Use additional factors to notify users of unusual activities and authenticate when accounts may have been compromised.
How can a service effectively provide notice to a user who gave permission once but whose information is accessed repeatedly (perhaps even continuously) over a long period of time? Proactively notify the user after the time of consent that information is being tracked, stored or re-distributed.
Provide an ambient notice (unobtrusive, non-modal) when location is being accessed to increase awareness of ongoing tracking.
