The present invention allows the viewer of a document to select certain portions of an encrypted document for decryption and optionally re-encryption while other portions of the document remain encrypted or as originally created. In this decryption process, the user would use a standard word processing editor technique to highlight (or swipe) portions of a document that the user desires to decrypt. The highlighted area would then be 'tagged' with a surrounding attribute indicating that the highlighted area is to be decrypted. 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. |
