California Attorney General Kamala D. Harris this week issued a consumer alert on location services used by mobile applications (apps).
With a tap on a smartphone or tablet, users can get a list of nearby restaurants, directions to a friend’s home or a local weather forecast. Location services on a device make a variety of convenient apps work. Location services take an individual’s geographic information from satellites (GPS), WiFi and cell-tower networks. What users may not realize, according to Harris, is that some apps can access a user’s location all the time, even when they’re not using them. Their location might be “always on.”
“Broadcasting your location can sometimes expose you and your family to risk of theft or physical harm,” Harris said. “For instance, you may be unknowingly revealing your location if your phone is ‘geo-tagging’ your photos. When you take a photo, the location where it was taken may be inserted into the image file, along with the date/time stamp. If you post the photo online, you are revealing your location at a point in time. Sharing a ‘selfie’ without disabling geo-tagging can be dangerous, especially for victims of stalking or domestic abuse.”
By adjusting the settings on a mobile device, the user can control location services to protect their privacy on today’s “always on” frontier, Harris said.
Android phones and devices
Go to Settings, then Location and uncheck the boxes. When an app asks for access to your location, you can chose to grant it or not.
To disable geo-tagging of photos, open the camera and then click on the gear icon and set location to “No.” You may have to click the gear icon on several screen layers.
You can also choose how accurate you want your location reporting to be, whether it is determined based on GPS plus WiFi and cellular networks or just one or the other. The higher degree of accuracy uses more of your battery, so protecting your privacy will protect your battery life too.
iPhones and iPads
(iOS 6 and later)
Go to Settings, then Privacy, then Location Services. You can turn it off. Or you can choose which functions and apps to give access to your location.
To disable geo-tagging of photos, deny location access to the camera, in Location Services.
You may get notifications from apps asking to use your location in the background. For privacy, select “Don’t Allow.”
