Frequently asked Questions
Voice can be equally reliable and accurate as fingerprints, however, it is the only biometric that can be utilised remotely.
In the process of recording a voice, unique features of the voice are extracted and stored in a non-reversible format. The process is one-way; therefore it is impossible to re-create the human voice in the unlikely event that the data is illegally accessed.
There are numerous features in place to prevent this:
- The ‘’replay attack’’ feature detects recordings if my voice has been recorded
- The prompting of random numbers in certain circumstances guards against recordings
- SMS notifications can be implemented which can alert you in the event that anyone successfully or successfully verifies against your ID number
- If an imposter were to verify against your account, the new password is sent to your cell phone and not to theirs
Each person’s voice is unique and the latest technology is able to differentiate subtle differences or identify recordings. In addition, various techniques are used to thwart any imposter attempts e.g. SMS notifications, random digit prompting.
In the majority of cases, the biological & behavioural characteristics of twins are subtly different even though they appear and sound the same to the human eye and ear. The latest technology and techniques are able to detect these differences.
