Introduction to the Privacy Sandbox

Defining the Privacy Sandbox Initiative

The Privacy Sandbox initiative aims to create technologies that both protect people’s privacy online and give companies and developers tools to build thriving digital businesses.

The Dual Objectives of the Privacy-Sandbox

The Privacy-Sandbox has two core aims:

  • Phase out support for third-party cookies when new solutions are in place.
  • Reduce cross-site and cross-app tracking while helping to keep online content and services free for all.

The Evolving Role of Web Browsers

The Privacy Sandbox APIs require web browsers to take on a new role. Rather than working with limited tools and protections, the APIs allow a user’s browser to act on the user’s behalf—locally, on their device—to protect the user’s identifying information as they navigate the web. This is a shift in direction for browsers.

The Vision for a Privacy-First Web Experience

The privacy-sandbox’s vision of the future has browsers providing specific tools to satisfy specific use cases, while preserving user privacy.

How the Privacy Sandbox APIs Work

The Privacy Sandbox APIs enable web browsers to protect user privacy by locally processing and managing identifying information. This allows for a more secure and private web browsing experience.

The Shift from Third-Party Cookies to New Solutions

The Privacy-Sandbox aims to phase out the use of third-party cookies and replace them with new, privacy-focused solutions. This shift will enhance user privacy while still allowing for personalized online experiences.

Enhancing User Privacy While Browsing

With the privacy sandbox, web browsers will have the ability to provide enhanced privacy features, such as strengthened cross-site privacy boundaries and protection against covert tracking techniques.

Exploring the Privacy-Sandbox Proposals

Overview of Current Proposals and Their Status

Chrome and other ecosystem stakeholders have offered more than 30 proposals to date, covering a wide variety of use cases and requirements. These proposals go through a lifecycle of discussion, testing, and scaled adoption before becoming web standards.

Strengthening Cross-Site Privacy Boundaries

Several proposals aim to strengthen cross-site privacy boundaries, including CHIPS, Related Website Sets, Shared Storage, Storage Partitioning, Fenced Frames, Network State Partitioning, and Federated Credential Management (FedCM).

Enabling Relevant Content and Ads Without Compromising Privacy

The Privacy Sandbox proposals also include the Topics API and Protected Audience API, which enable interest-based advertising and ad selection without the use of third-party cookies or tracking user behavior across sites.

Measuring Digital Ads Effectiveness Anonymously

Proposals like Attribution Reporting and Private Aggregation API allow for the measurement of digital ads’ effectiveness while maintaining user privacy through anonymous reporting and summary reports.

Preventing Covert Tracking Techniques

The Privacy-Sandbox proposals also address the need to prevent covert tracking techniques, such as User-Agent reduction, User-Agent Client Hints, IP Protection, Bounce Tracking Mitigations, and Privacy Budget.

Combating Web Spam and Fraud

Proposals like Private State Tokens aim to combat web spam and fraud by allowing websites to convey limited information across browsing contexts without passive tracking.

Key Proposals and Their Impact on Privacy

CHIPS: Partitioned Cookies and Privacy

The CHIPS proposal allows developers to opt-in a cookie to partitioned storage, with a separate cookie jar per top-level site. This enhances privacy by isolating cookies between different sites.

Fenced Frames and Secure Content Embedding

The Fenced Frames proposal enables the secure embedding of content onto a page without sharing cross-site data. This prevents unauthorized access to user information.

Topics API: A New Approach to Interest-Based Advertising

The Topics API proposal allows for interest-based advertising without the use of third-party cookies or tracking user behavior across sites. This ensures privacy while still delivering relevant content and ads.

Attribution Reporting for Transparent Conversion Measurement

The Attribution Reporting proposal enables the correlation of ad clicks or ad views with conversions, providing ad techs with valuable insights while maintaining user privacy.

Private Aggregation API for Summary Reporting

The Private Aggregation API proposal allows for the generation of noisy summary reports with cross-site data, ensuring privacy while still providing aggregated information for analysis.

Addressing Technical Challenges and Concerns

Reducing the Risk of User Fingerprinting

Privacy-Sandbox proposals like User-Agent reduction and User-Agent Client Hints aim to limit passively shared browser data, reducing the risk of user fingerprinting and protecting user privacy.

Protecting User IP Addresses

The IP Protection proposal focuses on improving user privacy by protecting their IP address from being used for tracking purposes.

Mitigating Bounce Tracking

The Bounce Tracking Mitigations proposal aims to reduce or eliminate the ability of bounce tracking to recognize people across different contexts, enhancing user privacy.

Implementing a Privacy Budget to Limit Data Exposure

The Privacy Budget proposal suggests limiting the amount of individual user data exposed to sites, preventing covert tracking and ensuring user privacy.

Community Engagement and Industry Feedback
