Flash cookies

Flash can be a great technology in the right hands; in the wrong ones, it can be used for some rather questionable ends. This Wired News article on Flash cookies observed that "More than half of the internet's top websites use a little known capability of Adobe's Flash plug-in to track users and store information about them, but only four of them mention the so-called Flash Cookies in their privacy policies:"

Unlike traditional browser cookies, Flash cookies are relatively unknown to web users, and they are not controlled through the cookie privacy controls in a browser. That means even if a user thinks they have cleared their computer of tracking objects, they most likely have not.

What's even sneakier?

Several services even use the surreptitious data storage to reinstate traditional cookies that a user deleted, which is called 're-spawning' in homage to video games where zombies come back to life even after being "killed," the report found. So even if a user gets rid of a website's tracking cookie, that cookie's unique ID will be assigned back to a new cookie again using the Flash data as the "backup."

Adobe explains the use of the Website Storage Settings panel of the Flash Player Settings Manager here; the Better Privacy add-on is an option for those who surf with Firefox.
