This morning鈥檚 media event was a new tool to find content and data on Facebook that could wind up making information about you far easier your friends or just about anyone else to find. Graph Search allows you to search Facebook for specific people, places, or content 鈥� for example, 鈥渇riend of friends who live in New York and like sushi鈥� or 鈥渞estaurants liked by friends who also like Taco Bell鈥� 鈥� using a brand-new interface. Here鈥檚 what that means 鈥� and how you can follow Mark Zuckerberg鈥檚 suggestion to so that your private information isn鈥檛 suddenly available to others.

Facebook emphasized that and does not expose any new information about users to anyone. However, controlling your personal data means controlling not only who can see your information but how it can be found and what can be done with it. And there is no question that Graph Search actually does open up a number of new ways that your buried content can be discovered and used, including not only content you made publicly available years ago but even photos you intentionally 鈥渉id鈥� from your timeline.

Graph Search also potentially undermines the privacy protections in Facebook鈥檚 advertising model. Currently, advertisers on Facebook use a similar (but more limited) system to Graph Search to identify targets for ads 鈥� 鈥渦sers under 35 who live in Texas,鈥� for example 鈥� and then send ads to those users. One of the key pieces of that system, however, was the fact that the advertisers never actually received a list of the users who fit that profile 鈥� Facebook brokered the exchange so that the ad was properly delivered without the identity of the recipient ever being exposed to the advertiser. Graph Search could potentially eliminate that privacy-friendly step, allowing advertisers and other companies to easily identify Facebook users whose publicly-available data fits a specific profile.

To his credit, Mark Zuckerberg did recognize that Graph Search can expose information that was previously buried, and actually encouraged users to Here鈥檚 how you can do just that:

Use Facebook鈥檚 鈥淧rivacy Shortcuts鈥� menu (the lock icon in the upper right corner of the Facebook web page) to change the default privacy setting for your future posts.
Under the shortcuts, review your 鈥渁ctivity log鈥� to see what else you鈥檝e posted or been tagged in that Graph Search users might be able to find. (Remember that changing your default setting only affects future content, not past content.)
You can also go directly to the page (under the gear in the upper right), where you can do either of the above or 鈥渓imit the audience for posts you鈥檝e shared with friend of friends or Public鈥� to set all of your past content to friends only.

Postscript: our favorite part of the press conference? Mark Zuckerberg was asked about integrating Facebook鈥檚 data with more general web search, and said that he Here鈥檚 hoping that Facebook will show that same respect going forward.
