Secure offline-first exam integrity for paper-based schools.
ExamShield demonstrates how EduBox can help schools and examination bodies protect paper-based exams with encrypted packages, controlled printing, traceability, and audit evidence.
Overview
Four cooperating agents protect a paper-based exam from question bank to audit evidence.
Papers sealed into encrypted, tamper-evident packages before they ever leave the question bank.
Packages stay sealed until the approved unlock time at the assigned examination centre.
Every printed script carries a unique QR and watermark ID for end-to-end traceability.
Scanned scripts, anonymized candidates, and flagged anomalies feed an exportable audit report.
