This move actually makes a lot of sense, and it's shameful that the US government has failed to implement this already. As far as security goes, there's no reason why the system can't be built securely. It's simply a matter of building constraints around who gets to access what data, for what reasons, and what procedures are necessary to grant that access.<p>It's not like the US government's current systems have any sort of robust security in place. Centralization will hopefully incentivize this effort.
