Blockedge-Based Private Virtual Storage for Personal Data Privacy Protection
Jung-Hyok Kwon, Sol-Bee Lee, Eui‐Jik Kim · 2024
This paper presents a BlockEdge-based private virtual storage, abbreviated BPVS, which aims to provide scalable and costless private virtual storage while protecting data privacy using a blockchain. The private virtual storage is built by reusing the remaining storage space of the existing Internet of Things (IoT) devices. Data access for private virtual storage is restricted only to authorized users whose authority is verified by a blockchain-based decentralized identity (DID). In BPVS, the BlockEdge is a special device responsible for storage and access management. To verify the feasibility of the BPVS, experimental implementation was conducted. The results demonstrated that BPVS is a practical solution for protecting personal data privacy.
