Supercookie Monster Eating Your Privacy for Lunch
You already know that every word you type on your browser is being tracked and used to profile and deliver highly-relevant advertisements to you (Big Brother Lives in Your Browser). And you know that most websites install “cookies” onto your computer in order to store relevant information about you (account numbers) that make surfing more convenient, and to gather information that allows advertisers to know more about you. You probably even know how to delete them.
But new research has shown that deleting cookies doesn’t always help. A new breed of cookies, called supercookies, can reconstruct all of your profile history even after the cookie has been deleted. MSN.com and Hulu.com just got caught using supercookies to track your surfing habits in stealth mode (you have no way of knowing that it’s happening, and you can’t do anything about it). The Wall Street Journal had this to say about supercookies and history stealing:
Hulu and MSN were installing files known as “supercookies,” which are capable of re-creating users’ profiles after people deleted regular cookies… The spread of advanced tracking techniques shows how quickly data-tracking companies are adapting their techniques… ["history stealing"] peers into people’s Web-browsing histories to see if they previously had visited any of more than 1,500 websites, including ones dealing with fertility problems, menopause and credit repair… Supercookies are stored in different places than regular cookies… | WSJ 8/18/11 | Supercookies on WSJ for non-subscribers.

The world is spying on you, and you don’t really even know it. A recent investigation by the Wall Street Journal concludes that spying on consumers in order to sell their data is one of the fastest-growing internet businesses. Here is a summary of the most striking findings:
“The Study found that the nation’s 50 top websites on average installed 64 pieces of tracking technology onto the computers of visitors, usually with no warning… the Journal found new tools that scan in real time what people are doing on a Web page, then instantly assess location, income, shopping interests and even medical conditions. These profiles of individuals, constantly refreshed, are bought and sold on stock-market like exchanges.”
The tracking software records and analyzes your browsing patterns. It knows if you’re surfing porn sites, researching bipolar disorder or watching teen movie trailers. With startling accuracy, it interpret’s these patterns and sells the information to websites, sometimes within seconds, that want access to your wallet. What’s the big deal, you ask? Why not let them market to us in highly targeted ways?
