Problems solved by technology

[0006] Most of the existing mobile terminal data recovery technologies only recover the data storage files of the mobile terminal, find out the data segments marked as deleted and restore them, and cannot recover those storage units that have been marked as unused in the memory chip. The data
Therefore, the existing mobile terminal data is restored based on storage files such as databases, and the restored data is incomplete.
A small number of mobile terminal data recovery software can directly restore the memory blocks of mobile terminals, but they are limited to mobile terminals with simple coding rules and fixed data storage locations in the early days, mainly traditional non-intelligent mobile terminals, and intelligent mobile terminals widely used now there is nothing you can do

Embodiment Construction

[0026] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] One of the core ideas of the present invention is to provide a method and device for restoring data of a mobile terminal based on an image file. Among them, the above-mentioned method for recovering mobile terminal data is characterized by the effective encoding rules of the mobile terminal, by extracting the complete image of the storage medium, querying the effective data in the image that matches the encoding rules in the full-text index, extracting the effective data for reorganization, decoding and Fragmentation analysis to recover various said data.

[0028] refer to figure 1 , showing a first method embodiment of the present invention for recovering mobile terminal data, including:

[0029] Step 1, loading the mobi...

Abstract

The invention provides a method and a device for recovering data of a mobile terminal. The method comprises the steps of loading a mobile terminal image file and a mobile terminal image source identifying base; matching coding features of the mobile terminal image file by utilizing the mobile terminal image source identifying base, and identifying the source mobile terminal of the mobile terminal image file; loading a data rule base of the source mobile terminal; invoking rules in the data rule base of the mobile terminal, and performing coding rule matching for the mobile terminal image file so as to obtain effective data or fragmented data; and decoding the effective data or the fragmented data according to the rules in the data rule base of the mobile terminal, and recovering the data of the mobile terminal. By the method, all uncovered data on the mobile terminal can be recovered completely, and partially covered fragmented data on the mobile terminal also can be recovered, and the method has the advantages of high recovery success rate, fast searching speed, complete recovered data, and the like.

Description

technical field [0001] The invention relates to the technical field of data recovery, in particular to a method and device for recovering data of a mobile terminal. Background technique [0002] With the continuous development of electronic technology and computer technology, the hardware performance and software functions of mobile terminals such as mobile phones have been rapidly improved, and they have become powerful assistants in people's lives. A large number of contact numbers and other information materials can be conveniently stored on the mobile phone. Once the mobile phone is stolen or lost, information is deleted by mistake, files are damaged, the system crashes, the hardware of the mobile terminal is damaged, etc., the loss of the above information will bring a lot of inconvenience to mobile phone users. [0003] Mobile terminal data recovery, especially mobile phone data recovery, which is closely related to people's lives, is based on data loss at the level o...
