VivaGuard confirms it's really the enrolled candidate — and that they're genuinely answering, not reading a pre-written answer or being fed lines off-camera. Everything runs on your own infrastructure; no audio ever leaves your server.
Webcams and honor codes don't catch fraud that happens through the microphone — by someone who isn't the candidate, or who isn't really answering.
A stand-in sits the exam or interview in place of the real candidate.
The candidate reads a pre-written or ChatGPT answer aloud instead of thinking it through.
A helper off-camera feeds lines that the candidate simply repeats.
Video proctoring watches the screen and the room — not who is actually speaking, or how.
Is this really the enrolled person — and are they genuinely answering?
The candidate reads a random sentence aloud within a short, timed window — a liveness step that captures a genuine, live reference voice.
Any later recording is matched against the enrolled voiceprint — same person or not, with a clear accept/reject and a similarity score.
Scores how natural the speech is — disfluencies, pauses, pacing — to tell genuine thinking-aloud from a read or fed answer.
VivaGuard reasons about identity and naturalness — so it catches the fraud whether or not any tooling is involved.
