Google wants to replace passwords with body language.

At a Google I/O conference last week, the search engine giant said it was moving forward with Project Abacus, which aims to render passwords a relic of the old computing paradigm.

“Phones have all of these sensors in them. Why couldn’t it just know who I am?” asked Daniel Kaufman, head of Google’s research unit ATAP (Advanced Technology and Projects), during a presentation at the conference.

The project’s basic aim is to “get rid of passwords and all the annoying things” that go along with them, he said. The comments were reported by CNET this week.

Currently, secure logins — most commonly used by banks — require so-called two-factor authentication. So, for instance, in addition to a password, you must provide a unique PIN sent via a texting app or email.

Instead, Project Abacus would try to zero in on unique things about you, your behaviour, and your body. That includes factors such as typing, walking, and voice patterns combined with what apps you use and your location to verify identity.

Google calls this combination of factors a “Trust Score”. Though it’s not yet clear how exactly Google would use this, an example might be an app that requires a high level of security. A banking app might require, for instance, a higher trust score than a music app. In the case that your Trust Score is too low, then Google would revert to a password.

Other possibilities include locking down the device if Google detects that it has been picked up by a non-authorised user.

Google’s machine intelligence group (among others) is working on the project. “This June we’re going out to several very large financial institutions for initial testing and assuming this goes well, this should become available to every Android developer around the world by the end of the year,” said Mr Kaufman during his presentation.

Endpoint Technologies president Roger Kay said: “Google’s approach is like a fingerprint, taken collectively.”

“The sum of your patterns ... will yield a statistically unique signature: the way you walk, where you are, the way your finger moves, etc. Depending on how it’s implemented, these are all things ‘you are’,” he said.

But whether this technology actually makes it to your smartphone is far from certain. Google has a less-than-stellar track record with research projects coming to real-world-use fruition.

And a technology like this could potentially impact a smartphone’s battery life, among other downsides.

“One wonders (if it has) too large a footprint in memory (and is) too slow,” Mr Kay said, though he added that the idea is sound.

Consumers favour alternative methods of authentication such as fingerprint scanning, voice recognition, facial recognition and iris scanning, according to survey results released by identity management specialist Gigya this week.

Some 52 per cent of the 4000 US and UK adults surveyed said they would prefer alternatives to traditional usernames and passwords.

Biometric authentication was cited as more secure than usernames and passwords by 80 per cent of respondents. Nearly half of all millennials surveyed said they have used at least one form of biometric authentication.
