Abstract
The present invention allows the user (author or creator) of a document to specify that certain portions of a document be selected for encryption while other portions of the document remain displayed as created. The user could employ a standard word processing editor technique to highlight (or swipe) portions of a document that the user desires to be encrypted. The highlighted portion would then be ‘tagged’ with a surrounding attribute indicating to the word processor that this highlighted portion of the document is to be encrypted. This process is similar to the existing word processor capability to highlight areas on a document and then assign rich text attributes, such as BOLD, ITALICS, etc., to those areas. With proper authorization, any encrypted portion of a document would be displayed as part of the document. Without proper authorization, the display of the document would only contain the unencrypted portions of the document.
