Censor bars
Basic form of censorship
From Wikipedia, the free encyclopedia
Censor bars, also known as black bars, are a form of text, photography, or video censorship in which sensitive content is occluded by rectangular monochrome boxes.[1][2] Since the creation of digital editing software which can apply less obtrusive effects such as pixelization and blurring, censor bars are typically used for satire.[3][4] but remain in use to address privacy concerns. Censor bars are also used in art forms such as blackout poetry.
Censor bars may also have the words "censored", "redacted", "private information", "sensitive information", etc. to indicate their presence. Alternative methods of obscuring content include overlaid images such as fig leaves.
