News release: “Representatives Joe Barton (R-Texas) and Edward J. Markey (D-Mass.), Co-Chairmen of the House Bi-Partisan Privacy Caucus, sent a letter to the Federal Trade Commission (FTC) asking the agency to investigate so-called “supercookies”, files that can be installed on computers without a user’s knowledge. Supercookies allow websites to collect detailed personal data about users, including websites previously visited. Even when consumers choose to delete regular cookies from their computers, supercookies persist. According to a report last month in The Wall Street Journal (“Latest in Web Tracking: Stealthy ‘Supercookies’, August 18, 2011), it was discovered that companies have been installing supercookies on users’ computers without their knowledge. Even technical experts at the websites in the report stated they had no knowledge that the secret files were being installed.”
