US Patent 12118131 Mask including a moveable window for viewing content

Techniques are disclosed for providing protection of sensitive information during the display of the sensitive information on a display. An example methodology implementing the techniques includes, by a computing device, receiving content for display on a display of the computing device and generating a mask for display over the content within the display, the mask including a window so that a portion of the content located within the window is viewable via the display, and content outside the window is not viewable via the display. The method also includes, by the computing device, applying the mask over the content so that the content can be read by moving the window over the content to display individual pieces of the content without display of the content in its entirety.
