Privacy advocates file complaints against data brokers and ad-tech companies over data protection issues

On the ground of the newly entered into force GDPR, Privacy International filed complaints against seven data brokers (Acxiom, Oracle), ad-tech companies (Criteo, Quantcast, Tapad), and credit referencing agencies (Equifax, Experian) with data protection authorities in France, Ireland, and the UK. As reported by the Financial Times, these complaints illustrate growing concern about a little-known ecosystem of companies that have built business models around buying and selling data online.
