Systems and methods for redacting portions of a document resulting in one
or more versions of the document that show to readers the portions of the
document that have been redacted. At least one of these one or more
versions may have the content of the redacted portions encrypted and/or
actually removed and replaced with a sort of filler (e.g., to resemble a
blacked out portion of a paper copy). At least one other version may show
to users the actual content that has been redacted. This latter version
may be retained for users privy to the content (i.e., information) of the
redacted portions, so that they know what content was redacted, whereas
versions with the content removed or encrypted may be provided to those
not privy to the content.
