# Identity Intelligence **Entity class:** Intelligence discipline and fusion function **Domain:** Counterterrorism / biometrics / identity analysis **Aliases:** I2 **Maturity:** Developed ## Definition **Identity Intelligence (I2)** integrates biographic, biometric, behavioral, documentary, contextual, and reputational information to resolve a person or other identity and connect it to people, places, events, organizations, devices, accounts, and materials. Its central questions are: **Who is this? Is this the same person seen elsewhere? Who or what is connected to them?** Identity intelligence supports screening, targeting, investigation, border security, fraud detection, and network analysis. The operational value depends on provenance and entity resolution; a false merge can attach another person's relationships and risk signals to the wrong identity. ## Relationships - **method:** [[wiki/Identity and Relationship Analysis|Identity and Relationship Analysis]]. - **repository:** [[wiki/Terrorist Identities Datamart Environment|TIDE]]. - **data operations:** [[wiki/Entity Resolution|Entity Resolution]] and [[wiki/Link Analysis|Link Analysis]]. - **cycle:** [[wiki/F3EAD|F3EAD]]. - **historical DHS implementation:** [[wiki/ICEPIC|ICEPIC]]. ## Sources / Provenance - [NCTC — 2017 remarks on TIDE and identity management](https://www.dni.gov/files/NCTC/documents/news_documents/CNASopeningremarks.pdf) - [DOJ Office of Inspector General — TIDE identity merge and quality](https://oig.justice.gov/archives/reports/FBI/a0741/findings.htm)
