Google Chrome tests inter-site ad tracking block | Internet

Blocking tracking cookies is gradually becoming a standard in web browsers: you find this in MozillaFirefox and the new MicrosoftEdge; now the Google Chrome is testing the same feature. The Canary version has an option called “Block third-party cookies” to avoid tracking between one site and another.

The experimental feature is available for Chrome Canary on macOS, Windows, Linux and Chrome OS. It “enables third-party cookie blocking and an improved interface for controlling cookies in incognito mode”, as described by Google.

After activating this flag and restarting the browser, just go to the settings and click on the option Block third-party cookies; it serves to “prevent third party websites from saving and reading cookie data”.

In doing so, sites like YouTube and Facebook will display a new icon in the address bar, warning that “this page has been blocked from setting cookies”. If you click on “Show cookies and other site data …”, this will open a new window.

You’ll see that on YouTube, all cookies from Google and the Google Marketing Platform (formerly DoubleClick) have been blocked. If you click “Sign in”, you will be taken to a Google website; in this case, cookies from YouTube will be barred.

Google promised during the I / O conference that Chrome would block cross-site ad tracking. For example, if you search for a cell phone, that same smartphone will not appear in advertisements on other sites.

The company also proposed to implement the Privacy Sandbox, which limits the information used to personalize ads, using techniques such as differential privacy and federated learning.

In Firefox 69, blocking third-party trackers has become standard for all users. Safari has measures to combat cross-site tracking. And the Chromium-based Microsoft Edge will have a feature called Crawl Prevention.

Google is proposing a way to increase privacy on the web, without ending personalized ads. This would be possible through Privacy Sandbox – a method that categorizes users by interest groups, but always anonymously. Will it work?
