Google's Cookie Killing Tech Is Now On Almost Every Chrome Browser (gizmodo.com) 68

Posted by BeauHD from the significant-milestones dept.
An anonymous reader quotes a report from Gizmodo: Google's Privacy Sandbox, a controversial set of tools and settings meant to replace third-party cookies, is now on almost every single Chrome browser, according to a company blog post published Thursday. Google says Privacy Sandbox is now available to around 97% of Chrome users, and that number will reach 100% in the next few months. The news comes on the heels of the browser's 15th anniversary, which Google is celebrating by redesigning Chrome to make it look and feel more closely aligned with the design paradigm of Android and the rest of the Google suite. The final step in this process comes in 2024, when Google will disable third-party cookies in Chrome for good, marking the end of their decades-long reign of privacy-violating terror.

Back in 2019, Google said the cookie era was coming to a close. In place of third-party cookies, Privacy Sandbox will implement a long list of new tools for the ad industry. Google, after all, makes all of its money by spying on you and turning the insights into ads, so it's not about to put itself out of business. In fairness, this new system is really more private, though it's private on Google's terms. The biggest change is "Ad Topics," a.k.a. the Topics API if you're a huge nerd who's been following this stuff for years. With Topics, Chrome will keep track of all the websites you're looking at and sort you into a variety of categories. This tracking happens in your browser and the data stays on your device. Neither Google nor anyone else gets to see your browsing history or learn anything about you as an individual throughout this process. Websites and advertising companies will know there's a person interested in a certain Topic, but they won't be able to tell who you are specifically.

There's also an extremely complicated technique websites can use to tag you with subjects they want you to see ads about, called "Site Suggested Ads." Google is also rolling out a tool called "Ad Measurement," which helps companies keep track of how well their ads are working through metrics such as the time of day you saw an ad and whether you clicked on it. Google gives users some control over how these tools are implemented. With the rollout of Privacy Sandbox comes new settings listed as "Ad privacy controls," which you can adjust in Chrome's preferences. Further reading: Chrome is About To Look a Bit Different

    Really, because this feels like a new vector to fingerprint users with. Google doesn't have a great track record with any of the stuff that has overlapped with their ability to sell ads, so I don't think anyone should give them trust here. Would love to know more.

      Also: the settings are opt-out, not opt-in. When you open your updated browser, you get a popup telling you how your privacy is now fantastic, and this can be disabled. No link to just disable it though. Just a "Settings" link where you have to go into settings and disable them all individually.

        The screen that tells you about it has two options: "No thanks" and "Yes please".

        • "No thanks" takes you to the settings page, where you have to disable them all individually, or it did when I clicked it, maybe they fixed this after some feedback...

    • You aint lying. Simple challenge. Fire up up a local httpserver and point your chrome browser to your own computer. Now run lsof -i. What? A persistent connection to google owned domains like 1e100.net? Now do it with Firefox, Vivaldi, and Brave, to see the exact same thing. Watch the encrypted dataflows. See how everything you do with every browser is flowing to Google, Azure or Amazon. Ads are irrelevant, because the privacy violations are more deeply embedded.

    • Well, there is the part where the PII is all handled locally in the browser and the only thing that gets uploaded is an aggregation category. That seems like a good thing.

      • But the combination of category and the other headers that are sent are more likely to be unique. So if you already have cookie blocking extensions installed, it will decrease your privacy. They did not launch a new 'privacy feature'. They launched a new advertising feature.
        I did get a setting to immediately disable it on the popup at the beginning. Might be different in the EU than the US?

      Topics is of little use for fingerprinting. One of the reasons FLoC, its predecessor, failed was because people (including me) got involved in the development process and pointed out how it could be used for fingerprinting.

      Topics resists fingerprinting by randomising the list of topics presented to the website, and periodically rotating the list. It's also possible to send a null list, if the browser has not had time to gather topics of interest, or if the user disables the Topics API. How useful that null

      As I understand it (note that I have no non-public information) Topics is specifically designed to provably resist fingerprinting, using the ideas from differential privacy [wikipedia.org]. I understand the skepticism, which derives from decades of Google tracking (though, honestly, I think the assumptions about tracking are a lot worse than the reality -- which should be clear from the relatively low quality of ad targeting), but Topics is specifically designed to support Google's ability to sell ads, without data collect

      Actually quite the opposite. Google has an excellent track record of removing the ability for 3rd parties to fingerprint users. They hate it when the competition does what they do themselves.

      Stopping 3rd parties from fingerprinting you doesn't overlap with their ability to sell ads, it actively promotes it.

They can't just hand it over, and they don't have to anyway. The business is advertising; that doesn't require handing over your data. All it requires is using your data to target ads. The advertiser doesn't see your data; they are just told that someone in your category saw their ad.

        The goal is to get rid of 3rd party cookies, and reduce the longevity of 1st party cookies. Since websites rely on those for targeted advertising, if Google just disabled them they would be hit with anti-trust investigations over their attempt to eliminate all the competition in the ad business. Similarly, setting themselves up as the only data broker on the internet would get the interest of regulators pretty quickl

          When all browsers have killed third-party cookies, the era of massive data collection on the web will be at an end. If it doesn't come with something like Topics, which enables targeted advertising without data collection, the end of third-party cookies will also be the end of the web's economic model. Sites will either die or paywall.

      anything that gets rid of all those "Our site uses cookies..." popups is good by me.

      They're replacing third-party cookies, not cookies. Practically every website will continue to use cookies. This merely prevents a site from serving you a cookie hosted on a third-party server, so active cookies will only be those originating on the site you are actually viewing. This has been the default behavior on Firefox and Safari for quite some time.

      OTOH if the browser is doing all this internally then it doesn't sound like it's easy to block.

      That's the whole point. Google found a way to redirect demands for privacy into a data monopoly. Marketers no longer have access to nearly as much data from Google Ads/Analytics as they once had. . .but Google still does. Now all the data is housed in Google's black box. Third-party data brokers and ad services have been tripping over themselves because their targeting has been completely ineffective since Apple rolled out their privacy protections. Now they will have nothing to offer.

      What Google has effectively done is say, "Everyone can now have privacy on the internet. . .except nothing is private from Google."

        I don't think you understand the changes. Google won't have access to any of your data; it'll never leave your device. Google will have control over how your device deduces topics of interest to you, but all advertisers will get to see the outputs of that process. So Google is in a sense in control... but without access to your data, and it's hard to see how they get a signficant competitive advantage, since the browser will serve the same topics to all ad networks.
