Aadhaar Data Vault as a Service

Data protection and privacy have always been a concern for individuals when they're involved in the various electronic processes happening within the government structure. The existence of certain data always poses risks to the citizens' privacy, and most importantly, information that contains personal identity numbers. The Aadhaar number is one such identity for which its secure management while availing various Government services has always been a concern. 

Therefore, UIDAI mandates the secure storage of residents' Aadhaar numbers in a separate repository known as ‘Aadhaar Data Vault’. All government departments offering citizen services and using the Aadhaar number in their application workflows are required to use the Aadhaar Data Vault for secure management of Aadhaar numbers and related data.

By establishing Aadhaar Data Vault, the UIDAI aims to enhance the security and privacy of residents' Aadhaar information, thereby reinforcing the overall integrity and trustworthiness of the Aadhaar ecosystem.
