What is the term for the action of correcting or removing information?

The term that describes the action of correcting or removing information is "redact." This action is commonly used in legal and governmental contexts, where sensitive information is systematically removed or obscured from documents to protect privacy or confidentiality.

Redacting involves more than just correcting; it specifically refers to the careful process of editing a document to ensure that certain information is not disclosed to unauthorized individuals. This could include names, addresses, financial information, or other private data that needs to be safeguarded.

In contrast, terms like "correct," "amend," and "react" have different meanings. "Correct" typically implies making accurate changes to rectify errors, while "amend" refers to making changes or additions to improve or modify a document. "React" pertains to responding to a situation and does not relate to the removal or editing of information. Thus, "redact" is the most precise term for the action described in the question.
