- Don’t recklessly leave voice samples on the internet. Take control of what you post.
You can already create voice replicas based on several-second recordings. The fewer recordings left in the public domain, the less likely it is that a voice pattern will be created to be used for dishonest purposes. Conscious voice management reduces the risk of theft.
- Have limited trust in voice assistants and people whose voice sounds suspicious.
In case you are not sure whether the person on the other end of the handset is who they claim to be, hang up and contact this person again to confirm the compatibility.
- Use strong multi-factor authentication (2-3 factor authentication) when logging in.
This type of multi-factor authentication, in particular based on voice biometrics (e.g. VoiceToken), is 100% safe and effective. What it is and how it works you can read at the link.
- On personal devices (computer, laptop, smartphone) use professional voice biometric systems.
In this way, you will avoid extortion or loss of image by a potential fraudster impersonating another person for dishonest purposes.
- Use available systems for evaluating the viability (or veracity) of a voice stream source.
