Blockchain Enabled Privacy Preservation System for Web Applications

Abstract

Modern web applications permanently process large quantities of sensitive information such as personal records, financial information, confidential documents. Typical centralized architectures for web systems are highly susceptible to data breaches, unauthorized access and single-point failures. These limitations pose severe problems in preserving user privacy and data integrity in distributed environment . Block chain technology offers a decentralized and tamperproof framework for secure storage and controlled access of digital information without being based on a single trusted authority. By combining cryptographic hashing, distributed ledger mechanisms and permission-based access control, blockchain can do a lot to improve privacy preservation for web applications. This paper presents the idea of a blockchain enabled privacy preservation system for web applications that provides security of data storage, transparency of accessing verification, and against unauthorized modification.
