an undergrad student of mine did this work based on our research on MobiAd, which I found pretty impressive!
With the ever-increasing number of smart phones, a growing num- bers of people view advertisements on their phones and hence the smart phone advertising market has become rich and noticeable. To raise click-through rate and maximize profit, ad brokers ensure their ads are more personalized and targeted. Therefore, they col- lect personal information to build an accurate user profile. The use of sensitive and personal information may raise privacy concerns. In this paper we focus using Delay Tolerant Networking (DTN) to anonymize click reports, aiming to stop attackers tracking and identifying users based on behaviour and location. The results of our simulations prove that a few-hop DTN-based system can protect users’ identity and privacy while not heavily increasing their energy costs.
