Problems solved by technology

[0016] 2. Android 11 has narrowed the storage permissions to a certain extent, but it is only valid for applications with a targetSDK30 or higher. The targetSDK of major domestic applications will still be lower than 30 for a certain period of time.
[0017] 3. The fragmentation of the Android ecosystem is serious, and the stock of Android firmware versions lower than Android 11 is relatively large, and it takes a long time to upgrade to the latest version
[0019] From the above, it can be seen that in the actual user environment of Android 11, partition storage does not improve the situation of user storage space. At the same time, it can be seen that a large number of directories, hidden directories, files and hidden files under the sdcard are used to mark Device information is even used for functions such as ad tracking

Embodiment 1

[0055] The present invention provides a method for preventing advertisement tracking, such as figure 2 shown, including:

[0056] Step 1: Determine whether the target application performs read and write operations in the application-specific directory;

[0057] Step 2: If read and write operations are performed in the application-specific directory, perform IO operations according to the original directory;

[0058] If the read and write operations are not performed in the application-specific directory, the storage redirection operation is performed on the target application, and the IO operation is performed according to the redirected directory.

[0059] Preferably, the original directory refers to the initial generated directory corresponding to the target application.

[0060] In this embodiment, for example, when browsing the APP Taobao page, relevant advertisement files will be automatically loaded to track the user's operations. At this time, it is necessary to preven...

Embodiment 2

[0065] On the basis of Embodiment 1, if the read and write operations are not performed in the application-specific directory, the storage redirection operation is performed on the target application, including:

[0066] Determine whether the first file exists in the non-application-specific directory;

[0067] If it exists, redirect to the application-specific directory of the target application;

[0068] If it does not exist, create a second file and redirect to the corresponding application-specific directory.

[0069] Preferably, the first file and the second file refer to files with the same suffix.

[0070] Preferably, the suffixes of the application-specific directory are the same as the suffixes of the first file and the second file.

[0071] Preferably, the non-application-specific directory is an external storage directory.

[0072] In this embodiment, for example, if the dedicated directory corresponding to the application is 123, then the remaining directories e...

Embodiment 3

[0079] Based on any one of Embodiments 1-2, the storage redirection operation is implemented based on the fuse user space file system.

[0080] The beneficial effect of the above technical solution is: Android 11 uses the fuse user space file system, so that it can be processed in the user space instead of in the kernel file system, with low difficulty, high feasibility, and high stability.

Abstract

The invention provides a method for preventing advertisement tracking. The method comprises the following steps: step 1, determining whether a target application is subjected to read-write operation under an application exclusive directory or not; 2, if read-write operation is carried out under the application exclusive directory, IO operation is carried out according to an original directory; and if the read-write operation is not carried out under the application exclusive directory, carrying out storage redirection operation on the target application, and executing IO operation according to the redirected directory. Through redirection operation, data sharing between applications is effectively blocked, and behaviors such as advertisement tracking are prevented.

Description

technical field [0001] The invention relates to the technical field of advertisement tracking, in particular to a method for preventing advertisement tracking. Background technique [0002] The Android system generally includes external storage, content storage, and partition storage, and partition storage includes application-specific directories, public directories, and other directories. [0003] Among them, external storage: refers to storage / emulated / 0, which is commonly referred to as sdcard. Before Android 10, the application can read and write as long as the storage permission is granted, which is the source of confusion in the sdcard directory, and applications can access each other; [0004] Internal storage: refers to data / data / application package name (for example, data / data / com.android.mms means the internal storage data of SMS App), applications are isolated from each other and cannot access data of other applications; [0005] Partitioned storage: To allow us...
