Google Research has developed a novel method for generating differentially private synthetic photo albums. This approach utilizes an intermediate text representation and a hierarchical generation process to ensure data privacy while maintaining thematic coherence and character consistency across multiple images. The system first translates original photo albums into structured text, then fine-tunes large language models to generate album summaries and individual photo captions. Finally, these text representations are converted back into synthetic images using a text-to-image model, offering a more efficient and robust way to create private, representative datasets for complex, multi-modal applications.
