Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
Fig. 1 is a flowchart of a method for detecting working abnormality of a fingerprint module according to an embodiment of the present invention, where an execution subject of the method may be a terminal device with a fingerprint identification function, such as a mobile phone, a personal computer, or the like, or an apparatus integrated in the terminal or the device. As shown in fig. 1, the method for detecting the abnormal operation of the fingerprint module includes the following steps:
s110, extracting the log data of the fingerprint pressing interrupt signal in the log file. The fingerprint pressing interrupt signal is generated when the fingerprint module identifies the fingerprint pressing operation and is reported to the hardware abstraction layer HAL.
In the existing terminal with fingerprint identification, after a fingerprint module located at the bottom layer of terminal hardware identifies a fingerprint pressing operation, an interrupt signal generated by identification is usually directly transmitted to a corresponding bottom layer driver or a driver circuit, and is not reported to a system layer of a terminal system. When the fingerprint module is abnormal and cannot perform fingerprint identification, no fingerprint is pressed to interrupt signals to subsequent driving equipment to execute and complete subsequent operation. Because above-mentioned operation all takes place at the chip layer of system, the unable perception of system's aspect, consequently, when carrying out at the terminal and accomplish through fingerprint identification operation failures such as terminal unblock, APP password affirmation, the system's aspect can not know, and it is unusual to appear in the fingerprint module, still the follow-up drive that it caused appears when operating.
The embodiment senses and transmits the behavior of the fingerprint module for identifying the fingerprint pressing operation by means of a Hardware Abstraction Layer (HAL) in the terminal system, wherein the Hardware Abstraction Layer is arranged at the bottom Layer of a chip and an intermediate Layer of a system Layer.
For example, a functional unit that reports a fingerprint pressing interrupt signal to the hardware abstraction layer HAL may be added to the existing fingerprint module, and the functional unit is connected to a read thread of the fingerprint pressing interrupt signal located in the HAL layer through a netlink interface, so as to report the generated fingerprint pressing interrupt signal to the fingerprint module when the fingerprint module identifies a fingerprint pressing operation. Meanwhile, a reading thread for reading the fingerprint pressing operation is additionally arranged on the HAL layer, and the reading thread can periodically read the fingerprint pressing interrupt signal reported to the HAL layer when the fingerprint pressing operation is identified by the fingerprint module. And in the process that the reading thread receives the fingerprint pressing interrupt signal reported by the fingerprint reading module, the system layer can normally record the behavior of the reading thread in the HAL layer, and generate corresponding log data to be stored in a log file in the terminal. By searching and extracting the log data generated by reporting the fingerprint pressing interrupt signal to the hardware abstraction layer HAL when the fingerprint module in the terminal identifies the fingerprint pressing operation in the log file, the behavior of the fingerprint module generating the interrupt signal can be known.
And S120, determining whether the fingerprint module is abnormal or not according to the extracted log data.
Specifically, according to whether log data generated by reporting a fingerprint pressing interrupt signal to the hardware abstraction layer HAL when the fingerprint module in the terminal identifies a fingerprint pressing operation is included in the log file, whether the fingerprint module successfully identifies the fingerprint pressing operation performed on the terminal or not and a correct interrupt signal generated by the fingerprint module can be known, and whether the fingerprint module is abnormal or not is further determined.
For example, if the log data contains data of the fingerprint pressing interrupt signal, the fingerprint pressing operation on the terminal can be normally identified by the fingerprint characterization module, so that the fingerprint module is determined to be abnormal;
if the log data does not contain the data of the fingerprint pressing interrupt signal, the fingerprint pressing operation on the terminal cannot be normally identified by the fingerprint module, and therefore the fingerprint module is determined to be abnormal.
Furthermore, if the extracted log data contains data of the fingerprint pressing interrupt signal and the fingerprint module identifies the terminal operation abnormality caused after the fingerprint pressing operation, it is determined that the equipment executing the terminal operation is abnormal.
For example, when a terminal is detected to perform fingerprint unlocking operation, if a fingerprint module is extracted from a log file in the terminal to identify fingerprint pressing operation and report a fingerprint pressing interrupt signal to log data generated by a hardware abstraction layer HAL, but the terminal is not successfully unlocked, it indicates that a module unit executing a terminal unlocking function is abnormal and cannot normally operate.
The method for detecting the working abnormity of the fingerprint module comprises the steps of reporting a fingerprint pressing interrupt signal to a hardware abstraction layer HAL (hardware abstraction layer) by detecting the behavior of the fingerprint module in a terminal when the fingerprint module identifies the fingerprint pressing operation, and extracting log data correspondingly generated by the behavior from a log file in the terminal; then, whether the fingerprint pressing operation is really identified by the fingerprint module is judged through the extracted log data, and whether the fingerprint module is abnormal is further judged.
Example two
Fig. 2 is a flowchart of another method for detecting a working anomaly of a fingerprint module according to an embodiment of the present invention, which can be regarded as a specific implementation manner of the embodiment of the method shown in fig. 1. As shown in fig. 2, the method for detecting abnormal operation of the fingerprint module further includes the following steps based on the embodiment of the method shown in fig. 1:
s210, monitoring a fingerprint pressing interrupt signal reported to the hardware abstraction layer HAL by the fingerprint module.
Specifically, a monitoring function unit for monitoring a read thread that reads a fingerprint pressing interrupt signal in the HAL layer may be disposed in the user system layer, and when the read thread receives the fingerprint pressing interrupt signal, the interrupt signal is reported to the monitoring function unit for subsequent processing.
And S220, if the fingerprint pressing interruption signal is monitored, determining that the fingerprint module is not abnormal.
If the monitoring function unit receives the fingerprint pressing interrupt signal, the characterization fingerprint module can normally perform fingerprint identification and generate the interrupt signal, and the system layer senses and determines that the fingerprint module is not abnormal.
In an actual application scenario, if the terminal system layer does not monitor the fingerprint pressing interrupt signal, step S110 is executed, and a processing step of extracting log data of the fingerprint pressing interrupt signal is performed in a log file. .
Specifically, if the monitoring function unit does not receive the fingerprint pressing interrupt signal, the characterization fingerprint module may be abnormal, and cannot perform fingerprint identification, and thus cannot generate the interrupt signal; or, the fingerprint pressing interrupt signal cannot be normally reported to the system layer when the read thread is abnormal. Based on the two uncertain factors, the system layer cannot sense whether the fingerprint module is abnormal or not. At this time, whether the fingerprint module has abnormal operation can be finally detected by continuing to execute the steps of the embodiment of the method shown in fig. 1.
Before the method of the embodiment shown in fig. 1 is executed, a fingerprint pressing interrupt signal reported to a hardware abstraction layer HAL when a fingerprint pressing operation is identified by a monitoring fingerprint module; it is then determined whether it is necessary to perform the contents of the embodiment of the method shown in fig. 1 based on the monitoring result. If the fingerprint pressing interruption signal is monitored, the fingerprint module is proved to work normally, and the working behavior of the fingerprint module is not required to be judged by extracting log data, so that the processing step of judging whether the fingerprint module works abnormally by extracting the log data is saved, and the flow of the method is simplified.
EXAMPLE III
Fig. 3 is a flowchart of another method for detecting a fingerprint module working anomaly according to an embodiment of the present invention, which can be regarded as another specific implementation manner after the method embodiments shown in fig. 1 or fig. 1 and fig. 2 are combined. As shown in fig. 3, the method for detecting the abnormal operation of the fingerprint module based on the embodiment of the method shown in fig. 1 includes the following steps:
s310, in the log file, extracting the log data of all the interrupt signals reported to the hardware abstraction layer HAL by the fingerprint module.
The log file stored in the terminal only contains simple behavior identification information for marking the terminal behavior, and the identification information also comprises behavior identification information for reporting an interrupt signal when the fingerprint module identifies the fingerprint pressing operation. In this embodiment, when the fingerprint pressing interrupt signal is extracted from the log file, the log data generated corresponding to all the interrupt signals reported by the fingerprint module in the detection process is extracted, and then the subsequent identification is performed.
And S320, calculating and identifying the log data of all the interrupt signals according to a preset algorithm to obtain the event content corresponding to each interrupt signal.
After extracting the log data of all the interrupt signals reported by the fingerprint module, calculating and identifying the identifiers representing the types of the interrupt signals according to a preset algorithm, thereby determining the specific category of each interrupt signal, namely the event content corresponding to the interrupt signal. For example, the interrupt signal generated for fingerprint recognition may be defined as an image capture interrupt signal, and further according to two processes of pressing and lifting the finger, the corresponding interrupt signals include an interrupt signal generated by pressing the fingerprint and an interrupt signal generated by lifting the fingerprint.
The log data corresponding to the terminal signal is calculated by a pre-established algorithm and the event content is restored to the prior art, which is not described in detail in this embodiment.
S330, determining an interrupt signal corresponding to the content of the event of the fingerprint pressing operation identified by the fingerprint module as a fingerprint pressing interrupt signal.
And after the extracted log data of all the interrupt signals are calculated and identified according to a preset algorithm to obtain event contents corresponding to all the interrupt signals, determining the event contents as interrupt signals generated by pressing the fingerprint and interrupt signals generated by lifting the fingerprint as the fingerprint pressing interrupt signals.
The steps S310 to S330 can be regarded as the refinement step of the step S110.
And S340, determining whether the fingerprint module is abnormal or not according to the extracted log data. Step S340 is similar to the foregoing step S120.
In addition, when the fingerprint module is judged to be abnormal, although log data of the fingerprint pressing interrupt signal exists, the fingerprint pressing operation behavior reflected by the log data does not accord with the actual pressing operation behavior. For example, the sequence of fingerprint pressing and fingerprint lifting of the detector is inconsistent with the operation behaviors of fingerprint pressing and fingerprint lifting reflected by log data. In this case, it is also determined that the fingerprint module is malfunctioning.
Therefore, after step S340, especially after step S230, the following steps may be further performed to further determine whether the fingerprint module is abnormal.
And S350, outputting a detection result whether the fingerprint module is abnormal or not.
The monitoring result can include a result identifier for primarily judging whether the fingerprint module is abnormal or not, and can also output information data related to the detection process or the result.
For example, as a specific way of outputting a detection result of whether an abnormality occurs in the fingerprint module, log data of the fingerprint pressing interrupt signal may be printed and/or displayed while outputting the result identification.
Specifically, an output software interface for displaying the abnormal detection result of the fingerprint module can be set in the system layer of the terminal, and the abnormal detection result can be displayed through the display function of the terminal. Meanwhile, whether the fingerprint module is judged to be abnormal preliminarily or not, the log data corresponding to the fingerprint pressing interrupt signal reported by the fingerprint module can be printed and/or displayed from a log file output by the terminal, so that a detector can perform subsequent analysis and processing, and whether the fingerprint module is abnormal or not is judged further.
According to the method for detecting the working abnormity of the fingerprint module, which is provided by the embodiment of the invention, on the basis of the embodiment of the method, the step of extracting the log data of the fingerprint module reporting the fingerprint pressing interruption signal is refined. Meanwhile, after the result of whether the fingerprint module is abnormal is preliminarily obtained, the corresponding log data is printed and/or displayed so that a detector can further judge whether the fingerprint module is abnormal, and the accuracy of the detection result is improved.
