Watermarking

We conduct a brief yet comprehensive review of existing literature and outline three meta-architectures. Based on this, we summarize specific strategies for various applications of deep hiding, including steganography, light field messaging and watermarking. Finally, further insight into deep hiding is provided through incorporating the perspective of adversarial attack.

We propose a novel universal deep hiding (UDH) meta-architecture to disentangle the encoding of a secret image from the cover image. Our analysis demonstrates that the success of deep steganography can be attributed to a frequency discrepancy between the cover image and the encoded secret image. Exploiting UDHs universal property, we extend UDH for universal watermarking and light field messaging.
