Desensitization encryption method for information sent by chat tool of mobile equipment

Abstract

A desensitization encryption method for information sent by a chat tool of a mobile device comprises the following steps: step 1, defining a Service class in an Android, and enabling the class to inherit a self-assistance class; 2, further declaring the service class in the step 1 in a configuration file automatically generated by the Android project; 3, realizing an auxiliary service event processing method and an auxiliary service terminal method in the subclass service; 4, setting auxiliary functions in the mobile phone to find the auxiliary class realized in the step 3, and then opening the auxiliary class; 5, according to the strategy of the secret-related field issued from the server, starting an examination mechanism according to the monitored text content, and judging whether the currently monitored content has violation behaviors or not; according to the method, the content input by the soft keyboard can be acquired and monitored, and then the sensitive vocabulary designed inthe monitored content is forcibly encrypted and desensitized.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for desensitizing and encrypting information sent by a chat tool of a mobile device. Background technique [0002] At present, more and more efforts are being invested in the protection of sensitive information leaks and the tracing of leakers in departments or institutions with high confidentiality. For example, instant messaging software is not allowed in relevant departments or sending some related information to third-party forums Confidential or sensitive text, and will also monitor the content of the sent text to implement relevant review mechanisms and track secret-related personnel. [0003] In the existing solutions, it is generally necessary to root the mobile phone and then use the xposed framework to forcibly modify the sent content, or not allow the use of certain modules of the application. [0004] To a large extent, any desired data can be obtained thr...

Problems solved by technology

[0004] To a large extent, any desired data can be obtained through the root method, and the improvement of permissions after rooting can realize many functions that can only be realized at the system level, such as: forced modification of third-party data or disabling some functions of third-party applications, etc., but The solution must be that the Android device has obtained root privileges, the physical characteristics of the hardware itself and the standards of major hardware manufacturers are different, and the rooted mobile phone has great security risks, and it is easy to be invaded by Trojan horses and viruses.
