Our goal is to enable the aggregation and utilization of data for medical research and AI training through privacy-enhancing technologies (PETs) like Zero-Knowledge Proofs (ZKPs), while ensuring patient control and consent via Verifiable Credentials (VCs).<\/p>\n\n<p>Scope and Problem Statement<\/p>\n\n<p>The development of robust medical AI is hampered by siloed, non-standardized, and sensitive health data. Current data formats are incompatible across institutions, and privacy regulations prevent the sharing of raw data, creating a significant barrier to collaborative research. This group will address this by creating schemas that transform health data into standardized, verifiable, and privacy-preserving assets.<\/p>\n\n<p>Key Deliverables<\/p>\n\n<ul>\n<li>A core set of modular, extensible Verifiable Credential schemas for common medical data types (e.g., lab results, imaging reports, prescriptions, diagnoses)<\/li>\n<li>Best practice guidelines for issuing these VCs from trusted sources (e.g., hospitals, clinics)<\/li>\n<li>Specifications for generating Zero-Knowledge Proofs from these VCs to enable privacy-preserving queries and analytics<\/li>\n<li>Use cases and implementation patterns for federated learning and AI model training using the proposed schemas and ZKP protocols<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-dots\" \/>\n\n\n\n<p>In order to <a href=\"\/community\/uhds\/join\">join the group<\/a>, you will need\n    a <a href=\"\/account\/request\/\">W3C account<\/a>.
