Memory-chip data acquiring device for AX-flash mobile phones

Abstract

The invention discloses a memory-chip data acquiring device for AX-flash mobile phones. The memory-chip data acquiring device is characterized by comprising an eMMC (embedded multi- media card) chip clamping holder, an eMCP (embedded master control program) chip clamping holder, a memory-controller chip and a level selection switch, wherein the eMMC chip clamping holder and the eMCP chip clamping holder respectively establish signal connection with the memory-controller chip through two independent data buses, the memory-controller chip is provided with a USB (universal serial bus) main machine interface, and the level selection switch is connected with the eMMC chip clamping holder and the eMCP chip clamping holder. The memory-chip data acquiring device disclosed by the invention has the benefits that when the memory-chip data acquiring device disclosed by the invention is used, a memory chip in a mobile phone needs to be separated from a main board, and therefore, the use of the memory chip is not influenced by the damages of a display screen, a cell and a communication interface of the mobile phone; the device disclosed by the invention is provided with the eMMC chip clamping holder and the eMCP chip clamping holder in two different interface manners, and therefore, the device can satisfy the reading requirements for more than 99% of memory chips on the current mobile phone market; the device disclosed by the invention is provided with two independent data buses for supporting the simultaneous data analysis of memory chips, of two different specifications, of the mobile phone, so that the data reading efficiency is high.

Description

technical field [0001] The invention relates to a data acquisition device, in particular to a mobile phone storage chip data acquisition device. Background technique [0002] Initially, mobile phone forensics was only about recovering deleted data as much as possible on the basis of extracting original data. With the rapid development of mobile phone technology itself and the high popularity of smart phones, mobile phone forensics technology is also continuously subdivided. According to the different capabilities of forensics tools and different from traditional computer forensics technology, mobile phone forensics can be divided into the following three levels: [0003] First level: manual extraction. [0004] That is, directly view the relevant data on the mobile phone, and use a camera and other replica equipment to record the evidence. [0005] Provided the phone is not damaged. [0006] Second level: logical extraction. [0007] That is, an effective connection is e...

AI Technical Summary

Problems solved by technology

[0013] (1) When the display, battery or communication interface of the mobile phone is damaged, the forensic equipment cannot be connected to the mobile phone;

[0014] (2) The mobile phone model supported by the forensic device must be used to use the forensic device, which is too restrictive
