With the proliferation of sensor-embedded mobile computing devices, participatory sensing is becoming popular to collect information from and outsource tasks to participating users. These applications deal with a lot of personal information, e.g., users' identities and locations at a specific time. Therefore, users need to pay a deeper attention to privacy and anonymity. However, from a data consumer's point of view, they want to know the source of the sensing data, i.e., the identity of the sender, in order to evaluate how much the data can be trusted. "Anonymity" and "Trust" are two conflicting objectives in participatory sensing networks and there are no existing research efforts which investigated the possibility of achieving both of them at the same time.
