Sovereign AI for Indian Public Sector Banking

A PII Data Boundary Architecture for Hybrid Cloud Agentic AI

Public Sector Banks must adopt agentic AI at scale while production PII stays inside Indian jurisdiction and under the bank's effective control. This reference architecture keeps applications, customer data and the PII boundary entirely on-premises, using cloud GPU inference only on de-identified token payloads — so original PII never leaves the bank.

  • Aligned to DPDP Act 2023, the RBI FREE-AI Framework, UIDAI Aadhaar masking and CERT-In directions
  • Four technical deep-dives: egress DLP rule set, IndicBERT fine-tuning, Open Policy Agent re-identification policies, Finacle-grade tokenisation
  • Federated data governance across on-prem and cloud, plus AI governance for cloud-hosted models
  • Comparative analysis against SageMaker, Bedrock, Azure OpenAI and Vertex AI, with a phased roadmap

India's National RRB Stack

Tantor as the digital nerve centre and intelligence hub for regional rural banks

Regional Rural Banks serve over 40 crore customers across 22,000+ branches, and consolidation under “One State, One RRB” has left them managing roughly 31.33 crore deposit and 3.03 crore loan accounts on fragmented, pre-merger systems. This paper sets out a unified intelligence layer that connects those systems rather than replacing them.

  • The data foundation: federating CBS, LOS, KYC/CKYC, SHG/JLG, credit bureau and weather & agri sources into one model
  • The intelligence layer: specialised AI apps for credit decisioning, early NPA prediction and instant digital onboarding
  • Built for supervisory transparency — reporting that stands up to NABARD and sponsor-bank scrutiny
  • Impact and expected outcomes, with a glossary for non-technical readers
