Abstract
Aadhaar is a 12 digit unique identification number, provided to each citizen of India. This includes the biometric data and personal information such as full names, addresses and birthdates. As per the government rule nowadays Aadhaaris linked to the Bank account, PAN Card, Voter ID Card, LPG Connection Card, Ration Card, Mobile number of the citizen of India. In order to ensure the security of Aadhaar, Blockchain technology has the potential to overcome the security and privacy challenges in Aadhaar.Blockchain is a decentralized, cryptographically signed digital ledger where transactions are framed into blocks.The type of information stored in the transactions can be varied (e.g. currency, intellectual property, identity data, location data, etc).Every transaction (and hence block) has a timestamp associated with when it was recorded to the blockchain. Subsequent blocks require the identifier (or hash) of the preceding block, and this is often the link that chains all the blocks together. The distributed consensus nature of the blockchain would prevent malicious attacks, until 51% of the nodes would be compromised. The proposed system AIMS (Aadhaar Identity Management System) provides self sovereign identity to the people through which one can create and control their verifiable credentials without any centralized authority and gives control over how their personal data is shared and used. This article also provides the comparative analysis of consensus algorithm which determines the performance and security of the blockchain system.
