The European expert group on data protection and privacy issued a guidance to Social Network Service providers on measures needed to ensure compliance with EU law. The key concern of the group is the dissemination and use of information available on such networks for secondary, unintended purposes. The opinion recommended robust security and privacy-friendly default settings. Topics included processing of sensitive data and images, advertising and direct marketing, and data retention. In January, EPIC suggested regulation of Social Network Service partners, including advertisers and application developers. See EPIC's Page on Social Networking Privacy.
