• Flash cookies can compromise your privacy

    We discussed this privacy issue quite awhile ago, and I must admit, I totally forgot about it until getting the following newsletter Recent Lawsuits Challenge Use of Flash Cookies to Track Online Behavior : Privacy Law Blog

    As the article states,
    According to the complaints, Clearspring, Quantcast, and Specific Media each develop Flash cookies capable of tracking individual computer users’ online behavior and preferences. The suits allege these companies then partner with the remaining defendants or other third parties to install the Flash cookies and track consumer behavior across the Web. The plaintiffs allege that these Flash cookies remain on a user’s computer even after a user uses the “delete cookies” tool on his or her web browser and are capable of re-installing browser tracking cookies that users previously deleted, thus circumventing a user’s ability to prevent tracking of his or her online behavior. The complaints further allege this is done without the user’s knowledge or consent and is contrary to the defendants’ web site terms of use and privacy policies.
    We also discussed how to delete these flash cookies, here is the fix:

    Adobe - Flash Player : Settings Manager - Website Storage Settings panel

    Note: The page that comes up in the above link are the actual settings on your PC and you can reset your preferences. If, as I have done, you wish privacy, go through each tab and where possible, set the memory to None and check the Never ask again box and click the Delete all sites button.

    Also Note: Ccleaner and other cleaners do not clear these cookies from your PC.

      This is a great tip - thank you! I cleared my cookies a few months ago, and I was surprised to see how many sites had stored Flash cookies since then. They're gone now!

      For Firefox users, this looks to be an excellent plug-in to block Flash cookies:

      Great tip but I note that some cleaners, specifically CCleaner, does indeed clear flash cookies too. See: Piriform - Cleaning Flash cookies. And as noted in that link, you can change how Flash stores cookies by changing the defaults.
