An efficient blockchain-based framework for file sharing

Area of Science:

• Computer Science
• Information Security
• Distributed Systems

Background:

• Traditional centralized file sharing systems incur high maintenance costs and suffer from confidentiality breaches.
• Lack of effective file management in current systems leads to data loss and uncontrolled sensitive information.
• Existing file transfer methods lack robust tamper detection and supervision mechanisms.

Purpose of the Study:

• To design a secure blockchain-based system architecture for electronic document sharing.
• To address challenges in tamper detection and supervision within file transfer processes.
• To improve the security, control, reliability, and traceability of file sharing.

Main Methods:

• Implementation of an efficient blockchain model integrated with a distributed storage system.
• Utilization of asymmetric encryption technology for secure data handling.
• Proposal of a novel consensus mechanism inspired by Delegated Proof of Stake (DPoS) and Practical Byzantine Fault Tolerance (PBFT).

Main Results:

• The proposed framework demonstrates enhanced control, reliability, and traceability in file sharing.
• Experimental results indicate significantly higher throughput compared to existing secure file sharing schemes.
• The system effectively mitigates issues related to tamper detection and supervision.

Conclusions:

• The developed blockchain-based system offers a secure and efficient solution for electronic document sharing.
• The novel consensus mechanism contributes to improved performance and security in distributed file sharing.
• This architecture provides a robust foundation for confidential and traceable file transfer over the internet.
