User privacy and data trustworthiness in mobile crowd sensing

Daojing He, Sammy Chan, Mohsen Guizani
2015 IEEE wireless communications  
DATA TRUSTWORTHINESS Data trustworthiness and user privacy preservation are two conflicting objectives in an MCS application.  ...  Strong mechanisms for protecting privacy might influence data trustworthiness. On the other hand, protecting the data trustworthiness counteracts the mechanisms for preserving privacy.  ...  If participants are malicious, they would provide falsified data and it is difficult to identify them especially when different task actions are not linked due to privacy protection.  ...
