Abstract: All the mainstream online social networking (OSN) service providers have a cloud-based infrastructure that is designed with a logically centralized architecture controlled by a single authority, i.e., the OSN service provider. With massive user data controlled by the provider, users are susceptible to loss of control over ownership of their data and privacy, and users may receive false social information due to deceptive advertisements and unfair censorship. This talk mainly concentrates on the design of the architecture for decentralized OSN (DOSN) which is created through participation by a set of autonomous OSN users collaborating with each other without a centralized repository. The social data are stored in local devices and controlled by end-users rather than OSN providers. The talk also covers how we solve challenges in DOSN by creating efficient communication protocols and information dissemination strategies to harness the resources in millions of end devices without losing user’s data privacy.
