Unauthorized viewer detection system and method

A method of detecting and responding to an intruding camera, comprising:

• displaying content on an electronic media display device having a screen;
• obtaining information from a sensor;
• analyzing the information to determine a presence of a camera and whether the camera can resolve any displayed content, wherein determining whether the camera can resolve any displayed content is based on a two dimensional viewing angle of the camera relative to an axis orthogonal to the screen, the two dimensional viewing angle comprising an azimuth component and an elevation component, and wherein determining that the camera can resolve any displayed content comprises determining that both the azimuth component and the elevation component are within maximum azimuth and elevation angle thresholds;
• and
• editing the displayed content in response to the camera being able to resolve the displayed content so that the camera can no longer resolve the displayed content.

A non-transitory computer-readable medium having instructions stored thereon for execution by a processing circuit, the instructions comprising:

• instructions for interfacing with an electronic media display device having a screen for visual content;
• instructions for obtaining information from a sensor, wherein the information corresponds to the environment around the electronic media display device;
• instructions for analyzing the information to determine a presence of a camera and whether the camera can resolve any displayed content, wherein determining whether the camera can resolve any displayed content is based on a two dimensional viewing angle of the camera relative to an axis orthogonal to the screen, the two dimensional viewing angle comprising an azimuth component and an elevation component, and wherein determining that the camera can resolve any displayed content comprises determining that both the azimuth component and the elevation component are within maximum azimuth and elevation angle thresholds;
• and
• instructions for editing the displayed content in response to the camera being able to resolve the displayed content so that the camera can no longer resolve the displayed content.
