# 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.
