Blockchain Based Secure Digital Identity Verification System for Robust Documents

Abstract

Current digital identity verification systems, like DigiLocker, predominantly rely on centralized storage and often lack robust privacy and security measures, making them susceptible to data breaches and unauthorized access. Existing digital identity verification systems, such as DigiLocker, primarily focus on providing a centralized storage solution for digital documents but often fall short in ensuring comprehensive privacy and security. These systems are vulnerable to data breaches and unauthorized access, posing significant risks to users. This paper proposes a novel approach for securely creating and verifying digital identities for shopkeepers through the integration of Blockchain technology and OTP split verification, augmented by a blockchain-based cloud server. a novel approach to integrating cloud servers as fundamental blocks within a blockchain architecture. This hybrid system leverages both traditional physical nodes and cloud servers, ensuring enhanced security, scalability, and reliability for storage. This concept introduces a hybrid system where cloud servers are integrated as fundamental blocks within a blockchain architecture, enhancing the overall security, scalability, and reliability of data storage. The proposed system enables shopkeepers to generate self-sovereign IDs that are securely stored on a decentralized, immutable blockchain, verified by government authorities to ensure authenticity. Privacy is preserved through advanced encryption techniques and regular data integrity checks. Additionally, the OTP split verification method enhances security by distributing parts of a unique OTP across multiple communication channels, reducing the risk of interception. This innovative approach offers a robust, scalable, and privacy-preserving solution for digital identity management.
