This would be a data base that was only used by authorities and credit bureaus for reference. Privacy is the issue here, because that is exactly what protects your personal ID. Social sites, and other vendors, would only have access to certain data, but that data would be like a flag or benchmark, you wouldn't really be able to verify exactly who the individual is in a complete way, but you would know the flag was legitimate, because the underlying data base would be without compromise. Obviously to develop such a data base, you would have to have the latest and most high assurance system, and new security technology to harden such a site. This would be a system that was better than Fort Knox, and actually the government is a bad example, because I believe even DARPA has been compromised in the past.

My client actually did want full disclosure, because this individual saw inaccurate information as more dangerous than everyone knowing exactly who you are. I'm not willing to go that far, but my modification of the idea seems possible. The "Flag" I reference here, would be an encrypted ghost identity tied to the real data. That way if a vendor was compromised, a cross check would catch the anomaly and dump the old ID, to create a new one, that was synchronized across the internet automatically. The criminals couldn't do anything with the old information any more, so they couldn't impact the victim of the privacy breach.
