SECURITY & TRUST
Security-First Access Architecture
Cryptographic signatures, strict data privacy, and tamper-proof audit trails engineered for campus security.
Cryptographic QR Pass Signatures
Pass tokens are signed using HMAC-SHA256 hashes. Security guards can validate cryptographic signatures offline even during network drops.
Audit-Ready Movement Records
Every scan, warden approval, and gate entry is logged with a timestamp for institutional audit compliance and historical traceability.
Data Privacy & Isolation
Student and guest data is encrypted at rest and in transit. Strict row-level security controls isolate institutional database tenants.
