Un-killable 'Evercookie' Killed ... Sometimes

Trailrunner7 writes "The persistent method that security researcher Samy Kamkar introduced last week for storing tracking data on a user's machine, known as the 'Evercookie,' is even more worrisome when used on mobile devices, according to another researcher's analysis. The Evercookie is a simple method for forcing a user's machine to retain browser cookies by storing the data in a number of different locations. The method also has the ability to recreate deleted cookies if it finds that the user has removed them. Created by Kamkar as a demonstration of a way that sites could use to persistently track users even after they clear their browser cookies, the Evercookie has drawn the attention of a number of other researchers who have spent some time looking for methods to defeat it. A researcher in South Africa took a look at the way the the Evercookie works on both Safari on the desktop and on mobile devices, and found that it can be undone in some circumstances. However, he also found that the mobile version of Safari fares far worse in its handling of the Evercookie than the standard version does."

    I wish I had an evercookie. A magical cookie that regrows every time you take a bite out of it sounds like an amazing idea.

    A researcher from AFRICA is looking into these cookies on SAFARI! That's a great joke.

      It's this kind of blatant racism that made me move to Reddit.
