Consent Management System Based on User Data Security and Privacy Using Hyperledger Fabric Blockchain

Abstract

The challenge of safeguarding user data privacy becomes pronounced when private data is outsourced to cloud services, potentially exposing it to unauthorized access. The challenge of centralized storage of user data introduces heightened security risks and a dependence on a single authority, posing difficulties in safeguarding against internal breaches. This study is dedicated to advancing user privacy and data security, especially in scenarios involving the sharing of sensitive information within or across organizations, including small enterprises functioning in a distributed environment. The research introduces a consent management framework built on Blockchain technology, with a particular focus on user consent management. This framework is designed to prioritize the principles of privacy, security, scalability, and data integrity. It utilizes Hyperledger Fabric which is a permissioned distributed ledger solution, and incorporates Hyperledger Composer to establish and maintain a secure record of user data. To enhance the security of stored data, the framework incorporates the Interplanetary File System (IPFS) and employs a unique cryptographic public key encryption algorithm for data encryption. The overarching aim of this research is to establish a robust security solutions foundation against cyber threats by harnessing the inherent capabilities of blockchain technology, ultimately strengthening the security landscape for sharing user information.
