Facebook explains ad moves to try to prevent privacy freakout





Facebook, responding to worries about some of its recent advertising changes, shared some details about how it safeguards user information and said it created its new features with "privacy in mind."




Joey Tyson, Facebook privacy engineer, said yesterday in a blog post that while Facebook has designed its site to show ads that "help people discover products that are interesting to them," it also realizes that users trust the company to protect their information.




"Maintaining that trust is a top priority as we continue to grow," he said.




Tyson took pains in his blog post to explain how the new features -- such as Facebook Exchange and Custom Audiences -- gather user data and share information with advertisers. For some, that includes substituting a user's private information with so-called hashes so marketers don't actually possess a person's data.
