Privacy Sandstorm: Research Portal for Privacy Sandbox Evaluation
Abstract
The Privacy Sandbox, launched in 2019, is a series of propos als from Google to reduce _cross-site and cross-app tracking while helping to keep online content and services free for all_ . Over the years, Google implemented, experimented, and deprecated some of these APIs into their own products (Chrome, Android, etc.) which raised concerns about the potential of these mechanisms to fundamentally disrupt the advertising, mobile, and web ecosystems. As a result, it is paramount for researchers to understand the consequences that these new technologies, and future ones, will have on billions of users if and when deployed. In this report, we outline our call for privacy, security, usability, and utility evaluations of these APIs, our efforts materialized through the creation and operation of **Privacy Sandstorm** ; a re search portal to systematically gather resources (overview, analyses, artifacts, etc.) about such proposals. We find that our inventory provides a better visibility and broader per spective on the research findings in that space than what Google lets show through official channels.
