Disentangled Information Bottleneck guided Privacy-Protective JSCC for Image Transmission. (arXiv:2309.10263v1 [cs.CR])

Joint source and channel coding (JSCC) has attracted increasing attention due
to its robustness and high efficiency. However, JSCC is vulnerable to privacy
leakage due to the high relevance between the source image and channel input.
In this paper, we propose a disentangled information bottleneck guided
privacy-protective JSCC (DIB-PPJSCC) for image transmission, which aims at
protecting private information as well as achieving superior communication
performance at the legitimate receiver. In particular, we propose a DIB
objective to disentangle private and …
