How Proctoring Platforms Detect and Prevent Cheating?

Remote exams are convenient. But are they secure?

The rise of online education and remote assessments has brought unprecedented convenience but also new challenges in maintaining academic integrity.

Without the physical presence of an invigilator, how can you ensure test-takers are following the rules? How can organizations maintain the same level of exam integrity remotely as they do in-person?

As cheating methods grow more sophisticated, proctoring platforms have evolved to counteract them using advanced technologies like AI, biometrics, and behavioral analytics. 

This blog explores how these platforms detect and prevent cheating, ensuring fair and secure exams. Cheating methods have evolved with technology:

• Impersonation: 23% of remote test-takers admit to using fake IDs or hiring proxies
• Content Leaks: 56% of exam questions appear on sites like Chegg within 1.5 hours of testing 
• AI Abuse: ChatGPT and paraphrasing tools bypass plagiarism detectors by 68% 

How Proctoring Platforms Detect and Prevent Cheating? (Step-by-Step)

Step 1: Secure Test Environment Setup

Before the exam even begins, the proctoring platform establishes a secure environment:

• Browser lockdown: Prevents tab-switching, copy-paste, or external app access
  
• Device check: Detects secondary screens, virtual machines, or remote access tools
  
• Identity verification: Candidates upload a government ID and take a selfie for face match
  

Step 2: AI-Based Candidate Monitoring (Live or Async)

Once the test begins, AI-powered systems take over:

• Webcam Monitoring: Continuously checks for multiple faces, background movements, or candidate absence.
  
• Eye Movement Detection: AI flags frequent looking away from the screen or unnatural gaze patterns.
  
• Facial Recognition: Ensures that the registered candidate stays in frame and no one else appears.
  
• Voice Detection: Detects suspicious sounds or whispers that may indicate external help.
  
• Audio Recording: For speech-based cues or unusual room noise.

Step 3: Tab and IP Monitoring

To prevent online searches and collaboration:

• Tab-switch detection: Every time a candidate switches tabs or windows, it’s recorded and flagged.
  
• Clipboard Monitoring: Prevents copy-pasting from or to the test.
  
• IP address tracking: Detects if multiple candidates are using the same network or location — a potential sign of collusion.
  
• Geolocation cross-verification: Ensures consistency between declared and real-time location.
  

Step 4: Real-Time Alerts and Live Proctor Escalation

When anomalies are detected:

• The system raises real-time alerts.
  
• A human proctor (in live proctoring) can intervene — pausing or terminating the test.
  
• In asynchronous mode, recordings are reviewed later by trained auditors.
  

Flag Types:

• “Red” = confirmed malpractice (e.g., person switch)
  
• “Orange” = suspicious behavior (e.g., excessive tab switches)
  
• “Green” = no issues detected

Step 5: AI & Human Review for Fairness and Finality

Post-exam, the platform generates:

• Detailed proctoring reports: Highlighting flagged behavior with video and audio evidence
  
• Trust scores or integrity scores: Calculated based on behavior, system logs, and AI detection
  
• Cheating summary dashboards: For large-scale exams, visual analytics help identify widespread issues or suspicious patterns

Top 5 Strategies to Prevent Cheating

1. Combine AI with Human Review

Modern proctoring platforms integrate AI-based monitoring with live or recorded human proctoring to maximize security. AI algorithms continuously flag suspicious activities such as:

• Multiple faces detected in the camera view
• Absence of the candidate from the frame
• Eye-gaze deviations indicating potential use of unauthorized materials
• Unusual background noise suggesting assistance

However, AI alone can sometimes generate false positives due to lighting, movement, or device glitches. Live proctors or human reviewers validate these AI flags in real-time or post-exam to ensure fairness and accuracy.

This layered approach prevents cheating effectively while avoiding penalizing genuine candidates for benign anomalies.

2. Use Multi-Factor Authentication

Identity fraud remains a major threat in online assessments. To prevent impersonation:

• ID Verification: Candidates are required to upload official government-issued ID for pre-exam validation.
• Biometric Checks: Face recognition compares live photos with ID images. Advanced systems add liveness detection to prevent spoofing through photos or videos.
• Behavioral Biometrics: Keystroke dynamics (typing rhythm), mouse movements, and voice recognition further authenticate candidates, making it nearly impossible for someone else to take the exam on their behalf.

Implementing multi-factor authentication ensures robust identity verification at multiple touchpoints before and during the test.

3. Implement Strict Time Limits

Studies show that unproctored exams often take nearly twice as long due to candidates searching for answers or seeking help. To curb this:

• Set realistic yet strict timers per question or section.
• Limit navigation and prevent backward movement if possible.
• Combine time limits with question randomization to eliminate collaboration and answer sharing among candidates.

Strict time management enforces focus, reduces the window to cheat, and simulates real-world decision-making under pressure.

4. Adopt Authentic Assessments

Traditional multiple-choice questions (MCQs) are vulnerable to cheating through simple web searches or question bank sharing. Instead, implement:

• Performance-Based Tasks: Coding challenges with live screen recording, system design whiteboarding, or data analysis tasks.
• Video Demonstrations: Ask candidates to explain solutions verbally on camera to assess understanding and communication.
• Real-World Scenarios: Problem-solving based on authentic work situations rather than theoretical recall questions.

Authentic assessments measure practical competencies and critical thinking, reducing the effectiveness of cheating tactics and improving hiring quality.

5. Educate Candidates

Many candidates cheat out of anxiety, fear of failure, or unfamiliarity with online proctoring protocols. Addressing these concerns can reduce the intent to cheat:

• Clear Guidelines: Communicate strict proctoring rules, data privacy policies, and consequences of violations transparently before the test.
• Practice Tests: Provide mock exams under proctored settings so candidates can test their devices, internet stability, and become comfortable with monitoring tools.
• Support Channels: Ensure technical support is available during tests to resolve genuine issues that might otherwise trigger panic and unethical behaviour.

An informed, confident candidate is less likely to engage in dishonest practices during assessments.

By integrating advanced AI monitoring, human oversight, multi-factor identity verification, authentic assessment design, and candidate education, organizations can significantly reduce cheating while ensuring a fair, secure, and stress-free assessment experience for all candidates.

Addressing Ethical Concerns in Online Proctoring

1. Bias Mitigation

AI-based proctoring systems can unintentionally disadvantage certain candidate groups if not designed inclusively. To address this:

• Regular Bias Audits: Conduct periodic assessments of AI algorithms to identify and rectify any biases against non-native speakers, neurodiverse individuals, or candidates with different cultural expressions.
• Inclusive Training Data: Ensure AI models are trained on diverse datasets that include variations in skin tones, accents, physical abilities, and behaviours to improve accuracy and fairness.

By prioritizing bias mitigation, institutions uphold equity and inclusivity while maintaining exam integrity.

2. Transparency

With rising concerns around surveillance and privacy, transparency is critical:

• Clear Communication: Inform candidates about the data collected, how it will be used, who will have access, and how long it will be retained.
• Regulatory Compliance: Comply with data privacy regulations such as GDPR (EU), CCPA (California), and Local Law 144 (New York City), which mandates informing candidates about automated decision-making tools used in hiring or assessments.

Transparent practices build trust and reduce candidate anxiety, improving overall test experience and brand reputation.

3. Accessibility

Not all candidates have equal access to technology:

• Camera Alternatives: For candidates unable to use webcams due to hardware limitations or privacy constraints, offer options such as voice verification, keystroke biometrics, or supervised in-person centres where feasible.
• Assistive Technology Support: Ensure proctoring platforms are compatible with screen readers, speech-to-text tools, and other assistive technologies to support candidates with disabilities.

Accessibility-first design ensures fair opportunities for all test-takers while meeting global standards of inclusivity.
