Photo safeguards confidential information

23.10.2008
These days you can take a photograph with almost every mobile phone. However, using this sort of photo to protect confidential data and send it safely is something new. Ileana Buhan, a PhD student at the University of Twente, has been researching this new way of employing biometrics. She receives her doctorate from the Faculty of Electrical Engineering, Mathematics and Computer Science on 23 October.

In order to recognize someone from their physical characteristics, you need to make a biometric record of them, consisting of a fingerprint, photograph or iris scan. This is a much more reliable check than the simple four-digit password on most mobile phones. As the majority of mobile phones and PDAs are already fitted with a camera, face recognition using a photo is an obvious choice. Buhan's research has made various contributions to this new biometric application.

Buhan developed a mathematical method for storing biometric data securely. Using this data, a mobile device is able to recognize people under different circumstances, so even if the user has altered his hair drastically, the system can still recognize him.

Two photos give password
Buhan wondered if you could also use such photographs or other biometric data for accomplishing secure information exchange between two mobile devices. If Bluetooth is used to do this – again with a simple four-digit password – security and privacy cannot be guaranteed. Instead, Buhan suggested constructing a password from two photos so that it would be almost impossible to decode it. To do this, two users need to save their own photos on their PDAs. They then take photos of each other. The PDA compares the two photos and generates a security code for making a safe connection. The users can then use this connection to exchange confidential information. The photos are stored as a template that contains the essential features for recognition. This safe template transfer is not just suitable for PDAs, but for every other biometric recognition system.
A firearm recognizes its owner
This idea of using biometrics for safe storage and transfer arose from the SecureGrip project. This is a project in which the grip of a policeman’s firearm is biometrically protected, in this case with a ‘personal grip' covered with a network of pressure sensors. These recognize the way in which the user holds the firearm. If someone else holds the weapon, it does not work. So what happens if a policeman needs to borrow a firearm from his colleague? The same as for the photos: the policemen have to hold each other's firearms for a short time, in order to create a suitable code.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

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...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

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...
