About the "complicated nature" of Obama's personal information

As Time Magazine reported;
“Over the weekend and in advance of today’s deadline, the President enrolled in a health care plan made available by the Affordable Care Act on the DC marketplace,” the aide said. “As you all know, the President is one of the 85 percent of Americans who gets his health insurance through his employer and, like previous Presidents, is privileged to receive health care from the military.  The act of the President signing up for insurance coverage through the DC exchange is symbolic since the President’s health care will continue to be provided by the military.  But, he was pleased to participate in a plan as a show of support for these marketplaces which are providing quality, affordable health care options to more than a million people.  The President selected a bronze plan.”
The aide added that Obama only signed himself up, and not the rest of the First Family. Obama also did not enroll through the troubled Healthcare.gov or the D.C. exchange’s website. Aides signed him up in person over the weekend, due to the “complicated nature of the President’s case,” the White House aide said. Some of Obama’s personal information is not readily accessible on the government databases used by the website for identity verification.
Could we go into “complicated nature of the President’s case,” a bit further? Why is the President's personal information not in government databases? You mean to tell us he doesn't have a real birth certificate or a valid social security number? Just asking. Or is he just afraid to put his personal identification on the DC exchange where it might get hacked and then we could possibly have a non citizen in the White House signing bills and making political appointments?
