Screenshot blocking: Difference between revisions

'''Screenshot blocking''' prevents the owner of a computing device from capturing screenshots and screen recordings. Some operating systems such as Android OS and iOS let app makers block the device owners from capturing screenshots and screen recordings of certain content.

==How it works==

Blocking screenshots is typically an in-app technology, not something that automatically applies across all apps or devices. Here's how it works, depending on the platform:

On Android, apps can block screenshots using a flag called: WindowManager.LayoutParams.FLAG_SECURE~~{{Citation needed}}~~. When this flag is set on an activity, it prevents the content from being captured in screenshots, screen recordings, and even in the app switcher (recent apps view)~~{{Citation needed}}~~. This is often used by apps like, banking apps, streaming services (e.g., Netflix), and secure messaging apps.

On iOS, iOS does not give developers an official flag like FLAG_SECURE, but they use workarounds, like displaying sensitive content in a UIView with custom rendering, then hiding or blurring it when the app detects screenshot events or apps going into background or app switcher{{Citation needed}}.
