We present the results of two studies that together offer a detailed analysis of the smartphone locking mechanisms currently available to billions of smartphone users worldwide. An online survey (N=8,286), conducted in eight different countries, sheds light on people's reasons for choosing their screen lock method and demonstrates significant crosscultural differences in attitudes towards this subject. In a separate monthlong field study (N=134), we studied how existing lock screen mechanisms provide users with distinct tradeoffs between usability and security, identifying areas where both could be improved.<\/jats:p>","DOI":"10.1145\/3036699.3036712","type":"journal-article","created":{"date-parts":[[2017,4,10]],"date-time":"2017-04-10T12:27:17Z","timestamp":1491827237000},"page":"42-46","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["THE ANATOMY OF SMARTPHONE UNLOCKING"],"prefix":"10.1145","volume":"20","author":[{"given":"Nathan","family":"Malkin","sequence":"first","affiliation":[{"name":"University of California, Berkeley"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marian","family":"Harbach","sequence":"additional","affiliation":[{"name":"International Computer Science Institute, Berkeley, CA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"De Luca","sequence":"additional","affiliation":[{"name":"Google, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Serge","family":"Egelman","sequence":"additional","affiliation":[{"name":"University of California, Berkeley, and International Computer Science Institute, Berkeley, CA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2017,1,5]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-07620-1_11"},{"volume-title":"Proceedings of the 4th USENIX Conference on Offensive Technologies (WOOT'10)","year":"1925","author":"Aviv Adam J.","key":"e_1_2_1_2_1"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/1935701.1935740"},{"key":"e_1_2_1_4_1","volume-title":"Lecture Notes in Computer Science","volume":"7397","author":"Bonneau Joseph","year":"2012"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/2207676.2208544"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1145\/2660267.2660273"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/2858036.2858267"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/2858036.2858273"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1145\/1968613.1968647"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1145\/2536714.2536718"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1145\/2536853.2536944"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1145\/2508859.2516700"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1145\/2702123.2702212"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1145\/2702123.2702202"},{"key":"e_1_2_1_15_1","doi-asserted-by":"publisher","DOI":"10.1109\/ICNP.2014.43"}],"container-title":["GetMobile: Mobile Computing and Communications"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/3036699.3036712","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/dl.acm.org\/doi\/pdf\/10.1145\/3036699.3036712","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,18]],"date-time":"2025-06-18T03:50:26Z","timestamp":1750218626000},"score":1,"resource":{"primary":{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/3036699.3036712"}},"subtitle":["Why and How Android Users Around the World Lock their Phones"],"short-title":[],"issued":{"date-parts":[[2017,1,5]]},"references-count":15,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2017,1,5]]}},"alternative-id":["10.1145\/3036699.3036712"],"URL":"https:\/\/doi.org\/10.1145\/3036699.3036712","relation":{},"ISSN":["2375-0529","2375-0537"],"issn-type":[{"type":"print","value":"2375-0529"},{"type":"electronic","value":"2375-0537"}],"subject":[],"published":{"date-parts":[[2017,1,5]]},"assertion":[{"value":"2017-01-05","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
