Steganography for Neural Radiance Fields by Backdooring. (arXiv:2309.10503v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
The utilization of implicit representation for visual data (such as images,
videos, and 3D models) has recently gained significant attention in computer
vision research. In this letter, we propose a novel model steganography scheme
with implicit neural representation. The message sender leverages Neural
Radiance Fields (NeRF) and its viewpoint synthesis capabilities by introducing
a viewpoint as a key. The NeRF model generates a secret viewpoint image, which
serves as a backdoor. Subsequently, we train a message extractor using
overfitting to …
