DTX_ID — Universal Person Identifier
DTX_ID is AI CDP's universal person identifier — analogous to LiveRamp's RampID. It represents the actual person, not the account holder.
The Spouse Scenario
Ahmed holds PartyID P001 with two MSISDNs. He uses one; his spouse uses the other. Billing sees one account, but AI CDP creates two DTX_IDs — D001 (Ahmed) and D002 (Spouse) — via behavioral signals.
Properties
- System-generated UUID v4, immutable once created
- Pseudonymous token — not PII itself
- Hash/token stored; mappings secured separately
Generation Rules
| Scenario | Action |
|---|---|
| New identifier, no match | Generate new DTX_ID |
| Identifier matches existing | Return existing DTX_ID |
| Two parties confirmed same | Merge — surviving DTX_ID wins |
| Party confirmed as multiple | Split — new DTX_ID for split-off entity |

Industry Comparison
| ID Type | Scope | AI CDP Equivalent |
|---|---|---|
| LiveRamp RampID | Cross-publisher | DTX_ID (internal) + UID2 (external) |
| UID2 | Programmatic | Generated from consented email |
| Telco MSISDN | Single identifier | One of many Identifiers linked to DTX_ID |
info
DTX_ID is the internal truth; UID2/EUID are external activation tokens.
