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

The term "redact" specifically refers to the process of editing a document to remove or obscure sensitive information before publication. This is commonly used in legal and governmental contexts, where certain data might need to be concealed for privacy or security reasons. Redaction can involve blacking out or removing text, ensuring that confidential details are not disclosed to unauthorized individuals.

The other terms, while related to changes or modifications, do not encapsulate the same level of specificity as "redact." For example, "correct" generally means to make something right or accurate, but does not imply the removal of information. "Amend" refers to making changes or improvements but similarly does not carry the connotation of removing content. "React" involves responding to a situation, which is completely unrelated to the act of modifying text or information.
