在这篇文章中，我们将向您展示如何通过在Windows 10的(Windows 10)Google Chrome设置中禁用隐私沙盒(Privacy Sandbox)设置来退出Google Floc。FLoC本质上旨在为广告商提供他们需要的数据，以便为用户提供有针对性的广告，同时帮助用户保持数据的安全性。尽管这是他们决定将其出售给客户的方式，但并没有很多人对此深信不疑。
大(Big)数据公司与数据跟踪和隐私的关系非常不稳定。Facebook-Analytica争议等事件让我们质疑这些技术巨头在多大程度上持有和利用我们的私人数据。这些网站主要使用 cookie 进行跟踪，并且由于人们知道这些信息及其后果，因此其中许多网站对 cookie 及其相关性感到担忧。谷歌(Google)获得的大部分收入来自其广告业务，而这些网络 cookie 对广告业务起到了很大的帮助。因此，根据其隐私沙盒(Privacy Sandbox)计划，谷歌(Google)为其一部分用户（大约 0.5%）注册了一项新功能，称为队列联合学习(Federated Learning of Cohorts)，或FLoC。
什么是 FLoC？它是如何工作的？
如前所述，FLoC的目的与 cookie 类似，通过向广告商提供他们需要的数据，以便能够向用户提供有针对性的广告。它的作案手法(Modus Operandi)涉及监视其用户的浏览行为，并相应地为浏览器分配一个标识符。然后它将相似的浏览模式组合在一起（因此使用了“cohort”这个词）。这应该可以帮助广告商识别人群的行为模式，而无需真正了解其个体成员的身份，因为他们每个人都将被赋予匿名性。谷歌(Google)还表示，这个FLoC技术不会基于“敏感话题”创建群组，并且不会将与任何医学诊断相关的信息或从自杀念头中寻求帮助的信息整合到其系统中以创建这些群组。
虽然在纸面上看起来不错，但数据隐私的倡导者并不相信这一点。电子前沿基金会(Electronic Frontier Foundation)( EFF )对此表示担忧，并认为可以将这些匿名 ID 与个人联系起来。他们认为，这些群组将把人分成几千人的集体，并且由于用户群相对较小，实施指纹识别（通过浏览历史中的信息发现身份）可能比以前更容易。根据Web Browser Brave的首席执行官(CEO)Peter Snyder的说法，FLoC与当今世界需要的以隐私为中心的网络相比是一种倒退。
围绕这一新举措以及它在某些方面比Internet Cookie(Cookies)更糟糕的所有这些喋喋不休，您一定在想用户如何选择退出它。因此，今天我们将讨论用户如何检查他们是否在FLoC实验中，以及他们如何选择退出。

如何在Chrome中选择退出(Chrome)Google FLoC（隐私沙盒(Privacy Sandbox)）
很容易查明Google是否在您的(Google)Chrome浏览器上激活了FLoC设置。您所要做的就是访问 EEF 的FLoC跟踪网站amifloced.org，它会告诉您您的浏览历史是否在FLoC下被跟踪。如果您正在被FLoC跟踪，则有一些可供您选择的行动方案。您可以从Google Chrome浏览器手动选择退出，或者安装一个浏览器扩展程序，通过(Google Chrome)FLoC阻止行为浏览器跟踪。另一种措施可能是放弃谷歌浏览器(Google Chrome)并使用更注重用户(user)数据隐私的浏览器，例如Firefox、Brave、Vivaldi或 Microsoft Edge。
以下是您可以在Google Chrome浏览器上手动选择退出的方法：
- 单击(Click)浏览器窗口右上角的菜单（三个点）(Menu)
- 访问设置。
- 从右侧可用的选项中，选择隐私(Privacy)和安全(Security)
- 进一步点击隐私沙盒
- 从“隐私沙盒(Privacy Sandbox)”选项中，如果您看到“隐私沙盒(Privacy Sandbox)”试用已打开，则将其关闭。
- 这将确保将来也不会启用FLoC 。
如果您的Chrome(Chrome)设置中看不到隐私沙盒(Privacy Sandbox)控件，您不必担心。它正在推出。
禁用第三方浏览器 cookie 也可以完成这项工作。这是如何做到的：
- 从隐私(Privacy)和安全(Security)设置中，打开“ Cookie(Cookies)和其他站点数据”选项。
- 选择“(Select ‘)阻止第三方 cookie”并关闭选项卡。
如果您有兴趣安装上面谈到的FLoC预防性浏览器扩展，您可以下载(FLoC)DuckDuckGo 浏览器扩展。
我们希望本文能够帮助您解决您可能对 Google 的新计划FLoC的一些疑问，它对您的私人数据和您查看的广告的影响，并且您能够成功地选择离开它，如果你想的话。

How to opt out of Google FLoC (Privacy Sandbox) in Chrome
In this post, we will show уou how you can opt out of Google Floc by disabling the Privacy Sandbox setting in Google Chrome settings in Windows 10. FLoC has essentially been designed to provide advertisers with the data they require to provide users with targeted ads while helping users keep their data just a little bit securer. And while this is the way they have decided to sell it to its customers – not a lot of them have been convinced by it.
Big data companies have had a very dicey relationship with data tracking and privacy. Incidents like the Facebook-Analytica controversy have had us question the extent to which our private data is held and exploited by these technology giants. These websites have predominantly used cookies to track, and since this information and its consequences became known to people, there was the cause of concern among many of them regarding cookies and their relevance. A major chunk of the revenue that Google earns comes from its advertising front, which is heavily aided by these web cookies. As a result, under its Privacy Sandbox initiative, Google enrolled a new feature to a subset of its users (roughly 0.5 percent) called Federated Learning of Cohorts, or FLoC.
What is FLoC? How does it work?
As mentioned earlier, FLoC is meant to serve a similar purpose as cookies, by providing advertisers with the data they need to be able to provide targeted ads to users. Its Modus Operandi involves monitoring the browsing behavior of its users and accordingly assigning the browser an identifier. It then groups similar browsing patterns together (hence the word ‘cohort’). This is supposed to help advertisers identify the behavior patterns of groups of people without actually knowing the identity of its individual constituents since each one of them are going to be given anonymity. Google also said that this FLoC technology is not going to create cohorts based on ‘sensitive topics’ and will refrain from integrating information related to any medical diagnoses or searches for help from suicidal thoughts into its system to create these cohorts.
While it seems good on paper, advocates of data privacy aren’t convinced with this. The Electronic Frontier Foundation (EFF) is concerned and has opined that it is possible to link these anonymous IDs with individual people. They believe that these cohorts will have people grouped in collectives of just a couple of thousands, and with this relatively smaller pool of users, implementing fingerprinting (discovering identity via information from browsing history) can be easier than it was before. According to Peter Snyder, CEO of Web Browser Brave, FLoC is a step backward from the privacy-centric web that the world needs right now.
With all this chatter around this new initiative and how it, in some ways, is worse than Internet Cookies, you must be thinking how a user can opt out of it. So, today we will discuss how a user can check if they’re under the FLoC experiment and how they can opt out of it.

How to opt-out of Google FLoC (Privacy Sandbox) in Chrome
It is pretty easy to find out if Google has activated the FLoC setup on your Chrome browser. All you have to do is visit EEF’s FLoC tracking website, amifloced.org, which will tell you if your browsing history is being tracked under FLoC or not. If you are being tracked by FLoC, there are a few alternative courses of action in place for you. You could manually opt out of it from the Google Chrome browser or install a browser extension that blocks behavioral browser tracking via FLoC. Another measure could be to discard Google Chrome and use a browser that is better centered around user data privacy like Firefox, Brave, Vivaldi, or Microsoft Edge.
Here’s how you can manually opt-out of on Google Chrome browser:
- Click on the Menu on the top-right corner of the browser window (the three dots)
- Visit Settings.
- From the options available on the right, select Privacy and Security
- Further click on Privacy Sandbox
- From the Privacy Sandbox option, toggle the Privacy Sandbox trials off if you see it turned on.
- This will make sure that FLoC doesn’t get enabled in the future either.
You don’t have to worry if the Privacy Sandbox controls aren’t visible in your Chrome settings. It is being rolled out.
Disabling third-party browser cookies will do the job just as well. Here’s how that can be done:
- From the Privacy and Security settings, open the ‘Cookies and other site data’ option.
- Select ‘block third-party cookies’ and close the tab.
If you are interested in installing the FLoC preventive browser extension that was talked about above, you can download the DuckDuckGo browser extension.
We hope that this article was able to help you put to rest some of the queries that you may have had about Google’s new initiative, FLoC, it’s implications on your private data and the ads you view and that you were able to successfully able to opt out of it, if you wanted to.
