"So if a user came to Hulu.com from an ad on Facebook, and then later, using a different browser on the same computer, visited Hulu.com from Google, and then at some point signed up for the premium service, KISSmetrics would be able to tell Hulu all about that userâ€™s path to purchase (without knowing who that person was). That tracking trail would remain in place even if a user deleted her cookies, due to code that stores the unique ID in places other than in a traditional cookie."
â€œThe stuff works even if you have all cookies blocked and private-browsing mode enabled,â€ Soltani said. â€œThe code itself is pretty damning.â€
"The researchers were reprising a study from 2009 which discovered that some of the netâ€™s biggest sites were using technology from online ad tracking firms Clearspring and Quantcast to re-create usersâ€™ cookies after users deleted them. The technique involved using a little known property of Flash to hold onto unique ID numbers. Then, if a user deleted her cookies, the companies would check in the secondary stash for the user ID, and use it to resurrect the traditional HTML cookies."

I am speaking of the life of a man who knows that the world is not given by his fathers, but borrowed from his children; who has undertaken to cherish it and do it no damage, not because he is duty-bound, but because he loves the world and loves his children… - Wendell Berry, 1971
