本文提出VeriFi框架,结合版权保护、像素级篡改定位和高保真面部内容恢复,通过紧凑语义潜在水印和AIGC攻击模拟器提升水印鲁棒性和恢复质量。

摘要:

AIGC驱动的面部操纵和深度伪造的普及对媒体来源、完整性和版权保护构成严重威胁。现有多功能水印系统通常依赖嵌入显式定位载荷,导致保真度与功能性的权衡:较大的定位信号会降视觉质量并减少在强生成编辑下的解码鲁棒性。此外,现有方法很少支持内容恢复,限制了在原始证据必须重建时的取证价值。为解决这些挑战,我们提出了VeriFi,一个统一版权保护、像素级操纵定位和高保真面部内容恢复的水印框架。VeriFi有三个关键贡献:(1)嵌入紧凑的语义潜在水印作为内容保持先验,即使在严重篡改后也能实现忠实恢复;(2)通过相关图像特征与解码来源信号实现细粒度定位,而无需嵌入定位特定的伪影;(3)引入AIGC攻击模拟器,结合潜在空间混合与无缝融合,提高对现实深度伪造管道的鲁棒性。在CelebA-HQ和FFHQ上的广泛实验表明,VeriFi在水印鲁棒性、定位准确性和恢复质量上均优于强基线,为深度伪造取证提供实用且可验证的防御。

英文摘要:

The proliferation of AIGC-driven face manipulation and deepfakes poses severe threats to media provenance, integrity, and copyright protection. Existing versatile watermarking systems typically rely on embedding explicit localization payloads, which introduces a fidelity--functionality trade-off: larger localization signals degrade visual quality and often reduce decoding robustness under strong generative edits. Moreover, these methods rarely support content recovery, limiting their forensic value when original evidence must be reconstructed. To address these challenges, we present VeriFi, a versatile watermarking framework that unifies copyright protection, pixel-level manipulation localization, and high-fidelity face content recovery. VeriFi makes three key contributions: (1) it embeds a compact semantic latent watermark that serves as a content-preserving prior, enabling faithful restoration even after severe manipulations; (2) it achieves fine-grained localization without dedicated payloads by correlating image features with decoded provenance signals; and (3) it introduces an AIGC attack simulator that combines latent-space mixing with seamless blending to enhance robustness against realistic deepfake pipelines. Extensive experiments on CelebA-HQ and FFHQ demonstrate that VeriFi consistently outperforms state-of-the-art baselines in watermark robustness, localization accuracy, and recovery quality, providing a practical and verifiable defense for deepfake forensics.
