Recently, social networks have become one of the most popular tools for communication and information exchanges, and people are constructing social relationships and conducting social interactions over social networks. In this paper, we focus on digital forensics on social networks. Specifically, considering the emerging of cloud computing and big data tides, we propose a cloud based forensics framework for social networks, where social networking data is collected, stored, and analyzed through a multi-layered modularity framework using cloud computing techniques, including virtualization, distributed processing and storage, and collaboration. Besides, we also provide a case study on social link prediction, which is, reasoning links between nodes to infer possible relationships between criminals.
