- Abstract: The accelerated use of digital cameras prompts an increasing concern about
privacy and security, particularly in applications such as action recognition.
In this paper, we propose an optimizing framework to provide robust visual
privacy protection along the human action recognition pipeline. Our framework
parameterizes the camera lens to successfully degrade the quality of the videos
to inhibit privacy attributes and protect against adversarial attacks while
maintaining relevant features for activity recognition. We validate our
approach with extensive simulations and hardware experiments.

In this paper, we propose a novel face privacy protection method based on diffusion models, dubbed Diff-Privacy.
Specifically, we train our proposed multi-scale image inversion module (MSI) to obtain a set of SDM format conditional embeddings of the original image.
Based on the conditional embeddings, we design corresponding embedding scheduling strategies and construct different energy functions during the denoising process to achieve anonymization and visual identity information hiding.
