New "tapping" sensor could help in fight against fraud


The way a person taps a number into a cash machine or mobile phone, could, according to scientists at the University of Southampton, be used as a means of identification, and prove useful in the battle against fraud.

Professor Neil White of the University of Southampton’s Department of Electronics and Computer Science has developed an inexpensive sensor, which can be integrated into objects of various shapes and sizes, including smart cards and hand-held devices such as mobile phones.

When a person taps on the object, a unique set of waveforms are produced, which can then be programmed and used for verification of the individual’s identity. The next time they go to use the mobile phone or cash machine, they will only be allowed access if their tapping matches their programmed identity.

The initial research has now been completed and Professor White and his team are looking at apply these sensors to a variety of applications in the area of secure systems.

’The concept of identifying people by how they knock or tap is not completely new,’ comments Professor White. ’In the early days of telegraphy, operators could identify each other by how they tapped out messages - but, the concept of using a sensor for identification is novel and our "tapping" sensor is an inexpensive device which can be applied to a wide range of scenarios.’

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
