Summary

The Real-Time Bidding (RTB) system in online advertising has been identified as the largest data breach ever recorded, tracking and sharing user behavior and real-world locations 178 trillion times annually across the U.S. and Europe. This breach affects millions of users whose private information is broadcast to numerous companies without their consent. RTB auctions occur every time a webpage is loaded, exposing sensitive data to potentially thousands of companies for ad targeting. Major players like Microsoft and Google are implicated, with industry documents revealing no technical measures to control data dissemination. The Irish Council for Civil Liberties (ICCL) is currently litigating against the RTB industry and the Irish Data Protection Commission for failing to address these privacy violations. The financial scale of the RTB industry exceeds $117 billion, raising significant concerns about user privacy and data security. Key Points: • RTB system tracks user data 178 trillion times yearly, marking the largest data breach recorded. • Sensitive information, including location and personal preferences, is shared with thousands of companies. • ICCL is pursuing legal action against the RTB industry and regulators for inadequate data protection measures.
