German hacker Jan Krissler, aka 'Starbug,' claimed that by using a high resolution photograph and freely available commercial software, he could replicate the German defense minister’s fingerprint, implying that it would be enough to hack her biometric security.

"After this talk, politicians will presumably wear gloves when talking in public," Starbug told the Chaos Computer Club (CCC) conference.

Krissler took a photo of Defense Minister Ursula von der Leyen’s thumb from a distance of three meters, plus several other pictures of her thumb taken at different times, and used a program called Verifinger to recreate the print.
