GDPR complaint claims Google and IAB ad category lists leak intimate data

The real-time bidding (RTB) complaint, which was lodged last fall by Dr Johnny Ryan of private browser Brave; Jim Killock, previously director of the Open Rights Group; and Michael Veale, a data and policy researcher at University College London, alleges “wide-scale and systemic breaches of the data protection regime by Google and others” in the behavioral advertising industry. The individuals filing the complaints have now submitted additional evidence showing lists of ad categories used by Google and online ad industry association, the Internet Advertising Bureau (IAB), that they say show sensitive inferences are systematically made. The original complaints argue that Internet users are unlikely to be aware such labels are being routinely stuck on them, let alone how widely their personal data is being shared with third parties participating in programatic ad auctions that rely on scale as a core function.
