Why Should You Learn More About Privacy Sandbox?
by Arnab Dey Technology 20 April 2023
While the end of third-party cookies has been postponed, the much-dreaded changes are expected to arrive in 2024 when Google Chrome will stop supporting this solution.
That’s why it is necessary for businesses to start preparing for the cookieless future sooner rather than later and ensure a smooth transition of their marketing efforts. Thanks to the Privacy Sandbox initiative, this process can be less daunting than anticipated.
Learn the basics of Privacy Sandbox
The Privacy Sandbox is a collaborative project between Google and the World Wide Web Consortium (W3C), initiated in August 2019. Its primary objective is to establish a set of brand-new standards and tools that cater to the privacy concerns of Internet users while allowing advertisers and websites to access their information.
The origin of the Privacy Sandbox can be traced back to the gradual phasing out of third-party cookies we’ve seen recently. It prompted the need for the development of alternative ways for advertisers to engage with users.
The Privacy Sandbox project aims to find a middle ground that satisfies all interested parties and addresses the growing concern about online tracking and data accuracy. It’s worth noting that the Privacy Sandbox solutions are designed for both websites and Android environments.

The Ins and Outs of Privacy Sandbox
Privacy Sandbox is a collaborative project that brings together various companies and contributors in order to work towards addressing three main challenges in the post-cookie era.
Firstly, the project aspires to design innovative and privacy-preserving technologies that can replace cross-site tracking. Secondly, Privacy Sandbox wants to enable publishers and developers to deliver ad-supported content freely. And thirdly, the project plans to establish new internet privacy standards while working with the advertising industry.
Rather than offering a single solution, Privacy Sandbox presents a range of ideas that differ in their approach but share a common goal. The central focus of these proposals is to ensure that personalized adverts are delivered to groups of anonymous users rather than individuals, as it was up to this point.
Main Privacy Sandbox ideas
There are currently four primary proposals under the Privacy Sandbox umbrella. Attribution Reporting API is a solution that aims to preserve user privacy by replacing third-party cookies with a two-event measurement. The API records the first event on a publisher’s website, such as clicking on an ad, and the second event is a conversion on an advertiser’s website.
FLEDGE is a five-step process that begins with the browser registering interest groups. Then, while buyers provide ads and bidding functions, sellers conduct an on-device auction. The browser renders the winning ad and the seller and buyer exchange reports. With Topics API, the Chrome browser identifies the number of subjects that a user is interested in based on their browsing history.
The data is deleted after three weeks, and the system defines new topics. Finally, CHIPS is a proposal that makes cookies for each site rather than for each user. It allows widgets to identify a user’s activity on a single website, reducing the risk of data leakage.
