Pressure-Sensitive Passwords Proposed

New biometric security detects finger pressure for access. Making an impression just got easier. Scientists in the United Kingdom have announced the development of biometric devices that detect finger pressure, which could be used for biometric security on portable technology products. The devices are known as piezo-electric (or pressure electricity) and piezo-resistive sensors. They were developed by scientists Neil White and Neil Henderson at the University of Southampton in the United Kingdom with colleagues at the University of Twente in the Netherlands. The sensors detect the unique pressure stamp created by an individual user tapping out a rhythm or sequence, such as a personal information number. White and his colleagues studied the waveforms that 34 subjects generated as they tapped on a piezo-electric sensor mounted on a smart card. Full Story
