Word documents can sometimes contain hidden but also visible information that have to be removed before sharing these documents with other users. Tools have been developed to take care of the hidden data (Microsoft Word Metadata Scrubber is one) but until now there were not many tools to take care of visible data that needed to be removed before a document could be shared. Most Word users are therefor replacing confidential text with blanks or single characters like xxxxx which can often times confuse readers of the edited version of the document.
The Word 2007 Redaction Tool has been designed as an add-in for Microsoft Word 2007 to redact text and images in documents before they are shared with other users. The add-in will add a Redact group in the Review tab which can be used to control the process.
To redact text a user would select the text that should be redacted. The next step would be to click on the Mark option in the Redact group in the Word Review tab. This will mark the text by highlighting it. It is also possible to use the Find and Mark command to automatically highlight all instances of a phrase in the Word document. It is possible to review the document at any time before redacting the highlighted text by selecting the Redact Option under the Mark group in the Review tab.
The whitespace character length of each word is altered by 10% (in either direction) to make it harder to guess the correct words. The developer recommends to inspect the metadata of the document to ensure that these do not contain information that could leak the redacted information.
The Word 2007 Redaction Tool can be downloaded from the profile page at Codeplex. It requires the .NET Framework 3.5 Service Pack 1 and the VSTO 3.0 Runtime Service Pack 1 which will be automatically installed should they be missing on the computer system.
