A wave of hand could be your new password

London: Forgot your password again? No problem, just wave your hand!

Scientists are developing a new technology which can verify a person's identity with a wave of the hand.

A biometric sensor in a laptop or tablet computer scans the unique pattern of veins in a person's palm to verify their identity, the Telegraph reported.

The technology, developed by Intel, could do away with the multiple passwords most people use for websites.

"The problem with passwords - we use too many of them, their rules are complex, and they differ for different websites. There is a way out of it, and biometrics is an

option," Sridhar Iyengar, director of research at Intel Labs said.

He was speaking at the Intel Developer Forum in San Francisco last week.

The technology would require new biometric sensors to be built into computers. An accelerometer could be used to monitor when someone put the gadget down and automatically

lock it to prevent unauthorised access.

Iyengar added that the palm scanning technology worked much better than the finger-print scanners used on some laptops today.
