Differentially Private Synthetic Data Generation Using Context-Aware GANs
Unlocking Secure Data Sharing with Context-Aware GANs
Revolutionizing synthetic data generation for privacy-sensitive domains like healthcare, finance, and security.
Executive Impact & Key Metrics
This paper introduces ContextGAN, a novel framework for differentially private synthetic data generation that integrates domain-specific context through a constraint matrix. Addressing the limitations of traditional GANs, ContextGAN ensures generated data adheres to explicit statistical properties and implicit domain rules, crucial for realism and utility in sensitive fields. With strong privacy guarantees via a differentially private discriminator, ContextGAN excels in generating high-quality, privacy-preserving synthetic data, outperforming state-of-the-art models in fidelity, utility, and resilience against privacy attacks across healthcare, security, and finance datasets.

Data anonymization, secure cryptographic methods, and distributed model release each have limitations. Synthetic data generation offers a promising alternative by creating new datasets that maintain statistical similarities to real data but lack direct individual associations. Differential privacy is crucial for safe collaboration. ContextGAN improves upon existing methods by ensuring privacy while maintaining data utility.
GANs have shown promise in generating synthetic data. However, they struggle to scale effectively in domains where domain-specific context plays a critical role. ContextGAN addresses this by integrating domain-specific contextual rules through a constraint matrix and ensuring differential privacy during training through techniques like gradient clipping and noise addition.
GANs often possess a restricted understanding of network attributes. Knowledge guidance is essential in conveying explicit constraints to the generative model. Knowledge Graphs (KGs) serve as a versatile graph-structured data model for knowledge representation and reasoning. ContextGAN integrates domain-specific knowledge to ensure realism and adherence to protocol necessary for meaningful and accurate synthetic data generation.

Healthcare Application: Drug Interaction Prevention
In healthcare, ContextGAN was successfully applied to generate synthetic patient records that adhere to prescription guidelines. This prevents medically inappropriate or unrealistic patient profiles by ensuring certain drug combinations are avoided for patients with specific conditions, even when these rules are not explicitly present in the original training data. This demonstrates ContextGAN's ability to maintain realism and utility in highly sensitive medical research without violating privacy laws. ContextGAN prevents harmful drug interactions in synthetic patient data.
