Japan Researchers Warn of Fingerprint Theft From 'Peace' Sign (phys.org)

Tulsa_Time quotes a report from Phys.Org: Could flashing the "peace" sign in photos lead to fingerprint data being stolen? Research by a team at Japan's National Institute of Informatics (NII) says so, raising alarm bells over the popular 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, reports said. The NII researchers were able to copy fingerprints based on photos taken by a digital camera three meters (nine feet) away from the subject.

      Wrong. Fingerprints are great authenticators (and not particularly good identifiers; uniqueness guarantees are very weak), but the authentication is derived from the integrity of the measurement process, not the secrecy of the fingerprint.

      That is, the security of a fingerprint-based authentication is primarily derived from the assurance you have that the fingerprint being measured is an actual body part and not some simulacrum. In the case of attended authentication stations, where a guard examines your fingers to verify that you're not wearing latex finger covers or similar the security is actually very good. In the case of a mobile phone phone sensor or similar, the security is fairly low -- though stronger than a typical phone password when shoulder-surfing opportunities are factored in.
