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.

Advertising companies will become increasingly... 'Creative' to find some way of tracking us that circumvents known laws and technological barriers. However, I doubt you have to worry about the small fish - worry about what the biggest internet advertising company in the world has cooking in its labs.
