I have a Truecrypted, airgapped (no internet connectivity at all) laptop that I use as a completely secure computer for sensitive files.
I want to add images from my iPhone (I know), camera or other device. What is the safest way to do this? I know safety will have to be compromised in some way, but I need to best. Here's my thoughts:
- USB: On a normal computer, transfer the files from camera to usb. Then from usb to airgapped laptop. Problem: malware could transfer from normal computer to airgapped laptop via USB.
- Upload from iPhone to internet, connect directly from airgapped laptop temporarily before returning to internetless state. Problem: internet access is dangerous.
- Upload from camera to Tails booted from any PC. Transfer to formatted USB, then transfer to airgapped laptop. Problem: very slow, inconvenient and Tails may have driver problems with certain devices.
Is there an obvious solution I am missing?
