Void - Verification and optimization of ID's

Overview

Void is a decentralized application (dApp) designed to revolutionize identity verification and fetching realtime details through ID's. In scenarios like hotel check-ins, where you typically submit your Aadhaar card containing sensitive personal information, Void allows you to prove your identity without revealing unnecessary details. Our platform encrypts and decrypts documents in a way that only the required, filtered information is revealed, ensuring your privacy. Deployed at https://knowme-zc44.onrender.com/

The application leverages Polygon for smart contracts Anonaadhar for Aadhaar verification TheGraph for querying blockchain data The result is a seamless experience where the user simply uploads a document and selects the details to reveal. All the verification, authorization, and contract deployment happens instantly, ensuring user privacy. Additionally, authorities can perform real-time monitoring in tourist areas through graph queries for any discrepancies.
