Detailed Description
The purpose, technical solutions and advantages of the present application will become more apparent from the following detailed description of the present application with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In an embodiment, as shown in fig. 1, a terminal-based information display method is provided, and this embodiment is illustrated by applying the method to a terminal, it is to be understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and is implemented by interaction between the terminal and the server. In this embodiment, the terminal includes a shooting component disposed on a screen side of the terminal, and the method includes the following steps:
and 102, acquiring target information to be displayed.
The target information can be understood as private information which is newly received by the terminal and needs to be displayed, and the private information can be relatively private information which is not expected to be seen by other people.
Specifically, the terminal receives target information to be displayed; or, when the current condition meets the preset display condition, for example, when the current time is within the time period of displayable information, the terminal acquires the target information in the received information to be displayed.
And step 104, taking the currently displayed interface as the currently displayed interface.
Specifically, the interface currently displayed in the terminal screen is used as the current display interface.
And 106, when the current display interface is switched to the target interface, acquiring the image acquired by the shooting assembly.
The target interface is an interface capable of displaying target information, such as an information notification interface or an information display interface.
Specifically, the terminal determines whether the current display interface of the terminal is switched to a target interface from other interfaces based on an interface switching instruction generated by user triggering, an interface switching operation executed by the terminal or periodically detecting the current display interface of the terminal, and controls a shooting assembly arranged on the side of a terminal screen to collect an image of a scene in front of the terminal screen and acquire the image when detecting that the current display interface is switched to the target interface.
It should be noted that, this embodiment does not limit the installation position of the shooting component, the shooting component may be installed on the screen side of the terminal, such as the front camera of the terminal, or may be installed on a side away from the terminal screen, such as the rear camera of the terminal, only the image of the scenery located in front of the terminal screen needs to be collected, when the shooting component is the rear camera of the terminal, the camera may be a camera with an adjustable shooting direction, and thus, when the current display interface is switched to the target interface, the terminal may adjust the shooting direction of the rear camera thereof, so that the terminal can collect the image of the scenery located in front of the terminal screen.
In one embodiment, the target interface is an information notification interface; when the current display interface is switched to the target interface, acquiring the image acquired by the shooting assembly comprises the following steps: monitoring interface switching operation between display interfaces; the interface switching operation comprises the operation that the terminal is switched from one currently displayed interface to another interface to display; when the current display interface is monitored to be switched to the information notification interface, displaying an information notification bar area; when the triggering operation of a user in the information notification bar area is monitored, starting a shooting component; and acquiring an image collected by the shooting assembly.
The interface switching operation can be triggered by a user or automatically executed by the terminal when the current condition meets the switching condition of the interface. The information notification interface may be a lock screen interface or a notification bar interface. The screen locking interface is a display interface when the terminal screen is awakened but in a screen locking state, and the switching mode of the screen locking interface can be flexibly set, for example, the terminal can awaken the screen by a user in a screen extinguishing state or automatically awaken the screen by the terminal, or switch the current display interface to the screen locking interface by the user in a screen locking state or automatically lock the screen by the terminal in a screen unlocking state; the notification bar interface is a display interface of the terminal notification bar, such as a pull-down interface of the terminal, and a user can switch the display interface of the terminal to the notification bar interface in a pull-down manner, or the terminal can automatically switch to the notification bar interface when receiving new information.
Specifically, the terminal monitors the interface switching operation of switching the currently displayed interface into another interface for display; when the interface switching operation is monitored, executing the interface switching operation, and judging whether the current display interface is an information notification interface after switching; if the current display interface is the information notification interface, displaying an information notification area in the current display interface, and monitoring whether a user triggers an operation of displaying target information in the information notification bar area, such as a click operation or a sliding operation; and then, when the triggering operation of the user in the information notification bar area is monitored, starting the shooting component, controlling the shooting component to acquire the image of the scene in front of the screen side of the terminal and acquiring the image acquired by the shooting component.
It is understood that, after the information notification area is displayed, the terminal may further display a new information notification that does not relate to the information content of the target information or the content related to the information sender in the information notification area to prompt the user to receive the new information.
In another embodiment, when the target interface is the information display interface and the current display interface is switched to the target interface, acquiring the image acquired by the shooting component includes: monitoring interface switching operation between display interfaces; the interface switching operation comprises the operation that the terminal is switched from one currently displayed interface to another interface to display; when the current display interface is monitored to be switched to the information display interface, displaying an information display area; an information sender for displaying the target information in the information display area; when the triggering operation of a user in the information display area is monitored, starting a shooting assembly; and acquiring an image collected by the shooting assembly.
The information display interface is an interface used by the terminal to display the received information to be displayed (such as target information).
Specifically, the terminal monitors the interface switching operation of switching the currently displayed interface into another interface for display; when the interface switching operation is monitored, executing the interface switching operation, and judging whether the current display interface is an information display interface after switching; if the current display interface is the information display interface, displaying an information display area in the current display interface, displaying the sending of the target information in the information display area, and monitoring whether a user triggers the operation of displaying the target information in the information display area, such as clicking operation or sliding operation; and then, when the triggering operation of the user in the information display area is monitored, starting the shooting assembly, controlling the shooting assembly to acquire the image of the scene in front of the screen side of the terminal and acquiring the image acquired by the shooting assembly.
And 108, carrying out face area identification on the image to obtain a corresponding face image.
The face region can be understood as a region corresponding to an image of a human face in an image acquired by the shooting component. The face image can be an image of a face which can be recognized by the terminal in the acquired image; moreover, when people around the terminal are far away from the terminal, the content of the target information displayed on the terminal target interface cannot be clearly seen, so the face image can also be an image of a face which can be recognized by the terminal in the acquired image and has a distance from the terminal smaller than a preset distance threshold. The face image can be a complete or incomplete face image; the preset distance threshold may be determined according to the font size of the target information when displayed in the target interface, for example, when the display font size of the target information is small (e.g., size six), the preset distance threshold may be set to a small value (e.g., 1 m); when the display font size of the target information is large (e.g., four), the preset distance threshold may be set to a large value (e.g., 3 m).
Taking the face image as an image of a face which can be recognized by the terminal and has a distance from the terminal smaller than a preset distance threshold as an example, the step may specifically be: the terminal adopts a face recognition technology to recognize a face area of an image, in which a face is displayed, in the image collected by the shooting component, determines the distance between the corresponding face and the terminal according to depth information of pixels corresponding to the image of the face in the face area, and acquires a face image formed by the face, in which the distance between the face and the terminal displayed in the face area is smaller than a preset distance threshold value.
It should be noted that the number of times of face region recognition performed by the terminal may be flexibly set, for example, after the current display interface is switched to the target interface, the terminal may periodically acquire an image acquired by the shooting component and perform face region recognition on the acquired image until the display interface of the terminal is switched to a non-target interface or only one face exists within the shooting range of the camera and the face is the face of the terminal owner; the operation of acquiring the image acquired by the photographing component and performing face region recognition thereon may be performed only once.
And step 110, when a plurality of faces exist in the face image, encrypting the target information to obtain encrypted information.
Specifically, when a plurality of human faces exist in the face image, a preset encryption mode is adopted to encrypt an encryption object set in the target information, so as to obtain encrypted information.
The encryption object and the encryption mode of the target information can be set according to requirements. For example, the sender of the target information and the information content may be encrypted at the same time; only the information content of the target information or only part of private characters in the information content of the target information may be encrypted. For another example, when encrypting the encrypted object, a preset encryption algorithm may be used to encrypt the encrypted object into a statement that does not have an actual meaning; each character in the encrypted object can be replaced by a preset character (such as the character "X"), or the whole encrypted object can be replaced by a set word (such as the word "private short message" or "private information").
In a preferred embodiment, when the target interface is an information notification interface, encrypting the target information to obtain encrypted information includes: and respectively encrypting the information sender and the information content of the target information to obtain sender encryption information and content encryption information. When the target interface is an information display interface, encrypting the target information to obtain encrypted information comprises: and encrypting the information content of the target information to obtain corresponding content encryption information.
In the above embodiment, as shown in fig. 2 to 4, when the terminal displays the information notification interface, the terminal screen may not be in an unlocked state, that is, the terminal may not have authenticated the user currently using the terminal, and when the information display interface is displayed, the terminal screen is necessarily in an unlocked state, and before that, the terminal has authenticated the user currently using the terminal once when unlocking the screen, so that when the current display interface is the information notification interface, both the information sender and the information content of the target information may be encrypted, so as to further improve the security of the target information; when the current display interface is the information display interface, only the information content of the target information can be encrypted, so that the user can check the information sender of the target information, and the user can conveniently determine whether to find an unmanned position to check the information content of the target information.
And step 112, displaying the encrypted information on the target interface.
The display position of the encrypted information on the target interface can be flexibly set, such as the target information can be displayed at the upper part, the lower part or the middle part of the target interface, and the like. In view of convenience of the user in viewing the encrypted information, it may be preferable to display the target information in an information notification bar area of the information notification interface or display the target information in an information display area of the information display interface, such as when the target interface is the information notification interface, sender encrypted information and content encrypted information of the target information in the information notification bar area; and when the target interface is an information display interface, displaying an information sender and content encryption information of the target information in the information display area.
Specifically, when a plurality of faces exist in the face image, it means that the content displayed in the target interface has a risk of being seen by other people except the terminal owner, and therefore, when a plurality of faces to be recognized exist in the shooting range of the camera, the encrypted information of the target information can be displayed on the target display interface, so that on the premise of informing the user terminal of receiving new information, the target information received by the terminal is prevented from being seen by other people, and the target information is prevented from being leaked.
For example, in an application scenario, a certain user and a friend are watching a video through a mobile phone of the user, at this time, new private information received by the user is automatically popped up on the notification bar interface, if a conventional information display method is adopted, the terminal will normally display part or all of the content of the received private information in the notification bar interface, and the displayed information content will be seen by the friend watching the video together with the user besides being seen by the user, so that embarrassment may be brought to the user, and even an immeasurable loss may be brought to the user due to leakage of the information content of the private information (for example, when the information content includes a business secret). After the terminal-based information display method provided by this embodiment is adopted, the private information received by the terminal is displayed in an encrypted manner, that is, the encrypted private information (such as sender encrypted information and content encrypted information) is displayed in the notification bar interface, at this time, even if the notification bar interface is seen by a friend, the sender and the information content of the private information cannot be known, so that the situation that the private information is leaked is avoided, and the information security of the private information is ensured.
It can be understood that, after the terminal encrypts the target information in the display terminal in the target interface, if the operation of displaying the original content of the target information before encryption in the target interface is detected, if the user is detected to trigger the click or sliding operation of viewing the information content of the target information, the user can be reminded that the risk of information leakage exists when viewing the target information at the moment, and after the user clicks the confirmation viewing control, whether the faces of the terminal owner exist in the faces is further identified, that is, whether the preset faces exist in the faces is identified, if so, the information sender and the information content of the target information are displayed in the target interface, so that the terminal owner can view the target information in an emergency; if not, continuing to display the encrypted information of the target information in the target interface.
According to the terminal-based information display method, target information to be displayed is obtained, when a currently displayed interface is switched to be the target interface, an image collected by a shooting assembly arranged on the screen side of the terminal is obtained, and a human face in the image is recognized. When the image is identified to contain a plurality of faces, target information to be displayed is encrypted and displayed on a target interface, so that the encrypted display of the target information of a plurality of faces in front of a terminal screen is realized. Therefore, the private information is prevented from being seen by other people except the terminal owner, information leakage of the target information is avoided, and the safety of the target information is improved.
In another embodiment, as shown in FIG. 5, a method of displaying information is provided. The present embodiment is optimized based on the above embodiments. In this embodiment, the method includes the steps of:
The information type of the information to be displayed can be short message, multimedia message, WeChat information, QQ information or other types of chat information and the like.
And 204, analyzing the information to be displayed to obtain an information sender and information content of the information to be displayed.
In step 206, if the sender is a set private sender and the content of the message includes a preset keyword, the message to be displayed is determined as the target message to be displayed.
The private sender and the preset keywords may be set by the terminal owner and/or the terminal developer in advance according to needs, for example, the private sender may be a bank, an insurance company and/or each software developer, and the preset keywords may include, but are not limited to, payroll, income, balance, a verification code, and the like, so as to ensure financial privacy and security of the user.
Specifically, a terminal receives information to be displayed sent by a base station or other equipment; analyzing the information to be displayed to obtain an information sender and information content of the information to be displayed, judging whether the information sender of the information to be displayed is a private sender and whether the information content of the information to be displayed contains preset keywords or not aiming at each information to be displayed, and determining the information to be displayed as target information to be displayed when the information sender is judged to be the private sender and the information content contains the preset keywords.
Correspondingly, if the information sender of the information to be displayed is not a set private sender and/or the information content of the information to be displayed does not contain preset keywords, it can be determined that the information to be displayed is not the target information. Therefore, when monitoring that the current display interface is switched to the target interface, the terminal displays the information to be displayed and the content to be displayed corresponding to the target interface in the target interface, for example, when the target interface is an information notification interface, a sender and an information abstract (such as partial or all information content) of the information to be displayed are displayed in the target interface; and when the target interface is an information display interface, displaying a sender of the information to be displayed and complete information content in the target interface.
In an embodiment, taking the terminal as a mobile phone and taking the information to be displayed as a short message as an example, the mobile phone may receive and analyze a short message sent by the base station and then display the analyzed short message, specifically as shown in fig. 6, the mobile phone may receive a short message in a digital signal form sent by the base station through a Modem (Modem) and convert the short message into a short message in an analog signal form, analyze the converted short message through a telephone communication program (Telephony) in the mobile phone, display a short message Notification through a Notification program (Notification) in the mobile phone and read the information through a short message application program (APP) in the terminal, so that the mobile phone may determine a sender and information content of the short message in a process of analyzing the short message, and further determine whether the short message is a private short message, that is, i.e., determine whether the short message is a target message.
It can be understood that the terminal may also determine whether the information to be displayed is the target information according to at least one of the receiving time of the information to be displayed, the sender, the information content, and the information type, for example, determine whether the receiving time of the information to be displayed is within a preset time period, whether the sender is a private sender, whether the information content includes a preset keyword and/or whether the information type is a preset information type, and the like, so as to determine whether the information to be displayed is the target information.
And step 208, taking the currently displayed interface as the currently displayed interface.
And step 210, when the current display interface is switched to the target interface, acquiring an image acquired by the shooting assembly.
And step 212, carrying out face region identification on the image to obtain a corresponding face image.
Exemplarily, as shown in fig. 7 (the dots in the figure are feature points in a face image, and the white font is feature information at the feature points of the face), the terminal uses a shooting component on the terminal screen side in advance to record face feature information of a terminal owner, such as feature information of a nose, eyes, a mouth corner and other parts of the terminal owner, and stores the face feature information in a set storage location or writes in a system file; when the face image is determined to contain only one face, the terminal acquires face feature information of the face, compares the face feature information with face feature information of a terminal owner stored in the terminal, calculates similarity of the face feature information and the face feature information, and determines that a current user corresponding to the face image in front of a terminal screen at the moment is the terminal owner and the face identification is passed if the similarity is greater than or equal to a preset similarity threshold (such as 95%); otherwise, determining that the current user is not the terminal owner and the face recognition is not passed.
At step 218, the target information is displayed on the target interface.
Specifically, when the face recognition is passed, it is determined that the current user is the terminal owner, and the content to be displayed corresponding to the target display interface in the target information is displayed in the target interface, for example, when the target interface is a screen locking interface or a notification bar interface, an information sender and an information abstract of the target information are displayed in the target interface, as shown in fig. 8 and 9; when the target interface is an information display interface, an information sender and information content of the target information are displayed in the target interface, as shown in fig. 10.
Specifically, when only one face exists in the face image and the face recognition is not passed, or when the face does not exist in the face image or a plurality of faces exist in the face image, the target information in the display terminal is encrypted in the target interface, for example, an information summary (for a case that the target interface is a lock screen interface or a notification bar interface) or information content (for a case that the target interface is an information display interface) of the target information is encrypted into a preset word, and the preset word is displayed in the target interface, as shown in fig. 2 to 4.
In one embodiment, the terminal may determine whether the terminal is in a screen locking state when the information notification interface detects an operation instruction to enter the information display interface, perform authentication on a current user of the terminal when the terminal is in the screen locking state, switch the current display interface of the terminal to the information display interface when the authentication passes, and continue to display the current information notification interface without performing an operation of switching the display interface of the terminal to the information display interface when the authentication fails; and when the terminal is not in the screen locking state, switching the current display interface of the terminal into an information display interface.
