Biometric & Audio AI Proctoring Hardening Techniques

Why this matters now

As deepfake and stream-injection tooling becomes accessible, a setup relying on static facial checks loses its evidential value. If your institution is considering proctoring, these are the three points to get written into the contract.

Active liveness detection

The system prompts the candidate for random, unpredictable movements — a head turn, a timed blink pattern — that a pre-recorded video cannot satisfy. Ask the vendor how often these prompts fire and what false-positive rate they measured, not merely whether the feature exists.

Multi-sensor correlation

Cross-checking camera, microphone and motion-sensor timestamps exposes the inconsistencies typical of a stream injected into the webcam driver. Specialist vendors know the technique; insist on knowing which variant is actually implemented and on which devices it was validated.

What Educati does, and does not, do

Educati offers no proctoring module: no video analysis, no liveness prompts, no sensor correlation, no biometric collection. Integrity rests on the invigilated room — named seats, designated invigilators, convocations and a session report — backed by granular roles and an audit log of grade changes, exports and permission grants. This article is an evaluation grid for institutions assessing a third-party tool, not a description of an Educati feature.
