BLOCKCHAIN-BASED DATA INTEGRITY VERIFICATION SYSTEM

Abstract

The present invention relates to a blockchain-based system for ensuring data integrity and authenticity. The system employs a cryptographic hash generator to create unique identifiers for data, which are then stored on a decentralized blockchain network. Each data transaction is recorded in a block containing the cryptographic hash, timestamp, and other metadata, ensuring that any tampering or alteration of the data is immediately detectable. The blockchain network is validated by multiple independent nodes, providing a transparent and immutable record of data changes. A smart contract automates the process of storing and verifying data integrity, enabling real-time, automated verification without the need for manual intervention. This system can be applied across various industries, including digital document management, supply chain management, and healthcare, ensuring that data remains secure, verifiable, and transparent throughout its lifecycle.

Specification

Description:The embodiments of the present invention generally relates to the field of data security and integrity, specifically to systems and methods for verifying the authenticity of data using blockchain technology. The invention provides a solution for ensuring that digital data remains immutable, secure, and transparent during storage and transmission, addressing issues related to data tampering, unauthorized modifications, and data breaches in various applications such as finance, healthcare, supply chain management, and secure communication networks.
