However, the above data encryption method requires the user to manually specify which files to encrypt, the operation is complicated, and it cannot fully protect the user's private information
The method of permission modification also depends on the user's decision. At present, many applications will apply for permissions larger than the scope of functions. This does not mean that the software has the behavior of stealing privacy, and only three simple modification strategies are provided. theft of privacy

Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] An Android platform message-driven core code integrity detection system of the present invention refers to figure 2 , including adding a detection module for verifying the core code in the Android platform system layer, the detection module is provided with a code reading unit 1, a private key encryption unit 2, a code comparison unit 3, a public key decryption unit 4 and a format conversion unit 5 , the code reading unit 1 reads the source code of the compilation system, obtains the content abstract, and sends it to the private key encryption unit 2 and the code comparison unit 3, and the content abstract is encrypted and transformed by the private key to form a digital signature, and is sent to the public key decryption unit 4 for conversion A new content summary is formed, and the new content summary is converted by the for...

The invention discloses an Android platform message-driven core code integrity detection system, which includes adding a detection module for verifying the core code in the Android platform system layer, the detection module reads the source code of the compiling system to obtain a content abstract, and encrypts and generates the content abstract Digital signature, after the client boot program starts the kernel, decrypt the digital signature to get a new content digest, compare the two content digests before and after, if they are consistent, it is determined that the message-driven core code is complete, if not, it is determined that the message-driven core code is not whole. The invention also discloses a method for detecting the integrity of the Android platform message-driven core code, which improves the security of the Android platform message-driven core code.
Description
technical field [0001] The invention belongs to the technical field of mobile intelligent terminals, and in particular relates to an Android platform message-driven core code integrity detection system and an Android platform message-driven core code integrity detection method. Background technique [0002] With the rapid popularization of Android mobile phones, people's mobile phones carry more and more private data closely related to users, such as received or sent text messages, contact phone numbers and email addresses, bank payment passwords, and data collected through sensors. etc. Android applications are driven by messages. With the hidden dangers of the Android system, when users use applications, if they do not operate properly, their privacy will inevitably be leaked. Taking touch events as an example, when an attacker uses the touch event mechanism to implant malicious code at the system layer, when the user is operating the program, the malicious code can recor...
