| 触摸屏屏幕锁定设计的初衷是为了防止用户的误操作，并未考虑到安全性，为此设计了一种以安全性为核心的全新的解锁方式.该解锁方式是基于行为密码的节奏性点触输入手势，节奏识别算法能够智能地识别用户在屏幕上敲击的节奏序列，提取节奏特征，形成解锁密钥.实验结果表明，该解锁方式能够较好地匹配节奏密钥，安全性能也大为提高;并且，节奏识别以个人的乐感体会为基准，注重用户体验，具备快捷性、娱乐性、可靠性等人机交互友好的特征. |

| Abstract: |
| The screen lock of touch screen devices is designed to prevent the users' misuse without taking security into account. To solve this problem, this study provides a design of a secure scheme to unlock the touch screen. Unlike the traditional modes that unlock the touch screen by sliding the sliders or identifying the graphics and images, the presented design is a method to create a rhythm key based on the tapping gestures. The rhythm recognition algorithm is able to identify the rhythm sequence tapped on the screen, extracting rhythm features and creating the keys. Through testing, the new scheme can better match the rhythm gestures and improve the information security greatly. Meanwhile, as a new unlock method and relating to the individual's sense of music experience, the rhythm recognition focus on users' experience such as convenience, entertainment and reliability, all of which are human-computer interaction-friendly features. |
