ObamaCare’s federal exchange…has to bring together information about you and your family from the Treasury Department and IRS, the Department of Homeland Security, the Department of Justice, as well as your Social Security number — all coordinated by the Department of Health and Human Services.
Similar information is collected when you apply for a mortgage. But when the constantly updated information is combined in a central data hub, the potential for abuse is staggering. For one thing, the hub will have all the details needed to steal identities and fraudulently access credit.
[T]he federal data will be combined with data streams from state governments. This hub will achieve what has, until now, only appeared in pulp thrillers: a central database linking critical state and federal data on every U.S. citizen for real-time access.
