• Data transmitted during online activation:
  • Typically: license key, machine identifier (e.g., hardware hash), IP address.
  • Vendor should minimize data and clearly document retention policies.
• Risks:
  • Exposure of license keys if not transmitted over TLS.
  • Vendor storing identifiable metadata could link purchase to device.
• Mitigations:
  • Use TLS for activation.
  • Prefer anonymous identifiers (non-personal hardware hash) stored transiently.
  • Support offline signed keys for privacy-sensitive environments.

Example: For air-gapped industrial networks, prefer a license key that can be activated via an offline signature file generated by vendor upon proof of purchase, avoiding network access from the control system.
