The fingerprint is something unique in us and that allows us to identify ourselves. That is why its implementation on mobile devices has been something very useful for the user.
Thanks to this you do not have to remember passwords or patterns, just read your fingerprint and the device recognizes you. In this way we can unlock the terminal or make payments with total comfort and simply supporting the finger.
You might think it is one of the most reliable authentication methods, since the physical presence of our finger is needed, but, what happens if our footprint is stolen??
Researchers at Japan's National Institute of Informatics have created a method that would allow fingerprints to be copied into photographs taken up to three meters away with a digital camera..
Today's digital cameras, as well as those of many mobile terminals, have enough image quality and resolution to allow you to capture the footprint perfectly. While the maximum distance seems to limit this 'kidnapping'’ Finger, any selfie or 'selfie'’ where a finger appears would be affected.
Based on these photographs, researchers obtained valid data to authenticate correctly in fingerprint-protected security systems.
Protect your fingers. Passwords can be changed, footprints are for life.
