Pooranian, Z., Shojafar, M., Taheri, R. and Tafazolli, R. (2025) PASCOINFOG/PASFOG: privacy-preserving data deduplication algorithms for fog storage systems. IEEE Consumer Electronics Magazine, 14 (1). pp. 37-45. ISSN 2162-2256 doi: 10.1109/MCE.2023.3333559

Abstract/Summary

The forthcoming Fog storage system should provide end users with secured and faster access to cloud services and minimise storage capacity using data deduplication. This method stores a single copy of data and provides a link to the cloud/fog owners. In client-side data deduplication, the system can reduce network bandwidth levels by duplicate check. This solution fails to cover user privacy and optimise the latency of real-time communications. Motivated by this, this magazine paper develops PrivAcy-preServing data deduplication in Fog stOraGe system (PASFOG) as a data deduplication protocol implemented between cloud storage and users to mitigate brute-force and poison attacks. PASFOG is implemented in fog computing to reduce real-time delay and communication when performing duplicate checks. Also, we propose PrivAcypreServing data dedupliCatiOn in blockchaIN-based Fog stOraGe system (PASCOINFOG) utilised blockchain techniques to realise a reliable system. In PASCOINFOG, when users want to send chunks to the cloud/fog nodes, process the duplicate check and create a new block for the blockchain to reduce real-time latency/communication and protect the cloud from attackers. The proposed protocols can enhance user privacy and reduce real-time communication delay, crucial for consumer electronics applications such as cloud storage and IoT devices.
