Description

Technical Field

[0001] The invention belongs to the field of data backup and restoration and data forensics, and relates to a method for extracting third-party application data of a Samsung mobile phone. Background Art

[0002] Smartphones have become an indispensable tool in daily life and are widely used in online shopping, electronic payment, online social networking, travel navigation, etc. Therefore, by analyzing the data in smartphones, investigators can not only obtain information such as calls, payments, and locations of smartphone users, but can even infer information such as the user's identity, network, economy, and health. Therefore, smartphone evidence collection is becoming increasingly important. In order to extract as complete electronic data as possible, investigators need to use a variety of evidence collection techniques to collect evidence.

[0003] Extraction through adb after the Android is turned on is considered logical extraction. This method is the simplest to operate. As long as the phone is not locked, theoretically, it can be used to extract any application. For the Android system, with the improvement of Android versions, especially after version 6.0, less and less application information can be extracted without root permissions. For high-version Android, logical extraction can no longer fully meet the data backup and restoration and data forensics of Android phones.

[0004] Samsung mobile phone manufacturer has launched a tool "S Switch Assistant" that supports transferring data from other brands of mobile phones to new Samsung Galaxy devices. Samsung "S Switch Assistant" can migrate different types of documents to new Samsung Galaxy devices, including photos, videos, notes, calendar events and even device settings.

[0005] However, in the existing technology, when Samsung's "S Switch Assistant" transfers data from third-party applications, such as WeChat, QQ, etc., due to policy or data security factors, Samsung mobile phone manufacturers do not open up permissions to extract third-party application data, and therefore cannot extract third-party application data.

[0006] Currently, there is no method to extract third-party application data using Samsung's "S Switch Assistant". Summary of the invention

[0007] In view of the shortcomings of the prior art, the present invention proposes a method for extracting third-party application data of Samsung mobile phones, which provides a permission file to Samsung "S Switch Assistant" so that "S Switch Assistant" can extract third-party application data, including the following steps:
