Although the LTE system is described as an example, it should be understood by those skilled in the art that the present invention is not limited to the LTE system, but may also be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems.
Based on the hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are provided.
Referring to fig. 3, fig. 3 is a flowchart illustrating steps of a camera rights management method according to an embodiment of the present invention, where the method is applied to a mobile terminal, and as shown in fig. 3, the method includes:
step 301, detecting whether an application program calls a camera of the mobile terminal.
In this step, the mobile terminal detects whether an application program calls the camera of the mobile terminal, and if the application program calls the camera of the mobile terminal, step 302 is executed; and if the application program does not call the camera of the mobile terminal, the process is ended. It is understood that the application mentioned in this step refers to an application having a camera call authority. The mobile terminal can detect whether an application program calls a camera of the mobile terminal at preset time intervals.
Step 302, judging whether the application program illegally calls the camera.
In this step, if the application program calls the camera of the mobile terminal, the mobile terminal further determines whether the application program illegally calls the camera, and if the application program illegally calls the camera, step 303 is executed; on the contrary, if the application program calls the camera normally, the process is ended. The manner of judging whether the application program illegally calls the camera by the mobile terminal may be specifically that whether the mobile terminal displays a preview interface of the camera within a first preset time after the application program calls the camera is detected. Or whether a trigger operation is received within a second preset time before the application program calls the camera can be detected.
When the mobile terminal judges whether the application program illegally calls the camera by detecting whether the mobile terminal displays a preview interface of the camera within a first preset time after the application program calls the camera, considering that the application program normally calls the camera, a preview interface of image data collected by the camera needs to be displayed on a user interface of the mobile terminal, for example, the camera is called to perform two-dimensional scanning or the camera is called to take a picture. If the mobile terminal has a preview interface for displaying the camera within a first preset time after the application calls the camera, indicating that the application calls the camera normally; on the contrary, if the application program calls the camera within a first preset time, the mobile terminal does not display the preview interface of the camera, and the mobile terminal determines that the application program illegally calls the camera.
Specifically, the mobile terminal may start a countdown (that is, a countdown with a start duration being a first preset time, for example, 10 seconds) after detecting that the application calls the camera, then detect whether the mobile terminal displays a preview interface of the camera every certain time (for example, 1 second), and if it is detected that the mobile terminal displays the preview interface of the camera before the countdown is finished, the mobile terminal terminates the countdown and determines that the application legally calls the camera; and if the mobile terminal is not detected to display the preview interface of the camera until the countdown is finished, the mobile terminal determines that the application program illegally calls the camera.
The method for the mobile terminal to detect whether the application program calls the camera within a first preset time after the application program calls the camera may specifically include: detecting whether the mobile terminal uses a preset layer to display image data acquired by the camera within a first preset time after the application program calls the camera; if the application program calls the camera within a first preset time, the mobile terminal does not use a preset image layer to display the image data acquired by the camera, and it is determined that the mobile terminal does not display a preview interface of the camera. It can be understood that, when the mobile terminal displays the preview interface of the camera, a Surface View layer is used to display image data acquired from the camera.
When the mobile terminal judges whether the application program illegally calls the camera by detecting whether a trigger operation is received within a second preset time before the application program calls the camera, under the condition that the application program normally calls the camera, a user usually executes some trigger operations on the application program, and the application program responds to the trigger operations to call the camera. If the triggering operation is not received within a second preset time before the application program calls the camera, the application program may call the camera autonomously, and the mobile terminal determines that the application program calls the camera illegally. In some embodiments of the present invention, considering that an application may close a camera within a very short time after the camera is called when the camera is illegally called, the mobile terminal may further determine whether the application illegally calls the camera according to a call duration of the application calling the camera. Specifically, if a trigger operation is not received within a second preset time before the application calls the camera, the mobile terminal detects whether the camera is closed within a third preset time (for example, 2 seconds) after the application calls the camera, and if the camera is closed within the third preset time after the application calls the camera, the mobile terminal determines that the application illegally calls the camera.
It should be noted that, in some embodiments of the present invention, the mobile terminal may also determine whether the application program illegally calls the camera together with the two manners, that is, when the application program calls the camera within a first preset time, the mobile terminal does not display a preview interface of the camera, and when the application program does not receive a trigger operation within a second preset time before calling the camera, the mobile terminal determines that the application program illegally calls the camera.
And step 303, controlling the mobile terminal to send a first prompt message or close the calling authority of the application program to the camera.
In this step, if the application program illegally calls the camera, the mobile terminal controls the mobile terminal to send a first prompt message or close the calling authority of the application program to the camera. The first prompt message may include one or more of sound, light, and vibration, and is used to prompt the user that the application program illegally invokes the camera, so that the user may decide whether to close the invocation permission of the application program on the camera according to the first prompt message.
In some embodiments of the present invention, if the application program illegally calls the camera, the mobile terminal does not directly control the mobile terminal to send a first prompt message or close the call permission of the application program to the camera, but records the number of times of illegal call of the application program illegally calling the camera, and if the number of times of illegal call of the application program illegally calling the camera is greater than a first preset number (for example, 3 times), controls the mobile terminal to send a first prompt message or close the call permission of the application program to the camera.
In other embodiments of the present invention, if the camera is illegally called by the application program, the mobile terminal sends a first prompt message and records the number of times of illegal calling of the camera by the application program, and if the number of times of illegal calling of the camera by the application program is greater than a second preset number of times, the right of calling the camera by the application program is closed. The second preset number may be the same number as the first preset number, or may be a number different from the first preset number, which is not specifically limited in the present invention. Further, after the calling authority of the application program to the camera is closed, the mobile terminal may further send a second prompt message for prompting the user that the camera calling authority of the application program is closed.
In this embodiment, the camera right management method detects whether an application program calls a camera of the mobile terminal; if the application program calls the camera of the mobile terminal, judging whether the application program illegally calls the camera; and if the application program illegally calls the camera, controlling the mobile terminal to send a first prompt message or closing the calling authority of the application program to the camera. The camera authority management method provided by the invention judges whether the application program illegally calls the camera when detecting that the application program calls the camera, and sends out a prompt message or closes the calling authority of the application program to the camera when the application program illegally calls the camera, so that the camera can be effectively prevented from being illegally called by the application program, and the privacy information of a user is prevented from being leaked.

Referring to fig. 4, fig. 4 is a schematic flowchart of another camera rights management method provided in the embodiment of the present invention, and as shown in fig. 4, the method includes:
step 401, detecting whether the application program calls a camera of the mobile terminal.
In this step, the mobile terminal detects whether an application program calls the camera of the mobile terminal, and if the application program calls the camera of the mobile terminal, step 402 is executed; and if the application program does not call the camera of the mobile terminal, the process is ended. This step 401 is the same as step 301 in the embodiment shown in fig. 3 of the present invention, and is not described herein again.
Step 402, detecting whether the mobile terminal displays a preview interface of the camera within a first preset time after the application program calls the camera.
In this step, if the application program calls the camera, it is detected whether the mobile terminal displays a preview interface of the camera within a first preset time after the application program calls the camera. In this embodiment, the mobile terminal determines whether the application program illegally calls the camera by detecting whether the mobile terminal displays a preview interface of the camera within a first preset time after the application program calls the camera. If the application program illegally calls the camera, executing step 403; on the contrary, if the application program calls the camera normally, the process is ended.
In consideration of the situation that the application program calls the camera normally, a preview interface of image data acquired by the camera needs to be displayed on a user interface of the mobile terminal, for example, the camera is called to perform two-dimensional scanning or the camera is called to take a picture. If the mobile terminal has a preview interface for displaying the camera within a first preset time after the application calls the camera, indicating that the application calls the camera normally; on the contrary, if the application program calls the camera within a first preset time, the mobile terminal does not display the preview interface of the camera, and the mobile terminal determines that the application program illegally calls the camera.
The method for the mobile terminal to detect whether the application program calls the camera within a first preset time after the application program calls the camera may specifically include: detecting whether the mobile terminal uses a preset layer to display image data acquired by the camera within a first preset time after the application program calls the camera; if the application program calls the camera within a first preset time, the mobile terminal does not use a preset image layer to display the image data acquired by the camera, and it is determined that the mobile terminal does not display a preview interface of the camera. It can be understood that, when the mobile terminal displays the preview interface of the camera, a Surface View layer is used to display image data acquired from the camera.
And step 403, controlling the mobile terminal to send a first prompt message or close the calling authority of the application program to the camera.
In this step, if the application program calls the camera within a first preset time, the mobile terminal does not display a preview interface of the camera, and controls the mobile terminal to send a first prompt message or close the calling authority of the application program to the camera. This step 403 is the same as step 303 in the embodiment of fig. 3 of the present invention, and is not described herein again.
Optionally, the detecting whether the mobile terminal displays the preview interface of the camera within a first preset time after the application program calls the camera includes:
detecting whether the mobile terminal uses a preset layer to display image data acquired by the camera within a first preset time after the application program calls the camera;
if the application program calls the camera within a first preset time, the mobile terminal does not use a preset image layer to display the image data acquired by the camera, and it is determined that the mobile terminal does not display a preview interface of the camera.
Referring to fig. 5, fig. 5 is a schematic flowchart of another camera rights management method provided in an embodiment of the present invention, and as shown in fig. 5, the method includes:
and step 501, detecting whether the application program calls the camera of the mobile terminal.
In this step, the mobile terminal detects whether an application program calls a camera of the mobile terminal, and if the application program calls the camera of the mobile terminal, step 502 is executed; and if the application program does not call the camera of the mobile terminal, the process is ended. This step 501 is the same as step 301 in the embodiment shown in fig. 3 of the present invention, and is not described here again.
Step 502, detecting whether a trigger operation is received within a second preset time before the application program calls the camera.
In this step, if the application program calls the camera, the mobile terminal detects whether a trigger operation is received within a second preset time before the application program calls the camera. In this step, the mobile terminal determines whether the application program illegally calls the camera by detecting whether a trigger operation is received within a second preset time before the application program calls the camera. If the application program illegally calls the camera, executing step 503; on the contrary, if the application program calls the camera normally, the process is ended.
Considering that an application normally calls the camera, it is common that a user performs some triggering operation on the application, and the application calls the camera in response to the triggering operation. If the triggering operation is not received within a second preset time before the application program calls the camera, the application program may call the camera autonomously, and the mobile terminal determines that the application program calls the camera illegally. In some embodiments of the present invention, considering that an application may close a camera within a very short time after the camera is called when the camera is illegally called, the mobile terminal may further determine whether the application illegally calls the camera according to a call duration of the application calling the camera. Specifically, if a trigger operation is not received within a second preset time before the application calls the camera, the mobile terminal detects whether the camera is closed within a third preset time (for example, 2 seconds) after the application calls the camera, and if the camera is closed within the third preset time after the application calls the camera, the mobile terminal determines that the application illegally calls the camera.
Step 503, controlling the mobile terminal to send a first prompt message or close the calling authority of the application program to the camera.
In this step, if the triggering operation is not received within a second preset time before the application program calls the camera, the mobile terminal is controlled to send a first prompt message or close the calling authority of the application program to the camera. This step 503 is the same as step 303 in the embodiment shown in fig. 3 of the present invention, and is not described here again.
Optionally, the determining that the application program illegally calls the camera if the application program does not receive the trigger operation within a second preset time before the application program calls the camera includes:
if the triggering operation is not received within a second preset time before the application program calls the camera, detecting whether the camera is closed within a third preset time after the application program calls the camera;
and if the camera is closed within a third preset time after the application program calls the camera, determining that the application program illegally calls the camera.
