[0009] Step S2, using a visualization application, opening the inventory database of the iTunes backup file and locating the Files database table;

[0010] Step S3, editing the data in the inventory database and synchronously modifying the data file backed up by iTunes;

[0011] Step S4, use iTunes again to restore the edited backup file to the target iOS device to complete the data editing.

[0012] According to the above technical solution, in step S1, the iTunes backup file includes a data file, a list file and a status information file.

[0013] According to the above technical solution, the data file is the data of the file system in the device; the manifest file includes Manifest.db and Manifest.plist; wherein Manifest.db stores the attributes of all data files, and Manifest.plist stores the metadata of the backup;

[0014] The status information files include Status.plist and Info.plist. Among them, Status.plist is used to indicate the status of storage backup;

[0015] Info.plist is used to store backup information.

[0016] According to the above technical solution, in step S2, the manifest database of the iTunes backup file opened by the visualization application is specifically the Manifest.db file.

[0017] According to the above technical solution, in step S3, editing the data in the manifest database is editing the Manifest.db data file, including deleting all data of the application, replacing all data files of the application, and modifying part of the data of the application.

[0018] According to the above technical solution, in step S2, the visualization application uses one of SQLite Expert, SQLiteStudio, and Navicat for SQLite.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] Through the method of the present invention, users can easily edit and modify data in iOS devices, which provides users with greater flexibility to manage device content. Through iTunes backup, users can easily restore to the original state when data editing errors occur, and only need to perform backup and restore again. Therefore, the method of the present invention provides a certain degree of security during the data modification process.

[0030] Embodiment 2

[0031] This embodiment provides a specific implementation method.

[0032] A method to indirectly manage the internal file system of an iOS device by editing iTunes backup. The main technical principles are as follows:

[0033] 1. iOS devices can back up device data through tools such as Finder or iTunes, export iTunes backup files, and restore them to the device when needed.

[0034] 2. iTunes backup files mainly consist of 3 parts:

[0035] 1) Data files: These are a series of files named with SHA-1 hash values ​​and without extensions. If the iOS version is 10 or above, the first two characters of the hash value will be used as the directory for storage. These data files correspond to the data files of the file system in the device (all user data files except the operating system).

[0036] 2) Manifest files: including Manifest.db and Manifest.plist; Manifest.db stores the properties of all data files, such as file size, file timestamp, access permissions, relative path of files in the device file system, etc.; Manifest.plist stores backup metadata, such as device name, device UUID, and backup encryption information.

[0037] 3) Status information files include Status.plist and Info.plist; Status.plist stores the backup status, such as whether it is a full backup or whether the backup is complete. Info.plist stores the backup information, such as the backup time and the APP information installed on the device.

[0038] 3. Through the index of the backup list database Manifest.db, each data file in the backup can be matched one by one with the file in the device file system.

[0039] 4. According to the above steps, you can perform editing operations such as adding, modifying, and deleting the data files and Manifest.db in the backup, and then restore them to the original device through tools such as Finder or iTunes to achieve the purpose of modifying the data files inside the device. These data files may be data files of a certain application, such as photos in the album APP, files transmitted in the instant messaging APP, or configuration files of the iOS system, such as configuration files for language region, user preferences, AppleID, etc.

[0040] The technical problem to be solved by the present invention comprises the following steps:

[0041] Step 1: Use iTunes to perform a full backup of the target iOS device and output the iTunes backup file.

[0042] Step 2, use SQLite visualization application (for example: SQLite Expert), open the backup list database Manifest.db file, and locate the Files database table. The meaning of each field in the Files database table is:

[0043] 1. The fileID field indicates the id of the data item. If the data item is a file, the file name in the backup directory is the fileID. This field is obtained by performing SHA-1 hashing on the domain+"-"+relativePath fields of the data item.

[0044] 2. The Domain and relativePath fields indicate the location of the data file in the iOS device file system, for example:

[0045] 1.HomeDomain:Library / Calendar / Extras.db corresponds to / var / mobile / Library / Calendar / Extras.db

[0046] 2.WirelessDomain:Library / Databases / CellularUsage.db corresponds to / var / wireless / Library / Databases / CellularUsage.db

[0047] a)AppDomain-net.whatsapp.WhatsApp:Documents / SyncHistory.plist corresponds to / var / containers / Bundle / Application / CF24C019-8A47-4244-95FC-3DDBC42D6A96 / WhatsApp.app / Documents / SyncHistory.plist.

[0048] 3. The flags field indicates the type of data item: 1 indicates a file, and 2 indicates a folder.

[0049] 4. The file field stores data in plist binary format, which mainly represents the attributes of the file and its summary information.

[0050] Step 3, edit Manifest.db, data files,

[0051] For example, the following case:

[0052] Case 1: Delete all data of the SMS application. Perform the following operations: Execute the SQL statement:

[0053] DELETEFROMFilesWHEREdomain='HomeDomain'andrelativePathlike'Library / SMS%'

[0054] Close Manifest.db.

[0055] Case 2: To replace all data files of the Contacts app, perform the following operations:

[0056] Execute SQL statements to query the relevant files of the contact application: SELECT * FROM Files WHERE domain = 'HomeDomain' and relativePath like 'Library / AddressBook%'

[0057] Replace the data file:

[0058] Replace the iTunes backup data files with AddressBook.sqlitedb and AddressBookImages.sqlitedb files respectively: 31 / 31bb7ba8914766d4ba40d6dfb6113c8b614be442, cd / cd6702cea29fe89cf280a76794405adb17f9a0ee.

[0059] Update the file field of the data items 31bb7ba8914766d4ba40d6dfb6113c8b614be442 and cd6702cea29fe89cf280a76794405adb17f9a0ee (replace the file) respectively, use the SHA-1 hash summary of the file and replace it with the Digest field of the plist document after encoding it with Base64, update the Size field with the file size, and optionally update the LastModified, LastStatusChange and other fields.

[0060] Use SQLite Expert to view the file field, save the binary file to the local disk, and use plist Editor to open the saved file.

[0061] Edit the content and save: Use SQLite Expert to import the edited plist file; Close Manifest.db.

[0062] Add the setting.json file to the Documents directory of the Health application container.

[0063] Execute the SQL statement to check whether the container directory exists:

[0064] SELECT*FROM Files WHERE domain='AppDomain-com.apple.He alth'.

[0065] Use SQLite Expert to add data items:

[0066] 1. Calculate the SHA-1 hash value "f3fa04d7bca5cd63f012e5b6a346270456657e3a" of "AppDomain-com.apple.Health-Documents / setting.json" as the content of the fileID field.

[0067] 2. Use "AppDomain-com.apple.Health" as the content of the domain field.

[0068] 3. Use "Documents / setting.json" as the content of the relativePath field.

[0069] 4. Use 1 as the content of the flags field.

[0070] 5. Based on the file field of other data items as a template, use the properties, SHA-1 summary, and relative path of the setting.json file to build a file plist document as the content of the file field.

[0071] Copy the setting.json file to the iTunes backup data file: f3 / f3fa04d7bca5cd63f012e5b6a346270456657e3a.

[0072] d. Close Manifest.db.

[0073] Step 4. Use iTunes again to restore the edited backup file to the target iOS device.

[0074] Step 5: After the restoration is completed, the purpose of modifying the data files inside the device is completed.
