Graph Search raises privacy concerns from security experts

Facebook’s new Graph Search has security experts warning people who use the social network to raise their privacy settings in order to avoid embarrassment or becoming victims of cybercriminals.

Graph Search, which Facebook introduced this month and is rolling out gradually, lets people use naturally phrased queries, such as “Mexican restaurants my friends like,” and receive personalized results. The service makes a lot more useful information available to people, and it gives Facebook a new venue for selling advertising.
