'Peace' sign photo poses could lead to fingerprint data being stolen
Could flashing the "peace" sign in photos lead to fingerprint data being stolen?
Research by a team at Japan's National Institute of Informatics says so, raising alarm about the two-fingered pose.
Fingerprint recognition technology is becoming widely available to verify identities, such as when logging on to smartphones, tablets and laptop computers.
But the proliferation of mobile devices with high-quality cameras and social media sites where photographs can be easily posted is raising the risk of personal information being leaked.
Researchers were able to copy fingerprints based on photos taken by a digital camera 3m from the subject.
"Just by casually making a peace sign in front of a camera, fingerprints can become widely available," said researcher Isao Echizen.
