Embodiment 1

[0030] The present invention mainly provides a safe and reliable anti-flash method, which solves the problems of poor safety and low reliability of existing anti-flash products. The core idea of ​​the present invention is to use the feature that the kernel driver cannot be modified and replaced by the flasher, and add a detection mechanism to the kernel driver. Once the system area is found to be modified, the device cannot work normally, thereby achieving the purpose of preventing flashing.

[0031] Since the flasher cannot modify and replace the kernel driver, the most intuitive way is to add a detection mechanism to the kernel driver. The specific implementation steps are as follows:

[0032] Step S11, extracting the feature code of the system partition, such as using CRC;

[0033] Step S12, encrypting the CRC code and storing it in the kernel;

[0034] Step S13, adding a verification program in the kernel, which is used to scan the system partition and calculate the CRC a...

Abstract

The invention discloses an anti-flash method. The anti-flash method comprises the following steps that a feature code is extracted on a compiled system partition; the feature code is encoded and stored; a detection program is added in equipment software; a kernel driver is modified to be used for guaranteeing the legality of the detection program; after starting up, a program check system area is detected to be in communication with a kernel, if check fails or communication is abnormal, flashing is considered to be conducted, and normal using is stopped. The anti-flash method solves the reliability and safety problem of anti-flash, and the effectiveness of an anti-flash technology is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of computers, and relates to a method of anti-flashing, in particular to an anti-flashing method applicable to Android devices. Background technique [0002] Android (Chinese name Android) devices include Android mobile phones, tablets, TVs, etc., hereinafter referred to as "Android smartphones". Make some key functions invalid, etc.) to prevent flashing. The greatest feature of the present invention is to utilize the kernel driver to ensure accurate discovery of whether the Android system software has been modified. [0003] Android is currently the smart device operating system with the largest market share. It is an open source platform based on Linux led by Google and provides a complete set of Android smart phone solutions. At present, major domestic manufacturers have developed a large number of Android smart phones, but a common problem encountered is that after the production of mobile phones, inte...
