Knufactor is our active speaker recognition portfolio that uses specific words or phrases to verify an individual. Knufactor has two complimentary modes for authentication – AudioPass and AudioPIN. Both modes use dynamic prompting, so the authentication always varies – making replay attacks incredibly difficult.

The user enrolls by saying the words they will use to verify themselves three times. Once enrolled, the user verifies their identity by saying the words they are dynamically prompted to speak. Both AudioPass and AudioPIN have the added feature of vocabulary expansion, where three of four words are used to authenticate, and the fourth is a new addition to the user’s word “library,” reducing the possibility of a successful replay attack even more.

Use cases for Knufactor include: A second biometric factor for SSO or MDM; transaction confirmation; device access; and privileged user account access.

AudioPass

AudioPass is incredibly difficult to spoof. The words have to be said in rapid correct succession and the end user never knows what they will be prompted to say. AudioPass currently has a vocabulary in English and will be expanding the vocabulary and adding languages in the coming months.

AudioPass is simple– any device with a screen, a microphone and an internet connection can now include speech biometrics to authenticate users. Anyone who wants to be authenticated with their voice does a quick enrollment and then can authenticate by repeating the three or four words that are flashed across the screen. If the user misses a word, or says the wrong word, they won’t be authenticated.

Our user-friendly management console allows for the administrator to set policies for the initial enrollment, rolling enrollment for vocabulary expansion, and account roles. AudioPass can be enabled with as few as four words. For increased flexibility, AudioPass can be enabled using the AudioPIN enrollment so both modes can be enabled for different applications within the same enterprise.

AudioPIN

AudioPIN pairs something uniquely yours – your voice – with something you know – your PIN – to enhance security. It provides a complete multifactor solution to use voice for user authentication.

The interface to AudioPIN is a virtual PIN pad – which can be tailored for the platform being used to authenticate be it a tablet, a mobile phone, or a computer screen. Each number on the PIN pad has a word, and at times, the same word is in multiple locations on the PIN pad. To enroll in AudioPIN, a user sets a PIN that only he or she knows and repeats at least 10 words three times, which typically takes about 2 minutes. To authenticate using AudioPIN, users say the enrolled words that randomly populate the PIN pad in the order of their PIN.

AudioPIN is incredibly secure. In addition to the incredible accuracy of our voice biometrics, an attacker would have to be able to capture all the words a user might be prompted to say AND know the correct PIN. They would also need to be able to replay a potentially large set of words with a split second to play the words. And with vocabulary expansion, the enterprise can decide how many words a user can be prompted to say. AudioPIN currently has a vocabulary in English and will be expanding the vocabulary and adding languages in the coming months.

Our user-friendly management console allows for the administrator to set policies for the initial enrollment, rolling enrollment for vocabulary expansion, and account roles. AudioPIN can be enabled with only enrolling in ten words. For increased flexibility, AudioPIN’s enrollment files can also be used for AudioPass so both modes can be enabled for different applications within the same enterprise.
