# Duplicate Suppression
**Domain:** Deep Time / Digital Removal / Copy Control
**Doc Type:** Canonical Wiki Entry
**Maturity:** Developed
**Evidence / Concept Status:** Established technical/legal capability
## Definition
**Duplicate Suppression** is identification and removal of copies considered identical or sufficiently matching a prohibited digital object.
## Why It Matters for Deep Time Continuity
If copied processes can diverge into separate subjects, duplicate suppression becomes a population and personhood question.
## Existing Architecture / Evidence
TAKE IT DOWN requires removal of known identical copies; other systems use hashes, fingerprints, and matching technologies.
## Deep-Time Continuity Analysis
Deep-time systems must define when identity similarity ceases to justify collective treatment.
## Evidentiary Boundary
A current identical-image copy is not a person; the concern arises under changed ontology.
