The term “identifiers” is NSA jargon for information relating to an individual, such as telephone number, email address, IP address and username as well as their name.
The document – which is undated, though metadata suggests this version was last updated in June 2012 – does not say whether the oversight process it mentions has been established or whether any searches against US person names have taken place.

Perhaps foolishly, but I find it amusing that metadata is being used to evaluate how/when other metadata identifiers were being used to track the world’s populations…
