DHS/ALL/PIA-055 DHS Data Analysis Tools

The Department of Homeland Security (DHS) Office of Intelligence & Analysis (I&A) is developing, deploying, and using Data Analysis Tools (DAT) to perform enhanced analysis of DHS datasets and other data sources available to DHS in support of its homeland security mission. This Privacy Impact Assessment (PIA) examines the privacy implications of DATs, as they will analyze data sources that contain personally identifiable information (PII), and describes the types of tools the Department may develop, how the tools will use data, what sources of information the tools will use, how information will be protected when it is used in DATs, and the oversight process for DAT deployment. In addition, this Privacy Impact Assessment describes testing environments on the unclassified and classified DHS networks that I&A will use to facilitate the development and testing of DATs. DHS is updating and replacing the original Privacy Impact Assessment to capture technological and programmatic evolutions since it was first published in 2016. June 2023
