Pseudonymization

Pseudonymization preserves analytic utility that anonymization destroys: records about the same person remain connectable, which matters for longitudinal work. It also remains personal data under most regimes, because the link can be restored with the key — a distinction organizations routinely blur when describing their controls. In retrieval systems it is useful precisely because it keeps a corpus coherent while removing the names an answer would otherwise surface.

Where pseudonymization is appropriate, Centralpoint applies it as part of the ingestion transformation, so the index holds the surrogate rather than the identifier. Because the rule is a record with version history, what was being pseudonymized during any given period is establishable rather than recalled.
