# PRISM Surveillance Program PRISM is the public codename associated with provider-assisted, or “downstream,” collection under [[FISA Section 702]]. Authorized selectors are directed at non-U.S. persons reasonably believed to be abroad, and qualifying U.S. communications providers are compelled to assist. ## Notebook evidence [[Scanned_20260730-1830]], PDF page 4, places PRISM alongside Room 641A, AT&T, the Special Collection Service, and STELLARWIND. The grouping correctly identifies a surveillance-infrastructure family but not a single technical or legal system. ## Distinction PRISM is not synonymous with upstream network acquisition, [[Room 641A]], or [[STELLARWIND]]. A useful model has two axes: **technical collection position** and **legal authority**. ## Boundary Provider participation in the program does not establish that a particular person, account, or communication was collected. ## Source - [[Scanned_20260730-1830]], PDF page 4.
