When Privacy Isn't Synthetic: Hidden Data Leakage in Generative AI Models
NegativeArtificial Intelligence
- Generative AI models, often used to create synthetic data for privacy preservation, have been found to leak sensitive information from their training datasets due to structural overlaps in data. A new black-box membership inference attack can exploit this vulnerability without needing access to the model's internals, allowing attackers to infer membership or reconstruct records from synthetic samples.
- This development raises significant concerns for sectors like healthcare and finance, where sensitive data is frequently handled. The ability of adversaries to extract information from synthetic data undermines the intended privacy protections and could lead to serious breaches of confidentiality.
- The findings highlight a critical tension in the use of generative AI for data synthesis, as the technology is simultaneously advancing in areas like bias mitigation and privacy-aware data generation. Ongoing research is needed to address these vulnerabilities while ensuring that synthetic data can be safely utilized across various applications, including clinical research and financial modeling.
