This article proposes an innovative watermarking technique based on Syntetic Holograms (SH), called “Synthetic Holographic Watermarking (SHW)”. The target image has been superposed with the synthetic representation of the mark Hologram.The mark can be retrieved using the Fourier Transform (in the FFT implementation).Correlation techniques and statistic thresholds can be used for evaluating possible marked image manipulations.
