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
