As a result, one user's decisions regarding app permissions can expose the information of other parties. However, research typically focuses on consequences of privacy-related decisions only for the user who makes the decisions. Work on the impact of these decisions on the privacy of others is still relatively scant. We fill this gap with an online study that extends prior work on interdependent privacy in social networking sites to the context of smartphone permissions. Our findings indicate that people typically give less consideration to the implications of their actions for the privacy of others compared to the impact on themselves. However, we found that priming people with information that features others can help reduce this discrepancy. We apply this insight to offer suggestions for enhancing permission-specification interfaces and system architectures to accommodate interdependent privacy.<\/jats:p>","DOI":"10.1145\/3479581","type":"journal-article","created":{"date-parts":[[2021,10,19]],"date-time":"2021-10-19T02:30:11Z","timestamp":1634610611000},"page":"1-35","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":14,"title":["Won't You Think of Others?: Interdependent Privacy in Smartphone App Permissions"],"prefix":"10.1145","volume":"5","author":[{"given":"Maximilian","family":"Marsch","sequence":"first","affiliation":[{"name":"Technical University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jens","family":"Grossklags","sequence":"additional","affiliation":[{"name":"Technical University of Munich, Munich, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sameer","family":"Patil","sequence":"additional","affiliation":[{"name":"University of Utah, Salt Lake City, UT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2021,10,18]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/SP.2016.33"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/MSP.2009.163"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.aaa1465"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1257\/jel.54.2.442"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/1094428114547952"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.3991\/ijim.v11i3.6605"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/2702123.2702210"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1109\/SP40000.2020.00006"},{"key":"e_1_2_1_9_1","volume-title":"A Report for the ACCC.
