TrustMeter: A trust assessment scheme for collaborative privacy mechanisms in participatory sensing applications

Delphine Christin, Daniel Rodriguez Pons-Sorolla, Matthias Hollick, Salil S. Kanhere
2014 2014 IEEE Ninth International Conference on Intelligent Sensors, Sensor Networks and Information Processing (ISSNIP)  
We investigate the TrustMeters performance under different attacks by means of extensive simulations, and show that it succeeds in quarantining malicious users in most analyzed scenarios.  ...  Users can mutually preserve their privacy by opportunistically exchanging sensor readings during physical meetings, thus breaking the link between the collected data and their permanent identities.  ...  Therefore, we focus on solutions tailored to delay tolerant and opportunistic networks [11] sharing the more similarities with our system model (see Sec. II-A).  ...
