技术领域Technical field
本发明实施例涉及指纹识别技术，尤其涉及一种指纹解锁的方法、装置和终端。Embodiments of the present invention relate to a fingerprint identification technology, and in particular, to a method, an apparatus, and a terminal for unlocking a fingerprint.
背景技术Background technique
每一个终端上***与用户进行交流的界面称为终端界面，从此终端开始运行的每一个进程都会依附于这个终端，这个终端称为这些进程的控制终端，当控制终端被关闭时，相应的进程都会自动关闭。The interface between the system and the user on each terminal is called the terminal interface. Every process that starts from this terminal will be attached to this terminal. This terminal is called the control terminal of these processes. When the control terminal is closed, the corresponding process Will automatically close.
目前，利用指纹服务进行解锁的过程中，当终端关闭时，相应的指纹服务的进程就会关闭。当需要用指纹服务解锁时，会触发指纹传感器，Linux内核响应到中断信号，并通过电源管理服务（powermanagerservice）获取该中断信号并发送广播，指纹服务接收到广播之后开始验证指纹，如果验证成功则***点亮屏幕。At present, in the process of unlocking by using the fingerprint service, when the terminal is closed, the process of the corresponding fingerprint service is closed. When the fingerprint service needs to be unlocked, the fingerprint sensor is triggered. The Linux kernel responds to the interrupt signal and obtains the interrupt signal through the power management service (powermanagerservice) and sends a broadcast. After the fingerprint service receives the broadcast, it starts to verify the fingerprint. If the verification succeeds, The system lights up the screen.
技术问题technical problem
由于每次利用指纹服务解锁时，都需要首先通过Linux内核响应到中断信号，并通过电源管理服务获取该中断信号并发送广播，指纹服务接收到广播之后开始验证指纹，所以整个过程会比较浪费时间。 Since each time you use the fingerprint service to unlock, you need to first respond to the interrupt signal through the Linux kernel, and obtain the interrupt signal and send the broadcast through the power management service. After the fingerprint service receives the broadcast, it starts to verify the fingerprint, so the whole process is a waste of time. .

实施例一Embodiment 1
图1为本发明实施例一提供的指纹解锁的方法的流程图，本实施例可适用于使用指纹对终端进行解锁的情况，该方法可以由设置于终端中的硬件或软件来执行，具体包括如下步骤：1 is a flowchart of a method for unlocking a fingerprint according to a first embodiment of the present invention. The present embodiment is applicable to a method for unlocking a terminal by using a fingerprint. The method may be implemented by hardware or software installed in the terminal, including The following steps:
步骤110、在终端处于黑屏状态时，通过指纹传感器检测是否有指纹录入；Step 110: When the terminal is in a black screen state, detecting whether there is fingerprint input by using a fingerprint sensor;
指纹传感器可以有很多种类，比如，可以包括：光学指纹传感器、超声波传感器、半导体指纹传感器等。There are many types of fingerprint sensors, for example, optical fingerprint sensors, ultrasonic sensors, semiconductor fingerprint sensors, and the like.
其中，所述指纹传感器可以为半导体指纹传感器。半导体指纹传感器可以为电容式指纹传感器、或电感式指纹传感器。该电容式指纹传感器工作原理为：在一块集成有成千上万半导体器件的“平板”上，手指贴在其上与其构成了电容的另一面，由于手指平面凸凹不平，凸点处和凹点处接触平板的实际距离大小就不一样，形成的电容数值也就不一样。The fingerprint sensor may be a semiconductor fingerprint sensor. The semiconductor fingerprint sensor can be a capacitive fingerprint sensor or an inductive fingerprint sensor. The capacitive fingerprint sensor works on the other side of a "slab" integrated with thousands of semiconductor devices, on which the finger is attached to the other side of the capacitor, due to the unevenness of the finger plane, bumps and pits. The actual distance of the contact plate is not the same, and the capacitance value formed is different.
电容式指纹传感器中可以包含很多个感应单元，例如包括200×200个感应单元，具体工作过程是：将每个像素点上的电容感应单元充电到某一参考电压，当手指接触到电容式指纹传感器时，感应单元进行放电，因为嵴是凸起的峪是凹下，由于电容值与距离有关，会在嵴和峪处形成不同的电容值，因此嵴和峪处的放电速率也不同，嵴处的感应单元电容量高、放电较慢；而处于峪处的感应单元，电容量低、放电较快，按照放电速率的不同，可以探测到嵴和峪的位置，从而形成指纹图像数据，便于后续与指纹库中的指纹特征进行比对并验证。 The capacitive fingerprint sensor can include a plurality of sensing units, for example, including 200×200 sensing units. The specific working process is: charging the capacitive sensing unit at each pixel to a certain reference voltage, and when the finger touches the capacitive fingerprint When the sensor is used, the sensing unit discharges, because the 嵴 is convex and the 峪 is concave. Since the capacitance value is related to the distance, different capacitance values are formed at the 嵴 and 峪, so the discharge rates at the 嵴 and 峪 are also different. The sensing unit at the location has high capacitance and slow discharge; while the sensing unit at the crucible has low capacitance and fast discharge, according to the different discharge rate, the position of the crucible and the crucible can be detected, thereby forming fingerprint image data, which is convenient. Subsequent comparison and verification of the fingerprint features in the fingerprint library.
当指纹触发或者没有触发指纹传感器，指纹传感器都可以检测到是否有指纹录入，当指纹正确触发指纹传感器时，指纹传感器就会检测到有指纹录入。When the fingerprint triggers or does not trigger the fingerprint sensor, the fingerprint sensor can detect whether there is fingerprint input. When the fingerprint triggers the fingerprint sensor correctly, the fingerprint sensor detects fingerprint input.
步骤120、当通过指纹传感器检测到有指纹录入时，触发指纹传感器采集指纹，并对采集到的指纹进行验证；Step 120: When fingerprint input is detected by the fingerprint sensor, the fingerprint sensor is triggered to collect the fingerprint, and the collected fingerprint is verified;
当指纹传感器检测到有指纹录入时，指纹传感器便会采集指纹，终端对指纹传感器采集到的指纹与指纹库中的指纹进行比对，验证采集到的指纹是否是存储的用于解锁的指纹。When the fingerprint sensor detects fingerprint input, the fingerprint sensor collects the fingerprint, and the terminal compares the fingerprint collected by the fingerprint sensor with the fingerprint in the fingerprint database to verify whether the collected fingerprint is a stored fingerprint for unlocking.
步骤130、若指纹验证成功，则点亮屏幕，并进行解锁。Step 130: If the fingerprint verification is successful, the screen is illuminated and unlocked.
当指纹验证成功，且通知***点亮屏幕之后，可以通知***进行解锁，然后由解锁服务唤醒***其他服务，供用户使用；也可以在点亮屏幕之后，先唤醒***其它服务，然后再解锁。上述***是指终端的操作***，如可以为安卓（android）***等。After the fingerprint verification is successful and the notification system lights up the screen, the system can be notified to unlock, and then the rest service can wake up other services of the system for the user to use; after the screen is lit, the other services of the system can be awake first, and then unlocked. The above system refers to the operating system of the terminal, such as an Android system.
以上所述通知的方式指的是进程间通信的机制，可以是管道（Pipe）、信号（Signal）和跟踪（Trace）等。The manner of notification described above refers to the mechanism of inter-process communication, which may be a pipe, a signal, and a trace.
优选的是Binder机制，Binder机制是一种进程间通信机制。The Binder mechanism is preferred, and the Binder mechanism is an interprocess communication mechanism.
其中，***其它服务可以包括：听音乐、看视频等与指纹服务无关的服务。Among them, other services of the system may include: listening to music, watching videos and other services unrelated to the fingerprint service.
本实施例的技术方案，在终端处于黑屏状态时，通过指纹传感器检测是否有指纹录入，当指纹传感器检测到有指纹录入时，触发指纹传感器采集指纹，并对采集到的指纹进行验证，若验证成功，则点亮屏幕，进行解锁。实现了在终端处于黑屏状态时，只要触发指纹传感器就可以进行指纹验证，若验证成功就可以点亮屏幕，加快了通过使用指纹来点亮屏幕并解锁的时间，提升用户体验。In the technical solution of the embodiment, when the terminal is in a black screen state, the fingerprint sensor detects whether there is fingerprint input. When the fingerprint sensor detects fingerprint input, the fingerprint sensor is triggered to collect the fingerprint, and the collected fingerprint is verified, and if the fingerprint is verified, If successful, the screen will be illuminated and unlocked. When the terminal is in a black screen state, fingerprint verification can be performed only by triggering the fingerprint sensor. If the verification is successful, the screen can be illuminated, and the time for lighting the screen and unlocking by using the fingerprint is accelerated, thereby improving the user experience.
在上述技术方案的基础上，对步骤120进行了优化，具体的，对采集到的指纹进行验证具体可以包括：On the basis of the foregoing technical solution, the step 120 is optimized. Specifically, the verification of the collected fingerprint may include:
提取所述采集到的指纹的指纹特征；Extracting fingerprint features of the collected fingerprints;
将所述采集到的指纹的指纹特征与指纹库中的指纹特征进行比对；Comparing the fingerprint feature of the collected fingerprint with the fingerprint feature in the fingerprint library;
具体的，在使用指纹识别之前，指纹传感器会首先将需要的指纹录入到指纹传感器中，并将所述指纹的指纹特征存储在终端中，当指纹传感器对采集到的指纹进行处理之后，便可以与库存中的指纹特征进行比对。Specifically, before the fingerprint recognition is used, the fingerprint sensor first inputs the required fingerprint into the fingerprint sensor, and stores the fingerprint feature of the fingerprint in the terminal. After the fingerprint sensor processes the collected fingerprint, the fingerprint sensor can Compare with fingerprint features in inventory.
若比对成功，则确定指纹验证成功；If the comparison is successful, it is determined that the fingerprint verification is successful;
若比对失败，则确定指纹验证失败。If the comparison fails, it is determined that the fingerprint verification failed.
如果比对成功，则可以确定此时触发指纹传感器的指纹是已经存储在库存中的指纹，那么指纹传感器就会确定指纹识别成功。If the comparison is successful, it can be determined that the fingerprint triggering the fingerprint sensor at this time is a fingerprint already stored in the inventory, and then the fingerprint sensor determines that the fingerprint recognition is successful.
如果比对不成功，则可以确定库存中没有与触发指纹传感器的指纹所对应的指纹。If the comparison is unsuccessful, it can be determined that there is no fingerprint in the inventory corresponding to the fingerprint that triggered the fingerprint sensor.
通过上述过程，提取指纹特征，与库存中的指纹特征进行比对，可完成指纹验证的过程。Through the above process, the fingerprint feature is extracted and compared with the fingerprint feature in the inventory, and the process of fingerprint verification can be completed.
本发明实施例提供了一种指纹解锁的方法，首先在终端处于黑屏状态时，通过指纹传感器检测是否有指纹录入，当指纹传感器检测到有指纹录入时，触发指纹传感器采集指纹，并对采集到的指纹进行验证，若验证成功，则点亮屏幕，进行解锁。该方案实现了在终端处于黑屏状态时，只要触发指纹传感器就可以进行指纹验证，若验证成功就可以点亮屏幕，加快了通过使用指纹来点亮屏幕并解锁的时间，提升了用户体验。The embodiment of the invention provides a method for unlocking a fingerprint. First, when the terminal is in a black screen state, the fingerprint sensor detects whether there is fingerprint input. When the fingerprint sensor detects fingerprint input, the fingerprint sensor is triggered to collect the fingerprint, and the fingerprint is collected. The fingerprint is verified. If the verification is successful, the screen is illuminated and unlocked. The solution realizes that when the terminal is in a black screen state, the fingerprint verification can be performed only by triggering the fingerprint sensor. If the verification is successful, the screen can be illuminated, and the time for lighting the screen and unlocking by using the fingerprint is accelerated, thereby improving the user experience.
实施例二Embodiment 2
图2为本发明实施例二提供的指纹解锁的方法的流程图，本实施例以实施例一为基础，进行优化，包括：2 is a flowchart of a method for unlocking a fingerprint according to Embodiment 2 of the present invention. The present embodiment is optimized based on the first embodiment, and includes:
步骤210、将指纹识别进程设定为实时监控状态；Step 210: Set the fingerprint identification process to a real-time monitoring state;
由于指纹录入是随时都会通过指纹传感器录入的，所以为了让指纹识别进程随时检测指纹传感器是否有指纹录入，可以将指纹识别进程设定为实时监控状态，便于随时检测是否有指纹录入。Since the fingerprint input is entered by the fingerprint sensor at any time, in order to allow the fingerprint recognition process to detect whether the fingerprint sensor has fingerprint input at any time, the fingerprint recognition process can be set to a real-time monitoring state, so that it is convenient to detect whether there is fingerprint input at any time.
进一步的，将指纹识别进程设定为实时监控状态，可以包括：通过将指纹识别进程设定为守护进程，以将指纹识别进程设定为实时监控状态。Further, setting the fingerprint recognition process to the real-time monitoring state may include: setting the fingerprint recognition process to a real-time monitoring state by setting the fingerprint recognition process as a daemon process.
通过将指纹识别进程设定为守护进程可以实现将指纹识别进程设定为实时监控状态。守护进程是Linux中的后台服务进程，守护进程是一个生存期较长的进程，并且守护进程通常可以独立于控制终端并且周期性地执行某种任务或等待处理某些发生的事件。守护进程可以不受终端开关的影响，当终端被关闭时，守护进程不会关闭。因此将指纹识别进程作为守护进程可以实时监控是否有指纹录入，当有指纹录入时，可以直接进行指纹采集和对采集的指纹进行验证，节省指纹验证的时间，提升用户的体验。The fingerprint recognition process can be set to a real-time monitoring state by setting the fingerprint recognition process as a daemon. A daemon is a background service process in Linux. A daemon is a long-lived process, and a daemon can usually be independent of the controlling terminal and periodically perform certain tasks or wait for certain events to occur. The daemon can be unaffected by the terminal switch, and the daemon will not shut down when the terminal is shut down. Therefore, the fingerprint recognition process can be used as a daemon to monitor whether fingerprints are recorded in real time. When fingerprints are entered, fingerprints can be directly collected and the collected fingerprints can be verified, which saves time for fingerprint verification and improves user experience.
具体的，当按下电源键（power key）待机时，指纹识别进程处于低功耗等待状态；当指纹传感器检测到有指纹录入时，通知指纹识别进程，进行指纹验证。Specifically, when the power button is pressed (power Key) During standby, the fingerprint recognition process is in a low power standby state; when the fingerprint sensor detects fingerprint entry, it notifies the fingerprint recognition process to perform fingerprint verification.
步骤220、采用指纹识别进程通过指纹传感器检测是否有指纹录入；Step 220: Using a fingerprint identification process to detect whether a fingerprint is entered by using a fingerprint sensor;
在终端处于黑屏状态时，指纹传感器检测是否有录入指纹时，可以是采用指纹识别进程通过指纹传感器检测是否有指纹录入。When the fingerprint sensor detects whether there is a fingerprint input when the terminal is in a black screen state, the fingerprint identification process may be used to detect whether there is fingerprint input through the fingerprint sensor.
步骤230、当通过指纹传感器检测到有指纹录入时，触发指纹传感器采集指纹，并对采集到的指纹进行验证；Step 230: When fingerprint input is detected by the fingerprint sensor, the fingerprint sensor is triggered to collect the fingerprint, and the collected fingerprint is verified;
步骤240、若指纹验证成功，则点亮屏幕，并进行解锁。Step 240: If the fingerprint verification is successful, the screen is illuminated and unlocked.
具体的，通过将指纹识别进程设定为守护进程，以将指纹识别进程设定为实时监控状态。当手指触发指纹传感器时，Linux内核响应到中断信号，指纹识别进程立即开始验证指纹，如果指纹验证成功，则点亮屏幕，并进行解锁。经测试比现有技术中运用指纹点亮屏幕的时间节省了大约100-200ms。Specifically, the fingerprint recognition process is set to a real-time monitoring state by setting the fingerprint recognition process as a daemon process. When the finger triggers the fingerprint sensor, the Linux kernel responds to the interrupt signal, and the fingerprint recognition process immediately starts verifying the fingerprint. If the fingerprint verification is successful, the screen is illuminated and unlocked. It has been tested to save about 100-200 ms compared to the prior art using fingerprints to illuminate the screen.
本实施例的技术方案通过将指纹识别进程设定为实时监控状态，在终端处于黑屏状态时，当手指触发指纹传感器时，唤醒指纹识别进程进行指纹验证，若验证成功就可以点亮屏幕，比现有技术中运用指纹来点亮屏幕的时间短，提升用户体验。The technical solution of the embodiment sets the fingerprint identification process to the real-time monitoring state. When the terminal is in the black screen state, when the finger triggers the fingerprint sensor, the fingerprint recognition process is awakened to perform fingerprint verification. If the verification succeeds, the screen may be illuminated. In the prior art, the use of fingerprints to light the screen for a short period of time enhances the user experience.
实施例三Embodiment 3
图3为本发明实施例三提供的指纹解锁的方法的流程图，本实施例以实施例一为基础，进行优化，包括：FIG. 3 is a flowchart of a method for unlocking a fingerprint according to Embodiment 3 of the present invention. The present embodiment is optimized based on the first embodiment, and includes:
步骤310、在终端处于黑屏状态时，通过指纹传感器检测是否有指纹录入；Step 310: When the terminal is in a black screen state, detecting whether there is fingerprint input by using a fingerprint sensor;
步骤320、当通过指纹传感器检测到有指纹录入时，触发指纹传感器采集指纹，并对采集到的指纹进行验证；Step 320: When fingerprint input is detected by the fingerprint sensor, the fingerprint sensor is triggered to collect the fingerprint, and the collected fingerprint is verified;
步骤330、若指纹验证成功，则点亮屏幕，并进行解锁。Step 330: If the fingerprint verification is successful, the screen is illuminated and unlocked.
进一步的，步骤340、若指纹验证失败，则以设定提醒方式提醒用户。Further, in step 340, if the fingerprint verification fails, the user is reminded by setting a reminder manner.
其中，所述设定提醒方式优选可以是震动和/或响铃。The setting reminding mode may preferably be vibration and/or ringing.
这样设置便于当指纹验证失败时，用户可以得到提醒，用户可以用正确的指纹重新进行指纹验证，或者直接放弃指纹验证。This setting makes it easy for the user to get a reminder when the fingerprint verification fails. The user can re-find the fingerprint with the correct fingerprint or directly abandon the fingerprint verification.
本实施例的技术方案在终端处于黑屏状态时，通过检测是否有指纹输入，当指纹传感器检测到有指纹录入时，可以直接进行指纹采集和对采集的指纹进行验证，如果验证成功，则点亮屏幕，并进行解锁，如果验证失败，则以设定的方式通知用户，让用户知晓，这样可以在验证成功时节省时间，在验证失败后发出提醒，提升用户的体验。The technical solution of the embodiment is to detect whether there is fingerprint input when the terminal is in a black screen state. When the fingerprint sensor detects fingerprint input, the fingerprint may be directly collected and verified, and if the verification succeeds, the LED is lit. The screen is unlocked. If the verification fails, the user is notified in a set manner to let the user know. This saves time when the verification is successful, and sends a reminder after the verification fails to enhance the user experience.
