The Synthetic Data Spectrum: Where Does Anonymisation Start and Privacy-preserving end?
summary
Panel argues synthetic data is not magic: industry uses it mainly for AI training and product development (banks, insurers, telcos, public sector), but identifiability requires empirical testing like red‑teaming and adversarial checks (membership and attribute inference attacks). Formal tools such as differential privacy exist but are hard to apply without weakening utility; benchmarking, regulator sandboxes, and independent audits (IE group ~70 experts) are emerging practices. Generating web‑scale corpora for LLMs remains impractical today.
