captures a further watermark and extracts a payload comprising a correct answer, a ratiovalue and a token value. If the correct answer is equal to the answer received from theuser, the remote device generates a comparison value, compares the comparison valueand a ratio value extracted from the payload and, if the comparison between thecomparison value and the ratio value indicates that remote device has been selected,displays a message intended to a user. The remote device can further generate a valuefrom at least the token value and display this value as proof of being selected.
