1 . Most online fraud (诈骗) involves identity theft. Passwords help. But many can be guessed. Newer phones, tablets, laptops and desktop computers often have strengthened security with fingerprint and facial recognition. But these can be imitated. That is why a new approach, behavioural biometrics (行为生物识别) is gaining ground.

It relies on the wealth of measurements made by today’s devices. These include data from sensors that reveal how people hold their phones when using them, how they carry them and even the way they walk. Touchscreens, keyboards and mice can be monitored to show the unique ways in which someone’s fingers and hands move. These features can then be used to determine whether someone attempting to make a deal is likely to be the device’s habitual user.

“Behavioural biometrics make it possible to identify an individual’s unique motion fingerprint,” says John Whaley, head of Unifyid, a firm in Silicon Valley that is involved in the field. When coupled with information about a user’s finger pressure and speed on the touchscreen, as well as a device’s regular places of use-as revealed by its GPS unit — that user’s identity can be pretty well determined.

Used wisely, behavioural biometrics could be a great benefit. In fact, Unifyid and an unnamed car company are even developing a system that unlocks the doors of a vehicle once the pace of the driver, as measured by his phone, is recognized. Used unwisely, however, the system would become yet another electronic spy on people’s privacy, permitting complete strangers to monitor your every action, from the moment you reach for your phone in the morning, to when you throw it on the floor at night.
