Data retrieval and privacy enhancing hybrid P2P-cloud storage system
Gi Seok Park, Hwangjun Song · 2014
In this work, we present a novel fountain code-based hybrid storage system that combines cloud storage with P2P storage. In the cloud storage system, all the data are consistently stored at server clusters but the data may be exposed to others accessing server clusters. On the other hand, in the P2P storage system, the data are distributed to a group of participating peers but the data retrieval may be significantly degraded. The proposed hybrid system is designed to provide the desired data retrieval with a short upload time and maintain the privacy to avoid other users from reading the contents.
