Anti-Cheating Real-time Detection

ProctorShield

AI-Powered Interview Cheating Detection

Detect AI interview cheating in real-time on Windows, macOS, and Linux. Catches what video-conference apps can't see — overlay teleprompters, virtual audio loopback, hidden cheat tools, and remote access proxies.

The Problem: Video Interviews Are Vulnerable

Traditional video interviews can't detect candidates using hidden AI tools. Overlay teleprompters like Parakeet AI, Cluely, InterviewCoder, and transparent windows render AI answers invisible to the interviewer.

🎭

Invisible Overlays

Screen capture exclusion hides AI teleprompters

🔊

Audio Loopback

Virtual audio pipes interviewer voice to AI

🖥️

Remote Access

TeamViewer, AnyDesk usage undetected

🔌

Hardware Proxies

KVM switches & HDMI capture cards

7 Detection Engines That See Everything

ProctorShield's native agent runs on the candidate's machine and detects signals video apps physically cannot see.

Engine A

Display Affinity

Detects windows hidden from screen capture

Signals: WDA_EXCLUDEFROMCAPTURE (Win), NSWindowSharingNone (macOS)

Engine B

Window Attributes

Identifies transparent always-on-top windows

Signals: WS_EX_TOPMOST + WS_EX_LAYERED + alpha<1

Engine C

Virtual Audio

Detects audio loopback drivers piping audio to AI

Signals: BlackHole, VB-Cable, Loopback, Soundflower, Voicemeeter

Engine D

Process Telemetry

Identifies known cheat-tool processes by bundle-id

Signals: Parakeet, Cluely, InterviewCoder, FinalRound, LockedIn, Sensei

Engine E

Live Content Capture

Extracts text from overlay windows via accessibility APIs

Signals: Exact AI answer text shown to candidate

Engine F

Hardware & Environment

Detects KVM switches, capture cards, remote access

Signals: TeamViewer, AnyDesk, Parsec, VNC, HDMI capture, VMs, VPNs

Engine G

Browser Extensions

Monitors browser AI extensions & screen-share tools

Signals: Cluely extension, HARPA, Monica.ai, Otter, OBS, Loom

Mobile Room View

Candidate pairs their phone via QR code. Interviewer sees a live 720p WebRTC view of the room + back of the laptop. Zero installation on mobile.

✓ One-tap QR pairing
✓ 720p WebRTC live stream
✓ Works on iOS & Android
✓ Battery-optimized for long interviews
✓ Secure TURN relay for symmetric NAT

Consent-First & Privacy-Focused

Candidate Consent

Plain-English consent screen — Candidate sees exact scope before agent starts
Consent hash recorded — SHA-256 hash logged for audit trail
Every frame carries consent — Backend drops frames without valid hash
GDPR / DPDP compliant — Right to explanation and data deletion

Data Minimization

No screen recording — Only accessibility-tree text from identified overlays
No keystrokes — No keylogging of any kind
No audio bodies — Only metadata about audio system state
Metadata only — Process names, window attributes, hardware events

Security Hardening

Bearer token auth — Recruiter token required on all endpoints
Signed binaries — Authenticode (Win), Developer ID + notarized (macOS)
Security headers — CSP, HSTS, X-Frame-Options
Rate limiting — Prevents abuse with global & per-session limits

Trust Score & Recommendations

ProctorShield calculates a real-time Trust Score (0-100) based on detected signals. Interviewer receives actionable recommendations:

90-100

High Trust

No concerning signals

70-89

Moderate

Minor flags present

50-69

Low Trust

Multiple red flags

0-49

Critical

Strong cheating indicators
