Under a new bill dubbed the "GPS Act," law enforcement officials would no longer be able to obtain geolocation data from cellphones and GPS tracking devices without a warrant.

Under the new bill, geolocation data obtained from devices like tablets, smartphones, and GPS trackers would be held to the same standard as a wiretap request; police can go to court, show probable cause, and obtain a warrant if they need access to such information. The current mishmash of court rulings about the legality of warrantless location tracking would be brought into uniformity, though the warrant standard would be relaxed in certain exceptional cases such as emergencies and 911 calls, among other situations.

In addition to laying down a warrant standard for obtaining location data, the law would also apply both to private companies and to individuals. Without a warrant, companies would need consent in order to share a user's geolocation data with anyone else. The bill would also criminalize those who stalk other people by inserting stealth apps on their phones or computers.
