Abstract

A screen capture prevention method includes serving a single-color, DRM-protected video clip for display as a background for a document on a web browser. The document is processed to render its background color as transparent. Content of the document is viewable over the contrasting video clip background. When a screen capture event is detected, the video clip is changed to a same color as the content of the processed document, rendering the content indistinguishable from the background while the screen capture event is active.
