Visual identifier for images on an electronic display
Abstract:
A system and method for displaying images or video on an electronic display. A unique identifier may be embedded within the frames of images or video and detected by a light sensor. The data from the light sensor is analyzed to determine if the proper image or video was actually shown at the display. Some embodiments analyze the data from the light sensor in real time and may stop displaying the image or video if the data is not in the format of a unique identifier. Using this embodiment, the system can prevent unintended images or video from being shown on the display.
