I need to prevent screen capture by users of my app, for security reasons. The contents I display are confidential and should not be copied onto the device.
How prevent screen capture in an iOS app?
Unfortunately you really can't. There is a notification that ios send to the app as the screenshots is already taken.
I have searched this topic also for my app and i came across a method that i have not yet tested but can be funny,
The method was to mask the image for each frame.
Doing this, at 60fps, it means that you can mask each frame with occluding images and the human eye should not catch this... but the screenshot will take a masked image.
As already said, not yet tested but could work.
pls. reference the MLT links below.
Just remember that there is nothing your app can do to prevent a user pointing a camera at the device and taking a picture of any screen.
Rule is if you don't want confidential info out in the wild, don't put it there.
Has this topic evolved and if Not can you show me how I can blur the image or distort the image? Like referenced Plz......?
