Trivia on CyberCrime
A
gummy bear hack is an attempt to
fool a biometric fingerprint
scanner by using a gelatin-based candy to
hold a fingerprint.
Low-end
optical fingerprint scanners can often be fooled with a simple image of a
fingerprint, while more sophisticated devices check for characteristics such as
electrical current and blood flow. As it turns out, however, the capacitance of
gelatin is similar to that of a human finger. Furthermore, if a gelatin-based
fingerprint is attached to a living finger, the method could fool those finger
scanners as well because the device would detect those characteristics through
the clear gelatin.
The
idea behind the gummy bear hack originated with 2002 research led by Japanese
cryptographer Tsutomu Matsumoto. Matsumoto and his team used clear gelatin to
make artificial fingers that they then used to fool fingerprint scanners. The
gelatin-based finger was successful in fooling all 11 devices tested. Reporting
on the experiment in the CryptoGram, security expert Bruce Schneier commented
that gelatin is “the same substance gummi bears are made of.”
