In recent years, there has been explosive growth in Smartphone sales, which is accompanied with the availability of a huge number of Smartphone applications (or simply apps). End users or consumers are attracted by the many interesting features offered by these devices and the associated apps. The developers of these apps benefit financially, either by selling their apps directly or by embedding one of the many ad libraries available on Smartphone platforms. In this paper, the authors focus on potential privacy and security risks posed by these embedded or in-app advertisement libraries (henceforth "Ad libraries," for brevity). To this end, they study the popular Android platform and collect 100,000 apps from the official Android Market in March-May, 2011.
