System description
Each quarter, BDM provides MSD with an encrypted CD of all name change records from January 2009 to the extract date. The name change details include the full name at birth, former full name, new full name, birth date, residential address, and country of birth. 

MSD compares the name change records with MSD client records to identify clients who have registered a name change and not advised MSD of the new name. The matching process produces positive matches that are weighted to indicate the probability that an MSD client is the person on the Name Change Register. 

If MSD finds any discrepancies, these are manually verified before any action is taken, including sending notices of adverse action. From time to time MSD may conduct investigations using the results of a match if fraud is suspected.
