Browsers leave fingerprints

New research by the EFF suggesting that most browsers create a unique signature that can be used as a means of identification.

The findings were the result of an experiment EFF conducted with volunteers who visited http://panopticlick.eff.org … EFF found that 84% of the configuration combinations were unique and identifiable, creating unique and identifiable browser “fingerprints”. Browsers with Adobe Flash or Java plug-ins installed were 94% unique and trackable.
