Q. Examine the interoperability and consent-based architecture of ABDM. How does it address concerns of data privacy while enabling seamless health data exchange? (15 marks, 250 words)

The Ayushman Bharat Digital Mission (ABDM), launched nationwide on 27 September 2021 under the National Health Authority, recently crossed 100 crore ABHA-linked health records [1]. Its architecture seeks to reconcile two competing goals: frictionless health-data exchange and citizen privacy.

Interoperability architecture - Built on a federated (non-centralised) model — records stay with the generating hospital/lab and are exchanged on demand, not pooled in one repository [1]. - The ABHA (14-digit unique health ID) acts as the linking key across providers, ensuring portability of records [3]. - Common Health Information Exchange & standards let 450+ public and private health-tech solutions interoperate seamlessly [1].

Consent-based privacy safeguards - A Consent Manager governs every data pull — sharing occurs only after explicit, purpose-specific patient consent [1]. - Minimisation: since data is not centrally stored, breach of a single node cannot expose the whole ecosystem [1]. - The ABHA is distinct from Aadhaar, limiting profiling risk [3].

Residual concerns - Uneven state saturation risks a digital divide for rural/low-literacy users [1]. - Consent fatigue and enforcement of privacy under the Digital Personal Data Protection Act, 2023 remain untested at scale.

By decoupling storage from access and anchoring exchange in verifiable consent, ABDM offers a privacy-by-design template mirroring India's Digital Public Infrastructure success. Strengthening grievance redress and data-fiduciary accountability under DPDP will ensure this ecosystem advances the constitutional right to privacy alongside universal health access.
