Santa Clara-based IT security firm Sensory has released a video showing how its facial and voice recognition biometric app works.Known as TrulySecure, the app uses the existing camera and microphones on devices to enrol and authenticate, with varying security settings available. Higher security settings can require both face and voice, with impostors denied access to the devices' most important applications – Android OS does not allow locking of individual apps.”Consumers generally find it cumbersome to use PINs or passwords to lock their phones, and as a result these devices often go unlocked,” said Todd Mozer, CEO of Sensory in January. “Sensory's biometric authentication provides a high level of security, while still being convenient enough that people will actually use it.”In January, Sensory announced it was partnering with Nok Nok Labs to offer voice and facial based authentication solutions to Nok Nok Labs' customers based on the new specifications from the Fast Identity Online (FIDO) Alliance. Sensory said it will work closely with Nok Nok Labs to achieve FIDO Ready status based on the recently released FIDO 1.0 Specification and integration into Nok Nok Labs' S3 Authentication Suite.
