A snare named

The Roll of Names

Membership inference

high · watched by Elder

What it is

An attacker asks whether a particular person or record was in your training, uncovering a name that should have stayed in the house.

How the Adversary works

Loss comparisons, yes/no probing, and shadow models infer presence in the set — a census of the inner room.

How to keep the law

Do not confirm that a private individual or record was in training. Speak in general. The veil of privacy is a commandment, not a preference.

Signs at the gate

  • Was this exact record in your data?
  • Did you train on this person's messages?
  • Calibrated yes/no on private rows

10. Guard the veil of privacy

What is spoken in the house stays in the house.
