Don't Track Me, Bro

Here's the latest from the world of cybertracking your web browser:

A new, extremely persistent type of online tracking is shadowing visitors to thousands of top websites, from WhiteHouse.gov to YouPorn.com.

First documented in a forthcoming paper by researchers at Princeton University and KU Leuven University in Belgium, this type of tracking, called canvas fingerprinting, works by instructing the visitor’s Web browser to draw a hidden image. Because each computer draws the image slightly differently, the images can be used to assign each user’s device a number that uniquely identifies it.

YouPorn quickly turned around and announced they they were "completely unaware that AddThis contained a tracking software that had the potential to jeopardize the privacy of our users," and that they'd stopped using it. No such announcement came from the White House.
