Securing Online Examinations

Question papers that cannot be leaked — because a complete paper never exists in one place until the moment the exam begins.

The Challenge

One leaked paper undoes the whole exam

Question papers are among the most sensitive documents an institution handles. A single leak — from a compromised server, an insider, or an intercepted transfer — invalidates the exam, triggers re-tests, and damages credibility. Traditional encryption still stores the entire paper in one location, so one breach exposes everything.

KVault takes a different approach. Its US-Patented Split & Spread technology fragments each paper and distributes the pieces across multiple locations. No single store ever holds a usable paper. The complete document is assembled only in volatile memory (RAM), only at exam start — and purged the moment the exam ends.

How It Works

A seamless workflow — from upload to student access

KVault: A Risk-Free Approach to Online Examinations — secure infrastructure setup and the examination lifecycle — Secure infrastructure setup and the full examination lifecycle — from collaborative paper selection to localized student access.

Preparation

Exam authority uploads the question papers.

Encryption

Each paper is auto-split into encrypted fragments.

Distribution

Fragments spread across Cloud 1, Cloud 2 & local storage.

Assembly

Reassembled in volatile RAM — only at exam start time.

Access

Delivered to a secure local session for students.

Purge

Fragments deleted post-exam — zero trace left behind.

Why It Matters

Leak-proof by design

No single point of compromise

No storage location ever holds a complete, usable paper — one breach exposes nothing.

Papers never stored whole

The full paper exists only in RAM, only at exam time — never written to disk intact.

Time-gated assembly

Reassembly is triggered at the scheduled start, so early access is impossible.

Zero-trace purge

Fragments are destroyed after the exam, leaving nothing to leak later.

Integrity across centres

Distributed exam centres stay in sync without exposing content in transit.

DPDP & audit aligned

Provable, controlled handling of sensitive assessment data.
