Face-Presence Detection That Catches Proxy Test-Takers
Computer vision confirms a face is present from start to finish. Periodic snapshots for human review, presence scoring, and transparent audit trails.
Detection method
False positive rate
Compliant, no biometric IDs
To the candidate
Proof that a person is present, not who it is
Face-presence detection, zero browser takeover.
Enrollment snapshot
Capture a reference face at session start — compared against every subsequent snapshot throughout the assessment.
Computer vision presence detection
Modern computer vision algorithms detect face presence and flag absences. Robust to lighting, angle, and minor occlusion.
Periodic continuity checks
Webcam snapshots at configurable intervals — each compared to the enrollment reference for continuity scoring.
Real-time alerts
Mid-session mismatches trigger interviewer alerts immediately. Review with replay.
Per-signal authenticity score
Face continuity is one of ten integrity signals in the unified authenticity score.
Configurable snapshot storage
Webcam snapshots stored for human review. GDPR-aligned retention policies, no biometric identifiers.
Audit trail
Every snapshot timestamped with confidence score — exportable for compliance review.
Browser-native
Works via the Web MediaDevices API — no extensions, no installs, no plugins.
Consent-first flow
Candidates see a clear consent screen before enrollment. Opt-out is a supported org policy.
Built for how modern teams hire
Face-presence detection, not face recognition
Computer vision confirms a face is present and flags absences, without identifying or storing biometric identifiers. Detects lighting, angle, and occlusion challenges robustly.
- Modern computer vision algorithms
- Robust to partial occlusion (glasses, masks)
- < 1% false positive rate in our tests
Invisible monitoring, clear consent
Candidates are told before assessment that face monitoring is active — compliance requires it. After that, capture runs silently without extensions or disruption.
- Clear consent screen pre-assessment
- No visible indicator during the session
- Configurable capture interval
Snapshot storage that passes legal review
Webcam snapshots are stored for human review with configurable retention. No biometric identifiers are processed, so data regulation is simplified.
- Snapshots for human review (configurable retention)
- GDPR alignment, no biometric identifiers
- Right-to-be-forgotten workflow included
How it works
Candidate consents
Clear screen explains that face-presence monitoring is active. Candidate agrees to proceed.
Reference snapshot
One reference snapshot captured at session start to confirm a face is in frame.
Presence checks throughout
Periodic snapshots confirm face remains in frame — flagging absences in real time.
Review flagged events
Mismatch events surface in the integrity report with timestamp and confidence score.
Frequently asked questions
What technology powers face-presence detection?+
Modern computer vision algorithms detect whether a face is in frame and present, without identifying or storing biometric identifiers. This is presence detection, not face recognition.
Are raw face images stored?+
By default yes — snapshots are stored for human review for configurable durations. This is not a biometric identifier, just visual records. Configurable per org for compliance requirements.
What if a candidate adjusts lighting or wears glasses mid-session?+
Face-presence detection is robust to lighting changes, angle shifts, and occlusion (glasses, minor facial changes). It simply confirms a face is in frame, not whether that face matches an enrollment.
Is face-presence detection GDPR compliant?+
Yes. ClarityHire does not process biometric identifiers — face-presence detection is not face recognition. Clear consent flows, configurable retention, deletion workflows, and audit logging are built in. Check with your legal team for jurisdiction-specific advice.
Can candidates opt out of face verification?+
Yes — opt-out is a configurable org policy. If required by law, candidates can decline biometric capture and your team can choose to proceed with other integrity signals.
