Overview

Report data from key workstations through hardware signing at device level, aggregate through gateway for anomaly detection, and anchor on-chain to support audit replay.

Challenges
  • Inconsistent data standards across multiple workstations and systems
  • Risk of manual operations and log backfilling
  • Insufficient evidence for quality accident accountability
Solution
  1. Device-side private key signing and timestamps
  2. Gateway CBOR normalization and queue buffering
  3. AI anomaly detection and event generation
  4. Merkle tree batch anchoring to chain
Implementation & Integration

Integrate with existing MES/SCADA, add gateway components and API callbacks to form unified evidence chain.

Results & KPIs
  • Anomaly early detection rate +32%
  • Audit time -45%
  • Quality inspection rework rate -18%
