I read this article:
http://www.wired.com:80/epicenter/2009/08/you-deleted-your-cookies-think-again/
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.”
Even the Whitehouse.gov showed up in the report, with researchers reporting they found a Flash cookie with the name “userId.” The site does say in its privacy policy that it uses tracking technology but it does not mention Flash or tell users how to get rid of the Flash cookie.
Wondered if any of you guys and gals know about this type of technology, and how to remove it.
