Efficient and Privacy-Aware Data Aggregation in Mobile Sensing

Efficient and Privacy-Aware Data Aggregation in Mobile Sensing The proliferation and ever-increasing capabilities of mobile devices such as smart phones give rise to a variety of mobile sensing applications. This paper studies how an untrusted aggregator in mobilesensing can periodically obtain desired statistics over the data contributed by multiple mobile users, without compromising the privacy of each user. Although there are some existing works in this area, they […]
