Abstract: This paper proposes a multi-user traceability watermarking neural network approach to model security and copyright certification for deep neural networks (DNN). The watermark is generated by the key driver and embedded invisibly in the output images of the DNN model, hence realizing the intellectual property protection and copyright tracking of DNN model. A codec network is added to the DNN model to embed the watermark, and a two-stream tamper detection network is used as the discriminator. Thus, the problem of residual watermark in the output images of the model is solved, which, reduces the impact on the performance of DNN model and enhances the security. In addition, a two-stage training method is proposed in this paper to distribute different watermarked models to different users. When copyright disputes occur, another residual network can be used to extract the watermark image from the output image. Experiments show that the proposed method is efficient in distributing watermarked models, and is able to trace the source of DNN models embedded with similar watermarked images for multiple users.
