iOS apps can read metadata revealing users' location histories

Charles 9 Silver badge

"The OS could allow apps access to temporary copies of the files that have the EXIF information blanked, unless you choose to allow the app "photo metadata" permissions - that's what you'd use for something backing up photos or copying them off the device."

How would it know to do that, especially if the app accesses the photos as files rather than as images? If you say it's the OS's responsibility to look for things like magic numbers, that defeats the minimalist approach and can introduce possible exploits by doing a Confused Deputy.
