This is highly beneficial for both vendors and publishers who are the owners of the advertising platforms, such as websites and app developers, but at the same time creates a serious privacy threat for users who expose their consumer interests. In this paper, we categorize the available ad-distribution methods and identify their limitations in terms of security, privacy, targeting effectiveness and practicality. We contribute our own system, which utilizes opportunistic networking in order to distribute targeted adverts within a social network. We improve upon previous work by eliminating the need for trust among the users (network nodes) while at the same time achieving low memory and bandwidth overhead, which are inherent problems of many opportunistic networks. Our protocol accomplishes this by TI - Private and Secure Distribution of Targeted Advertisements to Mobile Phones JF - Future Internet DO - 10.3390/fi9020016 DA - 2017-05-01 UR - https://www.deepdyve.com/lp/unpaywall/private-and-secure-distribution-of-targeted-advertisements-to-mobile-X08EpSj4DA DP - DeepDyve ER -
