Development of a Hybrid Blockchain-Based File Sharing System in a Cloud Environment

Abstract

Conventional file storage and sharing systems encounter issues with security vulnerabilities, transparency shortcomings, and ineffective distribution. This initiative introduces an innovative blockchain-based framework for secure file sharing, addressing these challenges through the utilization of blockchain, Interplanetary File System (IPFS), and Advanced Encryption System (AES) encryption. The system uses a blockchain network to record file metadata like ownership, timestamps, and access permissions, ensuring data transparency and integrity. AES encryption secures data confidentiality, while IPFS efficiently distributes file chunks across nodes, enhancing availability and reliability. This approach creates a secure, efficient, and transparent file sharing solution. Performance evaluations demonstrate that the developed model outperforms existing models in terms of response time and requests per second, highlighting its efficiency under load.
