Tell HN: iPhone mirroring on iOS/macOS breaks screenshot protection on all apps

10 pointsby mintone8 months ago
I appreciate that this is somewhat obvious on reflection, but I am surprised that no one is talking about it given that it breaks security/privacy flows for major apps (obviously a photo of the screen was always a risk)

It makes apps like Snapchat, Telegram and other apps that detect and prevent &#x2F; block screenshots useless now.<p>I heard that Apple knows about this issue (via Feedback Assistant) and their development team said they won’t fix it.

This is always a very interesting topic for me. On one hand, I would like apps to be able to enforce rules like “no screenshots” or at a minimum “screenshot detection”. On the other hand, I want my phone to do what I ask you to do and not be forced to follow arbitrary rules.<p>Example: I don’t want someone to screenshot my Snapchat message but I don’t want my bank to prevent me from screenshotting the app because of “security” (aka security theater).<p>I don’t know how you make those two concepts work together.<p>One random thought that I just had is that when an app uses DRM it just show a black screen when you screenshot. I wonder if could implement that for things like Snapchat to get the same protections.

Hi, which app did you see this on? WhatsApp is a big one that comes to mind.

Google has had mirroring in the form of Casting for like a decade.

Couldn&#x27;t you already do that with a USB-C HDMI cable? Stream the screen and record it.

screenshot protection is a lie
