Obito also mentioned that he regularly infiltrated Konoha yet the only one to ever notice was Itachi. So we can clearly state that Obito is able to hide both his identity (see: sasuke) and his chakra (see: itachi), and so Hinata (who has no other chakra color feats or sensory perception feats) would not be able to detect that.
