Abstract
The increasing utilization of cloud services by mobile apps on smartphones leads to serious privacy concerns. While users can quantify the cloud usage of their apps, they often cannot relate to involved privacy risks. In this paper, we apply comparison-based privacy, a behavioral nudge, to the cloud usage of mobile apps. This enables users to compare their personal app-induced cloud exposure to that of their peers to discover potential privacy risks from deviation from normal usage behavior. Since cloud usage statistics are sensitive, we protect them with k-anonymity and differential privacy.
