Abstract:
1. A digital telecommunications system comprising: one or more voice communications end point devices, each voice communications end point device comprising a microphone, a speaker and audio circuitry, the one or more voice communications end point devices comprising a first end point device; a voice identification and authentication system connectable to the first end point device via at least one network, the voice authentication and verification system connectable to a non-transitory storage device having at least one voice signature stored therein; the voice identification and authentication system communicating with the first end point device via a first audio call connection formed between the first end point device and the voice identification and authentication system in which audio data is transmittable between the first end point device and the voice identification and authentication system via a first channel of communication; the voice identification and authentication system initiating voice authentication by sending a request for a voice sample to the first end point device via a second connection with the first end point device in which data is transferred between the first end point device and the voice identification and authentication system via a second channel of communication; in response to the request for the voice sample, the first end point device recording a voice sample during the ongoing first audio call connection for transmitting the recorded voice sample to the voice identification and authentication system; the voice identification and authentication system receiving the recorded voice sample from the first end point device; the voice identification and authentication system comparing the received recorded voice sample with voice data received from the first end point device in the first audio call connection that is ongoing via the first channel to determine whether the recorded voice sample received from the first end point device sent via the second channel was a live recorded sample recorded during the ongoing first audio call connection and is not a voice sample previously recorded prior to the first audio call connection to verify the received recorded voice sample; the voice identification and authentication system comparing the received recorded voice sample with a stored voice signature stored in the storage device; the voice identification and authentication system determining that the received recorded voice sample authenticates the first end point device when the received recorded voice sample is verified as a live recorded sample recorded during the ongoing first audio call connection and a voice of the received recorded voice sample matches a voice of the voice signature; and the voice identification and authentication system determining that the received recorded voice sample does not authenticate the first end point device when at least one of (i) the received recorded voice sample is not verified as being a live recorded sample recorded during the ongoing first audio call connection and (ii) the voice of the received recorded voice sample does not match the voice of the voice signature.
