In other embodiments of the present application, the handset 100 may include more or fewer components than shown, or certain components may be combined, or certain components may be split, or different arrangements of components may be provided. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

It should be noted that, in the prior art, the mobile phone 100 may store an image and a video, and attribute information corresponding to the image and the video, where the attribute information is, for example, information included in an exchangeable image file format (exchangeable image file format, exif), and the attribute information includes privacy information and non-privacy information corresponding to the image and the video, when the mobile phone 100 receives request information for requesting to acquire the image by an application (or detects an input operation, such as an operation for publishing the image or an operation for sending the image to other contacts), after the image is selected by the user, if privacy protection is selected by the user at the same time, the privacy information needs to be erased, and the image sharing efficiency is low. And if abnormal conditions such as network faults occur, the privacy information may not be successfully wiped out, and the probability of privacy disclosure exists.

In the embodiment of the present application, after capturing an image, the mobile phone 100 may store media data of the image and non-private information (attribute information other than the private information) in the first storage area and private information in the second storage area. When the mobile phone 100 detects the request information for the first application to request to acquire an image, the media data and the non-private information of the image can be acquired and transmitted from the first storage area, without acquiring the private information from the second storage area, reducing the probability of privacy disclosure.

In some embodiments, the software system of the handset 100 may employ a layered architecture, an event driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The following embodiments exemplify a layered android (android) system, and exemplify the software structure of the mobile phone 100.

Fig. 1B is a block diagram of a software architecture of a mobile phone 100 according to an embodiment of the present application. The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. In some embodiments, an android system may be divided into four layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun row (android run) and system libraries, and a kernel layer, respectively. The application layer may include a series of application packages. As shown in fig. 1B, the application package may include applications for cameras, gallery, calendar, phone calls, maps, navigation, WLAN, bluetooth, music, video, short messages, etc. The application framework layer provides an application programming interface (application programming interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 1B, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like. The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like. The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc. The view system includes visual controls, such as controls to display text, controls to display images, and the like. The view system may be used to build applications. The display interface may be composed of one or more views.

For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

an android run includes a core library and virtual machines. android run is responsible for scheduling and management of android systems. The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android. The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application program layer and the application program framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), etc.

The surface manager is used for managing the display subsystem and providing fusion of 2D and 3D layers for a plurality of application programs.

Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio video encoding formats, such as: MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc.

It should be noted that, in the embodiment of the present application, the media library is further configured to obtain media data and attribute information of a media file, where the attribute information includes one or more of the following: media type (image or video), theme (title), resolution, photographing time, lens parameters (focal length, exposure time, aperture value, etc.), position information (geographical position information, such as latitude and longitude information), device model, etc. In the embodiment of the application, the electronic device stores media data and non-private information (such as one or more of media type, title, resolution, etc.) of the media file in a first storage area (for example, a non-private database described below), and stores private information (such as shooting time, lens parameters, location information, device model, etc.) in a second storage area (for example, a private database described below). When sharing the media file, the electronic device can acquire the media data and the non-private information from the first storage area and acquire the private information from the second storage area through the media library. As an example, the media library described in the embodiments of the present application provides two interfaces, a first interface (e.g., a first interface described below) for acquiring media data and non-private information from a first storage area, and a second interface (e.g., a second interface described below) for acquiring media data and non-private information from a first storage area, and private information from a second storage area. Optionally, the media library may also perform a rights check on the application requesting the acquisition of the media file.

The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

For easy understanding, the following embodiments of the present application will take a mobile phone having a structure shown in fig. 1A and fig. 1B as an example, and the media file storage and sharing method provided in the embodiments of the present application will be described with reference to the accompanying drawings. The implementation process of the technical scheme of the application is described below in different application scenes. In the following description, the media file is taken as an example of an image.

Scene 1-camera applications

Referring to fig. 2 (a), the mobile phone 100 displays a main interface 201, and the main interface 201 includes application icons of a plurality of applications (camera application, gallery application, calendar application, etc.). For example, when the mobile phone 100 detects an operation of the icon 202 triggering the camera application by the user, the mobile phone 100 may display the photographing interface 203 of the camera application, as shown in (b) of fig. 2.

In one embodiment, referring to (b) of fig. 2, the image displayed by the photographing interface 203 of the camera application is a preview image, which is an image captured by the mobile phone 100 based on preset photographing parameters of the camera.

In one embodiment, referring to fig. 2 (b), the capture interface 203 of the camera application also displays options for selecting media types, such as a "capture" corresponding option 204, a "video" corresponding option 205, and a control 206, and when the control 206 is triggered, an image or video may be captured and the captured image or video data stored in a designated location.

As an example, assuming that the user currently selects the option 204 corresponding to "photograph", when the mobile phone 100 detects that the user triggers the control 206, the camera applies to photograph an image, and stores the data of the photographed image to a designated location (e.g., stores the media data and non-privacy information of the photographed image to a first storage area, and stores the privacy information of the image to a second storage area), so that when the mobile phone 100 performs image sharing, the mobile phone 100 can acquire and send the data of the image from the designated location, so as to realize the sharing of the image.

In the scene 2, the camera application, after capturing an image, reduces the probability of privacy disclosure by storing media data and non-private information of the captured image in the first storage area and storing the private information of the image in the second storage area, so that when detecting an operation of sharing the image by the user, the mobile phone 100 can acquire and transmit the media data and the non-private information of the image from the first storage area without acquiring the private information of the image from the second storage area.

Scene 2-social application

See (a) in fig. 3A. The handset 100 displays an interface 301 of the social application, including a control 302 in the interface 301. When the control 302 is triggered, the handset 100 displays a capture option 303 and an option 304 for selecting an image from the gallery, see (b) in fig. 3A.

When the mobile phone 100 detects that the image option 304 is selected from the gallery, the mobile phone 100 displays an image candidate interface 305, as shown in (c) of fig. 3A.

As an example, see (c) in fig. 3A. The image candidate interface 305 includes thumbnail images of a plurality of images in a gallery in the mobile phone 100, and when the mobile phone 100 detects that the image 306 is selected, the mobile phone 100 displays an option 309 corresponding to "send privacy information" and an option 310 corresponding to "do not send privacy information", as shown in (a) in fig. 3B. Alternatively, when the mobile phone 100 detects that the image 306 is selected, the mobile phone 100 displays options for parameters of the privacy information, including one or more of: an option 311 corresponding to "none", an option 312 corresponding to "shooting time", an option 313 corresponding to "lens parameter", an option 314 corresponding to "shooting position information", an option 315 corresponding to "device model", and an option 316 corresponding to "finish", see (B) in fig. 3B. Wherein, when the user does not need to acquire the private information, the option 311 corresponding to "none" may be selected, and when the user does not need to continue to select the parameter of the private information, the option 316 corresponding to "complete" may be selected. Note that, the content displayed by the mobile phone 100 is not limited to the above text content, and the user may be directly prompted to: the data related to the privacy information such as the shooting time and the shooting position information is not transmitted, wherein the prompt can be a text prompt or a voice prompt.

For example, when the mobile phone 100 detects that the image 306 is selected, the mobile phone 100 sends first request information for acquiring the image 306 to the media library through the social application, and displays an interface as shown in (a) in fig. 3B to ask the user if the user needs to send the privacy information, and if the user selects the option 310 corresponding to "do not send the privacy information", the mobile phone 100 sends first indication information for indicating that the privacy information is not sent to the media library through the social application, and the media library acquires and sends the media data and the non-privacy information of the image 306 from the first storage area when receiving the first request information and the first indication information.

For another example, when the mobile phone 100 detects that the image 306 is selected, the mobile phone 100 displays an interface as shown in (B) in fig. 3B to inquire about parameters of privacy information that the user needs to send, and if the user selects the option 311 corresponding to "none", the mobile phone 100 sends first request information for acquiring the image 306 to the media library through the social application, where the first request information does not include parameters of privacy information, and when the media library receives the first request information, the media library acquires and sends media data and non-privacy information of the image 306 from the first storage area. If the user selects the option 313 corresponding to the "lens parameter", the mobile phone 100 sends the first request information to the media library through the social application, where the first request information includes the lens parameter, and when the media library receives the first request information, the media library obtains the media data and the non-privacy information of the image 306 from the first storage area, and obtains the lens parameter information of the image 306 from the second storage area.

Alternatively, when the mobile phone 100 displays the interface shown in (B) in fig. 3B, if the mobile phone 100 detects that the user selects the option 311 corresponding to "none", the mobile phone 100 displays the option corresponding to the parameter of the privacy information (i.e. the option 312 corresponding to "photographing time", the option 313 corresponding to "lens parameter", the option 314 corresponding to "photographing position information" and the option 315 corresponding to "device model") as gray, at this time, the user cannot continue to select other options, and the user can click the option 316 corresponding to "complete" to end the selection of the parameter of the privacy information, and accordingly, when the mobile phone 100 detects that the user clicks the option 316 corresponding to "complete", the mobile phone 100 sends the first request information to the media library through the social application and exits the interface for selecting the parameter of the privacy information. Alternatively, if the mobile phone 100 detects that the user selects the option 311 corresponding to "none", the mobile phone 100 may send the first request information to the media library directly through the social application, and exit the interface for selecting the parameters of the privacy information.

Alternatively, when the user selects the parameters of the private information, one or more parameters may be selected at the same time, where if the number of parameters of the private information selected by the user is greater than or equal to 1 and less than the total number of parameters of the private information (taking (a) in fig. 3B as an example, the total number of parameters of the private information is 4), the user may click on the "complete" corresponding option 316 to end the selection of the parameters of the private information, and accordingly, when the user clicks on the "complete" corresponding option 316 is detected, the mobile phone 100 sends the first request information to the media library through the social application, and exits the interface for selecting the parameters of the private information. Or, the mobile phone 100 does not detect the parameter of selecting the privacy information by the user within the preset duration, sends the first request information to the media library through the social application, and exits the interface for selecting the parameter of the privacy information. If the number of parameters for which the user selects the private information is equal to 4, the mobile phone 100 may directly send the first request information to the media library through the social application and exit the interface for selecting the parameters for the private information.

In scenario 2, when the mobile phone 100 detects an operation for publishing an image on a social platform, an interface as shown in (a) in fig. 3B or (B) in fig. 3B may be displayed, so that a user may determine whether to share private information, or may determine parameters of the private information to be shared, so that accidental disclosure of the private information under the condition that the user is unaware is avoided, and user experience is improved.

Scenario 3-instant messaging application.

See (a) in fig. 4. The mobile phone 100 displays an interface 401 of a short message application, and the interface 401 is a communication interface between the user and other contacts. The interface 401 includes a control 402, and when the mobile phone 100 detects that the control 402 is triggered, a gallery control 403 and a shooting control 404 are displayed.

As an example, when the handset detects that the user triggers gallery control 403, an interface 405 as shown in fig. 4 (b) is displayed, with thumbnails of multiple images included in interface 405, such as image 406, image 407, and image 408 included in interface 405. Assuming that the mobile phone 100 detects that the image 406 is selected, the mobile phone 100 displays an option 409 to transmit privacy information and an option 410 to not transmit privacy information, as shown in (c) of fig. 4. Alternatively, when the mobile phone 100 detects that the image 406 is selected, the mobile phone 100 displays options of parameters of the privacy information, including: an option 411 corresponding to "none", an option 412 corresponding to "shooting time", an option 413 corresponding to "lens parameter", an option 414 corresponding to "shooting position information", and an option 415 corresponding to "device model", see (d) in fig. 4.

In the scenario 3, after the user selects based on the interface shown in fig. 4 (c) or fig. 4 (d), the interaction process of applying the short message to the media library is the same as the interaction process of applying the social contact in the scenario 2 to the media library, which is not described herein.

It should be understood that, in fig. 4, a short message application is taken as an example, and for other instant messaging applications, a similar manner may be adopted, which is not repeated.

In scenario 3, when the mobile phone 100 detects an operation for sending an image to other contacts, an interface as shown in (c) in fig. 4 or (d) in fig. 4 may be displayed, so that a user can conveniently determine whether to send private information to other contacts, or a user can conveniently determine parameters of the private information to be sent to other contacts, avoiding disclosure of the private information without the user's knowledge, and thus, improving user experience.

In the foregoing, the embodiment of the present application may store the private information and the non-private information of the media file, and referring to fig. 5, the method for storing the media file provided in the embodiment of the present application is described, where the method may be implemented by the mobile phone 100 shown in fig. 1A or other electronic devices. The media file may be an image or video, and in the following description, the media file is an image as an example.

S501: the electronic device obtains media data and attribute information of the first image.

The electronic device may acquire the media data, the private information, and the non-private information, respectively.

Optionally, the attribute information of the first image includes, for example, one or more of the following parameters: the method includes the steps of media type of a first media file, theme of the first media file, resolution of a device used for shooting the first media file, position information of the first media file, model information of the device used for shooting the first media file, shooting time of the first media file, or lens parameters of the first media file. The privacy information of the first image comprises, for example, one or more of the following parameters: location information of the first image, a model of a device (e.g., a cell phone model) for capturing the first image, a capturing time of the first image, or a lens parameter of the first image. The position information of the first image includes, for example, latitude and longitude information of a photographing device that photographs the first image when the first image is photographed. The lens parameters for capturing the first image include, for example, one or more of a focal length, an exposure time, and an aperture value of a lens for capturing the first image, and the names of the parameters included in the privacy information may be other names in practical applications.

In some embodiments, the first image may be captured by the electronic device through a camera application or other application that may capture images, or the first image may be received by the electronic device from other electronic devices through a social platform or instant messaging application, or the like.

In the process of shooting images by the camera application, the electronic equipment realizes the shooting function of the images by the camera drive and provides services to the outside by the camera service (namely a corresponding driving frame service layer of the camera drive). Thus, if the first image is captured by the electronic device through the camera application or another application that can capture an image (taking the example that the first image is captured by the electronic device through the camera application), the camera application may send a capture request to the camera service to request the camera service to report media data and attribute information of the first image during the process of capturing the first image, and the camera service may report the media data and attribute information of the first image based on the capture request after the camera is driven to capture the first image.

Optionally, the shooting request may include indication information, which indicates that the camera service separately reports the private information and the non-private information in the attribute information through different information, for example, indicates that the camera service does not write the private information into the Exif of the first image, and separately reports the private information, so that the camera service may send the private information and the Exif that does not include the private information through different information respectively. For example, the camera service may transmit Exif, which does not contain privacy information, to the camera application through the first information, and transmit privacy information to the camera application through the second information. The first information and the second information may be transmitted simultaneously or may not be transmitted simultaneously, and the transmission order is not limited. In addition, the camera service may transmit media data of the first image in addition to private information and non-private information. For example, the camera service may transmit the media data through the third information, or the camera service may include the media data in the first information. Accordingly, the camera application may acquire the private information, the non-private information, and the media data through different information, for example, the camera application may acquire the non-private information through the first information, the private information through the second information, and the media data through the third information or the first information.

Alternatively, the instruction information may not be included in the photographing request, and after the camera driver photographs the first image, the camera service may transmit media data of the first image and Exif including private information and non-private information to the camera application through the same piece of information. Alternatively, the camera service may also transmit media data of the first image and Exif including private information and non-private information to the camera application through different information, respectively. Accordingly, the camera application can acquire media data and Exif including private information and non-private information through the same piece of information. Alternatively, the camera application may acquire media data and Exif including private information and non-private information, respectively, through different information.

Optionally, if the Exif acquired by the camera application includes private information and non-private information, the camera application may further acquire the private information from the Exif, and delete the private information included in the Exif, to obtain the private information, the Exif that does not include the private information, and the media data, respectively.

If the first image is received by the electronic device from another electronic device, the other electronic device may transmit the media data and the attribute information of the first image in the same manner as the camera service transmits the media data and the attribute information described above. Accordingly, the manner in which the electronic device receives the media data and the attribute information may be the same as the manner in which the camera application receives the media data and the attribute information, which is not described herein.

S502: the electronic device stores the media data and the non-private information in a first storage area and stores the private information in a second storage area.

After the electronic device acquires the private information, the non-private information, and the media data of the first image, respectively, the acquired data may be stored, for example, the electronic device may store the media data and the non-private information of the first image in the first storage area and the private information of the first image in the second storage area.

Alternatively, the first storage area may be a folder and/or a database, and the second storage area may be a folder and/or a database, and several different combinations of the first storage area and the second storage area are described below.

First kind: the first storage area is a folder and the second storage area is a folder.

The first storage area is used for storing media data and non-private data, the importance of the data is lower, the second storage area is used for storing private data, and the importance of the data is higher, so when the first storage area and the second storage area are folders, the authority levels of the first folder corresponding to the first storage area and the second folder corresponding to the second storage area are different, for example, the authority level of the first folder is lower than the authority level of the second folder, wherein the authority level is used for indicating whether the authority verification is needed or not, the authority level is high, the requirement for the access authority verification is indicated, and the authority level is low, and the requirement for the access authority verification is indicated. Optionally, the two folders may be located in the electronic device, or may also be located in the cloud, or the first folder is located in the electronic device, and the second folder is located in the cloud.

Second kind: the first storage area is a folder and the second storage area is a database.

Alternatively, the first storage area may be a folder with a lower authority level, and the second storage area may be a privacy database. The positions of the first storage area and the second storage area are similar to the positions of the first folder and the second folder in the above embodiment, and may be located in the electronic device and/or the cloud end, which is not described herein.

Third kind: the first storage area is a database and the second storage area is a folder.

Alternatively, the first storage area may be a non-private database, and the second storage area may be a folder with a higher authority level. The positions of the first storage area and the second storage area are similar to the positions of the first folder and the second folder in the above embodiment, and may be located in the electronic device and/or the cloud end, which is not described herein.

Fourth kind: the first storage area is a database, and the second storage area is a database.

Alternatively, the first storage area may be a non-private database and the second storage area may be a private database. The positions of the privacy database and the non-privacy database are similar to the positions of the first folder and the second folder in the above embodiment, and may be located in the electronic device and/or the cloud end, which is not described herein. When the locations of the private database and the non-private database are both electronic devices, the non-private database and the private database may be databases managed through the media library.

Alternatively, the first storage area and the second storage area may be two different storage areas, for example, the first storage area is the internal memory 121 shown in fig. 1A, and the second storage area is the cloud.

Optionally, if the first storage area and/or the second storage area are cloud, the electronic device may send the corresponding data to the cloud to be stored through the cloud. For example, if the first storage area is located in the cloud end, the electronic device sends media data and non-private information of the first image to the cloud end, and the cloud end stores the received data in a first folder or a non-private database. If the second storage area is the cloud end, the electronic device sends the privacy information of the first image to the cloud end, and the cloud end stores the received data into a second folder or a privacy database. If the first storage area and the second storage area are both located in the cloud end, the electronic device can send the data stored in the first storage area and the data stored in the second storage area to the cloud end through information at different moments, and after the cloud end receives the data, the received data is stored in the corresponding storage area. In other embodiments, the electronic device may also send the media data, the non-private information, and the private information of the first image to the cloud end through the same information, where the cloud end obtains the private information and the non-private information, stores the media data and the non-private information in the first storage area, and stores the private information in the second storage area. In the following embodiments, the first storage area is a non-private database located in the electronic device, and the second storage area is a private database located in the electronic device.

In some other embodiments, the electronic device may also store the media data and the non-private information of the first media file separately, for example, store the non-private information in the first storage area, store the private information in the second storage area, store the media data in the third storage area, and the first storage area, the second storage area, and the third storage area may be located in the electronic device and/or the cloud, where the locations and types of the first storage area, the second storage area, and the third storage area are similar to those of the first storage area and the second storage area in the above embodiments, and are not described herein. Alternatively, when the electronic device is a mobile phone, the third storage area may be, for example, a gallery application installed on the mobile phone.

According to the technical scheme, the non-private information and the private information of the media file are stored separately, so that when the electronic equipment does not need to send the private information, the media data and the non-private information of the image can be acquired from the first storage area, the private information is not acquired from the second storage area, and the probability of privacy disclosure is reduced.

Two embodiments are described below with reference to fig. 6 and 7, which are two examples of the media file storage method described by the embodiment shown in fig. 5. In both examples, the image captured by the camera application of the electronic device is taken as an example.

Referring to fig. 6, a flowchart of an example of a media file storage method is provided for the embodiment shown in fig. 5.

S601: the handset 100 detects an operational behavior for the camera application.

Wherein the operational behavior is used to trigger the camera application to take an image. Taking (a) in fig. 2 as an example, this operation acts as, for example, an operation of the icon 202 of the user-triggered camera application. When the mobile phone 100 detects a trigger operation of the icon 202 for the camera application, an interface as shown in (b) of fig. 2 is displayed, and the user can perform related operations, such as selecting "photographing", or selecting "video", based on the interface as shown in (b) of fig. 2.

S602: the camera application sends a capture request to the camera service. Accordingly, the camera service receives a photographing request from the camera application.

In this example, the photographing request may include indication information indicating that the privacy information and the non-privacy information in the attribute information are separately reported, for example, indicating that the privacy information is not written in the Exif of the first image, and is separately reported.

S603: the camera service transmits privacy information and non-privacy information included in the attribute information of the first image to the camera application based on the photographing request. Accordingly, the camera application receives private information and non-private information from the camera service.

The manner in which the camera service sends the first image and the privacy information to the camera application based on the photographing request may refer to the manner in which the camera service sends the privacy information and the non-privacy information to the camera application when the photographing request includes the indication information in S501, which is not described herein.

S604: the camera application stores media data and Exif in a first storage area, and stores privacy information in a second storage area.

In the technical scheme, the camera service sends the private information and the non-private information to the camera application through different information, so that the camera application is facilitated to distinguish the two information.

Referring to fig. 7, a flowchart of another example of a media file storage method is provided for the embodiment shown in fig. 5.

S701: the handset 100 detects an operational behavior for the camera application.

The operation is similar to that in S601, and will not be described herein.

S702: the camera application sends a capture request to the camera service. Accordingly, the camera service receives a photographing request from the camera application.

In this example, the photographing request does not include instruction information for instructing to not write privacy information to the Exif of the image.

S703: the camera service transmits media data and Exif to the camera application. Accordingly, the camera application receives media data and Exif from the camera service.

The manner in which the camera service sends the privacy information and the non-privacy information of the first image to the camera application based on the capturing request may refer to the embodiment in which the camera service sends the privacy information and the non-privacy information to the camera application when the capturing request does not include the indication information in S501, which is not described herein.

S704: the camera application acquires the privacy information from the Exif and deletes the privacy information in the Exif.

Since the Exif contains the privacy information, the camera application can acquire the privacy information from the Exif and delete the privacy information in the Exif after receiving the Exif and the media data.

S705: the camera application stores media data and Exif deleting privacy information in the first storage area and stores privacy information in the second storage area.

According to the technical scheme, the camera service sends the private information and the non-private information through the same information, so that information interaction between the camera service and the camera application can be reduced.

In connection with the above embodiments and related drawings, the embodiments of the present application provide a media file sharing method, which may be implemented by using the mobile phone 100 shown in fig. 1A or other electronic devices. For example, the embodiments of the present application may be performed after performing the media file storage flow illustrated in any one of fig. 5 to 7. As shown in fig. 8, a flow chart of the method is shown.

S801: the electronic device displays a plurality of media files on a display interface of the electronic device in response to a media file sharing operation by a user based on the first application.

Wherein the plurality of media files includes a first media file. The first application is a social application installed in the electronic device, and taking (a) in fig. 3A as an example, the media file sharing operation may be an operation that a user clicks a control 302 in a display interface 301 of the social application. The electronic device upon detecting the media file sharing operation may display a plurality of media files, such as image 306, image 307, and image 308 in (c) of fig. 3A, with the first media file being, for example, image 306.

S802: the electronic device responds to the first media file selected by the user and sends first data or first resource information of the first media file through the first application.

Optionally, after the electronic device responds to the first media file selected by the user, the electronic device may further send, through the first application, first request information to a media library of the electronic device for requesting to acquire the first media file, where, taking (c) in fig. 3A and (B) in fig. 3B as an example, the first request information may be information sent by the social application when the user clicks "image 306" in the image candidate interface 305 of the social application, or the first request information may also be information sent by the social application when the user clicks "none" corresponding option 311, or clicks "complete" corresponding option 316, or clicks all options corresponding to parameters of the privacy information (including 312, 313, 314, 315) in the image candidate interface 305 of the social application.

After the media library receives the first request information, first data or first resource information of the first media file is acquired from the first storage area based on the first request information. Alternatively, the media library may retrieve the media data and the non-private information from the first storage area by invoking the first interface. In this embodiment of the present application, if the first storage area and the second storage area are databases, the electronic device sends, through the first application, first resource information for locating the first data resource, so that other electronic devices or the first application may acquire the requested data based on the first resource information. If the first storage area and the second storage area are different folders and the like, the electronic device can directly send the first data through the first application, wherein the first resource information comprises a first URI for locating the first data resource.

After the media library obtains the data or the first URI, the electronic device may send the first data or the first URI through the first application, for example, the electronic device may send the first data or the first URI through the first application to a cloud server of the first application, or the electronic device may send the first data or the first URI through the first application to other contacts.

For example, if the first application is a social application, the electronic device may send the first data or the first URI to a cloud server of the social application through the social application, so that the first data or the first URI may be obtained from the cloud server using an account of the social application. Or if the first application is an instant messaging application (e.g., a short message), the electronic device may send the first data or the first URI to a communication (e.g., a mobile phone number) corresponding to the other contact through the first application.

In this embodiment, when the data or the URI of the first media file is sent by the first application, the first data or the first URI of the first media file is sent by default, that is, the media data and the non-private information of the first media file are sent, and the private information of the first media file is not sent.

In some cases, the user may wish the electronic device to send the privacy information of the first media file together. For example, when the mobile phone is replaced, the album in the old mobile phone is to be synchronized with the new mobile phone, and when the old mobile phone sends the content of the album, for example, when cloning the mobile phone, the old mobile phone can send the privacy information of the image included in the album together; or when the images in the mobile phone are stored in a personal computer (personal computer, PC) or a cloud, the mobile phone can send the privacy information of the images together when sending the images; or when the mobile phone distributes and shares the image to other electronic equipment, the mobile phone can share the privacy information of the image, wherein the distributed sharing means that the mobile phone can display the content currently displayed by the mobile phone to the other electronic equipment in real time, and the other electronic equipment is the electronic equipment which is authorized by the mobile phone; or when the image is sent to the appointed contact person through the short message application, the mobile phone can send the privacy information of the image together when the image is sent through the short message application; or, when classifying the images in the gallery by combining the small program with the map, the mobile phone can send the privacy information of the images together when sending the images by the small program. Thus, optionally, the electronic device may also determine, before sending the data of the first media file or the first URI via the first application, whether the corresponding condition is met to determine whether to send the privacy information. For example, if the first condition is met, the electronic device may send the first data or the first URI through the first application, i.e., not send the privacy information of the first media file through the first application; or if the second condition is met, the electronic device may send the second data or the second URI of the first media file through the first application, where the data corresponding to the second data or the second URI includes the privacy information, the non-privacy information and the media data of the first media file, that is, the privacy information of the first media file may be sent through the first application.

Alternatively, the first condition includes, for example: the importance evaluation value of the media file is greater than or equal to a first value, and/or the media library receives first indication information, and/or parameters of the first request information, which do not include privacy information, and/or first operation of the user based on the electronic equipment is detected, and/or the electronic equipment does not detect the operation of the user based on the electronic equipment in a first duration. Wherein the first indication information and the first operation may indicate that the privacy information is not transmitted.

For example, the electronic device may analyze the first media file to determine an importance rating of the first media file to determine whether the first condition is satisfied based on the importance rating. If the importance evaluation value of the first media file is greater than or equal to the first value, which indicates that the first media file is important, sharing the privacy information of the first media file may cause a greater potential safety hazard, so the electronic device may not send the privacy information of the first media file. For example, the data sent by the electronic device in S802 may not include the privacy information of the first media file, or the electronic device may not include the privacy information of the first media file in the data corresponding to the first URI sent in S802.

Optionally, the electronic device may analyze the first media file based on the shooting scene of the first media file and/or shooting content to determine an importance assessment value of the first media file. For example, the shooting scene of the first media file is a living room or a bedroom, and the privacy information of the first media file may include shooting location information of the first media file that is a home address of the user, which is easy to cause a potential safety hazard. At this time, the electronic device may determine that the importance evaluation value of the first media file is higher, and may not share the privacy information of the first media file, so as to ensure personal safety of the user.

That is, the electronic device may determine whether to send the privacy information of the media file according to the importance of the media file, so as to reduce the probability of disclosure of the privacy information of the important media file and improve the information security.

The electronic device may also determine whether the first condition is met based on whether the first indication information is received by the media library. After the electronic device responds to the first media file selected by the user, a first preset option for indicating whether to send the private information may be displayed on the display interface, for example, as shown in (a) in fig. 3B, where the first preset option includes: the option 309 corresponding to "send privacy information" and the option 310 corresponding to "do not send privacy information" send first indication information to the media library through the first application when the user selects the option 310, so if the indication information received by the media library is the first indication information, it is determined that the first condition is satisfied.

The electronic device may also determine whether the first condition is satisfied according to whether the parameter of the privacy information is included in the first request information. After the electronic device responds to the first media file selected by the user, a second preset option may be displayed on the display interface, for example, as shown in (B) in fig. 3B, where the second preset option includes: the first application may transmit first request information of parameters not including privacy information when the user selects the "none" corresponding option 311, the "photographing time" corresponding option 312, the "lens parameter" corresponding option 313, the "photographing position information" corresponding option 314, the "device model" corresponding option 315, and the "completion" corresponding option 316. It is determined that the first condition is satisfied if the media library receives first request information that does not include parameters of the privacy information.

The electronic device may also determine whether the first condition is met based on whether a user is detected based on a first operation of the electronic device. The first operation is, for example, a click operation for a screen input of the electronic device, or other preset operation. For example, referring to (c) in fig. 3A, after the user selects the image 306, the electronic device displays a preview image of the image 306, and if the electronic device detects a click operation for the preview image, it is determined that the first condition is satisfied.

The electronic device may also determine whether the first condition is met based on whether a user operation based on the electronic device is detected. For example, after the electronic device displays the preview image of the image 306, if the electronic device does not detect any operation of the user based on the electronic device within a first period of time, at which time the user may default to not want to share the privacy information, it is determined that the first condition is satisfied.

That is, the electronic device judges whether the private information needs to be sent according to the requirement of the user, so that the disclosure of the private information which the user does not want to share can be avoided, the processing process of the electronic device meets the requirement of the user, and the sharing experience of the user is facilitated to be improved.

The first condition is described above and the second condition is described below. Optionally, the second condition includes, for example, one or more of: the importance evaluation value of the first media file is smaller than the first value, and/or the second indication information is received and the first application is successfully checked, and/or the first request information comprises parameters of privacy information and the first application is successfully checked, and/or the second operation of the user based on the electronic equipment is detected and the first application is successfully checked. The second indication information and the second operation may indicate sending the privacy information, and the parameter of the privacy information may indicate the privacy information that needs to be acquired.

For example, the electronic device may analyze the first media file to determine an importance rating of the first media file to determine whether the second condition is satisfied based on the importance rating. If the importance rating of the first media file is less than the first value, indicating that the importance of the first media file is low, the electronic device may send privacy information for the first media file. For example, the data transmitted by the electronic device in S802 may include the privacy information of the first media file, or the electronic device may include the privacy information of the first media file in the data corresponding to the first URI transmitted in S802. For example, the shooting scene of the first media file is a mall, and even if the privacy information of the first media file is shared, the user is not adversely affected, and at this time, the electronic device can determine that the importance evaluation value corresponding to the first media file is low, and can share the privacy information.

The electronic device may also determine whether the second condition is met based on whether the second indication information is received by the media library. For example, referring to (a) in fig. 3B, when the user selects option 309, the electronic device transmits second indication information to the media library through the first application, and thus determines that the second condition is satisfied if the indication information received by the media library is the second indication information.

The electronic device may also determine whether the second condition is satisfied according to whether the parameter of the privacy information is included in the first request information. For example, referring to (B) in fig. 3B, when the user selects the option 312 corresponding to "photographing time" from the parameters of the privacy information, the parameter of the privacy information carried by the first request information that the first application may send is the photographing time. And thus determines that the second condition is satisfied if the photographing time is included in the first request information received by the media library.

The electronic device may also determine whether a second condition is met based on whether a second operation of the user based on the electronic device is detected. The second operation is, for example, a double click operation for a screen input of the electronic device, or other preset operation. For example, referring to (c) in fig. 3A, after the user selects the image 306, the electronic device displays a preview image of the image 306, and if the electronic device detects a double click operation for the preview image, it is determined that the second condition is satisfied.

The electronic device may also determine whether the second condition is met based on whether the application is verified as successful. When the first application is installed (or in a subsequent use process), a user can determine whether privacy information can be sent by the first application according to actual requirements, and taking the electronic device (the mobile phone 100) as an android as an example, the first application declares permission to access the privacy database in android menu. For example, if the user determines that private information can be sent through the first application, the first application may be authorized, and if the user determines that private information cannot be sent through the first application, the first application is not authorized. Optionally, when the user authorizes the first application, the authorization type may also be specified, for example, the parameters specifying the privacy information that the first application may send include only the shooting time. When the first application is checked, whether the first application is checked successfully or not can be determined by whether the first application is authorized, for example, the first application is authorized by a user, the first application is determined to be checked successfully, if the first application is not authorized by the user, the first application is determined to be checked to fail, and when the first application is determined to be checked successfully, the second condition is determined to be met. Wherein the first application having been authorized by the user includes the first application being authorized to access the privacy database or the first application being authorized to send one or more parameters of the privacy information.

The electronic device may also determine whether the second condition is met based on whether the second indication information is received by the media library and whether the application is verified to be successful. For example, referring to fig. 3B (a), when the user selects the option 309 corresponding to "send privacy information", the first application may send the second indication information, and when the media library receives the second indication information, the first application may also be checked, and if the first application is authorized to access the privacy database, or the first application is authorized to send the shooting time, it is determined that the first application check is successful, and the second condition is satisfied.

The electronic device may further determine whether the second condition is satisfied according to whether the parameter of the privacy information is included in the first request information and whether the application is verified successfully. For example, referring to (B) in fig. 3B, when the user selects the option 312 corresponding to "shooting time" from the parameters of the privacy information, the parameter of the privacy information carried by the first request information that can be sent by the first application is shooting time, when the electronic device receives the first request information, the first application is checked, if the first application is authorized to access the privacy database, or the first application is authorized to send the shooting time, the check is determined to be successful, and the second condition is satisfied. If the first application is authorized to send the shot parameters, a verification failure is determined.

The electronic device may also determine whether the second condition is met based on whether it is detected that the user is successful based on a second operation of the electronic device and whether the application is verified. The second operation is, for example, a double click operation for a screen input of the electronic device, or other preset operation. For example, referring to fig. 3A (c), after the user selects the image 306, the electronic device displays a preview image of the image 306, and if the electronic device detects a double click operation for the preview image, the first application may also be checked, and if the check is successful, it is determined that the second condition is satisfied.

Alternatively, if the check on the first application fails, a rejection message is returned to be sent through the first application (e.g., error is returned through the first application). That is, when the electronic device determines that the private information needs to be sent according to the requirement of the user, the electronic device can also check the first application, if the first application is checked successfully, the electronic device can send the private information, so that the processing process of the electronic device meets the requirement of the user, and meanwhile, the security in the information sharing process can be further improved, and the sharing experience of the user is facilitated to be improved.

Optionally, when it is determined that the second condition is met, media data and non-private information of the first media file may be acquired from the first storage area through the media library, and private information of the first media file may be acquired from the second storage area through the media library, and the acquired media data, private information and non-private information may be sent through the first application. Alternatively, the media data and the non-private information may be retrieved from the first storage area by invoking the second interface through the media library.

As an example, the media data stored in the first storage area is, for example, a first image, the non-private information stored in the first storage area is, for example, an Exif that does not include private information, the electronic device may copy the first image and the Exif that does not include private information corresponding to the first image from the first storage area through the media library, and copy the private information corresponding to the first image from the second storage area, the media library may insert the private information into the Exif that does not include private information, obtain the Exif that includes private information, obtain a new first image (for example, a second image), wherein the Exif corresponding to the new first image is the Exif that includes private information, and send the second image through the first application, or send a URI (for example, a second URI) of the second image through the first application. Alternatively, the media library may delete the new first image after a preset period of time. It should be noted that determining that the first condition and the second condition are satisfied may be decoupled, for example, determining whether the first condition and the second condition are satisfied may correspond, for example, determining that the first condition is satisfied if the importance rating of the first media file is greater than or equal to the first value, and determining that the second condition is satisfied if the importance rating of the first media file is less than the first value. Alternatively, it may be non-corresponding to determine whether the first condition and the second condition are satisfied, for example, if the importance evaluation value of the first media file is greater than or equal to the first value, it is determined that the first condition is satisfied, but the importance evaluation value of the first media file is smaller than the first value, not as a determination condition for determining whether the first condition is satisfied, but a parameter for determining whether the second instruction information is received or whether the privacy information is included in the received first request information is included as a determination condition for determining whether the second condition is satisfied.

In some embodiments, the media data and attribute information of the first media file sent by the electronic device through the first application are media data and attribute information stored by the electronic device, rather than a snapshot or a screenshot, and privacy information can be hidden according to user requirements while ensuring image quality definition of the first media file.

According to the technical scheme, the electronic equipment can determine whether to send the private information according to the importance of the media file or the user requirement, the probability of privacy information disclosure of the important media file can be reduced, and when the private information is determined not to be sent, only the media data and the non-private information of the image can be obtained and sent through the media library without obtaining the private information of the media file by means of separately storing the private information and the non-private information in the attribute information, so that the probability of privacy disclosure is further reduced.

Two embodiments are described below by way of 9 and 10, which are two examples of combining fig. 5 and 8, in which the first storage area and the second storage area are databases managed by a media library, for example, to store images taken by a camera application of an electronic device.

Referring to fig. 9, a flowchart of an example of a media file storage and sharing method is provided for the embodiment shown in fig. 5 and 8.

S901: the handset 100 detects an operational behavior for the camera application.

S902: the camera application sends a capture request to the camera service. Accordingly, the camera service receives a photographing request from the camera application.

The shooting request includes indication information, which indicates that the privacy information and the non-privacy information in the attribute information are separately reported, for example, the indication information is not written in the Exif of the first image and is separately reported.

S903: the camera service sends a first photographing result to the camera application through the first information, and the camera service sends a second photographing result to the camera application through the second information. Accordingly, the camera application receives the first photographing result and the second photographing result from the camera service.

Wherein the first photographing result includes, for example, media data and non-private information of the first image, the second photographing result includes private information of the first image, and the private information includes, but is not limited to, the following information:

geographic location information, namely longitude and latitude information;

a mobile phone model;

shooting time;

lens parameters.

S904: the camera application stores media data to a gallery application (not shown in fig. 9), stores non-private information to a non-private database, and stores private information to a private database.

Wherein the non-private information and the private information are stored in a non-private database and a private database, for example, the camera application creates a record in the non-private database, writes the non-private information, and creates a record in the private database, writes the private information, and the non-private information is, for example, exif which does not contain the private information.

S905: the mobile phone 100 detects a media file sharing action for the first application.

The media file sharing behavior may include, for example, the behavior that the control 402 in (a) of fig. 4 is triggered, or the control 302 in (a) of fig. 3A is triggered.

S906: the first application sends first request information to the media library. Accordingly, the media library receives first request information from the first application.

The first request information is used for requesting to acquire the first image, where the first request information may include parameters of the privacy information, if the first request information does not include parameters of the privacy information, S907 is executed, and if the first request information includes parameters of the privacy information, S908 is executed.

S907: the media library sends a first URI of the first image to the first application.

The data corresponding to the first URI comprises a first image stored in the gallery application and non-private information corresponding to the first image stored in the non-private database.
