Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, the meaning of "a plurality" is two or more unless otherwise specified.

Embodiments of the present embodiment will be described in detail below with reference to the accompanying drawings. For the convenience of understanding of the embodiments of the present application, the electronic device is a mobile phone as an example, and the principle of viewing and using media files in the mobile phone is generally described.

A large number of APPs in a handset will generate media files and will be stored in the corresponding directories. The media file may include at least one of a picture file, an audio/video file, and a document file. For example, camera APPs, chat APPs (e.g., pictures sent by friends), browser APPs, etc. may generate picture files (e.g., png,. Jpg files, etc.); music APP, recorder APP, chat APP, etc. will generate audio files (e.g., MP3, mov files, etc.); chat APPs, office APPs (e.g., office, WPS), etc. generate document files (e.g.,. Doc,. PDF files, etc.).

The scanning service in the mobile phone system scans the media files in each directory of the mobile phone and then stores the media files in the media storage database of the mobile phone. For example, if the mobile phone system is an Android (Android) system, the scanning service may be a MediaScanner service. The MediaScanner service can scan media files in various directories in the mobile phone and store the information of the directories, file names, file sizes and the like of the media files in a media storage database.

And part of APP in the mobile phone can call the media file in the media storage database and show the media file to the user.

For example, a gallery APP is used to present picture files and/or video files. The mobile phone can display the gallery interface 101 shown in fig. 1 in response to an operation of a user triggering to enter the gallery APP. A plurality of pictures are displayed in the gallery interface 101.

For another example, the file management APP is used to display document files, picture files, audio and video files, and the like. The mobile phone may display a file management interface 201 shown in fig. 2 in response to an operation of the user triggering entry into the file management APP. The file management interface 201 displays a picture file, a video file, and the like. The mobile phone can also receive the selection operation of the user on the options of "document", "video", "picture", "music", etc. in the file management interface 201, and the mobile phone can display the corresponding type of media files in response to the selection operation.

It should be noted that the APP which can call the media file in the media storage database does not save the media file itself, but queries the media storage database and presents the corresponding media file. For example, the gallery APP queries the picture file and/or the video file and then displays the picture file and/or the video file.

After the media files are presented to the user, the user may then view the media files and may manipulate the corresponding media files. For example, pictures in a gallery may be viewed and edited. Thereby enabling viewing and use of the media files.

However, in the conventional technology, after the user uses some APPs that do not store pictures according to the standard rule, the cell phone may display the gallery interface 301 shown in fig. 3 in response to the user triggering the operation of entering the gallery APP. The gallery interface 301 includes multiple legal pictures and an illegal picture 302. The illegal picture 302 is a picture showing the word "under the review of suspected violation system". For the illegal picture, the picture cannot be checked, and bad influence can be caused. For example, the user may not know the cause of the illegal picture, or the user may have a bad evaluation of the mobile phone or APP in the mobile phone.

It should be understood that fig. 3 described above is an illustration for a picture file. For other types of media files, for example, document files or audio-visual files, etc. If the APP does not store the files according to the standard rules, the user cannot normally use the files. For example, a file cannot be opened or a messy code is left after opening. Or, some adverse effects may be caused.

Based on this, the embodiment of the present application provides a file processing method, which is applied to electronic devices such as a mobile phone, and the electronic devices can provide viewing and using functions of media files of types such as pictures, audios and videos, and/or documents. The electronic equipment can update the media storage database according to the identified illegal media files, so that the updated database does not include the illegal media files. The electronic device then uses the updated media storage database to provide file services to the user. For example, the media file is provided to a gallery application for presentation. Therefore, illegal media files can be shielded, legal media files can be provided for users, and service performance is improved. It should be noted that an illegal media file may also be referred to as an illegal media file.

For example, the electronic device in the embodiment of the present application may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) \ Virtual Reality (VR) device, and other devices that can provide viewing and using functions of media files of the type of pictures, audios, and/or documents, and the embodiment of the present application does not particularly limit the specific form of the device.

The methods in the following embodiments may be implemented in the electronic device 400 having the above-described hardware structure. The method of the embodiment of the present application will be described below by taking the electronic device 400 as a mobile phone as an example.

In the scheme of the application, the mobile phone firstly identifies illegal media files in the mobile phone. Specifically, the process of identifying an illegal media file includes the following two steps:

step 1, the mobile phone collects a directory of media files stored in the mobile phone.

In a mobile phone, media files generated by different APPs may be stored in the same or different directories. The mobile phone collects the directories stored with the media files so as to analyze illegal media files in a targeted manner in the following process.

For example, the directories storing picture files in the mobile phone include "picture/screenshot", "picture/111", and "picture/222", and then need to be analyzed with respect to the above directories.

And 2, analyzing the media files in the catalog by the mobile phone to identify illegal media files.

The mobile phone can identify illegal media files in the mobile phone periodically or irregularly. For example, a mobile phone may begin to identify illegal media files after it is turned off (e.g., charged). As another example, a cell phone may begin to identify illegal media files at a fixed time each morning. Therefore, illegal media files can be identified when the power consumption of the mobile phone is low.

In some embodiments, the handset may analyze the file content of the media files to identify illegitimate media files. Specifically, for the second media file, if the file content of the second media file includes the preset content, the mobile phone identifies that the second media file is an illegal media file. The second media file is any one of the media files included in the mobile phone. For example, for a picture file, whether a first preset character is included in the picture is identified, for example, the first preset character is a "suspected violation" character. And if the preset characters are included, identifying the picture as an illegal picture. For another example, for a document file, it may be identified whether the content of the document is scrambled, and if so, it is identified as an illegal document. Therefore, illegal media files can be identified only according to the file contents of the media files without excessively referring to other data of the media files.

In other embodiments, the handset may analyze the record that generated the media file for the second media file to identify an illegal media file. And if the record for generating the second media file does not comprise the second event, identifying the second media file as an illegal media file. Wherein the second event is used for indicating that the user allows the storage of the media file. For example, for a picture file, the second event may be an event that a user clicks the download control, and if the record for generating the picture file does not include an event identifier of the event that the user clicks the download control, the picture is identified as an illegal picture. For example, during the process of browsing the application interface (or the web page) by the user, the automatically downloaded picture file may be regarded as an illegal picture. Thus, the media file generated without permission of the user can be accurately identified as an illegal media file.

In order to simplify the complex operation of identifying illegal media files, a preset Artificial Intelligence (AI) analysis model may be used to complete the identification. The preset AI analysis model has the function of identifying illegal media files. And the preset AI analysis model can be obtained by training the media file and the illegal labeling result or the legal labeling result corresponding to the media file. The media file is used as training input data, and an illegal labeling result or a legal labeling result is used as training output data. After training is completed, any media file is input into a preset AI analysis model, and the preset AI analysis model can output a legal or illegal recognition result.

After the illegal media file is identified and obtained through the steps 1 and 2, the mobile phone can filter the illegal media file when updating the media storage database, and only the legal media file is updated into the media database. Thus, illegal media files can be shielded.

In the embodiment of the application, three processing modes are provided for processing illegal media files, and the media database is updated according to the processing result so as to filter the illegal media files. These three processing modes will be specifically described below.

In a mode 1, an embodiment of the present application provides a method for processing a file, which is applied to a mobile phone. The mobile phone can provide viewing and using functions of media files of types such as pictures, audios, videos and/or documents. In this embodiment, the mobile phone stores the illegal media files and the directories where the illegal media files are located in the blacklist, and filters the illegal media files according to the blacklist during updating. In this embodiment, the directory in which the illegal media file is located may also be referred to as a first directory.

Specifically, as shown in FIG. 5, the method includes S501-S503.

S501, the mobile phone adds the information of the illegal media files and the information of the directory where the illegal media files are located to a preset blacklist in an associated mode, and meanwhile the illegal media files are reserved in the directory.

Illustratively, the media file is a picture file. The directory for storing the picture file includes a directory 604 in the mobile phone storage interface 601 shown in (a) in fig. 6, i.e., a directory "picture/screenshot"; a directory 605, i.e., a directory "picture/111", in the handset storage interface 602 shown in fig. 6 (b); and a directory 606 in the handset storage interface 603 shown in fig. 6 (c), i.e., a directory "picture/222". Among them, the identified illegal pictures include a picture 607 under the catalog "picture/111", i.e., 655.Jpg, and a picture 608, i.e., 666.Jpg. And picture 609 under the directory "picture/222", i.e., 699.Jpg. After the illegal picture is identified, the illegal picture and the directory thereof can be added in a preset blacklist in an associated manner, so that the preset blacklist comprising the following contents can be obtained: picture/111/655. Jpg, picture/111/666. Jpg, picture/222/699. Jpg.

It should be noted that in the above example, only picture files are shown under each directory, but in practice, multiple types of media files may be included under one directory. For example, a directory includes both picture files and video files.

The illegal information of the media file refers to information that can uniquely identify the media file. Illustratively, the information of the illegal media file may be a name of the illegal media file, such as the name 666.Jpg, or may be a file content of the illegal media file, or may be a hash (hash) value of the name or the content, or the like. The embodiment of the present application is not particularly limited to this.

Similarly, the information of the directory refers to information that can uniquely identify the directory. For example, the information of the directory may be a name of the directory, such as name picture/111, or a hash (hash) value of the name. The embodiment of the present application is not particularly limited to this.

The mobile phone can store the information of the illegal media files and the information of the directories in which the illegal media files are located in the preset blacklist in a correlated manner according to the preset format, so that the illegal media files in each directory can be searched in the subsequent scanning process. In the embodiment of the present application, the form of the information related to the illegal media file and the information of the directory where the illegal media file is located is not specifically limited.

In some embodiments, the illegal media file and the directory where the illegal media file is located are associated in a format of "information of the directory where the illegal media file is located/information of the illegal media file". For example, if the name "655.Jpg" of the illegal picture is used as the subdirectory of the name "picture/111" of the directory in which the illegal picture is located, the following related information "picture/111/655. Jpg" can be obtained.

In other embodiments, the illegal media file and the directory thereof are associated by storing the illegal media file and the directory thereof as a piece of data. For example, "{ }" is used to divide two pieces of data, illegal picture "655.Jpg" and the directory "picture/111" where it is located may be stored as one piece of data { picture/111, 655.Jpg } in the following format.

In the following embodiments, the scheme of the present application will be mainly described in the format of "information of a directory where an illegal media file is located/information of an illegal media file".

In this embodiment, the content of the file in the directory where the illegal media file is located is not changed by the mobile phone. For example, after the picture file 699.Jpg shown in (c) of fig. 6 and the directory "picture/222" where the picture file is located are added to the preset blacklist, the picture file 699.Jpg still remains under the directory "picture/222".

S502, the mobile phone responds to a first event of updating the media storage database, filters out illegal media files in all directories for storing the media files according to a preset blacklist, and only scans the rest media files.

Which may be a system service in the handset to scan for media files. For example, mediaScanner service in Android system.

The first event is used for triggering the mobile phone to update the media storage database. The first event may be an update event that is automatically triggered by the handset. For example, the first event is an event that the mobile phone is turned on, restarted or turned off in a flight mode, or the first event is an event that arrives at a preset periodic interval. Alternatively, the first event may be an event of sending a scan broadcast to a system service of the handset after the blacklist update is completed. That is, after the update of the blacklist is completed, the update of the media storage database is triggered, so that the illegal media files can be cleaned in time.

For the second directory, before the mobile phone scans the second directory, the mobile phone firstly queries whether a preset blacklist includes information of the second directory and information of a media file associated with the information of the second directory. And if the information of the second directory and the information of the media files related to the information of the second directory are not included, the fact that illegal media files do not exist in the second directory is indicated. In this case, the handset may scan all media files under the second directory. The second directory is any directory for storing media files in the mobile phone, and may be any of the first directories, for example.

Illustratively, the content included in the preset blacklist is: picture/111/655. Jpg, picture/111/666. Jpg, picture/222/699. Jpg. The directory to be currently scanned is a directory "picture/screen shot" shown in (a) in fig. 6. The preset blacklist does not include any picture file under the directory "picture/screenshot", that is, does not include the picture files 611.Jpg, 622.Jpg and 633.Jpg. At the time of scanning, all media files under the directory "pictures/screenshots" may be scanned.

Otherwise, if the information of the second directory and the information of the media file associated with the information of the second directory are included, it is indicated that an illegal media file exists in the directory. In this case, the mobile phone may filter out the illegal media files indicated by the information of the associated media file, and only scan the media files other than the illegal media files indicated by the information of the associated media file. Thereby realizing that only legal media files in the directory are scanned.

Illustratively, the content included in the preset blacklist is: picture/111/655. Jpg, picture/111/666. Jpg, picture/222/699. Jpg. The directory to be currently scanned is a directory "picture/111" shown in (b) of fig. 6. The preset blacklists "picture/111/655. Jpg" and "picture/111/666. Jpg" are subdirectories of the directory "picture/111". And, the illegal media file corresponding to the sub-directory "picture/111/655. Jpg" is picture 655.Jpg, and the illegal media file corresponding to the sub-directory "picture/111/666. Jpg" is picture 666.Jpg. Accordingly, when scanning the directory "picture/111", picture 655.Jpg and picture 666.Jpg are filtered out, and only the remaining legal pictures 644.Jpg and 677.Jpg are scanned.

That is to say, in this embodiment, the mobile phone scans a first media file in the mobile phone in response to the first event, where the first media file does not include a media file corresponding to a directory recorded by the preset blacklist. For example, for a directory that is not listed in the preset blacklist, the first media file is all media files under the directory. For the directory recorded in the preset blacklist, the first media file is a media file under the directory except an illegal media file indicated by the information of the media file associated with the directory.

S503, the mobile phone updates the media storage database according to the scanning result.

Wherein updating the media storage database comprises deleting missing or valid media files in the newly added media storage database and/or deleting invalid media files in the media storage database. The process of updating the media storage database will be described below for these two aspects, respectively.

In a first aspect, legitimate media files are newly added to a media storage database.

Illustratively, the previous update of the media storage database is at 9:00, this time the media storage database is updated at 12, 00, if 1 legal media file is generated between 9. The handset needs to add the newly generated legitimate media file to the media storage database.

That is to say, the media files scanned by the mobile phone are all legal media files, and if at least one of the legal media files is not included in the media storage database, it indicates that the legal media files in the media storage database are missing. For example, a newly generated legitimate media file is missing.

Based on the method, the mobile phone can match the scanned legal media files with the existing media files in the media storage database, and newly add the media files which are scanned by the mobile phone and are not included in the media storage database into the media storage database. Therefore, the newly generated legal media files can be timely updated to the media storage database, and the loss of the legal media files is avoided.

Exemplary, scanned legal pictures are as follows:

{

picture/screenshot, 611.jpg,1.03mb;

pictures/screenshots, 622.jpg,1.5mb;

pictures/screenshots, 633.jpg,219.92kb;

picture/111, 644.Jpg,1.03mb;

picture/111, 677.Jpg,1.03mb;

picture/222, 688.Jpg,1.03MB

}；

The data for the picture file in the media storage database is as follows:

{

pictures/screenshots, 622.jpg,1.5mb;

pictures/screenshots, 633.jpg,219.92kb;

pictures/111, 655.Jpg,1.5mb;

picture/111, 677.Jpg,1.03mb;

picture/222, 688.Jpg,1.03MB

}。

Matching the scanned legitimate media file with a picture file in the media storage database can determine that the media storage database lacks data for pictures 611.Jpg and 644. Jpg. Therefore, the mobile phone needs to add the relevant data of the pictures 611.Jpg and 644.Jpg to the media storage database. The data of the picture file in the newly added media storage database is as follows:

{

picture/screenshot, 611.jpg,1.03mb;

pictures/screenshots, 622.jpg,1.5mb;

pictures/screenshots, 633.jpg,219.92kb;

picture/111, 644.Jpg,1.03mb;

pictures/111, 655.Jpg,1.5mb;

picture/111, 677.Jpg,1.03mb;

picture/222, 688.Jpg,1.03mb;

}。

in a second aspect, an illegitimate media file in a media storage database is deleted.

Illustratively, as shown in fig. 7, the previous update of the preset blacklist is performed at 9:00, if 1 illegal picture is generated between 9. After a first event is triggered by a restart of the handset at 10. If the next time the preset blacklist is updated is at 12, it is obvious that the illegal picture generated between 9. So that illegal pictures may exist in the media storage database. And when the preset blacklist is updated at 12. That is, the illegal picture is not included in the scanning result, but the illegal picture is already present in the media storage database.

That is, all the media files scanned by the mobile phone according to the preset blacklist are regarded as all legal media files in the mobile phone, and if the media storage database also includes media files other than the legal media files scanned this time, it indicates that illegal media files exist in the media storage database. For example, there are illegal pictures generated between 9.

Based on this, the mobile phone can match the scanned legal media files with the existing media files in the media storage database, and delete the media files which are not scanned by the mobile phone and are included in the media storage database from the media storage database. Therefore, the illegal media files existing in the media storage database can be deleted in time, and the trouble of the illegal media files to users is avoided.

Still taking the scan results and the data stored in the media storage database as examples in the first aspect as before, matching the scanned legitimate media file with the picture media file in the media storage database may determine that there is an extra picture 655.Jpg data in the media storage database compared to the scanned legitimate media file. It can be determined that the data for this picture 655.Jpg is data for an illegal picture that the handset needs to delete from the media storage database. The data of the picture file in the newly added media storage database is as follows:

{

pictures/screenshots, 622.jpg,1.5mb;

pictures/screenshots, 633.jpg,219.92kb;

picture/111, 677.Jpg,1.03mb;

picture/222, 688.Jpg,1.03MB

}。

In some embodiments, the two above aspects may be combined, namely: newly adding newly generated legal media files to the media storage database in time, and deleting illegal media files existing in the media storage database in time.

Still taking the scanning result and the data stored in the media storage database as examples in the first aspect, after addition and deletion, the data of the picture file in the media storage database is as follows:

{

picture/screenshot, 611.jpg,1.03mb;

pictures/screenshots, 622.jpg,1.5mb;

pictures/screenshots, 633.jpg,219.92kb;

picture/111, 644.Jpg,1.03mb;

picture/111, 677.Jpg,1.03mb;

picture/222, 688.Jpg,1.03mb;

}。

in summary, by using the method of the embodiment of the present application, the illegal media file is added to the preset blacklist, and meanwhile, the data in the directory where the illegal media file is located is not changed. And then, when the media storage database is scanned and updated, illegal media files under each directory are filtered according to a preset blacklist, and only legal media files are scanned. And updating the media storage database according to the scanning result, realizing adding the newly generated legal media files into the media storage database, and deleting the illegal media files existing in the media storage database. Therefore, the media storage database can be updated on the premise of not changing the media files under each directory, namely, not changing the user data.

For the convenience of understanding the foregoing mode 1, the whole process of the mode 1 will be described below with reference to fig. 8 by taking a picture media file as an example.

And step A, after picture catalogue information of a user is collected and an illegal picture is identified by using an AI analysis model, updating a preset blacklist according to the illegal picture and a catalogue in which the illegal picture is located. For example, if the information of the illegal picture and the directory where the illegal picture is located is not included in the preset blacklist, the illegal picture and the directory where the illegal picture is located are added to the preset blacklist in an associated manner. Otherwise, no addition is made.

And step B, sending a scanning broadcast after the preset blacklist is updated, or triggering the scanning of the picture file in the mobile phone after the mobile phone is started.

And C, judging whether a preset blacklist exists or not. And D, if the preset blacklist does not exist, indicating that an illegal picture does not exist, and executing the step D. And E, if the preset blacklist exists, indicating that the illegal picture exists, and executing the step E.

And D, scanning all pictures under each directory, thereby scanning all legal pictures.

And E, filtering out the pictures in each directory, wherein the pictures are included in the preset blacklist, and scanning the rest pictures. Specifically, for any directory, if the preset blacklist includes the directory and an illegal picture under the directory, the illegal picture under the directory recorded in the preset blacklist is filtered, and other pictures under the directory are scanned. For any directory, if the preset blacklist does not include the directory and the illegal picture under the directory, the directory does not have the illegal picture, and all picture files under the directory can be scanned. Thereby scanning all legal pictures.

And F, updating the database, adding the missing legal pictures in the media storage database into the media storage database, and deleting the illegal pictures in the media storage database. Thereby obtaining a media storage database which does not include illegal pictures and simultaneously includes the latest legal pictures.

Mode 2, an embodiment of the present application provides a method for processing a file, which is applied to a mobile phone. The mobile phone can provide viewing and using functions of media files of types such as pictures, audios, videos and/or documents. In this embodiment, the mobile phone moves the illegal media file from the directory where the illegal media file is located to the preset directory, stores the preset directory in the blacklist, and filters out the illegal media file according to the blacklist during updating. In this embodiment, the directory in which the illegal media file is located may also be referred to as a third directory, and the preset directory may also be referred to as a first directory. Specifically, as shown in fig. 9, the method includes S901-S903.

S901, the mobile phone moves the illegal media files from the directories to the preset directories, and deletes the illegal media files from the directories. And the information of the preset directory is stored in a preset blacklist.

Still taking fig. 6 (a), fig. 6 (b), and fig. 6 (c) as examples, the identified illegal pictures include pictures 655.Jpg and 666.Jpg under the catalog "picture/111". And includes picture 699.Jpg under the catalog "picture/222". The mobile phone can remove 655.Jpg and 666.Jpg from the directory "picture/111" to obtain the mobile phone storage interface 1002 shown in (b) in fig. 10, and the mobile phone storage interface 1002 no longer includes illegal pictures under the directory "picture/111", but only includes legal pictures. E.g. only picture 644.Jpg and picture 677.Jpg.

Likewise, the cell phone can remove the picture 699.Jpg from the directory "picture/222", resulting in the cell phone storage interface 1003 shown in (c) in fig. 10, where the cell phone storage interface 1003 no longer includes illegal pictures under the directory "picture/222", but only legal pictures. E.g. only picture 688.Jpg.

However, the directory "picture/screenshot" originally including no illegal picture is not changed, and like the picture files in the directory "picture/screenshot" included in the mobile phone storage interface 1001 shown in (a) in fig. 10, the picture files in the directory "picture/screenshot" included in the mobile phone storage interface 601 shown in (a) in fig. 6 all include pictures 611.Jpg, 622.Jpg, and 633.Jpg.

Also, the handset can move the removed illegal pictures, such as pictures 655.Jpg, 666.Jpg and 699.Jpg, to the directory 1102, i.e. directory "picture/333", in the handset storage interface 1101 shown in fig. 11. That is, the preset directory is a directory "picture/333".

The preset directory may be a newly created directory or may be a historically created directory. For example, if the present application is currently used for the first time, a new default directory needs to be created. If the scheme is used before, the preset directory created by the history can be directly used. Alternatively, the preset directory may be a directory that is originally in the mobile phone and is not used for storing the media file. For example, the preset directory may be an empty directory that does not store any content.

After an illegal media file is removed from the directory in which it is located, the illegal media file is no longer included in the directory. Meanwhile, the illegal media file is moved to a preset directory, and the illegal media file can be reserved. So that the user data is not deleted.

The information of the preset directory is stored in the preset blacklist, and the directory including the illegal media file can be searched from the preset blacklist subsequently. Similarly, the information of the preset directory also refers to information that uniquely identifies the preset directory.

S902, the mobile phone filters out the preset directories according to the preset blacklist in response to a first event for updating the media storage database, and scans the media files in the remaining directories.

In this embodiment, the remaining directory may also be referred to as a fourth directory. That is, the fourth directory is a directory other than directories recorded in the preset blacklist. The fourth directory is any directory for storing media files in the mobile phone, and for example, may be any directory in the third directory.

For the first event, reference may be made to the related description in the foregoing S502, and details are not described here.

The mobile phone can inquire a preset directory for storing illegal media files from a preset blacklist, and only scan the media files under the directories except the preset directory without scanning the media files under the preset directory during scanning. So that illegal media files are not scanned.

For example, the mobile phone queries the directory "picture/333" from the preset blacklist, that is, the directory "picture/333" is an illegal directory, and only directories other than the directory "picture/333" are scanned during scanning. For example, the catalog "picture/screen shot" shown in (a) in fig. 10, the catalog "picture/111" shown in (b) in fig. 10, and the catalog "picture/222" shown in (c) in fig. 10 are scanned. Illegal media files in the 3 directories are removed, so that legal media files are scanned.

That is to say, in this embodiment, the mobile phone scans a first media file in the mobile phone in response to the first event, where the first media file does not include a media file corresponding to a directory recorded by the preset blacklist. I.e. not scanning media files under the preset directory.

And S903, updating the media storage database by the mobile phone according to the scanning result.

Similarly, updating the media storage database may include adding legitimate media files missing from the media storage database to the media storage database and/or deleting illegitimate media files from the media storage database. That is, the first aspect and the second aspect similar to S503 are also included, and for specific implementation of the first aspect and the second aspect, reference may be made to the relevant description in S503, and details will not be described here.

In summary, by using the method of the embodiment of the present application, the illegal media file is removed from the directory where the illegal media file is located, so that the corresponding directory does not include the illegal media file any more. And the illegal media files are moved to the preset directory, so that the illegal media files are all concentrated to the preset directory, and meanwhile, the illegal media files can be still kept in the mobile phone.

Then, when the media storage database is scanned and updated, the media files under the directories except the preset directory are scanned, and the illegal media files can be filtered. And updating the media storage database according to the scanning result, realizing adding the newly generated legal media files into the media storage database, and deleting the illegal media files existing in the media storage database. Therefore, illegal media files in each directory do not need to be removed one by one during scanning. Therefore, the calculation amount during scanning updating can be simplified, and the updating efficiency is improved.

In order to facilitate understanding of the foregoing mode 2, the complete process of mode 2 is described below with reference to fig. 12 and by taking a picture file as an example.

Step a, after picture catalog information of a user is collected and an illegal picture is obtained through identification of an AI analysis model, the illegal picture is removed from a catalog where the illegal picture is located, and the illegal picture is moved to a centralized preset catalog.

And b, updating the preset blacklist according to the preset directory. For example, if the preset directory is not included in the preset blacklist, the preset directory is added to the preset blacklist. Otherwise, no addition is made.

And c, sending scanning broadcast after the preset blacklist is updated, or triggering the scanning of the picture file in the mobile phone after the mobile phone is started.

And d, judging whether a preset blacklist exists or not. And e, if the preset blacklist does not exist, indicating that an illegal picture does not exist, and executing the step e. And f, if the preset blacklist exists, indicating that an illegal picture exists, and executing the step f.

And e, scanning all pictures in the catalog so as to scan all legal pictures.

And f, filtering out the preset directories recorded in the preset blacklist, and scanning the pictures under the other directories. Specifically, during scanning, pictures in other directories, except the preset directory recorded in the preset blacklist, are scanned. Thereby scanning all legal pictures.

And g, updating the database, adding the missing legal pictures in the media storage database into the media storage database, and deleting the illegal pictures in the media storage database. Thereby obtaining a media storage database which does not include illegal pictures and simultaneously includes the latest legal pictures.

Mode 3, an embodiment of the present application provides a method for processing a file, which is applied to a mobile phone. The mobile phone can provide viewing and using functions of media files of types such as pictures, audios, videos and/or documents. In this embodiment, the mobile phone moves the illegal media file from the directory where the illegal media file is located to the preset directory, where the preset directory is provided with a preset flag, and the preset flag is used to instruct the mobile phone not to scan the preset directory when the media storage database is updated. In this embodiment, the directory in which the illegal media file is located may also be referred to as a first directory. In a specific implementation, the preset directory is a subdirectory of the first directory (i.e., the preset subdirectory hereinafter). Specifically, as shown in FIG. 13, the method includes S1301-S1303.

And S1301, the mobile phone moves the illegal media files from the directory where the illegal media files are located to the subdirectory under the directory, the preset subdirectory is provided with a preset mark, and the preset mark is used for indicating that the preset subdirectory is not scanned. And deleting the illegal media file from the directory where the illegal media file is located.

Still taking (b) in fig. 6 as an example, the identified illegal pictures include pictures 655.Jpg and 666.Jpg under the catalog "picture/111". The cell phone can remove pictures 655.Jpg and 666.Jpg from the directory "picture/111" and move to a preset subdirectory under the directory "picture/111". For example, the content included under the directory "picture/111" after removal may include, as shown in a mobile phone storage interface 1401 shown in (a) in fig. 14, pictures 644.Jpg and 677.Jpg under a directory 1402, that is, the directory "picture/111", and a folder corresponding to a preset sub-directory, that is, a folder 444. After moving the illegal picture to the preset sub-directory, the contents included in the preset sub-directory may include 655.Jpg and 666.Jpg illegal pictures under the preset sub-directory 1404, i.e., the directory "picture/111/444", as shown in the handset storage interface 1403 shown in (b) of fig. 14.

Wherein, if the scheme is used for the first time, the preset subdirectory can be a newly-built directory. Alternatively, if the scheme has been used before, the preset subdirectory may be a historically created directory, which may be used directly this time.

In this embodiment, the illegal media file is moved to a preset subdirectory under the directory where the illegal media file is located. The preset subdirectory has a preset mark so that the scanning of the preset subdirectory is skipped according to the preset mark in the subsequent scanning.

Wherein the preset mark may be a second preset character included in the directory. For example, the preset mark is the character "444" in the directory "picture/111/444" shown in (b) in fig. 14. That is, when the mobile phone detects that the directory includes the preset characters, it indicates that the directory is the preset sub-directory, and the media files therein are illegal media files.

Alternatively, the preset flag may be a file in a preset format in a preset subdirectory. For example, the preset flag may be a "nomedia" file under the directory "pictures/111/444" (which may also be referred to as a file that masks a media software scan). That is, when the mobile phone detects that the directory includes the preset file, it indicates that the directory is the preset sub-directory, and the media file therein is an illegal media file.

S1302, the mobile phone responds to the first event, filters out the preset sub-directories according to the non-scanning marks, and scans all the remaining directories.

For the first event, reference may be made to the related description in the foregoing S502, which is not described herein again.

For any directory, if the directory includes preset sub-directories, when scanning the media files in the directory, the scanning of the preset sub-directories is skipped, and only the media files except the preset sub-directories are scanned. So that illegal media files stored in the preset subdirectory can be filtered. If the directory does not include the preset subdirectory, all the media files in the directory can be scanned when the media files in the directory are scanned. Therefore, all legal media files can be scanned, and illegal media files can be filtered.

Illustratively, the preset flag is a file including ". Nomedia". When the mobile phone detects that the subdirectory 'picture/111/444' under the directory 'picture/111' includes a 'biomedia' file, the mobile phone indicates that the subdirectory 'picture/111/444' is a preset subdirectory. When scanning the directory "picture/111" shown in (a) in fig. 14, only pictures 644.Jpg and 677.Jpg thereof are scanned. Without scanning the media files in the subdirectory "pictures/111/444".

That is to say, the mobile phone responds to the first event, and scans the first media file in the mobile phone, and the directory where the first media file is located has no preset mark.

And S1303, the mobile phone updates the media storage database according to the scanning result.

Similarly, updating the media storage database may include adding legitimate media files missing from the media storage database to the media storage database and/or deleting illegitimate media files from the media storage database. That is, the first aspect and the second aspect similar to those in S504 are also included, and for specific implementation of the first aspect and the second aspect, reference may be made to relevant descriptions in S504, and details will not be described here.

In summary, by using the method of the embodiment of the present application, illegal media files under each directory can be collected into preset subdirectories under the directory. And the preset subdirectory is provided with a preset mark, so that the preset subdirectory can be conveniently identified as the subdirectory for storing illegal media files during scanning.

Then, when the media storage database is scanned and updated, the preset sub-directories are identified according to the preset marks, and only the media files under the directories except the preset sub-directories are scanned. So that illegal media files can be filtered out. And updating the media storage database according to the scanning result, realizing adding the newly generated legal media files into the media storage database, and deleting the illegal media files existing in the media storage database.

For the convenience of understanding the foregoing mode 3, the whole process of the mode 3 will be described below with reference to fig. 15 by taking a picture file as an example.

Step a), after picture directory information of a user is collected and an illegal picture is identified by an AI analysis model, the illegal picture is removed from the current directory to a preset subdirectory under the current directory, and a nomedia file is created under the preset subdirectory. The nomedia file is used to indicate that the preset subdirectory is not scanned.

And b), sending scanning broadcast after the mobile phone is removed to a preset subdirectory, or triggering the scanning of the picture files in the mobile phone after the mobile phone is started.

And c), only scanning the media files under the directory without the nomedia files during scanning, so that only legal pictures can be scanned.

Step d), updating the database, adding the missing legal pictures in the media storage database into the media storage database, and deleting the illegal pictures in the media storage database. Thereby obtaining a media storage database which does not include illegal pictures and simultaneously includes the latest legal pictures.

After the media files in the media storage database are updated in any one of the manners, the mobile phone responds to the user to trigger the operation of starting the APP (such as the gallery APP) for displaying the media files, and then the media files of corresponding types can be displayed to the user according to the media file data in the updated media storage database. Thus, illegal media files can be shielded, and only legal media files can be displayed to users. The following takes the presentation of the picture file as an example, and describes a process of presenting a corresponding type of media file to the user according to the updated media file data in the media storage database with reference to fig. 16.

As shown in fig. 16, after triggering the starting of the gallery APP, the gallery APP may send a picture data query request to the media storage database. And after receiving the picture data query request, the media storage database filters file data of the picture file, and then returns the file data of the picture file to the APP of the library. Since the data of the legal media files are stored in the media database, the corresponding file data which is returned to the gallery APP and is also the legal pictures is returned. And displaying the legal picture to the user according to the file data of the legal picture by the picture library APP. Therefore, illegal pictures can be shielded, and only legal pictures are displayed to users.
