Abstract
The present invention relates to a robust hologram watermarking system based on artificial intelligence, in which an attack simulation is added before an operation of a hologram resolution adjustment network so that training is performed to exhibit a feature that is more robust against an attack. A hologram is watermarked by using deep learning, and training is performed by adding an attack simulation in a training process and adding quality of a distance between a real part and an imaginary part in a complex space to a loss function, so that watermarking is more robust against an attack.
