  • DHS/ICE/PIA-049 ICE Parole and Law Enforcement Programs Unit Case Management Systems

    The Parole and Law Enforcement Programs Unit (Parole Unit) within U.S. Immigration and Customs Enforcement (ICE), Homeland Security Investigations, owns and operates three case management systems: 1) the Parole Case Tracking System (PCTS) to process applications and monitor activities related to law enforcement-requested immigration paroles; 2) the S-Visa System for S-Visa immigration benefits; and 3) the Witness Security (WitSec) System to support the witness security program. These are collectively referred to as the ICE Parole Unit Case Management Systems. The personally identifiable information (PII) maintained in these systems is about: 1) aliens otherwise ineligible for admission to the United States who are paroled into the United States in support of law enforcement investigations and activities; 2) aliens either previously removed or currently in removal proceedings who apply for and/or are granted humanitarian parole; and 3) aliens named in applications submitted by law enforcement agencies for participation in the S-Visa and WitSec programs.

  • S&T Behavior Detection Visual Search Task Analysis Project Visual Search Battery Report

    Approximately 1.2 million people fly within the United States every day. To keep these passengers safe, the Transportation Security Administration (TSA) employs a multilayer security system to ensure that the traveling public and the nation’s transportation systems are protected. The Behavior Detection (BD) program serves an essential function in this multilayered security approach. Unique from other security capabilities within the TSA security system, the BD program, which was previously reserved for Behavior Detection Officers (BDOs) but is now comprised of Transportation Security Officers (TSOs) as well, trains officers to identify anomalous behaviors by observing passengers and comparing what they see to an established behavioral baseline. The goal of the program is to identify high-risk travelers and subject them to additional screening. This report describes the results of an empirical study that addressed these research goals and furthered DHS S&T’s understanding of the visual search process required for successful BD performance.
