Problems solved by technology
[0004] In the existing technology, there are many data recovery and mobile phone forensics related to smart phones, but there are few technologies related to data recovery and mobile phone forensics of non-smart phones. For example, for non-smart phones equipped with Spreadtrum CPU, the CPU is an early product , and the internal data structure is relatively complicated, therefore, the data recovery and mobile phone forensics of this type of mobile phone have not been involved in the prior art; Deleting call records and text messages after text messages has brought various difficulties to the investigation and evidence collection of the case. Therefore, there is an urgent need for a method to analyze the font library of Spreadtrum CPU mobile phones and restore the deleted information

Embodiment Construction
[0059] The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.
[0060] Such as figure 1 Shown, a kind of method of parsing Spreadtrum CPU mobile phone font and recovering deleted information comprises the following steps:
[0061] S1: Connect the mobile phone to the computer and extract the font of the mobile phone: the call records, address book and short message of the Spreadtrum CPU mobile phone are all stored in its font, and the capacity of the font includes but is not limited to 8M, 16M and 32M bytes. In this embodiment, The font capacity is 16M bytes.
[0062] S2: Dividing the character library into multiple blocks: In this embodiment, the 16M byte character library is divided by 0x20000 bytes per block, which can be divided into 127 blocks.
[0063] S3: parse and restore the information in each block: including such as figure 2 The following steps are shown:
[0064] S301: After jumping back 8 bytes fr...

The invention discloses a method for parsing a Spreadtrum CPU mobile phone character library and recovering deleted information. The method is characterized by comprising the following steps that 1, a mobile phone is connected to a computer, and a character library of the mobile phone is extracted; 2, the character library is divided into multiple blocks; 3, information in all blocks is parsed and recovered; 4, whether parsing and recovering of the character library are completed or not is judged, if yes, the process is finished, otherwise, the step 3 is executed. Accordingly, call logs, address books and short messages of the Spreadtrum CPU mobile phone can be parsed and recovered, the technical vacancy that in the prior art the Spreadtrum CPU mobile phone character library cannot be parsed, and the deleted information cannot be recovered is filled up, the problem that data recovering and evidence obtaining cannot be conducted on the Spreadtrum CPU mobile phone is solved, and blind spot that this kind of electronic evidence cannot be obtained is avoided.
Description
technical field [0001] The invention belongs to the field of data recovery and electronic forensics, relates to mobile phone data recovery and mobile phone forensics, and in particular relates to a method for analyzing Spreadtrum CPU mobile phone fonts and recovering deleted information. 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. However, it is not uncommon to use mobile phones to commit crimes such as fraud, defamation and forgery. Mobile phone data recovery and mobile phone forensics are an effective means to combat such crimes. [0003] Conceptually speaking, mobile phone forensics is to collect, preserve and analyze relevant electronic evidence from mobile phone SIM cards, mobile phone internal and external memory cards, and mobile network operator databases, an...
