System, configuration method and method for preventing eavesdropping of intelligent terminal voice

Abstract

The invention discloses a system, a configuration method and an encryption method for preventing voice eavesdropping of an intelligent terminal. In the system configuration method of intelligent terminal voice anti-eavesdropping, the intelligent terminal voice anti-eavesdropping system at least includes, kernel layer and system layer, and PCM audio encryption layer; PCM audio encryption layer is configured between kernel layer and system layer, makes kernel layer The audio data is transmitted to the system layer through the PCM audio encryption layer; the PCM audio encryption layer includes a hardware PCM audio configuration module, a hidden PCM audio configuration module and a default PCM audio configuration module. The present invention sets the PCM audio encryption layer between the kernel layer and the system layer, thereby effectively separating the interactive voice and audio, so as to ensure that the normal use of the non-eavesdropping application and the system application can also effectively ensure that the voice and audio during the interaction process The security of the mobile terminal system has greatly improved the anti-eavesdropping level and the effectiveness of the system without adding hardware devices.

Description

technical field [0001] The invention belongs to the technical field of mobile terminal security and application, and relates to a system, a configuration method and a method for preventing eavesdropping on voice of an intelligent terminal. Background technique [0002] During the use of mobile smart terminals, more and more applications and occasions require users to interact through voice. However, in the process of users interacting through voice, their own information and private content will be involved. In order to steal this part of the content, some applications usually implant the user's smart mobile terminal in various ways to eavesdrop and embezzle the internal content, thus seriously threatening and affecting the information security of the user's mobile terminal. In the existing related technologies, There are mainly the following schemes for mobile terminals to protect user voice privacy: The first scheme: layered management, strictly restricting the illegal ac...

AI Technical Summary

Problems solved by technology

It can be seen that most of the existing anti-eavesdropping methods for mobile terminals are realized through simple encryption, system verification or hardware isolation.
