Patent ID: 8755598

Claim:
A method comprising: capturing a video stream comprising embedded data; at a segmenter, segmenting the video stream into a plurality of video frames comprised therein; at a color mass locator, locating a color mass, denoted C′, for each color element of every individual video frame of the plurality of video frames by summing color value coordinates for a given color element comprised in the individual video frame; at a color mass locator, locating a color mass, denoted C, for each color element of a corresponding individual video frame, the corresponding individual video frame corresponding a video frame which does not comprise embedded data; at a processor, subtracting C from C′; and at a deriver, deriving, from a result of the subtraction, a value of a first coordinate and a second coordinate, the first coordinate and the second coordinate comprising coordinates of a vector, the vector corresponding to a string of bits, the string of bits comprising information embedded in the individual video frame.
