With the wave of a hand, Intel wants to do away with passwords

Passwords for online banking, social networks and email could be replaced with the wave of a hand if prototype technology developed by Intel makes it to tablets and laptops.

Aiming to do away with the need to remember passwords for growing numbers of online services, Intel researchers have put together a tablet with new software and a biometric sensor that recognizes the unique patterns of veins on a person's palm.

Intel hopes that gesture technology will catch on

Iyengar demonstrated the technology, quickly waving his hand in front of a tablet but not touching it. Once the tablet recognizes a user, it can securely communicate that person's identity to banks, social networks and other services where the person has accounts, he said.

Making laptops, tablets and smartphones responsible for identifying users would take that requirement away from individual websites and do away with the need to individually enter passwords into each of them, Iyengar said.

"We plan to work with service providers to take full advantage of this," he said.

A device using the technology would use built-in accelerometers to detect when a user puts it down, and would then log its owner off to keep unauthorized people from getting in.

The palm-identification technology was one of several demonstrations during a keynote address by Intel Chief Technology Officer Justin Rattner at the forum. Rattner runs Intel Labs, which focuses on identifying and solving future technology problems.

Rattner also showed prototype technology to improve cell-phone base stations and to efficiently and wirelessly connect devices such as printers, tablets and monitors throughout the home.

He debuted a prototype microchip with wifi technology made with digital circuitry instead of analog, a development that has the potential to lead to major improvements in performance and efficiency.

The palm-reading technology, still under development, requires new software and biometric sensors built into consumer devices, but does not require the development of any new kinds of chips, Rattner said.

The technology works much better than the finger-print scanners found on some laptops today, he said.
