Abstract

In response to mobile terminal threats, this work is innovative, and gives practical solutions and prototype systems. The work first analyzes in detail the entire process of the generation, transmission and use of user-sensitive data within the Android system. In order to achieve resource sharing and data transmission between different applications and processes, the Android system provides a mechanism for inter-process communication based on Binder. Sensitive data is transmitted through Binder as a channel in the system. But sensitive data is carried out in the form of clear text during Binder transmission, which allows malware to easily intercept and tamper with sensitive data based on Binder communication, such as SMS content and GPS location information. In response to this problem, based on the above research, this work innovatively proposes and implements an adaptive transparent encryption protection scheme for sensitive data in the Android system from generation to use throughout the life cycle, effectively preventing sensitive data from being. The threat of theft and tampering by malicious third parties guarantees the privacy and integrity of user sensitive data during the internal transmission of the system. In addition, the system provides users with a simple and flexible operating experience, allowing users to independently protect specific types of sensitive data in specified applications, enhancing the ease of use and practicality of the system.
