Privacy & Security Infrastructure   |   Core Project   |   National

A national initiative to build a privacy-preserving data processing and exchange framework for sensitive data within India’s Digital Public Infrastructure.

Overview

P3DX strengthens privacy and security for sensitive data within India’s DPI. CDPG is the designated executing and responsible entity, leading platform development, applied research in privacy- and security-enhancing technologies, and real-world use-case deployment.

Objectives

  • Build a national framework for privacy-preserving processing and exchange of sensitive data.
  • Advance applied research in privacy- and security-enhancing technologies (PETs).
  • Deploy real-world use cases demonstrating secure handling of sensitive data within DPI.
  • Foster an open-source consortium and international collaboration for sustainability.

Key Features

  • Privacy-enhancing technologies including secure multi-party computation (SMPC), homomorphic encryption, secure enclaves, and federated learning.
  • Framework designed specifically for sensitive data within India's Digital Public Infrastructure.
  • Open-source consortium model to ensure long-term sustainability and adoption.
  • International engagement to align with global best practice in privacy-preserving computation.

Use Cases

Secure Multi-Party Computation research (e.g., MOTION2NX-based secure image inference, ‘Ruffle’ 3-party shuffle protocols) demonstrating joint computation without exposing raw data.

Cross-department analytics on sensitive citizen data (health, welfare, financial) without centralising raw records.

Prototype deployments applying PETs to real DPI use cases as a proof point for wider national rollout.

Data / Datasets Available

No public dataset, P3DX is infrastructure/technology (PETs and secure-computation frameworks) rather than a data catalogue; it is designed to let sensitive datasets already held by government bodies be jointly analysed without being exposed or centralised.

Our Role

CDPG is the designated executing and responsible entity for P3DX, leading platform development, applied PET research, and deployment of real-world use cases.

Impact

National-level initiative under active development, positioned as a foundational privacy layer for India’s broader DPI ecosystem.
