MQTT Privacy & Exposure Analysis

Analysis of privacy features and exposure risks when packet is shared via MQTT

Exposure Level: Broadcast

Privacy Features:

✓ Direct LoRa transmission (not via MQTT)
✓ Custom channel: MediumSlow
✓ Gateway node ID tracked
✓ Reduced position precision: ~2900.0m accuracy

Exposure Risks:

⚠ Visible to all nodes on channel
⚠ Packet visible to MQTT subscribers
⚠ Multi-hop path visible (1 hops)
⚠ RF signal metrics exposed (location inference possible)
