摘要:

我们根据自监督方法重新审视基于预训练深度网络的水印技术。我们提出了一种方法来嵌入标记和二进制消息到他们的潜在空间,利用数据增强标记时。我们的方法可以在任何分辨率下操作,并创建对各种变换(旋转,裁剪,JPEG,对比度等)鲁棒的水印。它显著优于以前的零比特方法,并且其在多比特水印上的性能与最先进的端到端训练的编码器-解码器架构相当。代码可在github.com/facebookresearch/ssl_watermarking上获得

英文摘要:

We revisit watermarking techniques based on pre-trained deep networks, in the light of self-supervised approaches. We present a way to embed both marks and binary messages into their latent spaces, leveraging data augmentation at marking time. Our method can operate at any resolution and creates watermarks robust to a broad range of transformations (rotations, crops, JPEG, contrast, etc). It significantly outperforms the previous zero-bit methods, and its performance on multi-bit watermarking is on par with state-of-the-art encoder-decoder architectures trained end-to-end for watermarking. The code is available at github.com/facebookresearch/ssl_watermarking
