Primes¶
- Identifiability
- The same dual structure governs cryptographic indistinguishability (plaintexts kept in one large class given ciphertext) and k-anonymity (each record made indistinguishable among at least \(k\)).
This sourceDefines k-anonymity: each record made indistinguishable among at least k — a minimum-size equivalence-class privacy guarantee.

- Vouched Anonymity
- Protection is the size of the surviving set, which makes concealment a quantity rather than a state, and is why deleting a name changes nothing once the intersection is a singleton.
This sourceShows that combinations of a few quasi-identifying attributes often single out individuals, so data stripped of explicit identifiers can still be re-identified by linking, and defines protection as indistinguishability within a set of at least k records.

Mechanisms¶
- Threshold Suppression
- The underlying principle is k-anonymity: each released record should be indistinguishable within a group of at least k, and small-cell suppression is one way to enforce it.
This sourceDefines k-anonymity so each quasi-identifier value sequence appears at least k times in released data.

Verification¶
This reference passed the adversarial substantiation pipeline: it was checked to exist and to support the claim it is attached to. See how references were verified.
