Do Not Track Ineffective and Dangerous, Says Researcher 207

Seeteufel writes "Nadim Kobeissi, security researcher, describes the Do Not Track standard of the W3C as dangerous. 'In fact, Google's search engine, as well as Microsoft's (Bing), both ignore the Do Not Track header even though both companies helped implement this feature into their web browsers. Yahoo Search also ignored Do Not Track requests. Some websites will politely inform you, however, of the fact that your Do Not Track request has been ignored, and explain that this has been done in order to preserve their advertising revenue. But not all websites, by a long shot, do this.' The revelations come as Congress and European legislators consider to tighten privacy standards amid massive advertiser lobbying. 'Do not track' received strong support from the European Commission."

        It still works on some level though, otherwise they wouldn't bother doing it. Same reason there's still loads of spam. You don't need 50 million people to buy what you're selling. Just over the cost is fine, and anything beyond that is gravy. The market is relatively free, so it's going to tend towards equilibrium. So baring any external forces (e.g. government regulations) or some other massive change in the market, advertising isn't going to go away. At least there're things like ad block on the internet. Prior to DVRs there wasn't a good way to get around advertising on TV or the radio. Even if you left the room while it was on, it still ate into the program schedule. Even if you don't block ads on the web, they're by and large less obtrusive than what we had before.

      - HTML local DBs

      - IP address

    Anything that leaves your privacy on the "good will" of the companies is inefficient to protect my privacy.

    If I do want to protect it, I'll use tools like Ghostery and DNT+ where I can choose *myself* what info I send, and not rely on them honoring the DNT.

    I know I will be flagged "flame" but honestly the DNT looks a lot like the "evil bit" to me.

      So you're relying on the "good will" of a company that provides marketing data to the DMA? That seems kind of odd given your stated position on privacy.

      DNT was never designed to be a replacement for ad blocking, Ghostery and the like. It was to create a way of applying pressure to advertisers, via laws enforcing it if necessary, without creating an undue burden on the user.

      Instead of clicking "opt out of tracking" on every web site and every ad the user ticks one box in the browser. Self respecting companies with a reputation will hopefully honour it. It's like the telephone preference list / do not call list.

    Relying on the people who want to track you to honor your "Please don't" request is just guaranteeing disappointment.

    Now there are plenty of ways you can clamp down on the tracking and cross-site leakage, from NoScript to RefControl, but the single easiest cross-browser cross-platform way to do it is Ghostery: https://www.ghostery.com/ [ghostery.com]

    Most importantly, unlike the other methods (NoScript in particular) it only very rarely breaks a page. So it's just set up and forget.

    I'm sure it's not as effective as some other tactics, but the 'works on everything' and 'just works' is really key to just using it all the time everywhere.

    There is a trivial, 99% effective fix for this problem. In firefox, go to Edit:Preferences:Privacy and tell it to forget all cookies when you end a browser session. There is also a facility for whitelisting cookies from certain sites so that, for example, you don't have to log in to slashdot every time. Cookies from the whitelisted sites are remembered across browser sessions.

      They can still track by IP address and you're browser fingerprint. Browser fingerprinting can be defeated though current browsers don't seem to want to help make it easier to do so.

      I'm not sure what we'll do when IPv6 rolls around and every device has a unique address. Either you go back to NAT and share addresses, which is not completely effective due to fingerprinting, or you change your address every few hours or days. Either solution defeats the purpose of IPv6.

      The only real solution is to use adblock,

        AC is right. Deleting cookies at the end of each session may help a bit, but there are still plenty of ways to identify you [eff.org] especially if you include your IP address (but that's not always reliable).

        There's already a solution for that. [wikipedia.org] Use the randomly-generated address for normal things, but use your static address for servers and the like. IPv6 privacy extensions are supported on Windows, Mac, and Linux.

          How dare people chop of the trailing bits of an IPv6 address, thus rendering IPv6 privacy extensions ineffective.

          • If you do that, then the IPv6 prefix is just as effective as a NAT'd IPv4 address tracking-wise. No more, no less. But you're right, no one dares to track you by your IPv4 address these days...

          What we need is an extension that doesn't delete cookies, it alters them to randomize unique ID numbers and other valuable data. As well as cookies it would randomize the browser user agent string and referrer when sending requests to known ad servers. The "proxy-for" header is also fun to play with and might help combat IP addressed based tracking.

          Don't just block tracking, screw it up and poison the databases with fake nonsense data.

        The cookies go away when you restart your browser, not just when you shut down your computer.

  • It sounds like a serious comittee and companies got an inspiration from the Evil Bit proposal, even though that one was an april fools joke.

  • Both in terms of the idea and design. There is no level of Trust in the design of "Do Not Track". The server on the other end has no real obligation to honor the flag. The client has no real way to check if it is honoring the flag.

    Also something people miss: You can't legislate trust. How do you prove violations? Random audits on paper sound like the way to tackle conformance but again who is building that tool? Google, Microsoft, Amazon, etc? Again we have a lack of trust....

    For me, I don't care whether the site honors that header or not. If they're going to abuse tracking, they're not likely to suddenly come over all ethical and change their servers to not track. What the DNT header does is give a standard, recognized signal present in every single browser request that I do not consent to tracking. It's like the fence with the locked gates and "Private Property - No Trespassing" signs around a property: it's not going to keep trespassers out, but it's a clear and more importantly legally-recognized demarcation. If they jump over the fence onto my land and get in trouble because of being there, the court's going to look at the fact the land was clearly posted and tell them "Sorry, we don't accept your claim that you didn't know it was private property.". With the DNT header, no Web site can claim they didn't know I didn't consent to tracking. They can't claim implicit consent, because there's explicit non-consent in the very request they serviced. And this is why the advertisers are making such a play to get the DNT header dismissed and abandoned. Up to now they've taken the position of "You must consent as a condition of access, you accessed so we can assume your consent.". As long as there's no standard way of saying "I do not consent.", they can get away with that. But with a standard DNT header they can't argue that it's infeasible to check every possible way of not consenting. There's just one, and it's not ambiguous. The counter-argument of "If they don't want to allow access to those who don't consent, why did they not simply return an HTTP error when they saw the DNT header?" becomes rather more convincing.

    The secret the advertisers don't want to state up front is that they don't want to require consent to tracking. They just want to track everybody whether they consent or not. Anything that provides a clear, unambiguous message to them about consent or lack thereof is a threat to that position, because it makes it harder for them to argue a basis for their assuming consent.

    And a message to every Web-site and ad-network operator out there: if you're serious, stop whining and configure your servers to return 403 Forbidden to every request with the DNT header set. It's not that hard.

    • I'm surprised that this is a minority view. This is a legal issue. There are no technical means to utterly prevent tracking, but this provides a legal means for punishing people who do it. Anyone who says DNT is harmful is selling something, or bought something stupid from someone who is.

    • Hmm... if someone comes illegally onto my property after I clearly marked it, I may shoot him in defense. Say... does that work on that DNT too?

      Please, oh please say yes...

  • We've created a completely, utterly useless specification that every single (mainstream) browser now implements as a feature. In all, countless megabytes (gigabytes?) and countless manhours and processing-hours have been wasted, all for the sake of doing nothing.

    Of course, anyone with half a brain saw this coming.

  • My subject says it all. I don't really care about being tracked, I just really don't want to see *any* ads and will actively block obtrusive or irrelevant ads through various browser extensions and Proxomitron.
  • You mean, when all the major browsers enable DNT by default, everybody ends up just ignoring the flag, putting us back to where we started? I'm shocked.
