The Federal Trade Commission ("FTC") has sent "educational" letters to more than 90 businesses, both domestic and foreign, that may be affected by upcoming changes to the regulations implementing the Children's Online Privacy Protection Act ("COPPA"). Among other changes, the FTC has recently amended COPPA regulations to cover a broader range of information than what was previously COPPA-regulated, including certain data collected through mobile applications and other online services. The FTC sent letters to businesses that fall into four different categories: (i) domestic companies that may be collecting images or sounds of children, (ii) domestic companies that may be collecting persistent identifiers from children, such as a mobile app capturing unique device identifiers, (iii) foreign companies that may be collecting images or sounds of children, and (iv) foreign companies that may be collecting persistent identifiers from children. These letters signal that the FTC may continue to take an aggressive stance on COPPA enforcement. Penalties for non-compliance with COPPA include injunctive relief and financial penalties of up to $16,000 per violation. Despite industry requests for an extension, the amended COPPA rules go into effect on July 1, 2013. See http://www.ftc.gov/opa/2013/05/coppa_education.shtm.
