Abstract:
1. A method for detecting an analog reconverted video file, comprising: receiving location data recording the location of the digital token and the original configuration from a data source, wherein the original configuration specifies a characteristic color noise component and the location data specifies corresponding regions of at least two contiguous I-frames of video content in the video file; measuring a color noise component of the digital token; comparing the color noise component of the digital token to the characteristic color noise component specified by the original configuration; transmitting a signal indicating that the video file is an analog reconverted file, if the color noise component is greater than the characteristic noise component of original configuration; and transmitting a signal indicating that the video file is not an analog reconverted file, if the color noise component matches the characteristic noise component of the original configuration.
