Aadhaar Secure: An Authentication System for Aadhaar Base Citizen Services using Blockchain

In the past decades, people had to carry a bunch of documents for acquiring citizen beneficiary services such as opening a bank account, issue of a new sim card, new gas connection, Pradhan Mantri Jan Dhan Yojana etc. In this digital era, Aadhaar is acting as the driving force to gain all citizen services. Unfortunately, lot of security breaches have been occurred on compromising the Aadhaar details which is stored in the database. Providing security to Aadhaar data and mitigate the misuse of other's Aadhaar data to gain citizen services by unauthenticated users is a main concern. Hence, a secure and authenticated system is required to store and use the Aadhaar details securely by authenticated user. In this paper, we are proposing a secure authenticated system which uses IPFS to store finger prints of the customers and blockchain is used to store the Aadhaar details of the registered citizens. In this system, the biometric is integrated with blockchain to secure Aadhaar details and authenticate the customers before providing any citizen services. The system also generates the Aadhaar card after passing redundancy check for customers who do not have Aadhaar card to access the citizen services. The system is tested and verified for multiple citizen services.
