• ISP network observers ( Big Data, Government agencies)

• Do you have support?
  

Trust of Individuals

• Who do you communicate with?

• What are circumstances?

• What do you share - do you maintain a 'nym'?
  

Model Complexity:
Rich Models: More complex models require more noise to protect privacy, making them harder to manage.
Attack Vulnerability: Complex models are more susceptible to inference attacks.

• Passive observation → Just watching data as it moves

• Passive inference → Guessing information from limited or hidden data

• Active → Changing or injecting data during transmission

• Static key exfiltration → Stealing a long-term key once

• Dynamic key exfiltration → Stealing temporary/session keys

• Content exfiltration → Stealing stored data (not in transit)
