背景技术Background technique
二十世纪末至二十一世纪初的近二十多年是移动通信高速发展的黄金成长阶段，移动电子设备得到了广泛的普及和应用，手机电子产品的更新速度让人目不暇接，不但手机通信制式从2G GSM到4G LTE的跨越式发展，而且手机也从只具有单一通话功能的电子设备演变成一个包括通话管理、游戏娱乐、办公记事等各类应用软件在内的智能运行平台。智能移动终端通常保存了用户大量重要信息，比如通信录、短信、照片、文字影音资料，但同时终端设备的的存储空间是有限的，为了能保证智能移动终端运行顺畅，用户需要经常对终端设备上存储的文件进行整理，，这其中删除和剪切是非常常见的操作。The nearly 20 years from the end of the 20th century to the beginning of the 21st century was the golden growth stage of the rapid development of mobile communications. Mobile electronic devices have been widely popularized and applied. The update speed of mobile phone electronic products is dizzying. The leapfrog development from 2G GSM to 4G LTE, and the mobile phone has evolved from an electronic device with only a single call function to an intelligent operating platform including various application software such as call management, game entertainment, and office notes. Smart mobile terminals usually store a large amount of important information of the user, such as address books, text messages, photos, text and audio-visual materials, but at the same time, the storage space of the terminal device is limited. In order to ensure the smooth operation of the smart mobile terminal, users need to often To organize the files stored on the computer, deleting and cutting are very common operations.
目前，指纹识别传感器更多的使用在加密领域，比如说对文件加密，手机加密，以及延伸领域如指纹识别解锁等，但通常指纹识别解锁只是一次性验证，比如说屏幕的密码解锁，只要指纹密码成功验证完毕后就不需要再次验证了，之后一旦智能移动终端交给周边的人，他人就可以对智能移动终端进行各式操作，比如对重要信息进行处理--删除、剪切等操作，一旦某些文件被删除或者被误操作剪切以及拖动到别的文件夹，再想重新找回来，就比较麻烦或者更尤甚的是造成不可逆的重要信息丢失。现在亟待一种方便快捷的对重要信息进行操作赋予加密手段的方法，既能对重要信息的操作进行加密，又不会对操作便捷性造成影响。At present, fingerprint recognition sensors are more used in the field of encryption, such as file encryption, mobile phone encryption, and extended fields such as fingerprint recognition and unlocking, etc., but usually fingerprint recognition and unlocking are only one-time verification, such as password unlocking of the screen, as long as the fingerprint After the password is successfully verified, there is no need to verify again. Once the smart mobile terminal is handed over to the surrounding people, others can perform various operations on the smart mobile terminal, such as processing important information-deleting, cutting, etc. Once some files are deleted or cut and dragged to other folders by mistake, it will be more troublesome or even more irreversible loss of important information if you want to retrieve them again. Now there is an urgent need for a convenient and quick method of assigning encryption means to the operation of important information, which can not only encrypt the operation of important information, but also not affect the convenience of operation.

■步骤S0、用户指纹录入步骤，该步骤针对如果是首次使用的智能移动终端设备的情况，之前用户必然没有录入任何有效的指纹图像数据，该步骤还针对如果是更换智能移动终端设备用户的情况，之前用户的指纹图像数据必然也是无效的，也要重新录入用户指纹图像数据。■Step S0, user fingerprint entry step, this step is aimed at the situation that if the smart mobile terminal device is used for the first time, the user must not have entered any valid fingerprint image data before, and this step is also aimed at the case of changing the user of the smart mobile terminal device , the previous user's fingerprint image data must also be invalid, and the user's fingerprint image data must be re-entered.
该步骤具体为This step is specifically
S01、智能移动终端操作系统接收用户发送的指纹录入设置请求；S01. The operating system of the smart mobile terminal receives the fingerprint entry setting request sent by the user;
S02、智能移动终端操作系统启动指纹识别传感器响应用户请求并获取用户录入的指纹；S02. The operating system of the smart mobile terminal activates the fingerprint recognition sensor to respond to the user request and obtain the fingerprint entered by the user;
S03、智能移动终端操作系统存储用户录入的指纹图像数据。S03. The operating system of the smart mobile terminal stores the fingerprint image data entered by the user.
■步骤S1、智能终端终端检测到用户已选中将要进行操作的目标信息(比如文件、文件夹、通讯录、相片，但不局限于以上举例)，指纹识别传感器启动进入指纹识别工作状态。■Step S1, the smart terminal terminal detects that the user has selected the target information to be operated (such as files, folders, contacts, photos, but not limited to the above examples), and the fingerprint recognition sensor starts to enter the fingerprint recognition working state.
■步骤S2、智能移动终端捕获用户通过指纹识别传感器输入的第一指纹图像数据，记录下第一指纹捕获时间和第一指纹捕获位置。■Step S2, the smart mobile terminal captures the first fingerprint image data input by the user through the fingerprint identification sensor, and records the first fingerprint capture time and the first fingerprint capture position.
■步骤S3、智能移动终端捕获用户通过指纹识别传感器输入的第二指纹图像数据，记录下第二指纹捕获时间和第二指纹捕获位置。■Step S3, the smart mobile terminal captures the second fingerprint image data input by the user through the fingerprint recognition sensor, and records the second fingerprint capture time and the second fingerprint capture location.
■步骤S4、当所述第一指纹捕获时间和第二指纹捕获时间的时间间隔小于指定时间间隔，判断比较所述第一指纹图像数据、第二指纹图像数据和用户预置指纹图像数据是否三者完全相同，如果上述判断比较结果是相同的，进入下一步骤S5。■Step S4, when the time interval between the first fingerprint capture time and the second fingerprint capture time is less than the specified time interval, judge whether the first fingerprint image data, the second fingerprint image data and the user preset fingerprint image data are three or are completely the same, if the above judgment and comparison results are the same, enter the next step S5.
但如果当所述第一指纹捕获时间和第二指纹捕获时间的时间间隔大于指定时间间隔，则视为此次手势滑动不是一次完整的滑动，中间出现了中断，属于误操作的可能概率极大，故放弃此处指纹图像数据的比对，返回步骤S1，指纹识别传感器仍然处于指纹识别工作状态。However, if the time interval between the first fingerprint capture time and the second fingerprint capture time is greater than the specified time interval, it is considered that the gesture swipe is not a complete swipe, and there is an interruption in the middle, which is likely to be a misoperation. , so the comparison of the fingerprint image data here is abandoned, and returning to step S1, the fingerprint recognition sensor is still in the fingerprint recognition working state.
■步骤S5、根据所述第一指纹捕获位置和第二指纹捕获位置判断手势滑动方向。■Step S5, judging the gesture sliding direction according to the first fingerprint capturing position and the second fingerprint capturing position.
其中，判断手势滑动方向的具体规则如下：Among them, the specific rules for judging the sliding direction of gestures are as follows:
首先，将智能移动终端操作系统将指纹识别传感器的识别区域放在一个直角坐标系中，将智能移动终端设备的左上角为坐标原点，终端设备的上边界定义为水平X轴方向，屏幕的左边界定义为垂直Y轴方向；First, put the recognition area of the fingerprint recognition sensor in a Cartesian coordinate system by the smart mobile terminal operating system, set the upper left corner of the smart mobile terminal device as the coordinate origin, define the upper boundary of the terminal device as the horizontal X-axis direction, and define the left corner of the screen as the coordinate origin. The boundary is defined as the vertical Y-axis direction;
其次，用(e1.getX、e1.getY)表示第一指纹捕获位置e1点的坐标，(e2.getX、e2.getY)表示第二指纹捕获位置e2点的坐标，distanceX表示X轴方向移动的距离，distanceY表示Y轴方向移动的距离；Secondly, use (e1.getX, e1.getY) to represent the coordinates of point e1 of the first fingerprint capture position, (e2.getX, e2.getY) represent the coordinates of point e2 of the second fingerprint capture position, and distanceX represents the distance moved in the X-axis direction Distance, distanceY represents the distance moved in the Y-axis direction;
最后，定义手势滑动方向的具体判断条件为：Finally, the specific judgment conditions for defining the sliding direction of gestures are:
向上滑动判断条件：e1.getY–e2.getY>delta，并且velocityY>velocityX，则方向变量direction＝up；Judgment condition for sliding up: e1.getY–e2.getY>delta, and velocityY>velocityX, then the direction variable direction=up;
向下滑动判断条件：e2.getY–e1.getY>delta，并且velocityY>velocityX，则方向变量direction＝down；Sliding down judgment condition: e2.getY–e1.getY>delta, and velocityY>velocityX, then the direction variable direction=down;
向左滑动判断条件：e1.getX–e2.getX>delta，并且velocityX>velocityY，则方向变量direction＝left；Swipe left judgment condition: e1.getX–e2.getX>delta, and velocityX>velocityY, then the direction variable direction=left;
向右滑动判断条件：e2.getX–e1.getX>delta，并且velocityX>velocityY，则方向变量direction＝right；Swipe right judgment condition: e2.getX–e1.getX>delta, and velocityX>velocityY, then the direction variable direction=right;
其中，delta为判断移动距离的阈值，用于表示滑动的距离至少要大于该阈值时才可以被视为滑动已经进行。Wherein, delta is a threshold value for judging the moving distance, which is used to indicate that the sliding distance must be at least greater than the threshold value before it can be considered that the sliding has been performed.
■步骤S6、调用手势与信息操作映射关系表，根据手势与信息操作映射关系表中规定的手势滑动方向与目标信息操作方式之间的对应关系，匹配出所述步骤S5中判断得到的手势滑动方向对应的目标信息操作方式，并对用户选中的目标信息进行相关操作。■Step S6, calling the gesture and information operation mapping relationship table, and matching the gesture sliding determined in step S5 according to the corresponding relationship between the gesture sliding direction and the target information operation mode specified in the gesture and information operation mapping relationship table The target information operation method corresponding to the direction, and perform related operations on the target information selected by the user.
其中，手势与信息操作映射关系表中手势滑动方向包括向上、向下、向左、向右滑动，目标信息操作方式包括剪切和删除。Wherein, the gesture sliding direction in the gesture and information operation mapping relationship table includes sliding up, down, left, and right, and the target information operation method includes cutting and deleting.
在本实施例中，该步骤S6中手势与信息操作映射关系表中手势滑动方向与目标信息操作方式之间的对应关系具体为：In this embodiment, the corresponding relationship between the gesture sliding direction and the target information operation mode in the gesture and information operation mapping relationship table in step S6 is specifically:
