Facebook Leakage

An article in the Wall Street Journal has revealed that some Facebook Apps, including the popular Farmville, are providing Facebook usernames to marketing companies. The marketing companies can use that information to track user activities online. While users’ online activities are often tracked and mapped to an anonymous user’s PC, having access to users’ Facebook ID allows marketing companies to associate a specific person with the data collected. In an effort to avoid any further criticism, Facebook is considering the use of encryption to block third-party application providers from sharing user-sensitive information.
