Abstract
Recent Customized Portrait Generation (CPG) methods, taking a facial image and a textual prompt as inputs, have attracted substantial attention. Although these methods generate high-fidelity portraits, they fail to prevent the generated portraits from being tracked and misused by malicious face recognition systems. To address this, this paper proposes a Customized Portrait Generation framework with facial Adversarial attacks (Adv-CPG). Specifically, to achieve facial privacy protection, we devise a lightweight local ID encryptor and an encryption enhancer. They implement progressive double-layer encryption protection by directly injecting the target identity and adding additional identity guidance, respectively. Furthermore, to accomplish fine-grained and personalized portrait generation, we develop a multi-modal image customizer capable of generating controlled fine-grained facial features. To the best of our knowledge, Adv-CPG is the first study that introduces facial adversarial attacks into CPG. Extensive experiments demonstrate the superiority of Adv-CPG, e.g., the average attack success rate of the proposed Adv-CPG is 28.1% and 2.86% higher compared to the SOTA noise-based attack methods and unconstrained attack methods, respectively.

最近定制化肖像生成(CPG)方法,通过面部图像和文本提示作为输入,引起了广泛关注。尽管这些方法能够生成高保真的面部画像,但它们无法防止生成的画像被恶意人脸识别系统追踪并滥用。为了解决这个问题,本文提出了一种结合了面部对抗攻击的定制化肖像生成框架(Adv-CPG)。为了实现面部隐私保护,我们设计了一个轻量级的身份加密器和一个增强器。身份加密器通过直接注入目标身份信息来实施渐进式的双层加密保护;而增强器则是通过添加额外的身份指导来加强这一过程。 此外,为了完成精细且个性化的肖像生成,我们开发了一种多模态图像定制器,能够生成受控的细粒度面部特征。据我们所知,Adv-CPG是第一个将面部对抗攻击引入到CPG中的研究工作。广泛的实验展示了Adv-CPG的优势,例如:提出的Adv-CPG方法平均攻击成功率达到了28.1%,比最先进的基于噪声的方法高出2.86%。 翻译成中文如下: 最近定制化肖像生成(Customized Portrait Generation, CPG)方法因其能够利用面部图像和文本提示作为输入而吸引了大量关注。尽管这些方法可以生成高保真的面部画像,但它们无法防止生成的画像被恶意的人脸识别系统追踪并滥用。为了解决这个问题,本文提出了一种结合了面部对抗攻击(Adversarial attacks, Adv)的定制化肖像生成框架(Adv-CPG)。为了实现面部隐私保护,我们设计了一个轻量级的身份加密器和一个增强器。身份加密器通过直接注入目标身份信息来实施渐进式的双层加密保护;而增强器则是通过添加额外的身份指导来加强这一过程。 此外,为了完成精细且个性化的肖像生成,我们开发了一种多模态图像定制器,能够生成受控的细粒度面部特征。据我们所知,Adv-CPG是第一个将面部对抗攻击引入到CPG中的研究工作。广泛的实验展示了Adv-CPG的优势,例如:提出的Adv-CPG方法平均攻击成功率达到了28.1%,比最先进的基于噪声的方法高出2.86%。
