New framework enables differentially private synthesis of paired table-image data

Researchers have developed DP-TabImage, a new framework for synthesizing paired tabular and image data while maintaining differential privacy. This approach addresses the challenge of preserving the dependence between modalities when applying privacy techniques, which often favor different mechanisms for each data type. DP-TabImage utilizes a private Probabilistic Graphical Model for tabular data and a table-conditioned diffusion model trained with DP-SGD for image generation, achieving a balance between tabular fidelity, image fidelity, and cross-modal alignment.
