New method to track fingerprints found

SINGAPORE: A device that captures elusive fingerprints where
current methods fail has been developed at Nanyang Technological
University (NTU), researchers said on Saturday.

Using a patented optical and signal processing technique, the
device has scored a first in fingerprint technology by
reconstructing prints that were previously considered too faint,
old, overlapping or left on oily surfaces, NTU said.

The research team behind the innovation is from NTU's School
of Mechanical and Aerospace Engineering, led by Associate
Professor Seah Leong Keey.

The system reconstructs a fingerprint by measuring differing
wavelengths of light bounced off it under lenses. -- DPA
