Problems solved by technology

The disadvantages are: the hardware parameters of the mobile phone cannot be obtained; the program information (program name, version number, etc.) 90,000, the annual upgrade fee is about 20,000-30,000, and the input and output are not directly proportional
The disadvantages are: poor support for domestic phones; unable to obtain the hardware parameters of the mobile phone; does not support obtaining the program information (program name, version number, etc.) Address record information; expensive
The disadvantages are: the hardware parameters of the mobile phone cannot be obtained; the program information of the mobile phone system itself and the program installed by the user (program name, version number, etc.)

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] The evidence collection system of the present invention includes a software data collection subsystem and a hardware data collection subsystem. The software data forensics subsystem mainly extracts the data generated by the application software in the mobile phone, including: address book, call records, MMS, SMS, Internet access records and usage records of several major instant messaging software. The hardware data forensics subsystem mainly extracts the data of the mobile phone chip, and copies the data of the mobile phone chip bit by bit.

[0038] The data forensics system based on Android (Android) of the present invention can extract the software data and hardware data of the mobile phone, fully cover all the data of the Android mobile phone, and can g...

Abstract

The invention provides a data evidence obtaining system based on the Android. The data evidence obtaining system based on the Android comprises a virtual interface unit, a software data evidence obtaining subsystem and a hardware data evidence obtaining subsystem. The virtual interface unit is connected with a Linux kernel of the Android of a terminal, a virtual layer is formed between an application framework layer and the Linux kernel of the Android, and the Android using the terminal takes the virtual layer as an application of the Android of the terminal. The software data evidence obtaining subsystem is used for acquiring software data of the terminal. The hardware data evidence obtaining subsystem is used for acquiring chip hardware data of the terminal.

Description

technical field [0001] The invention belongs to the technical field of data forensics, in particular to an Android-based data forensics system. Background technique [0002] With the popularization of smart phone applications, various types of cases involving mobile terminals emerge in an endless stream. The processing and analysis of mobile terminal evidence is becoming more and more urgent in the process of forensic identification, evidence collection and investigation. Simultaneously, Android (Android) system is a mobile phone operating system that rises rapidly in recent years. Its user coverage has already ranked first in smartphones with a 27% share in 2011. The demand for forensic system of Android system is imminent. [0003] In the existing technology, most of the existing products can only obtain part of the information such as the address book and SMS records in the smart phone, and cannot obtain the hardware parameter information of the mobile phone, the mobil...
