Google Chrome introduces integrated user tracking for advertisers.

Google Chrome built-in tracking and ad-curation platform, “Privacy Sandbox,” was officially launched on September 7,

as announced in a blog post by the company.

Initially released to a limited number of users, the platform is now accessible to approximately 97% of users.

Google plans to onboard the remaining 3% over the coming months.

While the introduction of the new tracking system has drawn criticism from privacy experts,

Google has defended its implementation.

The company argues that Privacy Sandbox is necessary to eliminate third-party cookies and fingerprinting techniques.

According to business analytics platform 6sense, Google’s Adsense service is utilized by over 80% of websites to generate ads on their pages.

In order to deliver targeted advertisements to users, Adsense employs cookies that are embedded in the user’s browser.

These cookies track user behavior across different websites,

collecting data that helps identify potential products of interest.

These cookies, commonly referred to as “third-party cookies,” are generated by Google rather than the visited website.

It’s worth noting that other competing ad platforms, including Microsoft Ads,

also make use of third-party cookies.

Privacy Concerns and Blocking of Third-Party Cookies: Browser Implementations and Google’s Stance

The practice of embedding third-party cookies has faced criticism from privacy advocates,

leading some users to search for ways to block them.

Several browsers, including Apple’s Safari, Mozilla’s Firefox, and Brave’s Brave browser,

have implemented default blocks on third-party cookies.

In Google Chrome, users can also choose to block these cookies through the settings menu.

In a blog post from January 2020, Google expressed its view that blocking third-party cookies by default should not be implemented until an alternative tracking system is developed.

The company argued that such blocks could have unintended consequences,

negatively impacting both users and the web ecosystem.

Google cautioned that blocking third-party cookies might result in the adoption of opaque techniques like fingerprinting,

which could actually diminish user privacy and control.

The recent announcement on September 7 reaffirmed Google’s stance.

“Without viable privacy-preserving alternatives to third-party cookies, such as the Privacy Sandbox, we risk reducing access to information for all users, and incentivizing invasive tactics such as fingerprinting.”

With the introduction of the Privacy Sandbox platform, Google aims to track user data within the browser itself,

eliminating the need for third-party cookies.

However, it is important to note that Google has not yet made plans to block third-party cookies by default,

which will occur at a later date.

Privacy Concerns and User Control: Google Chrome’s Privacy Sandbox, Brave Ads, and the Industry’s Balancing Act

The Electronic Frontier Foundation, a prominent digital privacy advocacy group, expressed concerns about an earlier version of the Privacy Sandbox.

They argued that while it aimed to improve privacy by tracking user behavior within the browser instead of relying on cookies, it could still be intrusive and potentially more invasive than third-party cookies in certain aspects.

The latest Chrome interface now provides users with control over Privacy Sandbox through three distinct settings located within the “Ad privacy” menu. This allows users to customize their preferences and opt-out if desired.

In addition to Chrome’s Privacy Sandbox, the Brave browser has introduced its own solution called “Brave Ads.”

Unlike Chrome’s default settings, Brave Ads are disabled by default.

Users have the option to voluntarily opt-in and, in return, receive Basic Attention Tokens (BAT) for viewing advertisements.

These developments highlight ongoing debates and efforts within the industry to strike a balance between privacy concerns and targeted advertising practices.
