And the SE is used for processing the confidential information and internally provided with an independent memory and a processor, so that the system security is ensured.

A Wireless Transceiver (WTR) mainly includes a mixer, a transformer, and a variable gain amplifier. The short-distance communication chip comprises Wi-Fi, Bluetooth, NFC, a radio, a Global Positioning System (GPS) and the like. The Codec chip is used for processing a voice signal, converting an original voice signal in the nature into a digital voice signal, and outputting a voice/audio signal (64kbps or higher) through Pulse Code Modulation (PCM) processing for further processing by the main SOC. The PMIC is also called a power management unit and is used for generating voltage and clock required by the work of other chips to realize power management.

The NPU can realize the intelligent cognition and other applications of the terminal, such as: image recognition, face recognition, speech recognition, text understanding, and the like.

The external memory interface can be used for connecting an external memory card, such as a Micro SD card, so as to realize the storage capability of the expansion terminal. The external memory card communicates with the processor through the external memory interface to realize the data storage function. For example, files such as music, video, etc. are saved in an external memory card.

In some embodiments, the audio module may be disposed in the processor, or a portion of the functional modules of the audio module may be disposed in the processor.

It is to be understood that the illustrated structure of the embodiments of the present application does not constitute a specific limitation to the terminal. In other embodiments of the present application, the terminal may include more or fewer components than shown, or some components may be combined, some components may be split, or a different arrangement of components may be used. The illustrated components may be implemented in hardware, software, or a combination of software and hardware. The structures of the respective terminals in fig. 1 may be the same or different.

In the network architecture shown in fig. 1, media data can be shared among a plurality of terminal devices. The media data may be video, audio, or image, etc. The method of sharing images is described with reference to fig. 3.

Fig. 3 is a schematic interface diagram of a group of terminals in an embodiment of the present application, which illustrates an interface diagram of a terminal of a sharer when sharing an image. As shown in fig. 3, interface 301, interface 302, interface 303, and interface 304 are included. The image taken by the user through the terminal is stored in the local storage space of the terminal, and the interface corresponding to the local storage space is shown as 301. Referring to interface 301, a user views a previously captured image in the local storage space of the terminal. When image sharing is needed, a selection button at the upper right of the interface 301 is clicked, so that the terminal jumps to the interface 302. In the interface 302, each image is in a state in which it can be selected. After the user clicks a certain image, the image is in a selected state. Further, after the user selects an image to be shared, as shown in the interface 303, a sharing button appears at the bottom of the interface. The user clicks the share button, so that the terminal jumps to the interface 304, and the selectable sharing mode is displayed in the interface 304. Wherein, the optional sharing modes include but are not limited to: mail sharing, social application sharing, bluetooth sharing, Wi-Fi sharing, and the like. The user can select a sharing mode suitable for the user to share the image according to the preference of the user or the current network environment.

It should be noted that the description of the image sharing method and the related interface shown in fig. 3 is only an exemplary illustration. Different terminals may have different operation methods and interface displays for image sharing.

In one possible scenario, the terminal also typically has image processing functions, such as: and performing figure beautifying processing and the like on the image. Therefore, before the user performs image sharing, for example: in the interface 303 shown in fig. 3, a beauty button may be further included. And when the user clicks the figure beautifying button, the user enters a figure beautifying interface, so that the user can beautify the image according to the requirement of the user. Then, aiming at the beautified image, the user carries out manual sharing.

In one possible scenario, the terminal may also support album creation functions. In the interface 302 shown in FIG. 3, a user may select multiple images. The terminal can make a plurality of images selected by the user into an album, so that the user can share the album manually.

However, in the above image sharing methods, the terminal is required to capture the image first and store the image in the local storage space. And then, the user selects the image to be shared from the local storage space to perform manual sharing. It can be understood that, when a user uses a terminal to take a picture, the same scene may be taken multiple times in order to ensure that a higher quality image is taken, which results in a large number of similar images being stored in the local storage space. For example, in the interface 301 shown in fig. 3, a plurality of relatively similar images are stored for each scene. Therefore, on one hand, a large number of images are stored in the local storage space of the terminal, and the local storage space is wasted; on the other hand, when the user shares images, the user needs to manually select an image with high shooting quality from a large number of similar images, and great effort of the user needs to be consumed.

In a possible implementation, image scoring software may be installed in the terminal, and is used for scoring the images according to the image browsing time and frequency. Illustratively, images that are browsed more frequently are scored higher, and images that are browsed less frequently are scored lower. The user can manually delete the low-score images according to the scoring result of the image scoring software on each image. Through the above process, although the repeated images or the low-quality images in the terminal can be reduced to a certain extent, a large number of images still need to be temporarily stored in the local storage space, and the repeated images or the low-quality images can be deleted only after the user regularly counts the browsing behavior, so that the failure is poor.

The image scoring software is limited to scoring the images in the terminal, so that the repeated images or low-resolution images in the terminal can be reduced to a certain extent. In a scene where multiple persons are going to travel or meet, multiple terminals may shoot the same scene at the same time, so that a large number of similar images exist in the multiple terminals. Therefore, when image sharing is performed among a plurality of terminals, a large number of images of similar scenes may still exist among images shared with each other.

In addition, although most terminals support image processing functions, such as: the above-mentioned figure beautifying processing, album making and the like. However, since the image processing capabilities of different terminals are different, and even the difference in image processing capabilities between some terminals is large, the quality of images shared by different terminals is different, and the image effect of the shared images cannot be optimal.

In order to solve at least one of the above problems, embodiments of the present application provide a method for sharing media data, which does not need to store a large amount of similar media data in a local storage space of a terminal, and avoids wasting local storage resources of the terminal; in addition, the user does not need to screen the media data to be shared from a large amount of similar media data, but the terminal intelligently shares the media data according to the preset sharing rule, so that a large amount of screening energy of the user is not consumed.

The technical solution of the present application will be described in detail by specific examples. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

Fig. 4 is a schematic flowchart of a media data sharing method according to an embodiment of the present disclosure. As shown in fig. 4, the method of this embodiment includes:

s401: the first terminal shoots to obtain media data and sends the media data to the second terminal, wherein the media data is temporarily stored or not stored in the local of the first terminal before being sent to the second terminal.

S402: the second terminal sends the media data to a shared terminal according to a sharing rule corresponding to the first terminal, the shared terminal is a terminal in the media data sharing system, and the sharing rule is used for indicating a corresponding relation between characteristics of the media data and an identifier of the shared terminal.

The method of the embodiment can be applied to the media data sharing system shown in fig. 1. The system comprises a plurality of terminals, and users corresponding to the terminals usually have certain contact, for example, the terminals of a plurality of members in a family form a media data sharing system. The terminals of a plurality of members in a certain class form a media data sharing system. The terminals of a plurality of members in a certain outbound group form a media data sharing system. The members in the media data sharing system can share media data with each other.

The media data in this embodiment includes, but is not limited to, video data and image data. For convenience of description in the following embodiments, only image data will be described as an example.

In this embodiment, the media data sharing system includes a second terminal and at least one first terminal. Wherein the second terminal may be any one terminal in the system. The first terminal is a terminal other than the second terminal in the system. In this embodiment, the first terminal obtains the media data by shooting, and sends the media data to the second terminal, so as to implement the sharing action of the media data by means of the second terminal. Wherein the media data is temporarily stored or not stored locally at the first terminal before being transmitted to the second terminal.

Optionally, whether the media data is temporarily stored locally at the first terminal, and the storage duration may be set by the user, and the terminal may recommend the storage mode to the user according to the current network environment, and the user selects and confirms the storage mode.

Optionally, before or after the first terminal obtains the media data through shooting, the first terminal receives a storage mode instruction input by a user, where the storage mode instruction is used to indicate a storage mode of the media data in a local storage space of the first terminal, and the storage mode is temporary storage or non-storage. Optionally, the storage mode instruction may further include a temporary storage duration. Correspondingly, if the storage mode is temporary storage, after the first terminal obtains the media data by shooting, the media data is temporarily stored locally, then the media data is sent to the second terminal, and after the temporary storage time length is reached, the media data is deleted from the local storage space. And if the storage mode is not storage, the first terminal does not locally store the media data after shooting the media data, and directly sends the media data to the second terminal. With regard to the input mode of the storage mode command, several possible modes are exemplified below.

In one possible mode, after the first terminal obtains the media data through shooting, the first terminal displays a first query interface to a user. In the first query interface, the user may select to temporarily store the media data or not, and when the user selects the temporary storage, the time length of the temporary storage may be further set in the first query interface.

In another possible approach, the second query interface is presented to the user before the first terminal captures the media data (e.g., after detecting that the user opens the camera application). In the second query interface, the user may select a storage mode of the media data, for example, temporary storage or non-storage, and may further set a duration of the temporary storage after the user selects the temporary storage mode. Further, the user may set an effective time period of the storage mode in the second query interface. For example: the user can set the images shot between 8:00 and 16:00 of the day to adopt the storage mode.

In another possible mode, before or after the first terminal obtains the media data through shooting, a third query interface is displayed to the user, and in the third query interface, a storage mode is recommended to the user in combination with the current network environment of the first terminal. For example, "it is recommended that you choose not to store because your current network environment is a local area network to save storage space" or "it is recommended that you choose to temporarily store because your current network environment is a non-local area network to save your traffic" is displayed in the third query interface, so that the user can make a selection confirmation according to the above-mentioned recommended contents.

It should be understood that the present embodiment does not specifically limit the query interface and the content of the query interface, and the description in the above example is only an exemplary description.

In the embodiment of the present application, the term "not storing" means: the first terminal sends the media data to the second terminal immediately after shooting the media data, and the first terminal does not store the media data in the local storage space. The temporary storage means that: after the first terminal obtains the media data through shooting, the media data are stored in the local storage space for a certain time, and after the media data are sent to the second terminal, the media data are deleted from the local storage space. The certain duration may be a preset fixed duration, or may be any duration, and this embodiment is not particularly limited. The local storage space may be a non-operating internal memory supported by the first terminal itself, or may be an external memory of the first terminal, for example: SD cards, and the like.

It can be understood that "the media data is temporarily stored locally at the first terminal" may be applicable to a scenario in which the first terminal performs centralized sharing on the media data, and "the media data is not stored locally at the first terminal" may be applicable to a scenario in which the first terminal performs real-time sharing on the media data. In the following description several possible embodiments are described.

In one possible implementation, after the first terminal obtains the media data by shooting, the first terminal directly sends the media data to the second terminal without storing the media data in the local storage space. The embodiment is suitable for real-time sharing scenes.

In another possible implementation manner, after the first terminal obtains the media data through shooting, the first terminal may temporarily store the media data in the local storage space. After the first terminal detects that the tour is finished or the party is finished (for example, the first terminal does not shoot any media data within a preset time length, or the first terminal receives an instruction input by a user and used for indicating the tour is finished or the party is finished), the first terminal sends the temporarily stored media data to the second terminal. Then, the first terminal deletes these temporarily stored media data from the local storage space.

Or, after the second terminal detects the end of the tour or the end of the party (for example, the first terminal sends a message indicating the end of the tour or the end of the party to the second terminal, or a user of the second terminal inputs a message indicating the end of the tour or the end of the party to the second terminal), the second terminal sends a media data collection instruction to the first terminal, so that the first terminal sends the temporarily stored media data to the second terminal. Then, the first terminal deletes these temporarily stored media data from the local storage space. The embodiment is suitable for centralized sharing scenes, and although the local storage space of the first terminal can be occupied temporarily, the local storage space of the first terminal can be occupied for a short time, and long-time occupation and waste can not be caused.

In another possible implementation manner, a real-time sharing manner or a centralized sharing manner may be determined according to a network connection manner between the first terminal and the second terminal.

Illustratively, after the first terminal obtains the media data through shooting, it is detected whether the first terminal and the second terminal are located in the same local area network, including but not limited to a Wi-Fi local area network, a bluetooth connection, an NFC connection, and the like. For example, the first terminal obtains its own network environment, and if it is in a local area network, it may determine whether the second terminal is also in the local area network by using a device discovery technique.

In a possible scenario, if the first terminal determines that the first terminal and the second terminal are located in the same local area network, the first terminal does not store the media data in the local storage space, but directly sends the media data to the second terminal. The scene is a real-time sharing scene, and the media data are transmitted through the local area network, so that the sharing timeliness is guaranteed, and the mobile data flow of the terminal is avoided being consumed.

In another possible scenario, if the first terminal determines that the first terminal and the second terminal are not located in the same lan, the first terminal temporarily stores the media data locally, and when detecting that the first terminal and the second terminal are located in the same lan after the temporary storage, the first terminal sends the media data to the second terminal and deletes the media data locally. The scene is a centralized sharing scene, and the media data is transmitted through the local area network, so that the mobile data flow of the terminal is avoided being consumed.

Of course, the two scenario descriptions above are merely exemplary illustrations. Under the condition of not considering the mobile data traffic, even if the first terminal determines that the first terminal and the second terminal are not located in the same local area network, a real-time sharing mode can be adopted.

In this embodiment, the second terminal is configured to send the media data to the corresponding shared terminal according to the sharing rule corresponding to the first terminal. The second terminal may also be referred to as "arbitration terminal", "service terminal". For example, it is assumed that the media data sharing system includes 5 terminals, which are terminal a, terminal B, terminal C, terminal D, and terminal E, respectively. Wherein, the terminal C is used as the second terminal, and the other terminals are used as the first terminals. When the terminal A needs to share the shot image with the terminal D, the terminal A sends the image to the terminal C after the terminal A obtains the image. And the terminal C determines that the image needs to be shared to the terminal D according to the sharing rule of the terminal A, and then the terminal C sends the image to the terminal D. In the sharing process, the terminal a is called a sharing terminal, and the terminal D is called a shared terminal. It can be understood that, in one sharing, the sharing terminal may be the first terminal or the second terminal, and the shared terminal may be the first terminal or the second terminal. For example: the terminal A can share the image with the terminal C, the image can also be shared with the image D, and the terminal C can share the image with the terminal E. In some scenarios, there may be a plurality of shared terminals in one sharing, for example, the terminal a shares a certain image to the terminals C, D and E simultaneously.

It should be noted that, in the embodiment of the present application, the sharing terminal and the shared terminal are peer-to-peer. The first terminal can share the image for other terminals, and can also receive other terminals including the image shared by the second terminal. The second terminal can receive the image shared by the first terminal and sends the received image to the corresponding shared terminal according to the sharing rule; the second terminal may also share the image captured by itself with the first terminal, for example, in the above example, when the terminal C is used as the second terminal, the terminal C may also send the image to the corresponding shared terminal according to the sharing rule defined by itself. That is to say, both the first terminal and the second terminal can be used as sharing terminals and also can be used as shared terminals.

In a possible implementation manner, the second terminal is a terminal with the best performance in the media data sharing system. Wherein the performance of the terminal may be measured by indicating a capability as follows: shooting capabilities, image processing capabilities, security capabilities, etc. As will be appreciated, the shooting capability refers to the capability of the terminal to shoot media data, and is generally related to the following factors or parameters: pixels, resolution, sensors, lenses, apertures, anti-shake, chips, etc. Image processing capability refers to the ability of a terminal to beautify the processing of media data, and is generally related to the following factors or parameters: NPU, GPU, rendering capability, etc. Security capabilities refer to the ability of a terminal to protect the privacy of media data, and are generally related to the following factors or parameters: encryption algorithms, network security parameters, etc.

Optionally, when the terminals in the media data sharing system are terminals of the same brand, each terminal may negotiate autonomously to determine which terminal is used as the second terminal. When each terminal in the media data sharing system is of a different brand, a user corresponding to each terminal may negotiate which terminal is designated as the second terminal. This embodiment is not particularly limited thereto.

For example, the second terminal stores a sharing rule corresponding to the first terminal. The sharing rule is used for indicating the corresponding relation between the characteristics of the media data and the identifier of the shared terminal. The characteristics of the media data may include, but are not limited to: a photographing characteristic of the media data, a content characteristic of the media data, and the like. The photographing characteristics may be a photographing time, a photographing place, and the like. The content feature may be a type of the photographing content, for example: the shot content is of landscape type, person type, animal type, or the like.

Optionally, the sharing rule includes at least one of the following: the corresponding relation between the shooting time of the media data and the identification of the shared terminal, the corresponding relation between the shooting place of the media data and the identification of the shared terminal, and the corresponding relation between the shooting content of the media data and the identification of the shared terminal.

It can be understood that sharing requirements corresponding to different users in the same scene are different, for example: a user wants to share the images of children photographed to their lovers, a user wants to share the images of animals photographed to their children, and a user wants to share the images of the outgoing group photo photographed to each of the other users in the images. It can be understood that sharing requirements of the same user in different scenes may also be different. For example: a user may wish to share images captured during the tour session with their parents in a tour scenario. The user may wish to share all images taken at the meeting location to his lovers in the meeting scene. Therefore, in this embodiment, the user of each terminal can set the sharing rule according to the sharing requirement.

In this embodiment, after receiving the media data sent by the first terminal, the second terminal sends the media data to the shared terminal according to the sharing rule corresponding to the first terminal. It can be understood that the application scenario of this embodiment is a scenario in which terminals in the media data sharing system share, and therefore, the shared terminal is also a terminal in the media data sharing system.

The second terminal sends the media data to the shared terminal according to the sharing rule of the first terminal, and the following embodiments may be provided.

In a possible implementation manner, the second terminal adopts a real-time sharing manner. That is, after receiving the media data, the second terminal immediately sends the media data to the shared terminal in real time according to the sharing rule corresponding to the first terminal. The embodiment can ensure the timeliness of sharing.

Illustratively, the second terminal obtains the characteristics of the media data according to the media data; the second terminal determines the identifier of the shared terminal corresponding to the media data according to the characteristics of the media data and the sharing rule corresponding to the first terminal; and the second terminal sends the media data to the shared terminal according to the identifier of the shared terminal.

The following description is given by way of example. Assume that the sharing rule set by the user of terminal a is: the image with the shooting time of "2019-6-1" is shared with a lover of the user (the corresponding terminal marked as D, namely the terminal D). After the terminal a captured the image on day 1/6/2019, the captured image is not stored locally in the terminal a, but is directly transmitted to the terminal C (second terminal). And after receiving the image, the terminal C acquires the shooting time of the image, and the shared terminal corresponding to the image is determined to be D as the shooting time is consistent with the shooting time in the sharing rule. Thus, the terminal C transmits the image to the terminal D.

Assume that the sharing rule set by the user of terminal B is: the images with the shooting contents of the "grassland" are shared with friends of the user (the corresponding terminal marked as E, namely the terminal E). After the terminal a takes the grassland as the object to obtain the image, the taken image is not stored locally in the terminal a, but is directly transmitted to the terminal C (second terminal). And after receiving the image, the terminal C identifies the content of the image, acquires the shooting content of the image as a grassland, and determines that the shared terminal corresponding to the image is E. Therefore, the terminal C transmits the image to the terminal E.

In another possible implementation, the second terminal adopts a non-real-time sharing mode. That is, after receiving the media data, the second terminal caches the media data, and then sends the media data to the corresponding shared terminal according to the sharing rule corresponding to the first terminal. In the embodiment, the second terminal can perform comprehensive evaluation on the received multiple media data, filter out repeated images and/or images with lower quality, and ensure high quality of sharing.

In this embodiment, the second terminal adopts a non-real-time sharing mode, and when comprehensively evaluating multiple media data, the following two evaluation modes may be adopted: the first mode is as follows: and comprehensively evaluating a plurality of media data corresponding to the same shared object, wherein the second mode comprises the following steps: and comprehensively evaluating a plurality of media data corresponding to the same characteristic. Two ways are described below.

Aiming at a first optimization mode, the second terminal acquires a plurality of historical media data sent by the first terminal; the second terminal determines at least one candidate media data corresponding to the same shared terminal from the plurality of historical media data according to the characteristics of the historical media data and the sharing rule corresponding to the first terminal; for each shared terminal, the second terminal performs screening and filtering processing on each candidate media data according to the similarity between each candidate media data and/or the quality of each candidate media data to obtain media data to be shared; and the second terminal sends the media data to be shared to the shared terminal.

Aiming at a second optimization mode, the second terminal acquires a plurality of historical media data sent by the first terminal; the second terminal determines at least one candidate media data corresponding to the same characteristic from the plurality of historical media data; for each feature, the second terminal performs screening and filtering processing on each candidate media data according to the similarity between each candidate media data and/or the quality of each candidate media data to obtain media data to be shared; and the second terminal sends the media data to be shared to the shared terminal according to the sharing rule corresponding to the first terminal.

The following is exemplified in connection with two scenarios.

In a possible scenario, in a scenario that a user of a terminal a goes for a trip, the user of the terminal a sets a sharing rule as follows: shooting the image of the child and sharing the image to a lover of the child (a corresponding terminal marked as D, namely a terminal D); the images of the photographed scenery are shared with friends of the user (the corresponding terminal marked with E, namely the terminal E). Then, after the terminal a captures an image during the outgoing trip, the captured image is not stored locally in the terminal a, but is directly transmitted to the terminal C (second terminal). And after receiving the image, the terminal C caches the image. After the tour is finished (for example, the terminal C does not receive the image sent by the terminal a within a preset time period, or the terminal a sends a message for indicating the end of the tour to the terminal C), the terminal C obtains a plurality of history images sent by the terminal a from the cache, and shares the history images according to the sharing rule of the terminal a after comprehensively optimizing the history images.

If the first optimization mode is adopted, the terminal C analyzes each history image according to the two sharing rules of the terminal a to obtain the features of each history image, for example: it is determined which images have contents related to children and which images have contents related to scenery. Thus, the terminal C determines candidate images to be shared with the terminal D and candidate images to be shared with the terminal E from the history images. It will be appreciated that repeated, similar or lower quality images may be included in the candidate images. Therefore, the terminal C may also perform filtering processing on each candidate image according to the similarity and/or quality between the candidate images corresponding to the terminal D to remove the repeated, similar, and low-quality images. Therefore, the terminal C takes the remaining images after the screening as images to be shared with the terminals D, and sends the images to the terminals D. Similarly, the above-described filtering process may be performed for each candidate image corresponding to the terminal E.

If the second optimization method is adopted, the terminal C analyzes the plurality of history images sent by the terminal a, determines the features of each history image, and obtains candidate images corresponding to the same feature, for example: and determining the shooting content as a candidate image of a child, and determining the shooting content as a candidate image of a landscape. For candidate images with shot contents of children, the terminal C performs screening and filtering processing on the candidate images according to the similarity and/or quality among the candidate images so as to remove repeated, similar and low-quality images. Similarly, the above-described filtering process may be performed for candidate images whose captured contents are scenic. Therefore, the terminal C takes the remaining image subjected to the screening process as an image to be shared. And then, according to the two sharing rules of the terminal A, sending the image to be shared to the corresponding terminal to be shared.

In another possible scenario, in a scenario where users corresponding to the terminal A, B, C, D, E meet, users corresponding to each terminal all set a sharing rule as follows: and sharing the image to the members in the image. Then, after the terminal A, B, D, E captures the captured image, the captured image is not stored locally in itself, but is directly transmitted to the terminal C (second terminal). And after receiving the images sent by each terminal, the terminal C caches the images.

After the party is finished (for example, the terminal C does not receive the images sent by other terminals within a preset time period, or other terminals send a message for indicating the end of the party to the terminal C, or a user of the terminal C inputs a message for indicating the end of the party to the terminal C), the terminal C acquires a plurality of history images sent by each terminal from the cache. The terminal C analyzes each history image according to the sharing rule to obtain the features of each history image, for example: who the people in each image have is determined. Thus, the terminal C determines, from the history images, a candidate image to be shared with the terminal a, a candidate image to be shared with the terminal B, a candidate image to be shared with the terminal D, and an image to be shared with the terminal E.

It can be understood that, in a meeting scene, there may be a case where different terminals shoot the same person at the same time, and therefore, the candidate images corresponding to the terminals may include repeated, similar, or low-quality images. Therefore, the terminal C may also perform filtering processing on each candidate image according to the similarity and/or quality between the candidate images corresponding to the terminal a to remove duplicate, similar, and lower-quality images. Therefore, the terminal C takes the remaining images after the screening as images to be shared with the terminals a, and sends the images to the terminals a. Similarly, the candidate images corresponding to the terminal B, the terminal D, and the terminal E may be subjected to the above-mentioned filtering process and then sent to the corresponding shared terminals.

The method for sharing media data provided by the embodiment comprises the following steps: the first terminal shoots to obtain media data and sends the media data to the second terminal; and the second terminal sends the media data to the shared terminal according to the sharing rule corresponding to the first terminal. Through the process, the first terminal does not need to store a large amount of similar media data in the local storage space for a long time, and waste of local storage resources of the terminal is avoided. Furthermore, the media data are intelligently shared through the second terminal according to the sharing rule preset by each first terminal, so that on one hand, a user of the first terminal is not required to manually screen out the media data to be shared from a large amount of similar media data, and a large amount of screening energy of the user is not consumed; on the other hand, the second terminal intelligently shares according to the sharing rule of the first terminal, namely the second terminal is authorized by the first terminal, so that privacy disclosure and potential safety hazards are avoided, and the safety of the media data sharing process is guaranteed.

Further, on the basis of the foregoing embodiments, the sending, by the second terminal, the media data to the shared terminal may specifically include:

Wherein the image processing comprises at least one of: the method comprises the steps of carrying out picture beautifying processing on images, making a plurality of images into a dynamic photo album, making a plurality of images into videos, adding special effects to the videos, adding audio to the videos and the like.

It can be understood that, in an actual application scenario, the second terminal is usually a terminal with excellent performance in the media data sharing system, and has excellent image processing capability. Therefore, in this embodiment, each media data to be shared is image-processed by the second terminal, on one hand, the advantages of the high-performance terminal can be fully utilized to improve the image processing effect of each media data, and on the other hand, the image processing burden of each first terminal can be reduced.

In a possible implementation manner, after the second terminal sends the media data after the image processing to the shared terminal, the method may further include:

and the second terminal sends the media data after the image processing to the first terminal for shooting the media data. Accordingly, the first terminal can locally save the media data after the image processing by the second terminal. Because the second terminal filters the media data shot by the first terminal, the first terminal only needs to store the images with high quality after the filtering processing, and the local storage space of the first terminal is not wasted.

Alternatively, the first and second electrodes may be,

and the second terminal uploads the media data after the image processing to a cloud album, so that the first terminal watches the media data through the cloud album. In this way, the first terminal does not need to locally store the media data after the image processing, and the local storage space of the first terminal is not wasted.

In the embodiments, after the first terminal obtains the media data through shooting, the first terminal sends the media data to the second terminal through network connection. In another possible implementation manner, after the first terminal obtains the media data through shooting, the media data may be saved in a cloud album. And then, the second terminal acquires the media data from the cloud album and sends the media data to the shared terminal according to the sharing rule of the first terminal. The media data are stored in the cloud album, the media data do not need to be stored in the local storage space of the first terminal, and waste of the local storage space of the first terminal is avoided.

Illustratively, after the media data are obtained by shooting, the first terminal stores the media data in a cloud album in a cloud server. And the cloud server performs screening processing and image processing on the media data, and shares the processed media data to the shared terminal according to a sharing rule. Meanwhile, the cloud server stores the processed media data in a cloud album, each terminal can browse each media data in the cloud album, and each terminal can select the media data which is interested by the terminal to download to a local storage. Thus, the waste of the local storage space of each terminal is avoided.

Fig. 5 is an interaction diagram of a media data sharing method according to an embodiment of the present disclosure. As shown in fig. 5, the method of the present embodiment includes:

s501: each terminal in the media data sharing system acquires own capability information.

Wherein the capability information comprises at least one of: shooting capability, image processing capability, security capability. The shooting capability refers to the capability of the terminal to shoot media data, and is generally related to the following factors or parameters: pixels, resolution, sensors, lenses, apertures, anti-shake, chips, etc. Image processing capability refers to the ability of a terminal to beautify the processing of media data, and is generally related to the following factors or parameters: NPU, GPU, rendering capability, etc. Security capabilities refer to the ability of a terminal to protect the privacy of media data, and are generally related to the following factors or parameters: encryption algorithms, network security parameters, etc.

S502: each terminal sends the own capability information to other terminals in the media data sharing system; and each terminal negotiates and determines a terminal serving as the second terminal and a terminal serving as the first terminal according to the self capability information and the received capability information of other terminals.

S501 and S502 describe a process in which each terminal negotiates to determine a first terminal and a second terminal. Illustratively, the terminals in the media data sharing system are connected through a wide area network or a local area network. Each terminal broadcasts its own capability information to other terminals. In this way, each terminal calculates the performance score of each terminal based on its own capability information and the received capability information of the other terminals, and the terminal with the highest performance score is used as the second terminal, and the other terminals except the second terminal are used as the first terminal in the system. The performance score may be calculated by a method of scoring the three types of capability information, and then performing weighted calculation to obtain a comprehensive performance score of the terminal.

In a possible implementation manner, the specific calculation manner may be predetermined by each terminal. The same calculation mode is adopted by each terminal, so that the calculation results of the terminals are consistent.

In another possible implementation, one of the terminals may obtain the comprehensive performance score of each terminal by using the above calculation method, and determine which terminal is used as the second terminal according to the comprehensive performance score of each terminal. Then, the terminal broadcasts the determination result to other terminals.

S503: and each first terminal receives a sharing rule input by a user.

Wherein the sharing rule comprises at least one of: the corresponding relation between the shooting time of the media data and the identification of the shared terminal, the corresponding relation between the shooting place of the media data and the identification of the shared terminal, and the corresponding relation between the shooting content of the media data and the identification of the shared terminal.

And S504, each first terminal sends the sharing rule to the second terminal.

Correspondingly, the second terminal stores the sharing rule of each first terminal.

S505: and the first terminal shoots to obtain media data.

S506: and the first terminal acquires the privacy of the media data according to the media data.

S507: if the privacy degree of the media data is greater than or equal to a preset threshold value, the first terminal determines that the media data is private media data and stores the media data in a local storage space.

S508: if the privacy degree of the media data is smaller than the preset threshold value, the first terminal determines that the media data is non-private data and sends the media data to the second terminal, wherein the media data is temporarily stored or not stored locally at the first terminal.

S509: and the second terminal sends the media data to the shared terminal according to the sharing rule corresponding to the first terminal.

In this embodiment, the specific implementation of S505 to S509 is similar to the embodiment shown in fig. 4. The difference from the embodiment shown in fig. 4 is that in this embodiment, after the first terminal obtains the media data by shooting, it will first determine whether the media data is private media data. The private media data refers to media data which is private and is not desired to be shared, for example: self-timer images, self-timer videos, etc.

It can be understood that, when the media data is private media data, the media data is stored in the local storage space and is not sent to the second terminal; and when the media data is non-private media data, the media data is not stored in the local storage space and is directly sent to the second terminal. Through the process, the media data sharing safety can be guaranteed, and privacy data leakage is avoided.

In the embodiments of the present application, the transmission of the media data between the first terminal and the second terminal may be performed through a wide area network, or may be performed through a local area network, and may specifically be selected reasonably according to an actual application scenario. For example, when the distance between the first terminal and the second terminal is short, local area network transmission, such as wifi, bluetooth, NFC, etc. based short-range transmission applications, may be employed. When the distance between the first terminal and the second terminal is long, wide area network transmission, such as mobile communication network-based transmission, cloud transmission, and the like, may be employed.

In a possible implementation manner, when media data is transmitted between the first terminal and the second terminal, encrypted transmission of the media data may also be performed. Illustratively, the first terminal encrypts media data to be shared and sends the encrypted media data to the second terminal, and after the second terminal decrypts the media data, the second terminal determines a shared terminal corresponding to the media data according to a sharing rule, re-encrypts the media data, and then sends the media data to the shared terminal. The encryption process may be implemented by using an existing encryption algorithm, or media data may be transmitted based on an existing transmission protocol supporting encryption authentication, which is not described in detail in this embodiment. It can be understood that, by adopting encrypted transmission for the media data, the security of media data sharing can be further improved.
