This work presents a novel writing style-based approach to detect multi-account users on User-Generated Content (UGC) sites. Unlike existing works which emphasize feasibility and privacy leakage, we focus on precise writing style-based multi-account detection. Specifically, we leverage a one-class classification-based approach to detect multi-account behaviors, in which a mutual similarity measurement...
Recent studies have demonstrated that overlay localization can reduce the inter-ISP traffic efficiently, however, fully localized overlays generally impair the streaming quality. In this paper, we first investigate the effects of overlay localization and then present a novel ISP-friendly hierarchical overlay, termed HOPES, to achieve a favorable tradeoff between the inter-ISP traffic and the streaming...
Recently, Cyberlocker services have gained great popularity in the file-sharing market. Driven by tremendous benefits a large number of files such as popular movies are uploaded to Cyberlockers. We explore the profit chain of file-sharing networks based on Cyberlockers and find that an important issue is how to collect the download URLs of popular files stored at different Cyberlockers and share them...
Peer-to-Peer (P2P) media streaming networks have attracted significant research interest recently. However, it is challenging to design live P2P media streaming systems because of the stringent time constraints on the delivered media streams, which require more efficient and resilient overlay. In this paper, we focus on live P2P media streaming networks, a promising application flourishing in the...
