I have an split Access database (mdb) that has just been moved to Access 2010 but kept as an mdb. In the main table there is a field that holds a Social Security Number. The new head of IT is concerned that this field has just been sitting out there on the network (rightly so) and wants to encrypt it. I have no experience with working with it at that level. Can anyone tell me if it is possible in either Access 2003 or Access 2010, mdb or accdb to do this? If so, can you tell me how? The field is not an ID field and only shows up on the form and possibly on a report.
