Smartwatches can be said to be the most representative product in wearable markets, and involve various hardware technologies in order to overcome the limitations of small hardware. Motion recognition sensors are a representative example of those hardware technologies. However, smartwatches and motion recognition sensors that can be worn by users may pose security threats of password pattern leakage. In the present paper, passwords are inferred through experiments to obtain password patterns inputted by users using motion recognition sensors, and verification of the results and the accuracy of the results is shown.<\/jats:p>","DOI":"10.3390\/sym9070101","type":"journal-article","created":{"date-parts":[[2017,6,30]],"date-time":"2017-06-30T10:04:58Z","timestamp":1498817098000},"page":"101","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Threats of Password Pattern Leakage Using Smartwatch Motion Recognition Sensors"],"prefix":"10.3390","volume":"9","author":[{"given":"Jihun","family":"Kim","sequence":"first","affiliation":[{"name":"Computer Engineering, Yeungnam University, Gyeongsan, Gyeongbuk 38541, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7408-3804","authenticated-orcid":false,"given":"Jonghee","family":"Youn","sequence":"additional","affiliation":[{"name":"Computer Engineering, Yeungnam University, Gyeongsan, Gyeongbuk 38541, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"45","DOI":"10.1145\/2629633","article-title":"Wearables: Has the age of smartwatches finally arrived?","volume":"58","author":"Rawassizadeh","year":"2015","journal-title":"Commun.
