Introducing the Invulnerable Evercookie
An anonymous reader writes "Using eight different techniques and locations, a 'security' guy has developed a cookie that is very, very hard to delete. If just one copy of the cookie remains, the other locations are rebuilt. My favorite storage location is in 'RGB values of auto-generated, force-cached PNGs using HTML5 Canvas tag to read pixels (cookies) back out' — awesome."
If you have to go to great lengths to work around customers doing things like deleting cookies then you are doing something wrong or evil.
Keep the Classic Slashdot.
it's not his research either. this has already been observed in the wild and already reported by ars technica.

the advertisement company got already sued for it.
symlink the LSO folder to /dev/null
90% of everything is crap. Also, crap is relative.
who doesn't know what a cookie is probably won't be affected by this in any way (i.e. they're already being tracked through regular cookies).
There's all kinds of databases on people available. Search and you shall find.
All data circulates easily and is simply very hard to stop. It is indeed like speech, it just happens, anyone can do it. Copyrighted data, personal data, credit data, secret data, whatever. Bottom line, gathering and selling various gray-black-market data is illegal immoral etc, and very doable and very interesting for companies and organizations of all types. Not unlike downloading movies is for many - illegal but easy and interesting data. It's the interests that are different.

Rather than disabling and trying to defeat all these tracking mechanisms I think it would be easier to flood them with false information. Someone should set up a cookie sharing site and FF extension that trades (safe, non-identifying) cookies amongst all the users of that extension. Why yes, I did visit mylittlepony.com directly between visits to journalofparticlephysics.edu and horsesluts9.com, why do you ask?
