The challenge

Sensitive documents are often shared through channels that make copying, extraction and uncontrolled redistribution easy. SEAL X explored a controlled workflow that separates document preparation from document consumption.

Approach

The system was designed as two applications with distinct responsibilities: a Composer for preparing protected documents and a Viewer for authorized access. The implementation explored AES-256 encryption, authenticated access, logging and restricted document handling.

What this project demonstrates

  • Translating security objectives into product behaviour
  • Working with encryption and authentication concepts in a usable workflow
  • Designing separate trust boundaries for administrative and end-user actions
  • Treating auditability and user experience as part of security
