Query: RaspiReader: An Open Source Fingerprint Reader Facilitating Spoof
  Detection   We present the design and prototype of an open source, optical fingerprint
reader, called RaspiReader, using ubiquitous components. RaspiReader, a
low-cost and easy to assemble reader, provides the fingerprint research
community a seamless and simple method for gaining more control over the
sensing component of fingerprint recognition systems. In particular, we posit
that this versatile fingerprint reader will encourage researchers to explore
novel spoof detection methods that integrate both hardware and software.
RaspiReader's hardware is customized with two cameras for fingerprint
acquisition with one camera providing high contrast, frustrated total internal
reflection (FTIR) images, and the other camera outputting direct images. Using
both of these image streams, we extract complementary information which, when
fused together, results in highly discriminative features for fingerprint spoof
(presentation attack) detection. Our experimental results demonstrate a marked
improvement over previous spoof detection methods which rely only on FTIR
images provided by COTS optical readers. Finally, fingerprint matching
experiments between images acquired from the FTIR output of the RaspiReader and
images acquired from a COTS fingerprint reader verify the interoperability of
the RaspiReader with existing COTS optical readers.
