Facebook Connect: Your 8,000 Hidden Friends - BusinessWeek - 0 views

Karl Wabst on 21 Apr 09Facebook has gone a long way to protect the privacy of users on its own site. But what happens when users share their Facebook profiles and friend lists with other sites? Are social networks responsible for defending data its members decide to take elsewhere? Those questions have taken on added urgency following the introduction of tools by leading social networks, including Facebook and News Corp.'s (NWS) MySpace, that let users interact with their friends on partner sites. Facebook Connect, for example, lets a user instantly share a movie rating on Netflix (NFLX) with all or some of his or her pals on Facebook. Privacy advocates warn that these services pose a whole new set of concerns about how user data are collected and shared among sites on the Web. Using these open-networking tools, thousands of companies can unearth a trove of new data about a visitor-age, gender, location, interests, and even what a person looks like. "I'm wondering if people really understand when they're using Facebook Connect that other sites get access to their whole user profile and social graph," says Pam Dixon, executive director of the World Privacy Forum. Announced last July, Facebook Connect has already signed up more than 8,000 partner sites, many of which plan to use data collected on Facebook members for their own purposes. Joost, a video-viewing site that integrated with Facebook Connect in December, checks the ages of viewers entered on their Facebook profiles to give its own content partners-CBS (CBS), for example-a better idea of which Joost users are watching CBS programming. Digg.com will let users display their Facebook profile photos alongside comments they make on the social news-sharing site.
