Multi-mode Network Analysis under Differential Privacy

Abstract With the advent of big data era and advancement social network analysis, public is increasingly concerned about privacy protection in today’s complex networks. For past few years, rapid development differential (DP) technology, as a method with reliable theoretical basis, can effectively solve key problem how to “disassociate” personal information This paper focuses on multi-mode heterogeneous model which has attracted lot attention field research. It introduces its application networks briefly first, then proposes centrality-analysis based DP typical network, i.e. network. The calculation principle applicable scenarios are discussed. Then, utility analyzed evaluated through experimental simulation. Possible improvement algorithm above prospected end.
