How do I identify if a screenshot is taking place on the site.
For example, when Netflix is watching a movie or series and trying to get a print, it causes the print result to go completely black.
How can she identify the act of taking a print? Is it with javascript?
Short answer:
There is no reliable way to detect screenshot.
Long answer:
There are several ways the operating environment can capture what is being displayed; This is true for both Windows and Linux and MacOS. Not all ways generate disruptions, and the vast majority of these are not monitored by browsers .
What you see when you take a screenshot while watching Netflix is the result of another technology: DRM (digital rights management). A screen capture function includes only content that is not marked as safe.
An integration between the streaming service (which adds DRM to content), the browser that displays the stream (which marks areas of the screen that are displaying content with DRM), and the operating environment (which identifies secure displays that have encryption technology between the video source and the device) allows you to view the content but prevents copies by the OS by non-party processes of the rights management chain.
