WebJul 20, 2024 · However, different from digital watermarking, which embeds watermarks into multimedia content, we needed to design a new method to embed watermarks into DNN models. In our paper, we describe an approach to infuse watermarks into DNN models, and design a remote verification mechanism to determine the ownership of DNN models by … WebSep 1, 2016 · Basically, when it is applied to images, watermarking modifies or modulates the image pixels’ gray level values in an imperceptible way in order to encode or insert a message (i.e. the watermark). The message can be a set of security attributes [3] that will protect the image while it is accessed.
