When you take a photo on your smartphone, it will also store information in the photo about when and where the photo was taken. This is called EXIF (Exchangeable image file format) data. It is then possible to determine the location of where the photo was taken, and this can potentially compromise client confidentiality. The solution to this is to turn off “location services” for your camera (on the iPhone go to “Settings” – “Location Services” – and then scroll down to “Camera” and turn it off).
If you are unsure if your photo has location data stored on it, you can use the app NoIMGdata to checkfor location data and remove the location data.
2. Your photo will appear in the bottom left corner, and next to the photo, it will say if there is “No Location Data”, or in this example it says”Location Data found”. To see what data is stored, tap on “View EXIF”
3. Scroll through the metadata, and you will find the Longitude and Latitude information where the photo was taken. A map on the right side will show where the photo was taken. Tap on “Done” to get back to the “clear metadata from images” page.
5. The app now shows that there is “No Location Data”, and it has saved the photo to your camera roll. After doing this, you can delete the original photo so that there is no personal information regarding location stored in your iPhone.
