: This research involved only simulation-based analyses using synthetic data and did not involve any human participants, real clinical records, or personal identifiers. All Aadhaar-linked and DID-based entities were artificially generated to mimic structural characteristics of digital identities without referencing or linking to any real individuals. To ensure ethical compliance and privacy-by-design, all experiments followed NDHM, DEPA, and FHIR privacy principles, including: (1) pseudonymization of all identity data; (2) cryptographic separation between consent artifacts and analytical data; and (3) compliance with purpose limitation and data minimization guidelines. Any future real-world pilot deployment will undergo independent Institutional Ethics Committee (IEC) review and data protection impact assessment (DPIA) prior to involving live systems or actual health identifiers.
