A continuation of our post from a few days back.
The only biometric that can be used remotely is voice recognition. The biometrics of the voice can identify the speaker, with that person not even being present. This is done by levering the audio of that person voice. Whether it’s a video recording, or voice audio, it’s possible.
Even if you have background noise on the recording, the actual technology can identify a speaker. Whether it’s a speaker in a busy area, or with a lot of background noise in general, the accuracy is still very high.
