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.

It might also depend on your browser version, you graphic card drivers version and other software components.

And then you can add other signals like the list of extensions you have installed, your geolocation and so on. Every signal makes you a little bit more unique.

I guess I can just see why this is possibly being abandoned. People who frequent OSNews probably vary wildly for combinations of software and hardware, but we represent a small pool of users. The masses of homogeneous Apple (and other desktop mass market manufacturers) hardware paired with a lot of people who simply use what's installed by default to shop on ebay, browse facebook, or watch youtube (amongst other video providers *ahem*) I just cant see this being THAT useful.

If geotagging is the only variable identifying my MacbookPro from every other MacbookPro, then just use the geotagging and ignore the extra stuff.
