Your facebook likes could give away the most intimate details of your life.

Proving that most people reveal far more information online than they are aware of, a team of university Cambridge and Microsoft researchers has identified that user's facebook likes can be used to construct highly accurate profiles,including sensitive personal attribution such as their ethnicity, religious and political opinions, sexual orientation, intelligence and history of drug use, in addition to age and gender.

Their research paper details a study of 58,000 volunteers in the US whose facebook profiles were scanned. The team developed a model to correlate personal attributes and facebook likes and achieved results comparable to those of a standard personality test, accuracy was 95 percent for determining ethnicity, 88 percent for determining male sexual orientation, 85 percent for political affiliation and 82 percent for religious affiliation. The model relied on drawing inferences based on pop cultures likes TV shows,music,celebrities,brands and ideologies. The information is a potential goldmine for advertisers but raises some serious questions about individual privacy online.
