Automatic redaction and un-redaction of documents
A method and apparatus for redacting documents is provided herein. During operation, a call is received from a caller and an identity of the caller is determined.

In particular, items such as addresses, phone numbers, times, places, . . . , etc. that are potentially unknown to the caller are redacted so that the called party will not inadvertently disclose this information to the caller.
