WITI Certify (codename: QRPRUF) is the high-security cryptographic flagship of the Sanadidari Trust Ledger. Designed for LegalTech and institutional environments, it provides iron-clad Zero-Trust certification of events, people, and locations.
It bridges the gap between field evidence (Media, Audio, Metadata) and institutional integrity through a "Certification-by-Design" architecture.
At its core, WITI Certify operates on a local-first security model:
- On-Device Hashing: Every byte of evidence (Image, Video, Audio) is hashed and signed locally using AES/SHA-256 before being pushed to the institutional cloud.
- Multi-Factor Biometric Vault: Integrated hardware-level biometric authentication (
local_auth) to ensure that only certified agents can sign missions. - Trusted Time & Space (GPS Anti-Spoofing): Advanced cross-referencing between network timestamps, device internal clocks, and satellite GPS coordinates to prevent spoofing of "Presence".

- Framework: Flutter (Latest Stable)
- Architecture: Feature-Driven Design with Riverpod 3.0 (Codegen) for a fully reactive, high-performance state.
- Vision Intelligence: Automated document verification using Google ML Kit Vision API (OCR & Document Scanner).
- Video Optimization: On-the-fly hardware-accelerated compression (
video_compress) for efficient institutional bandwidth management. - Deep Linking Integration: Support for
app_linksenabling seamless transition from institutional emails or dashboards directly into the certification vault.
WITI Certify is the specialized certification layer that integrates with WITI Field (NOUR) and is managed by the WITI Governance Engine.
