Secure Client Ingestion

Frontend Applications

Ingestion Mechanics

Users record traffic safety incidents via cross-platform apps built using Flutter. Before any media is transmitted, the client requests a secure session from the backend, bound to cryptographically attested device states.

Security Attestation

  • Android: Play Integrity API verifies a genuine, untampered device and boot state.
  • iOS: App Attest binds keys directly to the physical Secure Enclave.
  • Web: reCAPTCHA v3 validates interaction scoring to block automated bot requests.
  • XR Emulator: Standardized mock streaming structures for smart glasses integrations.

Core Infrastructure Pillars

🔒 Zero-Trust Ingress

No backend API routes are accessible without cryptographic validation. Cloud Armor filters requests at the network edge while App Check token verification ensures all clients are validated before read/write permissions are granted.

💨 Edge Delivery & Caching

95% of public feed requests are absorbed by Cloud CDN at the edge. The Go proxy forces ETag revalidation for client JS files while allowing browsers to cache immutable assets, maintaining sub-millisecond feeds during viral traffic.

📦 Multi-Tenant Isolation

Firestore databases are logically partitioned. Enterprise licensees operate on isolated database instances and cloud storage buckets, ensuring zero cross-tenant contamination while maintaining a unified backend deployment stack.
