Motorola has announced it is looking at alternatives to traditional passwords in a bid to make logging into online sites, or accessing mobile phones, more secure. Among the ideas discussed at the D11 conference in California on Wednesday were electronic tattoos and authentication pills that people swallow.
The tattoos, developed by Massachusetts-based engineering firm MC10, contain flexible electronic circuits that are attached to the wearer’s skin using a rubber stamp. MC10 originally designed the tattoos, called Biostamps, to help medical teams measure the health of their patients either remotely, or without the need for large expensive machinery.
Motorola claims that the circuits, which also contain antennae and built-in sensors, could be adapted to work with mobile phones and tablets. The mobile devices could then be used to confirm the owner’s identity and log them in to accounts automatically.
This would prevent thieves and other people from being able to access a phone, or individual apps on the device, if it is stolen or lost.
Another idea presented during the keynote talk at the Wall Street Journal conference with head of Motorola Dennis Woodside and senior vice president for advanced technology and products, Regina Dugan, was a swallowable pill.
The Proteus Digital Health pill has already been approved by the U.S. Food and Drug Adminstration and was given European regulatory approval in 2010. It contains a computer chip that can be powered like a battery using the acid in the wearer’s stomach.
Once swallowed the ‘vitamin authentication pill’ creates an 18-bit ECG-like signal inside the wearer’s body that can be picked up by mobile devices and authentication hardware outside. This could be used verify the wearer is the correct owner of the device or account.
Dugan continued that the pill could be taken every day for 30 days, if necessary, without any problems. Woodside added Motorola would not be shipping these ‘right away’ but they have ‘tested it authenticating a phone, and it works.’
He continued: ‘Having the boldness to think differently about problems that everybody has every day is really important for Motorola now.’ Dugan, who used to be head of the US Pentagon’s Defence Advanced Research Projects Agency, explained that each signal emitted by the pill could be unique to each user.
Both these ideas move away from traditional passwords and towards technology that turns the user into a physical authentication token. Explaining the reasons behind the plans, Dugan said: ‘Authentication is irritating. In fact its so irritating only about half the people do it.
‘Despite the fact there is a lot of information about you on your smartphone, which makes you far more prone to identity theft. ‘After 40 years of advances in computation, we’re still authenticating the same way we did years ago – passwords.
