摘要:

在多媒体数据分析领域,图像数据集的大量使用加剧了对此类数据隐私保护的担忧。当前研究主要聚焦于数据共享阶段或已训练机器学习模型发布阶段的隐私保护。本研究开创了一个综合隐私保护框架,能够在数据共享和模型发布过程中同时保护图像数据隐私。我们提出了一种交互式图像隐私保护框架,利用生成式机器学习模型在属性层面修改图像信息,并采用机器遗忘算法对模型参数进行隐私保护。该用户交互式框架允许根据用户对生成图像的反馈调整隐私保护强度,在最大化隐私保护与维持模型性能之间取得平衡。在该框架内,我们实例化了两个模块:一个用于保护图像属性信息的差分隐私扩散模型,以及一个用于在修订后的图像数据集上高效更新已训练模型的特征遗忘算法。我们的方法在面部数据集上的多种属性分类任务中表现出优于现有方法的性能。

英文摘要:

In the realm of multimedia data analysis, the extensive use of image datasets has escalated concerns over privacy protection within such data. Current research predominantly focuses on privacy protection either in data sharing or upon the release of trained machine learning models. Our study pioneers a comprehensive privacy protection framework that safeguards image data privacy concurrently during data sharing and model publication. We propose an interactive image privacy protection framework that utilizes generative machine learning models to modify image information at the attribute level and employs machine unlearning algorithms for the privacy preservation of model parameters. This user-interactive framework allows for adjustments in privacy protection intensity based on user feedback on generated images, striking a balance between maximal privacy safeguarding and maintaining model performance. Within this framework, we instantiate two modules: a differential privacy diffusion model for protecting attribute information in images and a feature unlearning algorithm for efficient updates of the trained model on the revised image dataset. Our approach demonstrated superiority over existing methods on facial datasets across various attribute classifications.
