Death Files
It seems to me that publishing the Death Files and making them completely available to all who register credit applications, or process voting records, etc, would eliminate the ruse of registering dead persons as new accounts or voting as a deceased person, or NEW VOTERS! This would make these practices unusable: ALL new (possibly even all OLD) accounts would be checked against this easily accessable list, and if someone were deceased, no NEW accounts, no NEW poll list entries, would be generated! The only drawback I see is that if someone still living were listed as dead (this HAS happened, by the way) he/she couldn't use their accounts! Therefore, safeguards against unauthorized data entry should be extremely stringent!
