An anonymous reader writes: The U.S. Federal Trade Commission today updated the privacy standards that protect children's privacy online. The new rules say companies must gain parental consent before collecting a kid's geolocation data, photos, and videos. It also broadened existing language to include third parties and companies that collect data on users across multiple websites. 'While the new rule strengthens such safeguards, it could also disrupt online advertising. Web sites and online advertising networks often use persistent identification systems — like a customer code number in a cookie in a person’s browser — to collect information about a user’s online activities and tailor ads for that person. But the new rule expands the definition of personal information to include persistent IDs — such as a customer code number, the unique serial number on a mobile phone, or the I.P. address of a browser — if they are used to show a child behavior-based ads.'
