Google Introduces Privacy Budget to Thwart Web Tracking and Fingerprinting
Google unveils a new web standard proposal that limits how much data sites can extract to identify users, building on its broader Privacy Sandbox initiative. The plan aims to balance user anonymity with publisher revenue needs.
Google announces a new initiative to prevent online marketers and advertisers from tracking users across the web. This proposal builds on previous plans to change how cookies work in Chrome and extends the company's "Privacy Sandbox" concept, which aims to enable personalization while protecting user privacy by making the web more private by default.
To combat browser fingerprinting, Google proposes the idea of a "privacy budget" that limits the amount of identifying information a website can extract. The browser allows enough API calls to group users into larger cohorts for advertising purposes, but it stops responding to further data requests once a site exhausts this budget to preserve individual anonymity.
Google argues that highly restrictive cookie blocking implemented by other browsers causes unintended consequences for publishers who rely on ad revenue. The company stresses its commitment to an open web and seeks to develop these new anti-fingerprinting controls as an agreed-upon open standard in collaboration with other players in the web ecosystem.
