Project Rearc, launched by the Interactive Advertising Bureau (IAB) Tech Lab in 2020, aims to reshape the digital advertising landscape in response to the impending deprecation of third-party cookies. This initiative seeks to balance personalization and privacy in the evolving online ecosystem.
The Genesis of Project Rearc
Addressing Industry Challenges
Project Rearc emerged as a response to the growing concerns surrounding user privacy and the limitations imposed on third-party cookies by browsers and operating systems. The initiative brings together over 800 business, policy, and technology specialists from 487 companies worldwide to collaboratively develop solutions for the digital advertising industry.
Core Objectives
Preserving Addressability
The primary goal of Project Rearc is to maintain user-level addressability while adhering to privacy regulations and building trust within the industry. This involves creating technical standards and guidelines for identifying consumers without relying on third-party cookies.
Key Components
Global Privacy Framework
Project Rearc is developing a standardized system for recording and propagating consumer privacy preferences across markets. This framework aims to simplify compliance with changing regulations for all industry participants.
Accountability Measures
Technical Solutions
The initiative includes the creation of an Accountability Platform and guidelines to ensure that organizations seeking access to identifiers and personal data adhere to strict standards of conduct.
Implementation Strategies
Levels of Addressability
Project Rearc categorizes addressability into three levels based on the ability to link publisher and advertiser audience data:
- No linking capability
- Browser or operating system-based linking
- Token-based identity resolution
Proposed Solutions
Seller Defined Audiences (SDA)
This solution addresses environments where audience linking is not possible, providing alternative targeting methods.
Privacy Enhancing Technologies (PETs)
A dedicated workstream focuses on developing standards and tools for privacy-enhancing technologies to support various addressability scenarios.
Industry Impact
Reshaping Digital Marketing
Project Rearc’s outcomes will significantly influence how data is collected, processed, and utilized for ad targeting, measurement, and optimization in the post-cookie era.
