Currently, we have a Excel spreadsheet in which a tab contains a database like of information (both sensitive & non-sensitive) on a particular topic. From this database, we devleoped Excel's Pivot Table. In order to share that data, we develop a Pivot Table on that same spreadsheet revealing non sensitive informaiotn We made a copy of that spreadsheet and place it on a New Book (i.e. another spreadsheet). We send that new spreadsheet to other via outlook. When the recipient of that email receive and open the attachment, he will simply only see that pivot table as a single tab. However, the recipient can double-click on a figure in that Pivot Table and see the information from the complete database (both sensitive and non-sensitive) informaton. We did not anticipate this action. As a added security measure, we had the original database on a secured subfolder on our network. And yet the recipent was able to see the (what we thought) was secured data. Any helpful hints in preventing the linkage to the original databse of information?
