Unlinkability
Privacy
Property where records, actions, or identifiers cannot be reliably correlated to the same subject.
Definition
Unlinkability aims to prevent correlating events or records to the same individual across contexts. It can be supported by rotating identifiers, minimizing metadata, and using privacy-preserving protocols.
In plain English
Property where records, actions, or identifiers cannot be reliably correlated to the same subject.
Why this matters
Why it matters: Linkability enables cross-context profiling even without direct identifiers.
Example
Example: Use per-site identifiers, avoid stable device IDs, and limit shared metadata that supports correlation.
