Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the invention relates to a method for setting a screen locking password, which monitors the time of a terminal by using a time monitoring service; the time monitoring service is restarted under the condition that the background running state is abnormal; and if the change of the monitored time meets the preset condition, updating the currently set screen locking password based on the monitored time. Thereby improving the security and stability of password setting. The implementation details of the lock screen password setting method of the present embodiment are specifically described below, and the following description is only provided for the convenience of understanding, and is not necessary for implementing the present embodiment.
As shown in fig. 1, the method for setting a screen locking password according to the embodiment includes:
Specifically, the time listening service is created and configured in advance so as to be directly called and used when the time listening service is utilized. When creating and configuring the time monitoring service, firstly, a subclass of an inheritance service can be defined, and secondly, the time monitoring service TimeLockService can be configured in a manifest file (android manifest.
And starting the time monitoring service by using a startService () function, and running in a background after the time monitoring service is started to continuously monitor the time of the terminal.
The time monitoring service is used to monitor the time of the terminal, and the monitoring may be implemented by using a second device management receiver (TimeLockReceiver) registered in the time monitoring service. Specifically, a second device management receiver (TimeLockReceiver) is dynamically registered in a TimeLockService, and the second device management receiver may receive a time broadcast sent by a terminal system when the time of the terminal changes, that is, the second device management receiver represents that the time of the terminal changes when receiving the time broadcast, and may calculate the time of the terminal after the change (the time for receiving the time broadcast) according to the number of times the second device management receiver receives the time broadcast when determining the initial time of the terminal and the time interval for sending the time broadcast by the terminal system.
In addition, in practical application, a time monitoring service (TimeLockService) needs to be resident in the background, so that the time monitoring service can continuously monitor the change of time, the screen locking password can be timely updated, and the stability and reliability of the screen locking password are improved.
In order to keep the time monitoring service resident in the background, the background running state of the time monitoring service can be monitored by using other services, or the broadcast receiver is used for receiving and monitoring the broadcast of the background running state of the time monitoring service. Taking the background running state of the monitoring service monitored by the broadcast monitoring time as an example, the monitoring process is specifically described below. After the time monitoring service is started, if the running state of the time monitoring service is normal, the broadcasting which runs normally is sent in a preset period. If the broadcast receiver receives the broadcast which runs normally, the running state of the time monitoring service background is normal. If the broadcast receiver does not receive the broadcast sent by the time monitoring service after the preset time, the time monitoring service is abnormal in the background running state and is cleared by the system or the antivirus software. If the broadcast receiver receives the broadcast with abnormal operation, the background operation state of the time monitoring service is also abnormal. When the background running state of the time monitoring service is abnormal, the time monitoring service is controlled to restart, for example, the time monitoring service can be awakened by a broadcast receiver. The broadcast receiver for monitoring the background running state of the time monitoring service can be a newly added first equipment management receiver registered in the time monitoring service, and can also monitor the time monitoring service by utilizing a second equipment management receiver registered in the time monitoring service, so that the utilization rate of the second equipment management receiver is improved.
In addition, in practical application, the time monitoring service may be used to monitor the device management receiver for monitoring the background running state thereof, that is, the time monitoring service and the device management receiver monitor the background running state mutually. This can be done after one of the time listening service and device management receiver is cleared by the antivirus program while the other is running, which can be awakened immediately, and the awakened time listening service or device management receiver will not be cleared again within a certain time. Since one of the time monitoring service and the equipment management receiver is in a running state, the time monitoring service and the equipment management receiver can stably realize that the time monitoring service is resident in a background.
And 102, updating the currently set screen locking password based on the monitored time when the change of the monitored time meets the preset condition.
Specifically, when the time of the terminal is monitored, the time monitoring service may be used to monitor that the time of the terminal changes. And judging whether the change of the time meets a preset condition, wherein the preset condition can be that whether the change of the time meets a preset threshold value, and if the change of the time is 1 minute, the preset condition is met.
In order to realize that the monitored Time change meets the preset condition, a Time filter Time _ Tick can be used for setting a timing task, and the Time filter Time _ Tick can be used for realizing the transmission of Time broadcast in a preset period. For example, if the preset condition is set that the Time change is 1 minute, the timing task may be set to send a broadcast every 1 minute, and then the Time monitoring service may receive the Time broadcast sent by using the Time filter Time _ Tick, that is, the Time change satisfies the preset condition.
And after the change of the terminal time meets a preset condition, updating the currently set screen locking password. Specifically, the screen locking password can be updated according to a preset password setting rule and the monitored current time, or the monitored current time is directly used as the updated screen locking password.
The set password setting rule may be as follows: and converting the monitored time into a digital sequence form, changing the arrangement sequence of the digital sequence, taking the changed digital sequence as a target screen locking password, and finally replacing the current screen locking password by using the target screen locking password. For example, if the password setting rule specifies that the number sequence is adjusted from 1234 to 4321, the target lock screen password may be set to 0311 when the monitored current time is 11: 30.
The set password setting rule can also be that the target screen locking password with four digits is obtained through recalculation according to a preset formula and monitoring time. For example, if the predetermined formula is N +2, N is the number of each digit, i.e., the monitored time is converted into a form of a digital sequence, 2 is added to the number of each digit, and if the number of the digit after calculation is greater than ten, the number of the digit is taken as the number of the digit after calculation. Assume that the time of monitoring is 11:30, then the target lock screen password may be set to 3352. In practical application, a user can set password setting rules and formulas according to the self condition so as to improve the password security and avoid the problem that the user forgets the password to cause abnormal unlocking.
Compared with the prior art, the method and the device have the advantages that the time of the terminal is monitored through the time monitoring service resident in the background, the current screen locking password is changed when the change of the time meets the preset condition, the modified screen locking password is related to the current time, and the security of dynamically updating the screen locking password is higher than that of a static password. In addition, the time monitoring service can be automatically restarted if the running state of the time monitoring service is abnormal in the background, so that the time monitoring service can be kept in the running state in the background, real-time monitoring time change is guaranteed, the screen locking password can be timely updated based on the current time, and the stability and the reliability of updating the screen locking password are improved.
The second embodiment of the present invention relates to a method for setting a screen locking password, and in the second embodiment of the present invention, the second device management receiver is statically registered in a manifest file, so as to enhance the security and stability of the second device management receiver.
As shown in fig. 2, the method for setting a screen locking password according to this embodiment includes:
Specifically, the TimeLockReceiver is statically registered to ensure the stability of the second device manager and avoid being cleared by the terminal system.
Specifically, the set calculation formula can be complex or simple, the monitored time is calculated by using the calculation formula, and the calculated result is used as the target screen locking password. The obtained target screen locking password is kept to be four-digit, so that the target screen locking password can be dynamically changed based on the original screen locking interface.
Specifically, after the application is started, the user creates a device manager according to the prompt, and the subsequent screen locking password modification operation is taken over by the device manager.
The device manager detects whether a screen locking password is set at the current terminal, if so, the screen locking password is modified according to the current time and the set calculation formula, and if not, the current time and the target screen locking password calculated by the calculation formula are directly set as the current screen locking password.
The device manager sets the password and simultaneously starts a time monitoring service TimeLockservice, and the service resides in the background.
The second device manager TimeLockReceiver is dynamically registered again in service to listen for the Time broadcast sent by the filter timetick to listen for changes in Time. The filter Time _ Tick is registered with the second device manager by dynamic registration when the Time filter is created.
And step 206, modifying the screen locking password.
And monitoring the time change, sending a request to an equipment manager, updating the current screen locking password by the equipment manager, and replacing the current screen locking password by using the calculated target screen locking password.
When the user unlocks, the correct result of calculation is input in the input box through the current time and a preset calculation formula, and then the unlocking can be realized. If the input times exceed the preset times, the user is prohibited from inputting again, and the user is allowed to input again after waiting for a period of time.
In this embodiment, the updating process of the screen locking password is wholly described, and the second device management receiver is statically registered in the manifest file in advance, so that the security and the stability of the second device management receiver are ensured, and the second device management receiver is prevented from being cleared by software.
