acting on this information, providing anything from
personalized ads on a nearby billboard to a complete tracking profile at your
local government office.

Have you had any experience implementing or using this kind of software?
