Nowadays, one of the major privacy challenges is the tremendous amount of permissions requested by applications, which can significantly invade users' privacy, often without their knowledge. In this paper, we provide a comprehensive review of approaches that can be used to report on applications' permission usage, tune permission access, contain sensitive information, and nudge users towards more privacy-conscious behavior. We discuss key shortcomings of privacy enforcement on smartphones so far and identify suitable actions for the future.}, keywords = {Smartphones; Permission Granting; Privacy; Nudging}, tags = {trinics}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2017/2017-pennekamp-pmc-survey.pdf}, misc2 = {Online}, publisher = {Elsevier}, language = {en}, ISSN = {1574-1192}, DOI = {10.1016/j.pmcj.2017.09.005}, reviewed = {1}, author = {Pennekamp, Jan and Henze, Martin and Wehrle, Klaus} } @Inproceedings { 2017-henze-mobiquitous-comparison, title = {Privacy-preserving Comparison of Cloud Exposure Induced by Mobile Apps}, year = {2017}, month = {11}, day = {7}, pages = {543-544}, tags = {trinics}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2017/2017-henze-mobiquitous-comparison.pdf}, misc2 = {Online}, publisher = {ACM}, booktitle = {Proceedings of the 14th EAI International Conference on Mobile and Ubiquitous Systems: Computing, Networking and Services (MobiQuitous) - Poster Session, Melbourne, VIC, Australia}, language = {en}, ISBN = {978-1-4503-5368-7}, DOI = {10.1145/3144457.3144511}, reviewed = {1}, author = {Henze, Martin and Inaba, Ritsuma and Fink, Ina Berenice and Ziegeldorf, Jan Henrik} } @Inproceedings { 2017-henze-mobiquitous-cloudanalyzer, title = {CloudAnalyzer: Uncovering the Cloud Usage of Mobile Apps}, year = {2017}, month = {11}, day = {7}, pages = {262-271}, abstract = {Developers of smartphone apps increasingly rely on cloud services for ready-made functionalities, e.g., to track app usage, to store data, or to integrate social networks. At the same time, mobile apps have access to various private information, ranging from users' contact lists to their precise locations. As a result, app deployment models and data flows have become too complex and entangled for users to understand. We present CloudAnalyzer, a transparency technology that reveals the cloud usage of smartphone apps and hence provides users with the means to reclaim informational self-determination. We apply CloudAnalyzer to study the cloud exposure of 29 volunteers over the course of 19 days. In addition, we analyze the cloud usage of the 5000 most accessed mobile websites as well as 500 popular apps from five different countries. Our results reveal an excessive exposure to cloud services: 90 \% of apps use cloud services and 36 \% of apps used by volunteers solely communicate with cloud services. Given the information provided by CloudAnalyzer, users can critically review the cloud usage of their apps.}, keywords = {Privacy; Smartphones; Cloud Computing; Traffic Analysis}, tags = {trinics}, url = {https://www.comsys.rwth-aachen.de/fileadmin/papers/2017/2017-henze-mobiquitous-cloudanalyzer.pdf}, misc2 = {Online}, publisher = {ACM}, booktitle = {Proceedings of the 14th EAI International Conference on Mobile and Ubiquitous Systems: Computing, Networking and Services (MobiQuitous '17), November 7-10, 2017, Melbourne, VIC, Australia}, event_place = {Melbourne, VIC, Australia}, event_date = {November 7-10, 2017}, language = {en}, ISBN = {978-1-4503-5368-7}, DOI = {10.1145/3144457.3144471}, reviewed = {1}, author = {Henze, Martin and Pennekamp, Jan and Hellmanns, David and M{\"u}hmer, Erik and Ziegeldorf, Jan Henrik and Drichel, Arthur and Wehrle, Klaus} } @Inproceedings { 2017-henze-tma-cloudemail, title = {Veiled in Clouds?
