Google buys sound authentication start-up

News by Doug Drinkwater

Google has acquired SlickLogin - an Israeli start-up which has developed technology that allows websites to verify identities by using high-frequency sound waves.

The patented technology works by playing a uniquely generated, almost silent audio through computer speakers, and this is then picked up by an app running on a nearby smartphone or tablet. This app analyses the sound and sends back a signal to confirm the identity, after which the user is able to log-in.

The technology could well be used to replace passwords, or alternatively added as an additional security layer to improve password security. Google was one of the early adopters of two-factor authentication.

SlickLogin confirmed the acquisition on its website but did not disclose any financial details on the deal.

"Today we're announcing that the SlickLogin team is joining Google, a company that shares our core beliefs that logging in should be easy instead of frustrating, and authentication should be effective without getting in the way," said the company in a statement.
