[MARVEL] Superhuman Registration Act: Did superheroes have to unmask themselves to the government only? Or was it public knowledge who these people are?

My friend thinks that those unmasked had privacy from the public. I thought the issue was that the world would know who these people are?

Unless the information were classified, a Freedom of Information Act request would provide it.  Even if it were classified, 'anonymous sources' would probably be sufficient for the press to find out, and the the information would no doubt be valuable -- think TMZ for the Cape and Cowl crowd.   

On the other side, for the Cape, if only the government knows, then they still have to go through all the effort of preserving a secret that is no longer secret - all the while their family and friends could be compromised by any of the host of villains skilled at espionage.  Why not go full public, like the Fantastic Four, plus get the benefit that now your family and friends know and can protective steps. Even better, those loved ones should be eligible for government provided security, such as the Guardsmen, who are basically Iron Man Lite.
