Another ad-serving company, Specific Media, has been sued for allegedly re-creating cookies previously deleted by users. The class action complaint, filed in federal district court in California, alleges that Specific Media and its affiliates store tracking data on users’ computers using the Adobe Flash Media Player rather than storing them the traditional way – in internet browser cookies – making it difficult for computer users to delete. In addition, the complaint alleges that Flash cookies can be re-activated even after a user deletes them. reported that this is the third such class action complaint filed by the same attorney, and that this all started with a 2009 University of California at Berkeley research paper that revealed the growing use of Flash cookies and concluded that web site privacy policies rarely disclose the presence of Flash cookies and “user controls for effectuating privacy preferences are lacking.”
