Abstract
In order to provide office security for receiving facsimile transmissions, a particular key or password of a receiver of a transmission is sent to the sender. The sender of a facsimile message incorporates the graphic pattern of the key of the receiver in a predetermined location on the first page of the facsimile message which is intercepted at the receiving end by a security reader which looks for the key. If the key is present, the message is placed in storage where it may be retrieved by the receiver by simply keyboarding the password related to the key to retrieve the stored message. If the key is not present, the facsimile transmission is sent on to a standard facsimile machine of the receiver.
