Biometrics using internal body parts: Knobbly knees in competition with fingerprints

  • PDF
Jan. 23, 2013 — Forget digital fingerprints, iris recognition and voice identification, the next big thing in biometrics could be your knobbly knees. Just as a fingerprints and other body parts are unique to us as individuals and so can be used to prove who we are, so too are our kneecaps. Computer scientist Lior Shamir of Lawrence Technological University in Southfield, Michigan, has now demonstrated how a knee scan could be used to single us out.

The approach based on MRI could be used to quickly register and identify people in a moving queue as they approach passport control at airports for instance or as they walk through the entrance to an office block or other building.

Shamir has tested the approach and...

Signal reconstruction with NIFTY in one, two and spherical dimensions (upper, middle and lower rows). In each row, the original signal is shown on the left, the noisy data in the center and the signal reconstruction from the data on the right. The same NIFTY code generated all three examples.

Unique software supports behavioural intervention programs

  • PDF
Jan. 21, 2013 — The internet offers users a cost-effective way of accessing information and advice on any health problem, 24-hours a day. A group of social scientists has taken advantage of this by developing software which enables other researchers to easily create interactive internet-based intervention programmes to support behavioural change. The software, known as LifeGuide, is being used in intervention programmes, for example to quit smoking or manage weight...
