Flash Cookies, a Little-Known Privacy Threat

Wiini recommends a blog posting exploring Flash cookies, a little-known threat to privacy, and how you can get control of them. 98% of browsers have Macromedia Flash Player installed, and the cookies it enables have some interesting properties. They have no expiration date; they store 100 KB of data by default, with an unlimited maximum; they can't be deleted by your browser; and they send previous visit information and history, by default, without your permission. I was amazed at some of the sites, not visited in a year or more, that still had Flash cookies on my machine. Here's the user-unfriendly GUI for deleting them, one at a time, each one requiring confirmation.
