By linking biometrics with cryptographic authentication, the VIPBOB IST project has developed a new and more secure method of verifying a persons unique identification number using an old-fashioned, but proven method - the fingerprint.
Biometrics refers to the measurement of certain properties of the human body, such as the ridges on the fingertip, the structure of this iris or the pattern of speech. Many of these properties are truly random - they are different even for genetically identical twins. As a result, biometrics is the only authentication method that can verify the identity of a person.
Conventional biometrics compares a biometric trait with a stored sample, or template. VIPBOBs virtual PIN (Personal Identification Number) maps a users biometric trait to a unique number, thus avoiding the need to store the template. Because the trait is never stored, it can never be attacked. In addition, because the virtual PIN is calculated using biometrics, it may be chosen freely and changed as often as desired.

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
