Privacy in the Age of Persistence

Note: This isn't the first time I have written about this topic, and it
surely won't be the last. I think I did a particularly good job summarizing
the issues this time, which is why I am reprinting it.

Welcome to the future, where everything about you is saved. A future where
your actions are recorded, your movements are tracked, and your conversations
are no longer ephemeral. A future brought to you not by some 1984-like
dystopia, but by the natural tendencies of computers to produce data.

Data is the pollution of the information age. It's a natural byproduct of
every computer-mediated interaction. It stays around forever, unless it's
disposed of. It is valuable when reused, but it must be done carefully.
Otherwise, its after effects are toxic.

And just as 100 years ago people ignored pollution in our rush to build the
Industrial Age, today we're ignoring data in our rush to build the
Information Age.

Increasingly, you leave a trail of digital footprints throughout your day.
Once you walked into a bookstore and bought a book with cash. Now you visit
Amazon, and all of your browsing and purchases are recorded. You used to buy
a train ticket with coins; now your electronic fare card is tied to your bank
account. Your store affinity cards give you discounts; merchants use the data
on them to reveal detailed purchasing patterns.

Data about you is collected when you make a phone call, send an e-mail
message, use a credit card, or visit a website. A national ID card card will
only exacerbate this.

More computerized systems are watching you. Cameras are ubiquitous in some
cities, and eventually face recognition technology will be able to identify
individuals. Automatic license plate scanners track vehicles in parking lots
and cities. Color printers, digital cameras, and some photocopy machines have
embedded identification codes. Aerial surveillance is used by cities to find
building permit violators and by marketers to learn about home and garden
size.

As RFID chips become more common, they'll be tracked, too. Already you can be
followed by your cell phone, even if you never make a call. This is wholesale
surveillance; not "follow that car," but "follow every car."

Computers are mediating conversation as well. Face-to-face conversations are
ephemeral. Years ago, telephone companies might have known who you called and
how long you talked, but not what you said. Today you chat in e-mail, by text
message, and on social networking sites. You blog and you Twitter. These
conversations – with family, friends, and colleagues – can be recorded and
stored.

It used to be too expensive to save this data, but computer memory is now
cheaper. Computer processing power is cheaper, too; more data is
cross-indexed and correlated, and then used for secondary purposes. What was
once ephemeral is now permanent.

Who collects and uses this data depends on local laws. In the US,
corporations collect, then buy and sell, much of this information for
marketing purposes. In Europe, governments collect more of it than
corporations. On both continents, law enforcement wants access to as much of
it as possible for both investigation and data mining.

Regardless of country, more organizations are collecting, storing, and
sharing more of it.

More is coming. Keyboard logging programs and devices can already record
everything you type; recording everything you say on your cell phone is only
a few years away.

A "life recorder" you can clip to your lapel that'll record everything you
see and hear isn't far behind. It'll be sold as a security device, so that no
one can attack you without being recorded. When that happens, will not
wearing a life recorder be used as evidence that someone is up to no good,
just as prosecutors today use the fact that someone left his cell phone at
home as evidence that he didn't want to be tracked?

You're living in a unique time in history: the technology is here, but it's
not yet seamless. Identification checks are common, but you still have to
show your ID. Soon it'll happen automatically, either by remotely querying a
chip in your wallets or by recognizing your face on camera.

And all those cameras, now visible, will shrink to the point where you won't
even see them. Ephemeral conversation will all but disappear, and you'll
think it normal. Already your children live much more of their lives in
public than you do. Your future has no privacy, not because of some
police-state governmental tendencies or corporate malfeasance, but because
computers naturally produce data.

Cardinal Richelieu famously said: "If one would give me six lines written by
the hand of the most honest man, I would find something in them to have him
hanged." When all your words and actions can be saved for later examination,
different rules have to apply.

Society works precisely because conversation is ephemeral; because people
forget, and because people don't have to justify every word they utter.

Conversation is not the same thing as correspondence. Words uttered in haste
over morning coffee, whether spoken in a coffee shop or thumbed on a
BlackBerry, are not official correspondence. A data pattern indicating
"terrorist tendencies" is no substitute for a real investigation. Being
constantly scrutinized undermines our social norms; furthermore, it's creepy.
Privacy isn't just about having something to hide; it's a basic right that
has enormous value to democracy, liberty, and our humanity.

We're not going to stop the march of technology, just as we cannot un-invent
the automobile or the coal furnace. We spent the industrial age relying on
fossil fuels that polluted our air and transformed our climate. Now we are
working to address the consequences. (While still using said fossil fuels, of
course.) This time around, maybe we can be a little more proactive.

Just as we look back at the beginning of the previous century and shake our
heads at how people could ignore the pollution they caused, future
generations will look back at us – living in the early decades of the
information age – and judge our solutions to the proliferation of data.

We must, all of us together, start discussing this major societal change and
what it means. And we must work out a way to create a future that our
grandchildren will be proud of.
