Google Says It May Have Found a Privacy-Friendly Substitute To Cookies (axios.com) 158

Google says its new machine learning algorithms could replace cookie-based ad targeting without invading your privacy. Axios reports: Google has been testing a new API (a software interface) called Federated Learning of Cohorts (FLoC) that acts as an effective replacement signal for third-party cookies. The API exists as a browser extension within Google Chrome. The company said Monday that tests of FLoC to reach audiences show that advertisers can expect to see at least 95% of the conversions per dollar spent on ads when compared to cookie-based advertising. FLoC uses machine learning algorithms to analyze user data and then create a group of thousands of people based off of the sites that an individual visits. The data gathered locally from the browser is never shared. Instead, the data from the much wider cohort of thousands of people is shared, and that is then used to target ads.

It's a big deal that Google says it's close to coming up with a technology that will replace cookies, because one of the toughest parts of phasing cookies out of internet ad-targeting is that there hasn't been a great solution for what to replace them with. [...] Google has other proposals to replace cookies in the works, so it's not guaranteed that FLoC will be the answer, but the company said it's highly encouraged by what it has seen so far.

      To present ads that they think are relevant but nobody cares about.

      If I search for washing machines and vendors then I have already passed the threshold for when a washing machine ad is relevant. If it was 15 years since I bought a washing machine and I still live at the same address, then maybe it's time for the ads.

      But ad providers are braindead that way and continues to serve useless ads after the purchase.

      Even worse with animated ads or even with sound - they tell me that I shouldn't buy that because they waste money on excessive marketing.

        Actually, when you're searching for a washing machine, ads that were informative would be useful. Ads that just gibber at you with enthusiasm are not. Those *might* be advantageous to washing machine vending companies prior to your decision to buy, but wouldn't be useful to you.

        OTOH, "pepsi"'s (to quote a usage from Alfred Bester) aren't really useful to anyone. I still remember the jingle that inspired that usage, and it hasn't caused me to either buy, like, or recommend Pepsi Cola in about 60 years.

        Why would advertising help me choose a new washing machine? I will look at consumer magazines for an opinion (understanding it might be biased). I will look at feature sets, prices, delivery and installation time frames. I will look at the lowest ranked reviews for the types of problems I might encounter. In all that, ads are a time wasting annoyance that instead of helping with the decision making will actually get in my way. Ads are just an annoying negative in life which I wish I could eliminate.

      This one belongs in the trash heap. Here's the Github link [github.com]. They're making a new Javascript API that specifically supports advertising. It will tell the web host what "cohort" you are in based on your interests. Here's a quote:

      "The browser uses machine learning algorithms to develop a cohort based on the sites that an individual visits. The algorithms might be based on the URLs of the visited sites, on the content of those pages, or other factors. The central idea is that these input features to the algorithm, including the web history, are kept local on the browser and are not uploaded elsewhere — the browser only exposes the generated cohort."

        They're making it a Javascript API in order to make it more difficult to for users to disable while simultaneously making it potentially more "critical" for web apps. Eventually it will be moved from an extension into Chrome proper, thus making it a properly insidious Trojan Horse that can't be thwarted by simply filtering HTTP headers.

        It's not too hard to block the other means they use. I recommend:

        uBlock Origin for general ad blocking and privacy blocking, make sure you add EasyPrivacy and uBlock's Privacy filters. I think the latter is enabled by default.

        Cookie AutoDelete will remove cookies set by sites after you navigate away from them for a configurable number of seconds. It's a bit noisy by default so turn off the pop-up telling you how many cookies it deleted. It also clears out other site data and cache related to each site.

        Decentraleyes caches popular Javascript frameworks locally so that the servers which normally host them never get pinged when they load.

        Privacy Badger adds an additional layer of privacy blocking using machine learning.

        Privacy Possom blocks a few other tricks, like referer headers and canvas fingerprinting.

        Note that the EFF link you posted isn't entirely reliable. Like most of these checkers it flags up things like unique canvas fingerprints, even though they are unique because Privacy Possom is scrambling them and they change every time you reload the page.

    Advertising is ruinous to the internet and society at large.

    Advertising dollars are what has made websites race towards the lowest common denominator. Advertising has allowed "blogs" and other shitty "news" sites to succeed while true journalism dies a slow painful death.

    Your privacy is a thing to be bought and sold for advertising money. A core essence of yourself, used as a currency for what? Funny pictures of celebrities? Easy access to conspiracy theories? You don't even get to control this currency. You are a commodity, like pigs. Like chattel. You have no value to advertisers except as a number in their web portals.

    It's disgusting. I will always block any advertising if I can, and so should everyone else - I say this as someone who used to work in an advertising company.

      There are already plenty of Internet based services that work on this model: Netflix, Hulu, Spotify, etc.

      Netflix is the only one on your list.... that doesnt do any advertising to its users (and thats generously dismissing the pre-roll advertisements for other netflix content.)

      Whatever subscription tier you have with Hulu, one of the following is true (A) Its always had advertisements, (B) It originally did not have advertisements but the jokes on you because now it does, or (C) Your tier will soon also have advertisements like the litany of previous tie

    ...google really is becoming surveillance central.

    • ...google really is becoming surveillance central.

      Becoming?
      Anyway, yeah they'll have all your cookies, all your DNS data, all your location data, all your emails, everything you text to your friends.
      What's the problem?

    A cookie is simply a key/value data pair set by a web site. It's nothing more than temporary storage. If a 3rd party script is able to set or read data that it shouldn't be able to access, the "cookie" is not the problem -- the browser security policy is. If cookies were handled correctly, advertising analytics wouldn't work at all.

    This is just a new magic black box that adds more complications to make up for the fact browsers are already totally shit at security and privacy. Well, of course this will solve the problem!

  • ... that Google's business rests on selling advertising. Targeted ads make more money than generic ads which make more money than blocked ads, ergo they want to nudge people to see targeted ads. But why the hell would an individual want FLoC when a person can just install an ad blocker and be rid of ads and cookies completely? Even if FLoC were there, it would only be a failsafe against the blocker not doing its job. Same goes for the do not track flag.

    And if this FLoC thing is on the client side, doesn't

  • tldr. However it would appear that this is taking social network manipulation to the next degree beyond Cambridge Analytica. They inverted the social graph. Without even knowing the graph, your computer will spy on you to figure out there is a graph node that includes you and tell Google which node it is.

    What sounds like "oh we anonymized you" is really, "oh, we now can identify and target any minority and sub-sub-sub minority group of individuals, AND we know who you are and can sell that information to unidentified people at any degree of anonymity we desire."

    - It is one supercookie factory to rule them all, and it could to a certain degree capture your psychological state with some accuracy, even identify traits that won't change over time. Worried about medical issue X? Looking for a house in a given area? What is your dating site profile? Your browser knows all that shit.
    - Your own computer will be coopted into driving a creepy distributed stalking program which cannot be easily thwarted without breaking the modern web
    - Cookies and cross-site coordinated supercookies will still be a thing and can now identify you in a cohort.
    - Ethical AI is not an interest of cohort calculation. To turn the child porn scarecrow back on them, there will definitely be the cohort of "underage, uneducated, innocent children who like playgrounds" and every other nasty cohort you could imagine, virtually embedded in the machine learning algorithm. Parents viewing the same URL will not see the same ads or perhaps social media posts.
    - Who is allowed to see the list of cohorts that have been generated, the keys that describe it, and whether or not such cohorts should even be allowed on an ethical basis?
    - If weaponized it would make it child's play to target and radicalize cohorts with slanted news and devil's advocate posts that nobody else can see but the cohort. Think domestic terrorists, the people who pay for them now, and foreign state actors who are constantly looking for sweet targets to exploit.

      FYI Issue #36: General Concerns about FLoC-powered abuse
      https://github.com/WICG/floc/i... [github.com]
      FLoC just seems like it will turbocharge filter bubbles. MAGA extremists will see only MAGA ads and MAGA news, with white supremacists recommended by the algorithm. No need to even notice you are living alongside people of race, gender, etc. that you find objectionable. It doesn't sound healthy to me.

  • Then it has nothing to do with privacy. It has everything to do with Google and only Google getting your data
  • We have found a new way to track you and you can't block it this time
