Schneier on privacy and data toxicity

Bruce Schneier has been writing eloquently about privacy again.
"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...

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."
