In a healthcare scenario, patient records could be masked using PHE for sensitive fields like diagnoses, enabling AI model training on encrypted data processed through Substrate's secure runtime.

Secure Medical Data Processing
Differential privacy would protect model outputs, ensuring compliance with regulations like GDPR while maintaining auditability through Substrate's immutable storage, fostering trust in decentralized health research.

Collaborative Research Example
For instance, a researcher developing a predictive model for disease outbreaks could train on masked patient data, with the masking ensuring that individual patient identities remain hidden, and differential privacy protecting the aggregated results shared with other researchers through Substrate's networking layer, thus enabling secure, collaborative health advancements.
