CryptoCard: Blockchain-Powered Library Card Management System

Abstract

Abstract: Institutions such as libraries often face challenges in managing and verifying the authenticity of issued library cards. Traditional methods of card issuance and verification may be susceptible to fraud and manipulation. To address these challenges, we present a Blockchain-Enabled Library Card Management System. Our system leverages blockchain technology to securely store and manage library card data. Each library card issuance is recorded as a block on the blockchain, ensuring transparency, immutability, and tamper-resistance. Digital signatures generated using the Elliptic Curve Digital Signature Algorithm (ECDSA) are employed to authenticate the integrity of each card. The system allows users to easily issue library cards by providing their personal information and a photo. The generated library card includes user details and a unique identifier, along with a digital signature to validate its authenticity. Additionally, users can verify the validity of library cards by querying the blockchain and verifying the digital signatures. By employing blockchain technology, our system enhances the security and trustworthiness of library card management, reducing the risk of fraud and ensuring the integrity of issued cards. It provides a robust and efficient solution for libraries to manage their card issuance process whilemaintaining data integrity and security.
