( CNN ) -- As Facebook continues the slow rollout of a tool to let users search out others by using common interests or other personal information , the site emphasized Thursday that minors will get special privacy protections . Graph Search capitalizes on Facebook 's massive bank of data about its users , or `` social graph , '' to seek out friends , or other users who have made their information public , using information about them . So , for example , you could seek out friends who `` like '' director Quentin Tarantino to make an invite list to see `` Django Unchained '' Friday night or remind yourself which of your friends are over 21 and live in Austin , Texas , to do some bar-hopping while you 're in town . But privacy advocates are worried . While Graph Search wo n't show you any information that you could n't see otherwise , it does pull all that data together in one place in a way that could have some creepy uses . Say , searching for the names of girls who attend a certain middle school . That 's the sort of thing Facebook aims to prevent . Details including birthday , school , hometown and current city will only be available about users under 18 to their friends and friends of friends . And friends of friends will only be able to see them if they , too , are under 18 . `` What we really wanted to do was try to identify things that could be even more sensitive for minors -- that would identify them by their age and location , '' Nicky Jackson Colaco , Facebook 's manager of Privacy & Safety , told CNN Thursday . `` Those kind of things are more sensitive and we wanted to really make sure they had an even more restrictive experience . '' Of course , she noted , the extra protections only kick in if minors are honest about the age they give to register for the site . `` This is true across Facebook . It 's really important to us that minors represent their real age , '' she said , urging parents to make sure their children are doing so . `` If they tell us they 're 25 , they 're not getting these protections and a lot of other protections we offer . '' Separate from Graph Search , Facebook already limits some content posted by minors to `` Friends of Friends '' only , even if the young user has made it public . The site 's minimum age is 13 . The tool was announced last month by CEO Mark Zuckerberg . The new search feature lets you draw connections between people , their profile information and their interests on Facebook . In theory , it 's a good recipe for finding recommendations for doctors , businesses , products , TV shows or bands . It can also be used to find people that fit a specific profile , such as `` men over 30 who live in Cleveland . '' Users will be able to seek out people who are n't their Facebook friends using the tool . But the only information they 'll see are things that a user has posted as `` public '' to the site . Graph Search currently has only been made available to a handful of early testers . But some of them have used it in ways they say raise privacy concerns . British tech blogger and `` gadget geek '' Tom Scott created a blog called `` Actual Facebook Graph Searches . '' While some are humorous ( people who like both the anti-gay marriage Focus on the Family and openly gay actor Neil Patrick Harris ) others suggested something more troubling . For example , he shows a search for family members of people of Chinese descent who like Falun Gong , the religious movement banned in China . Or one for Islamic men living in Tehran , Iran , who are romantically interested in other men . ( Homosexuality is illegal there ) . The searches could then be refined to see photos of the users , their friends and places they 've worked . Facebook has emphasized privacy settings to keep such information from being publicly visible and said they 're continuing to fine-tune the tool as it rolls out . In December , Facebook overhauled it 's privacy controls , adding a handful of features while simplifying and clarifying how existing features work .
