A speaker at the Chaos Communication Congress, an annual meeting of hackers in Germany, demonstrated his method for faking fingerprints using only a few high-definition photographs of his target, German defence minister Ursula von der Leyen.
Jan Krissler, known in hacker circles as Starbug, used commercial software called VeriFinger and several close-range photos of von der Leyen, including one gleaned from a press release issued by her own office and another he took himself from three meters away, to reverse-engineer the fingerprint.
