An Israeli start-up says it can take one look at a person’s face and realize character traits that are undetectable to the human eye.

Faception said it’s already signed a contract with a homeland security agency to help identify terrorists. The company said its technology also can be used to identify everything from great poker players to extroverts, pedophiles, geniuses and white collar-criminals.

“We understand the human much better than other humans understand each other,” said Faception chief executive Shai Gilboa. “Our personality is determined by our DNA and reflected in our face. It’s a kind of signal.”

Faception has built 15 different classifiers, which Gilboa said evaluate with 80 percent accuracy certain traits. The start-up is pushing forward, seeing tremendous power in a machine’s ability to analyze images.
