Sybil attacks are one of the most prominent security problems of trust mechanisms in a distributed network with a large number of highly dynamic and heterogeneous devices, which expose serious threat to edge computing based distributed systems. Graphbased Sybil detection approaches extract social structures from target distributed systems, refine the graph via preprocessing methods and capture Sybil nodes based on the specific properties of the refined graph structure. Graph preprocessing is a critical component in such Sybil detection methods, and intuitively, the processing methods will affect the detection performance. Thoroughly understanding the dependency on the graph-processing methods is very important to develop and deploy Sybil detection approaches. In this paper, we design experiments and conduct systematic analysis on graph-based Sybil detection with respect to different graph preprocessing methods on selected network environments. The experiment results disclose the sensitivity caused by different graph transformations on accuracy and robustness of Sybil detection methods.

Intellectual property is inextricably linked to the innovative development of mass innovation spaces. The synthetic development of intellectual property and mass innovation spaces will fundamentally support the new economic model of “mass entrepreneurship and innovation”. As such, it is critical to explore intellectual property service standards for mass innovation spaces and to steer mass innovation spaces to the creation of an intellectual property service system catering to “makers”. In addition, it is crucial to explore intellectual cluster management innovations for mass innovation spaces.
