Ross Anderson discusses the threat of intrusive surveillance on the web.
Twenty years ago, I could find everything about you that was on the World Wide Web, and you could do the same to me, so there was mutuality. Now, if you’re prepared to pay the money and buy into the advertising networks, you can buy all sorts of stuff about my clickstream, and find out where I’ve been staying, and what I’ve been spending my money on, and so on. If you’re within the tent of the intelligence agencies, as Snowden taught us, then there is very much more still. There’s my location history, browsing history, there’s just about everything.
This is the threat. This was a threat before Mr. Trump got elected president. Now that Mr. Trump has been elected, it must be clear to all that government having very intrusive powers of surveillance is not something that necessarily sits well with a healthy democratic sustainable society.
