  • Patent number: 10216945
    Abstract: Some embodiments on the invention are directed to displaying and viewing secure digital contents on touch screen displays. In one embodiment, a digital content such as image, text, or video is displayed on a touch screen display. An obscured layer that prevents viewing of the content protects the digital content. The obscured layer can be temporarily removed by a finger stroke in any direction on the touch screen display. As the finger is moved on the screen the area underneath the stroke is cleared and the content is revealed. The cleared area is then obscured again after a predetermined amount of time. This novel method prevents saving the digital content by taking a screenshot.
