How to convert image to video with DRM (FairPlay)

Question

I want to hide some private content on screenshots. Since Apple provide us only userDidTakeScreenshotNotification, the only way to achieve this is to convert image to video with DRM. According to these thread:

If your application uses FairPlay Streaming (FPS) your video content will automatically not be captured by the iOS 11 screen recording feature or QuickTime Player on macOS. The portion of your application that is playing the content will be blacked out.

I found commercial implementation of these idea in ScreenShieldKit, but it costs money.

The main question: How it's possible to convert image or label to FairPlay Streaming (FPS) video in offline mode?

Look for something called “common encryption”. You will also need a FairPlay server and certificate from Apple. – Ceporah

Ye, but these guys somehow achieved this without any servers, or internet connection at all. They protect content even in offline mode: screenshieldkit. Do you have any ideas how they do this? – Abdominal

@TanyaMarchuk did you ever figure this out? I have a similar requirement. – Babbler

I have a feeling that ScreenShieldKit is using a local KSM (FairPlay server) hosted inside the application. I don't think that is what Apple intended... Btw: From what I remember, as long as you use SAMPLE-AES method for HLS you will also get screenshot blocking. (Not guaranteed... But seems to be the actual behavior). – Fleenor
