Referring to fig. 2, fig. 2 is a schematic flowchart of a data recovery method provided in an embodiment of the present application, and is applied to a mobile terminal, where the mobile terminal runs a third-party application, as shown in fig. 2, the data recovery method includes:
s201, a mobile terminal acquires target data in a preset storage space, wherein the target data is data illegally requested to be deleted in the process of executing preset operation by a third-party application program, the preset storage space is a special storage space for storing the data, and the target data comprises a plurality of files.
The third-party application program may be, for example, an instant messaging application, a game application, or the like, and the third-party application program may be installed by a user, or may be preinstalled by a developer before the mobile terminal leaves a factory, which is not limited herein.
The target data may be a document, a picture, audio, and the like, and is not limited herein.
The preset operation may include, but is not limited to, an update operation, an uninstall operation, a delete operation, and the like, and is not limited herein.
S202, the mobile terminal screens out at least one group of files with similarity greater than preset similarity from the target data, and each group of files comprises at least two files.
The similarity can be compared through an algorithm, and the preset similarity is set by a manufacturer when the factory leaves, and is not limited uniquely here.
S203, the mobile terminal determines at least one file which needs to be preferentially restored in each group of files.
S204, the mobile terminal recovers the at least one file in each group of data in a first time interval and recovers files except the at least one group of files in the target data in a second time interval.
The first time period and the second time period may include, but are not limited to, any time period such as five minutes, ten minutes, or fifteen minutes, and are not limited to these.
It can be seen that, in the embodiment of the present application, the mobile terminal transfers the data that the third-party application illegally requests to delete to the preset storage space, selects multiple groups of files with high similarity by comparing the similarity of the files in the target data, and further determines the files that need to be preferentially restored in each group of files, so that the determined files are preferentially restored in the first time period, and the remaining files are restored in the second time period. Therefore, in the process of restoring the target data transferred to the preset storage space, the number of the files needing to be restored in the first period can be reduced, the probability that the user finds that the files are lost is reduced, the situations that time is consumed and the restoration of other files is delayed due to the fact that too many similar files are restored in a plurality of files are avoided, and the efficiency and the intelligence of the mobile terminal in data restoration are improved.
In one possible example, the plurality of files are a plurality of pictures, and the screening at least one group of files with similarity greater than a preset similarity from the target data includes: the mobile terminal extracts a picture characteristic value of each picture in the plurality of pictures; and screening at least one group of pictures with similarity greater than preset similarity from the multiple pictures according to the picture characteristic value of each picture, wherein each group of pictures comprises at least two pictures.
The picture characteristic value can be obtained by the following two methods: firstly, automatically segmenting an image, dividing an object or color area contained in the image, then extracting image characteristics according to the areas, and establishing an index; another method is to simply divide the image into a plurality of regular sub-blocks uniformly, then extract features for each image sub-block, and build an index, which is not limited herein.
Therefore, in this example, the mobile terminal can quickly select similar pictures from the target data by comparing the picture characteristic values to obtain multiple groups of similar pictures, which is beneficial to the high efficiency and accuracy of data screening when the mobile terminal performs data recovery.
In one possible example, the plurality of files includes a plurality of audio files, and the screening of at least one group of files from the target data, the similarity of which is greater than a preset similarity, includes: the mobile terminal carries out filtering processing on each audio file in the plurality of audio files to obtain a filtering graph corresponding to each audio file; and screening at least one group of filter graphs with similarity greater than preset similarity from a plurality of filter graphs corresponding to the plurality of audio files.
Wherein the similarity can be obtained by comparing the amplitude and the frequency in the filtered image.
Therefore, in this example, the mobile terminal obtains the filter graph by filtering the audio, and similar audio can be quickly selected from the target data by comparing the filter graph to obtain multiple groups of similar audio, which is beneficial to the high efficiency and accuracy of data screening when the mobile terminal performs data recovery.
In one possible example, the determining at least one data in each group of data that needs to be preferentially recovered includes: the mobile terminal determines the file attribute of each file in each group of data, wherein the file attribute comprises file creation time; sorting each group of data according to the file attribute of each file to obtain a file sequence corresponding to each group of files; and determining the first file in each file sequence as a priority recovery file.
The sorting may include, but is not limited to, sorting from front to back or sorting from back to front, and is not limited to this.
For example, when the mobile terminal acquires a preset storage space, the picture A, the picture B, the picture C, the picture D and the picture E are available, the picture characteristic value is identified, and two groups of picture files, namely a group A, are obtained: picture a, picture B, and picture E, group B: and C pictures and D pictures, wherein the creation time of the five pictures is respectively that the picture A is 18 click at 20 months and 20 days in 2018, the picture B is 18 click at 20 months and 20 days in 2018, the picture C is 20 click at 20 months and 20 days in 2018, the picture D is 20 click at 20 days and 20 points 01 at 2018, 5 months and 20 days in 2018, and the picture E is 02 click at 20 days and 18 days in 2018, the first file in the group A is obtained by sequencing from front to back, and the first file in the group B is the picture C, and the picture A and the picture B are preferentially replied.
Therefore, in the example, the mobile terminal accurately determines the priority recovery file by comparing the file attributes of the similar files in each group, so that the situation that other files cannot be normally recovered due to repeated recovery of the similar files is avoided, and the intelligence and the efficiency of recovery of a plurality of files are improved.
In one possible example, the determining at least one data in each group of data that needs to be preferentially recovered includes: the mobile terminal determines the reference parameter of each file in each group of data, wherein the reference parameter comprises the reference times or the reference time; sorting each group of data according to the reference parameter of each file to obtain a file sequence corresponding to each group of files; and determining the first file in each file sequence as a priority recovery file.
Wherein, the reference times and the reference time can be obtained from the historical operation records of the mobile terminal operated by the user.
Therefore, in the example, the mobile terminal obtains the reference times or reference time according to the historical operation records, the files which are preferentially recovered can be determined in a targeted mode, and the intelligence and the efficiency of recovering a plurality of files are improved.
In one possible example, the recovering the at least one data of each set of data within the first time period includes: when detecting a consulting request aiming at data in the target data, the mobile terminal recovers icon data or preview view data of each file in the at least one associated file, wherein the data volume of the icon data or the preview view data is smaller than that of a single file; and in a first period, after a consulting request of icon data or preview view data of any file in the at least one associated file is detected, restoring the any file in real time.
The restoring is virtual restoring, wherein the virtual restoring refers to icon data or preview view data with low data volume in a virtual folder, and the virtual restoring folder is not a real folder and has no actual logical structure. Therefore, the contents displayed in the folder may be actually dispersed in a plurality of real folders, and the virtual folder only plays a role of induction and summarization. The minimum amount of memory reserved for page caching.
Therefore, in this example, the mobile terminal displays the plurality of files deleted by mistake as icons or preview views in the folder of the target application program, and further restores the files in real time through the click operation of the user, so that the situation that the user mistakenly regards the permanent deletion of the files due to the fact that the undeleted files are not displayed in the folder of the target application program is avoided, and the intelligence and the efficiency of file restoration of the mobile terminal are facilitated.
Referring to fig. 3, fig. 3 is a schematic flowchart of a data recovery method provided in an embodiment of the present application, and the data recovery method is applied to a mobile terminal, where the mobile terminal runs a third-party application program, and as shown in the figure, the data recovery method includes:

S302, the mobile terminal extracts the picture characteristic value of each picture in the plurality of pictures.
And S303, the mobile terminal screens out at least one group of pictures with the similarity greater than a preset similarity from the multiple pictures according to the picture characteristic value of each picture.
S304, the mobile terminal determines the file attribute of each file in the at least one group of pictures.
S305, the mobile terminal sequences the at least one group of pictures according to the file attributes of each file to obtain a file sequence corresponding to the at least one group of pictures.
S306, the mobile terminal determines the first file in each file sequence as a priority recovery file.
S307, the mobile terminal restores the at least one file in the at least one group of pictures in a first period of time and restores files except the at least one group of files in the target data in a second period of time.
It can be seen that, in the embodiment of the present application, the mobile terminal transfers the data that the third-party application illegally requests to delete to the preset storage space, selects multiple groups of files with high similarity by comparing the similarity of the files in the target data, and further determines the files that need to be preferentially restored in each group of files, so that the determined files are preferentially restored in the first time period, and the remaining files are restored in the second time period. Therefore, in the process of restoring the target data transferred to the preset storage space, the number of the files needing to be restored in the first period can be reduced, the probability that the user finds that the files are lost is reduced, the situations that time is consumed and the restoration of other files is delayed due to the fact that too many similar files are restored in a plurality of files are avoided, and the efficiency and the intelligence of the mobile terminal in data restoration are improved.
In addition, the mobile terminal can rapidly select similar pictures from the target data by comparing the picture characteristic values to obtain a plurality of groups of similar pictures, thereby being beneficial to the high efficiency and the accuracy of data screening when the mobile terminal carries out data recovery.
