MQTT Privacy & Exposure Analysis

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

Exposure Level: Broadcast
Privacy Features:
  • βœ“ Direct LoRa transmission (not via MQTT)
  • βœ“ Custom channel: MediumSlow
  • βœ“ Gateway node ID tracked
  • βœ“ Reduced position precision: ~729.0m accuracy
Exposure Risks:
  • ⚠ Visible to all nodes on channel
  • ⚠ Packet visible to MQTT subscribers
  • ⚠ Multi-hop path visible (3 hops)
  • ⚠ RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
Gateway ID: !ae617960
Position Precision: 15 bits (~729.0m accuracy)
Position precision meters: 729.0
Signal Metrics: RSSI: -66.0 dBm
SNR: 8.75 dB
