"In another Orwellian measure, Pyongyang phones' government-created operating system takes screenshots of the device at random intervals, the two defectors say-a surveillance feature designed to instill a sense that the user is always being monitored. The images from those screenshots are then kept in an inaccessible portion of the phone's storage, where they can't be viewed or deleted."

Hypothetical: What if the images were instead kept inside an Apple "Secure Enclave". The Secure Enclave is equipped with a dedicated secure nonvolatile storage device. How could the owner of the device access and delete them.
