臉部辨識於行動裝置螢幕解鎖之研究

臉部辨識是透過擷取人臉特徵來辨別使用者身份的計算機技術。隨著行動科技日新月異，行動裝置取代傳統電腦成為主流的人機互動介面，相關研究領域也越來越被受重視，本研究以人臉辨識技術探討行動裝置的使用者身份鑑別為主要研究。目前普遍的行動裝置使用者仍舊採用密碼驗證進行使用者身份鑑別，此傳統驗證方式存在使用性與資訊安全問題，容易令個人資訊遭受竊取。針對上述問題，本研究提出行動裝置結合人臉辨識技術進行使用者身份鑑別，透過前置鏡頭擷取人臉特徵作為唯一識別資訊來辨別出使用者身份，進而改善密碼驗證存在的缺陷。

Face recognition is a computer technique to capture the feature of the human face for user authentication. In the advanced mobile technology, mobile devices take the place of computers to become the major human-computer interaction. Related researches become more and more popular. This study discusses about the identification of users on the mobile devices. Recently, many users still use passwords for user authentication. However, such traditional password identification may not be secure since the passwords are easily intercepted. To solve this problem, this thesis adopts facial recognition for screen unlocking on the mobile devices.
