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.

    Fingerprints are not used for authentication, right? So it's not a problem, is it?

    Even the kids in my school get this - you do have to explain the first time but then it's obvious to them.

    Where do you write down your password? Almost nowhere (some of our kids have password in their planners and things like that, but they have no access anyway).

    Where do you leave your fingerprint? Everywhere you go, on everything you touch, including the device you're logging into, and every device you've ever logged into.

    Though we don't get high-level attacks, I feel that users need to only have this explained once to question the James Bond etc. concept of using fingerprints for doors, high security facilities, etc.

    The fact that cameras are at the point that you can photograph someone's fingerprint? That's been true for a little while. That means that Trump / May / whatever leader's fingerprints have basically been public-domain for the world's spies for many years. Hence you should be SERIOUSLY questioning use of fingerprints as anything more than convenience or casual use.

      Or, take a picture of something from 3meters away and see what you get when you load that image onto a computer and zoom in to it.

      Obviously you have to enhance after zooming. If you continue enhancing, you can zoom in to any image indefinitely.

      Incorrect... "enhancing" isn't anything like what you see in the movies. You can't enhance infinitely. You can enhance up to a point, but after that, there just isn't enough data and you start adding artifacts and inaccuracies. You might be able to get away with some inaccuracies depending on the fingerprint reader and the matching algorithm. That's why the researchers specified a limit in distance. They also don't go into the size of the photos, but the point is that now there is enough resolution provided by digital cameras (20MP+) and phones (10MP+) today to provide the necessary level of detail at 3 meters.

    Instead of making a peace sign when having your photo taken, an obvious solution is to flip the bird instead! Your fingerprints are facing away from the camera. All of the problems are solved, once and for all!

  11. The V of freedom and victory, not peace. by Anonymous Coward · · Score: 2, Informative

    The sign they are talking about is the V of Vrijheid and Victoire, after the Dutch word for Freedom and the French word for Victory. People in occupied Belgium used it during WWII. The gesture was used as a response to the Nazi salute, and was used every time the Germans lost a battle (the news was spread by the BBC). This way the people managed to scare the German soldier, and indirectly instructed them to be nice and to not commit war crimes. This sign was adopted in both the Netherlands and France and was even picked up by Churchill who made the symbol for the allies (after having done it wrong the first few times, he showed the back of his hands which was a way to insult other people in the British lower classes).
