Facebook in Privacy Breach
Top-Ranked Applications Transmit Personal IDs, a Journal Investigation Finds
Facebook founder and CEO Mark Zuckerberg addressed the F8 developer conference this spring.
Many of the most popular applications, or "apps," on the social-networking site Facebook Inc. have been transmitting identifying information—in effect, providing access to people's names and, in some cases, their friends' names—to dozens of advertising and Internet tracking companies, a Wall Street Journal investigation has found.
The issue affects tens of millions of Facebook app users, including people who set their profiles to Facebook's strictest privacy settings. The practice breaks Facebook's rules, and renews questions about its ability to keep identifiable information about its users' activities secure.
Facebook says it is taking steps to "dramatically limit" the exposure of users' personal information, after a WSJ investigation showed that personal IDs were being transmitted to third parties via Facebook apps. But how hard is it to fix such a breach - and how concerned should users be about the sharing of these IDs? Julia Angwin joins Digits to discuss.
The problem has ties to the growing field of companies that build detailed databases on people in order to track them online—a practice the Journal has been examining in its What They Know series. It's unclear how long the breach was in place. On Sunday, a Facebook spokesman said it is taking steps to "dramatically limit" the exposure of users' personal information.
"A Facebook user ID may be inadvertently shared by a user's Internet browser or by an application," the spokesman said. Knowledge of an ID "does not permit access to anyone's private information on Facebook," he said, adding that the company would introduce new technology to contain the problem identified by the Journal.
"Our technical systems have always been complemented by strong policy enforcement, and we will continue to rely on both to keep people in control of their information," the Facebook official said.
"Apps" are pieces of software that let Facebook's 500 million users play games or share common interests with one another. The Journal found that all of the 10 most popular apps on Facebook were transmitting users' IDs to outside companies.
The apps, ranked by research company Inside Network Inc. (based on monthly users), include Zynga Game Network Inc.'s FarmVille, with 59 million users, and Texas HoldEm Poker and FrontierVille. Three of the top 10 apps, including FarmVille, also have been transmitting personal information about a user's friends to outside companies.

A new report in the Wall Street Journal's "What They Know" series illustrates how companies like Microsoft must balance conflicting interests: helping people surf the Web with its browser to keep their mouse clicks private, and helping advertisers who want to see those clicks. WSJ's Julia Angwin, Nick Wingfield, and Jessica Vascellaro join host Simon Constable as panelists on this special Digits live show.
