Are you talking about data, or the map? Google want the map to be
accessible by as many people as possible as easily as possible, so
their logo and any advertising they choose to add gets the widest
possible exposure. They don't care how you protect your data just as
long as everyone can get at the map.

I reckon (although there are those who disagree) that it should be
possible -- say -- to set a cookie with a login which controls which
data is displayed on the map. No login: map but no data; with a login,
exactly the same url will show the map with data.
