New TADP framework anonymizes videos while preserving facial expressions

Researchers have developed TADP, a novel framework for anonymizing videos while preserving facial expressions. This dual-branch system separates identity and expression representations, applying temporally adaptive differential privacy to each. The method uses Gaussian mechanisms and Rényi Differential Privacy to ensure clip-level privacy guarantees, with experiments showing reduced identity leakage and maintained utility for facial expression recognition compared to existing methods.
