A signature is calculated automatically based on snapshots of the content item that are captured at the display device, and this signature is transmitted to a remote server that compares this signature with a similar signature calculated based on a scheduled content item expected to be displayed on the digital screen and, if the signature of the displayed content item corresponds to the signature of the scheduled content item, a token authenticating the displayed content item is generated.
