Rumor Spreading with Cross Propagation in Multilayer Social Networks.

Social networks have achieved great success by making social interaction online. Malicious users, whereas, make use of social networks to spread rumors. Recent researches manifest that the union of social applications can reach better efficiency. Unfortunately, novel security threats are emerging when malicious users take advantage of this opportunity to spread rumors from a single social network to multilayer networks. In this paper, concerning the cross propagation in the multilayer social networks, the S2IR2 model is therefore proposed to analyze the rumor spreading. The rumor spreading process is molded by mean-field equations. With the simulations of various parameters, the numerical results give the performances of propagation speed and range. For restraining the rumor spreading, the security strategies are concluded.
