I accepted a new job, and they are initiating a background check through a 3rd party service. That service is asking for my employment history, and my starting+ending salary at each past employer.

Is it reasonable for me to decline to provide the salary information (or to fill in $0 in each field if it's required)? I didn't provide my current salary to them in negotiations (so I have no need to "prove" it to them), and I do not want my salary data to be present in yet another online system (that will probably be hacked at some point so my salary data will be publicly accessible in a .torrent data dump).
