Nagpur-based deep-tech startup SecureExam Tech has developed Sentinel Lockers—an AI-powered IoT vault system designed to prevent leaks and tampering of exam papers and forensic evidence. Deployed across exam centers and police stations in Maharashtra, the solution addresses critical vulnerabilities in high-stakes testing and evidence storage through biometric authentication, real-time tracking, and blockchain-backed audit trails.
Founded in 2023 by IIT-Nagpur alumni Rahul Deshmukh (CEO) and Priya Sharma (CTO), SecureExam Tech aims to restore trust and fairness in India’s examination and law enforcement systems using homegrown technology aligned with the Atmanirbhar Bharat and Digital India initiatives.
How Sentinel Lockers Work
Core Security Features
- Biometric Authentication: Combines fingerprint and facial recognition for access control.
- Vibration & Tamper Sensors: Detects unauthorized movement or forced entry.
- GPS Tracking: Monitors locker location in real time during transit.
- Blockchain Logging: Immutable records of access and movement for audit trails.
- Edge AI Analytics: Identifies suspicious behavior patterns (e.g., repeated access attempts).
Operational Workflow
- Pre-Exam Sealing: Exam papers are sealed inside lockers with encrypted RFID tags.
- Transport & Storage: Lockers are tracked en route to exam centers or storage facilities.
- Breach Alerts: Authorities receive instant notifications via a centralized dashboard if tampering is detected.
- Post-Event Audits: Blockchain logs provide verifiable proof of integrity.
Impact and Performance Metrics
Pilot Results in Maharashtra
- Reduced Leaks: 95% decrease in paper leak incidents during trials.
- Scalability: Units cost ~₹5,000 each, enabling large-scale adoption.
- Adoption: Deployed for 10,000+ exams across Nagpur and Pune.
Use Cases
- Education Boards: Securing question papers for state and national exams (e.g., CBSE, state boards).
