- Abstract: We propose a watermarking method for protecting the Intellectual Property
(IP) of Generative Adversarial Networks (GANs). The aim is to watermark the GAN
model so that any image generated by the GAN contains an invisible watermark
(signature), whose presence inside the image can be checked at a later stage
for ownership verification. To achieve this goal, a pre-trained CNN
watermarking decoding block is inserted at the output of the generator. The
generator loss is then modified by including a watermark loss term, to ensure
that the prescribed watermark can be extracted from the generated images. The
watermark is embedded via fine-tuning, with reduced time complexity. Results
show that our method can effectively embed an invisible watermark inside the
generated images. Moreover, our method is a general one and can work with
different GAN architectures, different tasks, and different resolutions of the
output image. We also demonstrate the good robustness performance of the
embedded watermark against several post-processing, among them, JPEG
compression, noise addition, blurring, and color transformations.
