I've thought of two ways. When Hinata sees through the mask,they wouldn't know it was Obito. That's the first way. But the second way is I still think they'd notice something odd. They'd see more chakra going to eyes and considering how (as far as we know) there are only 2 clans that really do that wouldn't they instantly be like "hold up is that an Hyuuga / Uchiha?" I mean even if they didn't know that's specifically Obito I'd imagine they'd still tell someone what's up. And just knowing that would seem pretty useful. Now the leaf can just look to see if there's any rouge hyuuga out there or any other known ninja with a stole eye and if there isn't that narrows things down.

Suddenly you've narrowed it down from "Who the hell is this guy, he could literally be anyone" to "he's either a rouge hyuuga, a survivor of the uchiha clan, or some dude with special eyes either way lets change our approach assuming that he could be any of the three".
