Hacker was able to reproduce German Defense Secretary Ursula von der Leyen's fingerprint just by scanning a thumbshot. These photos were made public by the media.
Until now we knew that with enough care, fingerprints can be copied from objects with polished surfaces that have been touched by a person. This method is also used by police, but security researchers managed to prove that this can be done by anyone.
Fingerprints can be reproduced by images
In the conference for hackers Chaos Computer Club in Hamburg this year, the Jan Krissler, also known as the Starbug, presented how the biometric feature can be reproduced from the photos of a finger.
Ο Krissler is a security researcher at the Technical University of Berliny, and examines the weaknesses of biometric security systems.
The fingerprint that he managed to reproduce found her in a thumbs-up photograph by von der Leyen, which was taken at a press conference in October. Then use additional close-ups to fill the missing fingerprint sections.
The tool used by the researcher was VeriFinger, which incorporates technology recognitionof fingerprints. The software is designed for biometric system integrators and is based on a robust algorithm that conforms to the standard fingerprint recognition system.
Fingerprint Extractor is an application available for consumers on price of €20 if nine licenses are purchased.
This vulnerability is probably something that has to worry about device makers as more and more use the fingerprint recognition feature.
Obtaining a fingerprint through the Krissler method can bypass all biometric systems that ensure access to many different places because physical access is no longer required.
