Aware: Controlling App Access to I/O Devices on Mobile Platforms [article]

Giuseppe Petracca, Ahmad Atamli, Yuqiong Sun, Jens Grossklags and Trent Jaeger
2016 arXiv   pre-print
Contemporary mobile operating systems fail to prevent such misuse of I/O devices by authorized apps due to lack of binding between users' interactions and accesses to I/O devices performed by these apps  ...  In this paper, we propose Aware, a security framework for authorizing app requests to perform operations using I/O devices, which binds app requests with user intentions to make all uses of certain I/O  ...  On average, there are 8 requests per minute by processes running apps to request permission to access sensitive resources [36] . 10 The timer is used to support apps that require users to keep pressing  ...

Flash Drive Lifespan *is* a Problem

Tao Zhang, Aviad Zuck, Donald E. Porter, Dan Tsafrir
2017 Proceedings of the 16th Workshop on Hot Topics in Operating Systems - HotOS '17  
This paper started as a simple experiment: measuring whether the lifespan of flash devices in smartphones and other mobile devices, match the estimates.  ...  To our surprise, we find that, in a matter of days, simple, unprivileged applications can render the drive of several smartphones (and thus, the phone) inoperable.  ...  This work was done in part while Porter and Zhang were at Stony Brook University.  ...

Li Lyna Zhang, Chieh-Jan Mike Liang, Zhao Lucis Li, Yunxin Liu, Feng Zhao, En-Hong Chen
2018 IEEE Transactions on Mobile Computing  
To this end, we propose to use sensitivity analysis to infer whether an app requests sensitive on-device resources/data that are not required for its expected functionality.  ...  We build on the direction of risk rating as the way to communicate app-specific privacy risks to end users.  ...  Automated Testing of Mobile Apps The community has invested efforts in detecting and protecting users from privacy risks.  ...

Contextual Permission Models for Better Privacy Protection

Primal Wijesekera
2018 Zenodo  
Smartphone platforms use permission systems to regulate access to sensitive resources.  ...  We found that when the application requesting the permission is running invisibly to the user, they are more likely to deny applications access to protected resources.  ...  This data could be immensely valuable for future research in privacy, mobile user behavior, measurements, etc.  ...

For example, a user might be surprised to find that an augmented-reality makeup app extracts text from the camera's view in addition to detecting faces.  ...  However, because camera permissions for existing mobile operating systems are coarse (i.e., an app may access a camera's entire view or none of it), users are vulnerable to visual privacy leaks.  ...  Studies suggest that the users aware of the nuances of the app do not tend to allow the resource access as often [9, 32] .  ...
