Here is an interesting report on an experiment in anonymous living. Catherine Price writes in Popular Science about attempting to hide every aspect of her daily life for seven days. The article also provides a good review of the privacy situation in the U.S., and the ubiquity of commercial surveillance.
The Anonymity Experiment | Popular Science
We don’t know what information is being collected about us, whom it’s
being shared with, what it’s being used for, or where it’s being held.
As companies and the government collect more and more data on us, some
of it will inevitably be incorrect, and the effect of those errors
could range from trivial to severe. It’s not a big deal to get coupons
for products you don’t want, but if a mistake in your file or an
identity theft caused by a data breach drives down your credit score,
you could find yourself knocked into the subprime-mortgage market. And
privacy-invading safeguards don’t just catch bad guys. Anyone could end
up like Senator Ted Kennedy, who was erroneously placed on a do-not-fly
list because a terrorist had once used the alias “T. Kennedy.”
