The prior art mainly prevents that private data from revealing through setting up the anti-peeping membrane on portable mobile terminal, the anti-peeping membrane has adopted superfine shutter structure, can make the scope that the light reflection of penetrating into the anti-peeping membrane goes out diminish, however this kind of mode can only prevent that other people outside certain angle range from seeing the content that the display screen shows, consequently, the mode that sets up the anti-peeping membrane among the prior art can make portable mobile terminal be in the anti-peeping mode always, portable mobile terminal can't normally show.
In view of this, the present application provides a data processing method, which can be executed by a terminal, where the terminal may be, for example, a mobile phone, a personal computer, a smart watch, a tablet computer, or the like. The following describes application scenarios related to embodiments of the present application.
Referring to fig. 1A, for an application scenario schematic diagram of a data processing method provided in the embodiment of the present application, or may be understood as a structural example diagram of a terminal, the terminal 110 includes a camera 120 and a display 130. The camera 120 may be a front camera or a rear camera.
In a possible embodiment, the display 130 may be a display with a color-changing function, and in order to more clearly illustrate the structure of the display 130, the following is a schematic partial cross-sectional view of the display provided in the embodiment of the present application shown in fig. 1B, and the possible cross-sectional structure of the display 130 is exemplified:
the display screen 130 comprises a display module 140 and a color-changing film layer 150, wherein the color-changing film layer 150 is arranged on the display module 140, and the term "upper" means that the side of the display screen 130 which is relatively closer to a user is viewed by the user. The color-changing thin film layer 150 may be, for example, electrochromic glass or thermochromic glass, wherein the electrochromic glass may undergo reversible changes in color and transparency under the action of an applied electric field, and the thermochromic glass may undergo reversible changes in color and transparency under the control of an applied temperature. The display module 140 refers to various components of the display 130 required for normal display, and is not described herein.
The terminal 110 responds to a triggering operation of a user on target data, the camera 120 starts to detect whether an unauthorized user exists in a camera shooting range, and if the unauthorized user exists and the distance between the terminal 110 and the unauthorized user is smaller than a preset threshold value, the display screen 130 is switched to a data protection mode, so that the unauthorized user cannot view contents displayed on the display screen 130 from any angle, and data is prevented from being peeped. The process of entering the data protection mode for the specific display screen 130 will be described below.
The terminal 110 may execute the data processing method according to the embodiment of the present application at any time, or, considering that a user may not want to be interfered by the data protection mode, in this embodiment of the present application, the terminal 110 does not execute the data processing method according to the embodiment of the present application in response to the closing operation of the data protection mode, and the terminal 110 executes the data processing method according to the embodiment of the present application in response to the opening operation of the data protection mode. For example, a user opens a particular application in terminal 110 in which a data protection mode may be turned on or off. The terminal 110 may automatically turn on the data protection mode when the user does not make any setting, i.e., by default.
Taking the application scenario discussed in fig. 1A as an example, when the data protection mode is turned on, a data processing method related to the embodiment of the present application is described below. Referring to fig. 2, a flowchart of a data processing method according to an embodiment of the present application is shown, where the method includes:
s210, responding to the trigger operation of the target data, and detecting whether an unauthorized user exists in the shooting range of the terminal.
The target data referred to in the present application is data that needs to be protected and is set by a user in advance, and the type of the target data may be one or more of an application, a photo, a video, a file, and a folder. The trigger operation includes one or more of an open operation, a view operation, and an edit operation, the open operation includes a user clicking an application, a file, etc., the view operation includes a user browsing a video, a photo, etc., the edit operation includes a user inputting information on a chat interface, inputting a password on a payment interface, etc. The terminal 110 may add or delete target data in response to a setting operation of the target data by the user, for example, the user opens a specific application in the terminal 110 in which the target data may be added or deleted.
In response to a trigger operation performed by a user on target data, the terminal 110 may detect whether an unauthorized user is present within a camera range of the terminal 110 through a face image matching technique to determine whether to turn on a data protection mode. The unauthorized user is a user not in the authorized user list, and the authorized user is a user which is preset by the user and can view the target data. The terminal 110 may have one or more face images of authorized users pre-stored therein, may be at least one face image of authorized users obtained by the terminal 110 in response to a setting operation of the user, or the terminal 110 may automatically set the face image of authorized users, for example, the terminal 110 may automatically set contacts in various social applications stored by the user as authorized users, and may also capture and store the face image of at least one contact from the social applications. Further, the terminal 110 may add or delete the stored face image of the authorized user in response to a setting operation of the face image of the authorized user by the user, for example, the user opens a specific application in the terminal 110 in which the face image of the authorized person may be added or deleted.
Specifically, when the terminal 110 detects that the user triggers the target data, for example, the terminal 110 detects that a certain application or a certain interface is running. The camera 120 is turned on, detects at least one face image within the camera range of the terminal 110, for example, the camera 120 captures an image within the camera range thereof, the terminal 110 recognizes the at least one face image in the image, and compares each face image in the at least one face image with a face image of each authorized user. The camera shooting range can be understood as the maximum range that the camera 120 in the terminal 110 can capture, and the range can be understood as the angle range that the terminal 110 can shoot, and is generally 60 degrees to 80 degrees. It should be noted that, when the terminal 110 includes a plurality of cameras, a union of maximum acquisition ranges of the plurality of cameras is regarded as an acquisition range of the terminal 110, or a union of maximum acquisition ranges of the cameras to which the data processing method in the embodiment of the present application has authority to access is regarded as an acquisition range of the terminal 110. Referring to fig. 3, an exemplary diagram of a shooting range provided in the embodiment of the present application is shown, where an included angle range between two straight lines is a shooting range of the camera 120.
If each detected face image in the at least one face image can determine a matched face image in the pre-stored face images of the authorized users, the terminal 110 determines that no unauthorized user exists in the camera shooting range of the terminal. If one face image exists in at least one detected face image and a matched face image cannot be determined in the pre-stored face images of the authorized users, the terminal 110 determines that an unauthorized user exists in the camera shooting range of the terminal.
The following describes an example of a manner of matching face images, taking matching one of at least one detected face image as an example:
the terminal 110 extracts the face image and the face features of the face image of each authorized user, and calculates the similarity between the face features of the face image and the face features of the face image of each authorized user, for example, calculates the euclidean distance or the cosine similarity. If the similarity between the facial features of the facial image and the facial features of the facial image of an authorized user is greater than a preset threshold value, the facial image is matched with the facial image of the authorized user, otherwise, the facial image is not matched with the facial image of the authorized user.
After the detected face images are matched, if it is determined that an unauthorized user does not exist in the image pickup range of the terminal, which indicates that the data is not at risk of being peeped, the terminal 110 does not perform any operation, so that the user normally views the target data. If the terminal 110 determines that there is an unauthorized user in its imaging range, which indicates that there is a risk of data being peeped, step S220 is performed hereinafter.
And S220, if an unauthorized user exists in the camera shooting range of the terminal, determining the distance between the terminal and the unauthorized user.
If it is determined that an unauthorized user exists in the camera shooting range of the terminal 110, the unauthorized user may not be able to clearly see the content displayed on the display screen 130 due to the influence of the distance, so that in the embodiment of the present application, the distance between the terminal 110 and the unauthorized user needs to be determined, so as to prevent the terminal 110 from starting the data protection mode and influencing the normal use of the user under the condition that the unauthorized user cannot clearly see the content displayed on the display screen 130. The distance between the terminal 110 and the unauthorized user may be a straight line distance between a projected point of the terminal 110 on the ground and a projected point of the unauthorized user on the ground, or a vertical distance between a horizontal line where the terminal 110 is located and a horizontal line where the unauthorized user is located.
Specifically, the terminal 110 has a distance sensor therein, and the distance between the terminal 110 and an unauthorized user is detected by the distance sensor. The distance sensor obtains the distance between the terminal 110 and the unauthorized user by calculating the time from when the energy beam is transmitted to when the energy beam is reflected back by the unauthorized user. Energy beams such as electromagnetic waves, ultrasonic waves, acoustic waves, infrared light, and the like.
Alternatively, the terminal 110 determines the distance of the terminal 110 from the unauthorized user in accordance with the size ratio of the detected face image. For example, if the area ratio of the rectangular frame where the detected face image is located to the whole image is 1:10, the distance between the terminal 110 and the unauthorized user is 10 meters; if the area ratio of the rectangular frame in which the detected face image is located to the entire image is 3:10, the distance between the terminal 110 and the unauthorized user is 3 meters.
After determining the distance between the terminal 110 and the unauthorized user, the terminal 110 compares the distance with a preset threshold to determine whether the unauthorized user can see the contents displayed on the display 130. The preset threshold is set by the user through a plurality of trials, and may be, for example, the maximum distance that the user can see the content displayed on the display 130 from various angles. For the unauthorized users corresponding to different angles, the corresponding preset thresholds may be different or the same, for example, the maximum distances at which the users see the content displayed on the display screen 130 from different angles are different, the maximum distances corresponding to different angles are set as the preset thresholds corresponding to the angles, or the maximum value among the maximum distances corresponding to different angles is set as the preset threshold corresponding to each angle.
If the distance between the terminal 110 and the unauthorized user is greater than a preset threshold. In this case, although there is an unauthorized user in the image capturing range of the terminal 110, the distance between the unauthorized user and the terminal 110 is too far to see the content displayed on the display 130, which means that there is no risk of peeping the target data, and the terminal 110 does not perform any operation, so that the user can view the target data normally. If the distance between the terminal 110 and the unauthorized user is less than the preset threshold. In this case, an unauthorized user is present in the imaging range of the terminal 110, and the unauthorized user can see the content displayed on the display 130, indicating that the target data is at risk of being peeped, and execute step S230 below.
It should be noted that there may be one or more unauthorized users, and when there are a plurality of unauthorized users, the terminal 110 may detect the distance to each unauthorized user separately. As long as there is an unauthorized user whose distance from the terminal is smaller than the corresponding preset threshold, it is determined that the distance between the terminal 110 and the unauthorized user is smaller than the preset threshold.
And S230, if the distance is determined to be smaller than the preset threshold value, adjusting the color parameter of the display screen of the terminal so as to enable the display screen to enter a data protection mode.
If it is determined that an unauthorized user exists in the camera shooting range of the terminal 110 and the distance between the terminal 110 and the unauthorized user is smaller than a preset threshold, the color parameter of the display screen 130 of the terminal 110 is adjusted so that the display screen 130 enters a data protection mode. When the display screen 130 is in the data protection mode, an unauthorized user cannot view the content displayed on the display screen 130 from any angle, so that data is prevented from being peeped.
In a possible embodiment, before the display screen 130 enters the data protection mode, in order to improve user experience, the terminal 110 may perform a reminding operation, so as to avoid that the display screen 130 enters the data protection mode without the user's knowledge, which affects the user's use. Wherein the reminding operation comprises one or more of the following steps:
1. and displaying the first prompt message.
To enter the data protection mode as soon as possible, a first type of prompt is used to prompt the user that the display screen 130 is about to enter the data protection mode. The content of the first type of prompt message is, for example, "find the data is at risk of being peeped, and enter the data protection mode after 3 seconds". After the first prompt message is displayed, the display 130 will automatically enter the data protection mode after 3 seconds.
2. And displaying the second prompt message.
Since the user may newly recognize the authorized person but has not been stored in the terminal 110, in order to avoid frequently entering the data protection mode and affecting the normal use of the user, the second prompting message is used to prompt the user whether to select to enter the data protection mode. The content of the second type of prompt message is, for example, "find the data is at risk of being peeped, confirm to enter the data protection mode? ".
After the display 130 displays the second prompt message, when the terminal 110 confirms the confirmation operation performed by the user for the second prompt message, the display 130 is switched to the data protection mode. When the terminal 110 confirms the unconfirmed operation of the user with respect to the second prompt information, the display screen 130 does not enter the data protection mode, and displays the previously displayed content, which is the content displayed by the display screen 130 before the second prompt information pops up. For example, when the user views the target photo, the display screen 130 pops up the second prompt information, and in response to the user performing an unconfirming operation on the second prompt information, the display screen 130 displays the target photo that the user previously viewed.
In order to avoid an unauthorized user viewing the target data using the terminal 110, the terminal 110 determines whether the user currently using the terminal 110 is an authorized user before confirming the confirmation or non-confirmation operation of the user for the second prompt information. If the user currently using the terminal 110 is determined to be an authorized user, the terminal 110 responds to the user to confirm or not confirm the second prompt message.
Further, after the preset time is exceeded, the terminal 110 does not detect any operation of the user, and automatically switches the display screen 130 to the data protection mode. For example, the preset time is 10 seconds, and within 10 seconds, after the terminal 110 confirms the confirmation operation of the user for the prompt information, the display screen 130 is switched to the data protection mode. Or the user does not perform any operation within 10 seconds, and after 10 seconds, the terminal 110 automatically switches the display screen 130 to the data protection mode.
Referring to fig. 4A, an example of an interface for displaying first prompt information provided in the present application is shown, where only the prompt information exists in the interface, and no other keys exist, and the display screen 130 is automatically switched to the data protection mode. Referring to fig. 4B, there are schematic diagrams of an interface for displaying second prompt information according to an embodiment of the present application, where the interface includes a prompt information "confirm" button 401 and a "cancel" button 402. When the user clicks the "confirm" button 401, the user performs a confirmation operation on the second prompt information, and the user selects to enter the data protection mode; when the user clicks the "cancel" button 402, this corresponds to an unconfirming operation performed by the user for the second prompt information, and represents that the user selects not to enter the data protection mode.
3. The display 130 is controlled to blink at a certain frequency, for example, the terminal 110 controls the display 130 to blink once per second for 3 seconds.
4. Vibration is performed, for example, the terminal 110 is continuously vibrated for 3 seconds.
5. The flash is controlled to flash at a certain frequency, for example, the flash of the camera 120 controlled by the terminal 110 flashes once per second for 3 seconds.
6. Issuing an alert tone, e.g. the player of the terminal 110 issues an alert tone: "find the data is peeped at risk, enter data protection mode after 3 seconds".
Further, the terminal 110 may perform one or more alerting operations or may not perform the alerting operation in response to a user's setting operation for the data protection mode. For example, the user opens a specific application in the terminal 110, sets whether to perform a reminder operation in the specific application, or sets to perform one or more reminder operations.
The terminal 110 adjusts the color parameters of the display 130 to cause the display 130 to enter a data protection mode. The color parameter may be a color, such as black, white, etc. The color parameter may be transparency, which refers to the transmittance of light through the color-changing film layer 150, such as 100%, 0%, etc., wherein 100% transparency is a fully transparent mode and 0% transparency is an opaque mode.
The target color parameters for controlling the display 130 may be fixed or dynamically determined, as exemplified below:
first, the target color parameters are dynamically determined.
The terminal 110 prestores a corresponding relationship between the illumination parameter of the ambient light and the color parameter of the display screen 130, and the target color parameter of the display screen 130 is dynamically determined according to the illumination parameter of the current ambient light and the corresponding relationship. The lighting parameter may be a color, such as white, yellow, etc. The illumination parameter may be illumination intensity, which is used to indicate the intensity of illumination, such as 100000 lux for summer sunlight and 10000 lux for cloudy outdoor sunlight.
If the target color parameters of the display screen 130 are different, the illumination parameters of the ambient light to be obtained are different, and specific examples are described as follows:
(1) when the terminal 110 needs to adjust the color of the display screen 130 to achieve the purpose of data protection, the terminal 110 may collect the illumination parameter of the ambient light as the color, and determine the target color parameter of the display screen 130 according to the color and the corresponding relationship.
For example, the corresponding relationship is: the color of the ambient light is yellow and the color parameter of the display screen 130 is yellow.
(2) When the terminal 110 needs to adjust the transparency of the display screen 130 to achieve the purpose of data protection, the terminal 110 may collect the illumination parameter of the ambient light as the illumination intensity, and determine the target color parameter of the display screen 130 according to the illumination intensity and the corresponding relationship.
For example, the corresponding relationship is: the illumination intensity of the ambient light is 10000 lux, and the color parameter of the display screen 130 is transparency 50%; the illumination intensity of the ambient light is 100 lux, and the color parameter of the display screen 130 is transparency 20%.
(3) When the terminal 110 needs to adjust the color and the transparency of the display screen 130 to achieve the purpose of data protection, the terminal 110 may collect the illumination parameters of the ambient light as the color and the illumination intensity, and determine the target color parameter of the display screen 130 according to the color, the illumination intensity, and the corresponding relationship.
For example, the corresponding relationship is: the color of the ambient light is yellow, the illumination intensity is 10000 lux, and the target color parameter of the display screen 130 is yellow and the transparency is 20%.
Second, the target color parameters are fixed.
The target color parameters for the display screen 130 to enter the data protection mode are fixed regardless of the color and illumination intensity of the ambient light. For example, the target color parameter of the display screen 130 is black and the transparency is 0%.
After determining the target color parameters of the display screen 130, the terminal 110 may control the color-changing film layer to display the color-changing film layer according to the target color parameters. For example, if the color-changing thin film layer 150 is electrochromic glass, the terminal 110 applies an electrical signal to the color-changing thin film layer 150 to display the color-changing thin film layer 150 according to the target color parameters. Or the color-changing film layer 150 is thermochromic glass, the terminal 110 controls the temperature of the color-changing film layer 150 to display the color-changing film layer 150 according to the target color parameter. For example, the terminal 110 may control the temperature of the thermochromic glass by passing a thermistor in the thermochromic glass.
After the terminal 110 switches the display 130 to the data protection mode, the user may adjust the position or angle, continue to detect whether there is an unauthorized user within the image capture range of the terminal 110, and determine the distance between the terminal 110 and the unauthorized user to determine whether the risk of data being peeped is removed. For the way of detecting the unauthorized user and the way of determining the distance between the terminal 110 and the unauthorized user, please refer to the above discussion, which is not repeated herein.
When an unauthorized user does not exist in the camera shooting range of the terminal 110 or the distance between the terminal 110 and the unauthorized user is greater than a preset threshold value, the risk that data is peeped is eliminated, and the color parameter of the display screen 130 is adjusted, so that the display screen 130 is switched to a normal display mode. Wherein, when the display screen 130 is in the normal display mode, the user can normally view the content displayed on the display screen 130. For example, when the terminal 110 detects that the user opens the target photo, the display screen 130 enters a data protection mode, and when the risk of peeping data is removed and the display screen 130 is in a normal display mode, the display screen 130 continues to display the target photo.
Specifically, the terminal 110 may store the color parameter of the display 130 before entering the data protection mode, and adjust the color parameter of the display 130 to the color parameter before switching. Or the terminal 110 may directly adjust the color parameters of the display 130 to a fixed color and a fixed transparency. For example, in the data protection mode, the target color parameter of the display 130 is black and the transparency is 0%, and in the normal display mode, the color parameter of the display 130 is white and the transparency is 100%.
