摘要
A phase space encoded watermark is applied to an image to guard against counterfeiting and/or unauthorized copying. The watermark is formed of wavepackets. An authentication message is encoded in the wavepackets by variations in one or both of the intensities of the wavepackets and the phases of the wavepackets.
