Sweets: A Decentralized Social Networking Service Application Using Data Synchronization on Mobile Devices

Conventional Social Networking Services (SNSs) or Online Social Networks (OSNs) are implemented based on a centralized architecture, and this centralization causes privacy problems. This paper describes Sweets, a decentralized SNS application that synchronizes tweets among users’ own mobile devices and enables users to retain ownership of their data. Sweets provides user authentication and access control without centralized servers. Sweets improves the data availability using an indirect replication scheme. Experimental results show that Sweets has a feasible performance over a 4G cellular network.
