Claims all the personal information on tens of millions of Americans being collected through Obamacare is secure sound less reassuring in light of a massive cyber security breach a few weeks ago.

Hackers, possibly from China, obtained access to personal information about virtually every federal employee. But it was their success in getting into files that should be top-secret, protected by the very best security, that is most alarming.

Detailed files on classified employees of U.S. intelligence services was accessed by the hackers. Those files are much more voluminous than most federal employees’ records. They include very detailed personal information on mental illnesses, arrests, family members and friends.

As we have pointed out, the breach could be a major national security problem.

Before Obamacare was implemented, the White House assured members of Congress collection of information would not have much impact on Americans’ privacy. A Medicare official told lawmakers technology was in place “to minimize all possible security vulnerability.”

But some security analysts have questioned the MIDAS system used as a repository for information collected under the health care law. The system is absolutely critical to the smooth functioning of Obamacare, government officials have said.

How secure is it, really?

Members of Congress should demand an honest appraisal – from outside the government, if necessary. After all, if Washington can’t keep top-secret information under wraps, what is the likelihood it can protect names, addresses, birth dates, Social Security numbers, etc., for tens of millions of people in the Obamacare system?
