The mobile crowdsourcing network (MCN) is a rising network architecture that comprises both crowdsensing and crowdsourcing computing. It has attracted broad attention in the world because of its powerful ability to deal with increasingly hard problems. Compared to traditional network, it is more vulnerable to be attacked for its generous payment. At the same time, an amount of input data which comes from various sources is delivered among the service providers, end users and participants, and the involved sensitive information may be revealed during the transmission. Moreover, as the characteristics of MCNs, including task crowdsourcing, human involvement, dynamic topology and heterogeneity, both security and privacy issues are more challenging. In this chapter, we review the current MCN architecture and new challenges of security and privacy issues at first. Then, we present some proposed approaches for security assurance and privacy protection in MCNs from three aspects: authentication, reputation and incentive mechanisms. Finally, possible research directions of security and privacy issues in MCNs and plenty of related reference are given.
