Decentralized Fingerprinting for Secure Peer-To-Peer Data Exchange of Aadhaar Via Public Key Infrastructure

The evolution of Aadhaar, an identification system executed by the Indian government that provides each citizen with a unique identity, is analyzed within the context of the creation of Unique Identity Authority of India (UIDAI), which distributes and generates user identities based on and biometric and demographic information. The study gives a comprehensive outline of security issues related to the Aadhaar authentication process and analyzes the updates introduced over time. The main objective of this study is to comprehensively cover the security perspectives related to Aadhaar and provide conceivable arrangements to mitigate the security threats through the development and implementation of a decentralized fingerprinting system that uses Public Key Infrastructure (PKI) to empower secure peer-to-peer data exchange leveraging zero-knowledge proofs. The proposed solution shows the necessary data digitally by integrating data logging strategies to keep track of individuals accessing the data ensuring end-to-end encryption. In this way, it empowers Aadhaar holders to selectively disclose their information to authorized entities while preserving the confidentiality and integrity of the data.
