"We are concerned because the EC's approach to anonymisation fails to protect Europeans' privacy: our red team managed to re-identify users in less than two hours."
"The two-hour claim, in that frame, is an empirical statement, not a rhetorical one. Vassilvitskii's red team, working from a sample of search-engine query data anonymised under the Commission's proposed method, was able to re-identify individual users within two hours."
Sergei Vassilvitskii, a distinguished scientist at Google, warned the European Commission that its proposed anonymisation method for search-data sharing is vulnerable. His red team demonstrated that they could re-identify users in less than two hours using the Commission's method. The Commission's requirements include the scope of data sharing, the anonymisation method, access conditions, and eligibility of AI chatbot providers. Concerns have been raised about potential large-scale surveillance if the anonymisation methods are inadequate, emphasizing the need for effective privacy protection.
