Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0024] like figure 1 As shown, a method for reorganizing data for Symbian system includes the following steps:

[0025] S1: Physically mirror the data of the Symbian system mobile phone;

[0026] S2: Determine whether there is a data area in the image; start scanning XSR2 from the head of the image, and its characteristic is "0X58535232". If this feature is found, it means that there is a data area in the image, and execute S3, otherwise end.

[0027] S3: analyze the structure of the data area, and sort the blocks in the data area;

[0028] S4: Analyze the data structure in each block and sort the data in the block;

[0029] S5: reorganize and extract the data in the reordered block, and recover the normal data.

[0030] The detailed steps of S3 are as follows:

[0031] S301: Continu...

Abstract

The invention discloses a data recombination method for a Symbia system. The data recombination method comprises the following steps of: S1, performing physical mirroring of data of a mobile phone having the Symbia system; S2, judging whether a data area exists in a mirror image or not, starting to scan XSR2 from the head part of the mirror image, if so, showing that the data area exists in the mirror image, executing the S3, and otherwise, ending; S3, analyzing the structure of the data area, and sorting blocks in the data area; S4, analyzing a data structure in each block, and sorting data in the block; and S5, recombining and extracting the resorted data in the block, and recovering normal data. The data recombination method disclosed by the invention has the benefits that: whether data exists in the data area of the Symbia system or not can be judged; data for recombining the Symbia system is completed; the recombined data cannot be corrupted; the recombination success rate is high; polices are assisted to recover mobile phone data; cracking of a criminal case can be assisted; and loss due to data loss can be reduced.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for reorganizing data for Symbian systems. Background technique [0002] With the continuous improvement and expansion of the service level and service types provided by mobile communication technology, mobile phones have increasingly become an indispensable contact tool in people's work and life. Not uncommon. Mobile phone forensics is an effective means of combating such crimes. Conceptually speaking, mobile phone forensics is to collect, preserve and analyze relevant electronic evidence from the internal / external memory card of the mobile phone SIM card and the mobile network operator database, and finally obtain legally effective evidence that can be accepted by the court. the process of. At present, there are generally three types of criminal acts involving mobile phones: one is that mobile phones are used as communication tools during the implementa...
