Digital Immunity for the U.S. Supply Chain
Presentation on preventing data loss in moving vehicles through durable edge capture, replay-aware ingestion, and deterministic digital twin reconciliation.
This presentation introduces the concept of Digital Immunity for mobile IoT systems in supply chain logistics. It was presented at FRUCT 39 as part of the connected systems track.
Digital Immunity is defined as the ability to preserve integrity, completeness, and recoverability of edge-generated operational data despite mobility-induced disruption — reframing resilience from connectivity restoration to provable continuity of operational history.
The reference architecture spans four layers: vehicle edge (durable capture and checkpointing), in-transit connectivity (adaptive transfer), cloud ingestion (replay-aware, idempotent processing), and digital twin reconciliation (gap detection and deterministic convergence).
Prototype evaluation across disruption scenarios including 2-hour blackout, edge power loss, and forced twin divergence showed 0 events lost and 100% recovery completeness with convergence in 2.1–4.4 minutes.
