TWPDES 3.0 Description

Terrorist Watchlist Person Data Exchange Standard (TWPDES) 3.0 acts as a comprehensive standard for exchanging and sharing known or reasonably suspected terrorist (KST)-related information across the federal, state, local, territorial, and tribal law enforcement intelligence community and among international partners. These standards are flexible and can be tailored to meet specific domain mission(s) without the necessity of extensive workarounds.

One of the goals of TWPDES 3.0 is to provide both biographic and biometric data in a single unified message. Using these two types of data together can substantially improve the performance of identification and verification of KSTs.
NIEM Domain Content

The primary design objective of the biographic and biometric data format in TWPDES is to allow information to be exchanged between agencies, while leveraging existing standards and anticipating future standards and new biometric modalities as much as possible. Consequently, TWPDES 3.0 utilizes existing American National Standards Institute (ANSI)/National Institute of Standards and Technology (NIST)-Information Technology Laboratory (ITL) Biometric Standards Part 2, National Information Exchange Model (NIEM) and TWPDES.

TWPDES 3.0 leverages layered schema architectural principles, which allows the scope of TWPDES to expand and additional mission areas to be accommodated without polluting the pure person and identity abstractions defined in the earlier versions of TWPDES. These additional mission domains are supported through layered abstractions and schemas, which are described as subordinate component specifications within TWPDES 3.0. Example mission areas include Encounter Management, Watchlisting, and future domains, such as Redress Management.
