ReFaceX: Donor-Driven Reversible Face Anonymisation with Detached Recovery
Organisations must share facial imagery that remains useful for analysis while protecting identity. Current methods fail to strike this balance: reconstruction-centred encoder-decoder designs tend to blur salient detail, whereas latent edits in pretrained generators often retain or drift identity cues, undermining privacy and utility. ReFaceX provides a practical template for responsible release of facial imagery and a foundation for extensions to video, higher resolutions and stronger recovery guarantees.
Executive Impact
ReFaceX delivers a groundbreaking solution for enterprise privacy compliance and data utility, combining state-of-the-art anonymisation with detached, high-fidelity recovery. Its real-time performance and robustness to real-world distortions offer a compelling advantage for sectors handling sensitive facial data.

Decoupling Privacy and Utility
ReFaceX introduces a novel architectural configuration that explicitly decouples privacy objectives from utility, preventing reconstruction losses from inadvertently preserving identity. This is achieved through donor-guided identity transfer and gradient blocking on the recovery path.

Lowest ArcFace Identity Similarity (Lower is Better)
Compared to RIDDLE (0.012), CIAGAN (0.020), FALCO (0.016), and FIT (0.029), ReFaceX achieves significantly lower identity similarity, indicating stronger anonymisation efficacy across diverse facial recognition models like FaceNet, ArcFace, and AdaFace.
Robust Recovery Fidelity
The system ensures high-fidelity recovery of original images, preserving visual and structural details crucial for downstream analytical tasks. This is achieved through a learned steganographic channel and detached recovery network, maintaining utility without compromising privacy.
| Feature | ReFaceX | Competitor Average |
|---|---|---|
| SSIM (Higher is Better) | 0.9378 (Best) | 0.6682 |
| LPIPS (Lower is Better) | 0.1002 (Best) | 0.1634 |
| PSNR (Higher is Better) | 23.9711 (Best) | 21.2006 |
| Key Advantage | Separates privacy and utility for better trade-off | Often compromises one for the other |
| Recovery Channel | Learned steganographic channel with robustness training | Fragile, less robust to distortions |
| Identity Control | Donor-driven identity transfer with IFF | Unstable or attributes drift |
| Computational Efficiency | Fastest inference (0.005s per image) | Slower, higher latency |
Real-time Computational Efficiency
ReFaceX offers high computational efficiency, achieving real-time inference suitable for throughput-constrained deployments like live video processing. This allows for practical, scalable integration into enterprise systems.
Real-Time Face Anonymisation for Live Video Feeds
Transforming Privacy Protection in High-Throughput Environments
A large surveillance firm requires anonymising faces in live video streams from hundreds of cameras while maintaining detail for event detection. Existing solutions are too slow, causing unacceptable latency and reduced frame rates.
Implementing ReFaceX, the firm achieved an average inference latency of just 0.005 seconds per image (Table 7) on standard GPU hardware. This speed enabled real-time processing of high-definition video, allowing for continuous, privacy-compliant monitoring without performance bottlenecks.
The system successfully anonymised faces with minimal impact on visual utility (SSIM 0.9378), ensuring that non-identity attributes like expression and pose remained detectable for security analysts, while drastically reducing identity leakage. This directly translated to enhanced operational efficiency and compliance with stringent privacy regulations.
