【摘要】:智能手表上搭載了加速度計、陀螺儀等運動傳感器,且會隨著手部運動而產(chǎn)生位移,使通過智能手表竊取用戶外部鍵盤輸入成為了可能。研究了智能設(shè)備上基于6軸加速度計/陀螺儀來推斷用戶鍵盤輸入的可行性,建立了用戶進行鍵盤輸入時的運動模型來對手部運動進行分類識別。當(dāng)用戶執(zhí)行敏感輸入,如在數(shù)字鍵盤上輸入密碼時,可根據(jù)傳感器信息推斷出密碼。經(jīng)實驗驗證,該方法可有效識別4位PIN碼,證明此安全問題值得人們重視。
[Abstract]:The smartwatch is equipped with accelerometers, gyroscopes and other motion sensors, and will shift with the movement of the hand, making it possible to steal the user's external keyboard input through the smartwatch. The feasibility of inferred user keyboard input based on 6-axis accelerometer / gyroscope on intelligent device is studied, and the motion model of user keyboard input is established to classify and recognize hand motion. When a user performs sensitive input, such as a password on a digital keyboard, the password can be inferred from the sensor information. The experimental results show that the method can effectively identify 4-bit PIN codes, which proves that this security problem is worthy of attention.
