Is mobile sensor-based authentication ready for the enterprise? Some big players think it might be.
An Arizona security company is working on an interesting approach to mobile authentication, one that leverages the exact angle a user holds the phone as a means of making replay attacks a lot more difficult. Aetna has been testing the method internally (according to the security company's CEO) and the company — Trusona — has announced about $18 million in funding, from Microsoft Ventures ($10 million) and Kleiner, Perkins, Caufield and Byers ($8 million).
The Microsoft Ventures funding is interesting because one of the more popular mobile authentication methods today is Microsoft's Authenticator app. Is Redmond covering its bases, or does it see the Trusona effort as threatening to displace Authenticator, at least in the enterprise IT world?
