Aadhaar Data Security Overhaul: UIDAI Mandates New 'Digital Vault' for Banks, Fintechs – Big Changes Ahead!

The Unique Identification Authority of India (UIDAI) has mandated that all entities using Aadhaar for authentication or eKYC processes must store this sensitive data in a new, secure system called the Aadhaar Data Vault (ADV). This directive applies to banks, NBFCs, telecom companies, fintech platforms, and government departments.

The ADV is a dedicated, encrypted storage system for critical information like Aadhaar numbers and eKYC XML files, which contain demographic details such as name, date of birth, and address. Its primary purpose is to minimize Aadhaar's digital footprint and ensure strict control over access. Key features include end-to-end encryption of Aadhaar numbers and linked data, comprehensive audit trails to track every access attempt, and ensuring regulatory compliance.

The system works by replacing each Aadhaar number with a unique reference key within an organization's system. The actual Aadhaar number remains encrypted inside the vault and cannot be viewed or extracted without proper authorization, thus preserving user privacy.

For citizens, this means an enhanced layer of protection, as Aadhaar details will be stored in encrypted form only, and local storage of Aadhaar PDFs or eKYC files by entities is prohibited.

Impact: This mandate requires significant operational adjustments and system upgrades for numerous financial institutions and technology providers handling Aadhaar data. It will likely lead to increased compliance costs and stricter data governance. However, the enhanced security measures are expected to substantially reduce the risk of data breaches and identity theft, thereby boosting consumer trust and strengthening the overall digital ecosystem's integrity.
