Oracle is an important part of the tracking and data industry. It has claimed to have amassed detailed dossiers on 5 billion people, and generates $42.4 billion in annual revenue. Oracle’s dossiers about people include names, home addresses, emails, purchases online and in the real world, physical movements in the real world, income, interests and political views, and a detailed account of online activity: for example, one Oracle database included a record of a German man who used a prepaid debit card to place a €10 bet on an esports betting site. Oracle also coordinates a global trade in dossiers about people through the Oracle Data Marketplace. Dr Ryan, Michael Katz-Lacabe and Dr Jennifer Golbeck, are acting on behalf of worldwide Internet users with a class action who have been subject to Oracle’s privacy violations. They are represented by Lieff Cabraser, which has run significant privacy cases against Big Tech.
