'Do Not Track,' the Privacy Tool Used By Millions of People, Doesn't Do Anything (gizmodo.com) 228

Posted by BeauHD from the rendered-useless dept.
An anonymous reader quotes a report from Gizmodo: When you go into the privacy settings on your browser, there's a little option there to turn on the "Do Not Track" function, which will send an invisible request on your behalf to all the websites you visit telling them not to track you. A reasonable person might think that enabling it will stop a porn site from keeping track of what she watches, or keep Facebook from collecting the addresses of all the places she visits on the internet, or prevent third-party trackers she's never heard of from following her from site to site. According to a recent survey by Forrester Research, a quarter of American adults use "Do Not Track" to protect their privacy. (Our own stats at Gizmodo Media Group show that 9% of visitors have it turned on.) We've got bad news for those millions of privacy-minded people, though: "Do Not Track" is like spray-on sunscreen, a product that makes you feel safe while doing little to actually protect you.

Yahoo and Twitter initially said they would respect it, only to later abandon it. The most popular sites on the internet, from Google and Facebook to Pornhub and xHamster, never honored it in the first place. Facebook says that while it doesn't respect DNT, it does "provide multiple ways for people to control how we use their data for advertising." (That is of course only true so far as it goes, as there's some data about themselves users can't access.) From the department of irony, Google's Chrome browser offers users the ability to turn off tracking, but Google itself doesn't honor the request, a fact Google added to its support page some time in the last year. [...] "It is, in many respects, a failed experiment," said Jonathan Mayer, an assistant computer science professor at Princeton University. "There's a question of whether it's time to declare failure, move on, and withdraw the feature from web browsers." That's a big deal coming from Mayer: He spent four years of his life helping to bring Do Not Track into existence in the first place. Only a handful of sites actually respect the request -- the most prominent of which are Pinterest and Medium (Pinterest won't use offsite data to target ads to a visitor who's elected not to be tracked, while Medium won't send their data to third parties.)

    The major advertisers had agreed to follow the standard. Then Microsoft quickly killed any chance of that happening by violating the standard in their browser. The agreement was that users could actively choose send DNT, selecting privacy over customization.

    Microsoft made it the *default* setting, so a DNT header was sent for everyone, though most people have never heard of it. There is no chance that sites would a) degrade their site and b) lose money, by default, for every Windows user. Once Microsoft did that, the only reasonable thing for sites to do was ignore it.

      You say Microsoft broke DNT because they actually used the header, so poor tracking networks had no choice but ignore it. You don't seem to realize that your complaint is a real life example of a catch 22: ad slingers promise they'll respect the DNT header only as long as users promise not to use it.

      The reality behind this absurd design is more interesting: the alleged "standard" had never been anything more than a publicity stunt orchestrated by Google and their (at that time) lapdog Mozilla. The reason why they did that was to block a competing DNT mechanism [theregister.co.uk], proposed by Microsoft as a W3C standard. Microsoft's design stopped your browser from connecting to a tracker site completely. It didn't rely on the tracker's good will and honesty; it was a pro-consumer, not pro-ad industry solution.

      Google realized the danger, and proposed a different mechanism (the current "standard"). Via their membership in the Digital Advertising Alliance [digitaladv...liance.org] and other ad industry groups (participants in the W3C's standardization commitee), they forced it [theregister.co.uk] through, with great fanfare, thus blocking the consumer-friendly alternative.

      The ridiculousness of the design was obvious [theregister.co.uk] at the time. Just a few things: it's impossible to enforce your settings against a non-cooperating site. It's impossible to even confirm whether your request is being honored. There's no mechanism for a site to notify you in advance that it won't respect the DNT header. Add the fact that it's opt-out (leaving the less-technical majority of users unprotected by default), and it's pretty clear who the "standard" was for - hint: it was not for consumers.

      If you want to blame somebody, you should pick Google and Mozilla. All Microsoft did is call the ad industry's bluff and expose Google's DNT for the lie it always was.

    A signal sent from the client that relies on the server side to honor some sort of contract is pointless. Even if there had been industry consensus on "what to do" with DNT, the situation would be more complex than that even in a world full of good actors. For example, GDPR would set limits on how to respond to DNT that differ from the limits set by US legislation. So from the user perspective, the exact effect of DNT would be opaque, it would be basically "turn off as much tracking as is required by the country that hosts the site, or maybe the country the site thinks you're calling from, or maybe the country the site thinks governs your particular account, if you're signed in.

    The inherent lack of clarity is bad enough, but it pales in comparison to the real problem, which is that are very few good actors on the other end of the wire, and an end user has no way to scrutinize them. By the time it is divulged that SiteX is illegally ignoring DNT and storing information outside whatever the local law permits, it's too late - the information is already sold to a thousand different data brokers and it is as undeletable as a nude selfie posted publicly to Facebook.

    The only meaningful solution is to build the protections into the client side, so that the client is prevented from sending data that can be gathered by the server end. The server cannot, and can never be, trusted by the end-user. It's disappointing that the options we have in browsers (even with extensions) are still relatively coarse. For example, we need the ability to block all active scripting (including that embedded in a page, not just by blocking specific URLs to malware Javascript sources) except for a small whitelist of items critical to the function of the site. We need a way of blocking particular APIs from being accessed by active web content (there is NO reason why a website needs to know my battery level on a mobile device. If there was a reason, it would be a very limited use case that I would only enable for that one particular site. Same principle applies to a lot of the data that's used to fingerprint browsers).

    For a long time I thought DNT was a browser-level control. Meaning when you turn it on, the browser won't send tracked info to the site. When I realized DNT simply declares that you don't wanna be tracked and it's still up to the site owners to honor your wishes... I thought I was a damn big waste of effort to create a feature that in fact misled millions of people.

    Expecting Facebook and Google to honor your wish not to be tracked? Are you out of your phucking mind? They make money by tracking. If they are forced by the government not to track, they may as well fire all their employees and shutdown their businesses.

  • 'Do Not Track,' the Privacy Tool Used By Millions of People, Doesn't Do Anything

    Who was ever foolish enough to think that it would? It's 100% voluntary with no teeth and no enforcement power whatsoever.

    It was instantly seen as a scrumptious list of people who didn't want to be tracked, and therefore of immense value to spammers, marketers, government agencies, etc etc etc.

    It's like a "Do Not Mug" list, where you publish your name and the amount of cash you have in your pocket, along with your home address.
