How to know if user has entered invalid $routeparams

Question

I can access query url params using

$scope.$on('$routeUpdate', function () {    
    var id = $routeParams.id
   //check if user has entered any params other than "id".
   //if yes do someting
});

I need to prevent user from entering params other than "id".

eg:

example.com/?id="something" is accepted

example.com/?junk="something" should be rejected.

Is there any way for this?

Elaborating what the guys are saying the comments you could do something like the following where you are initialising your app (in the run function or in a root controller) or within your routeUpdate listener:

if($location.search.id){
    $location.search({id:$location.search.id}));
} else {
    $location.search({});
}

Obviously you'll need to inject the $location into the DI (add it as a param in that function scope - the scope your listener is in in your question).
