Embodiment 1

[0043] An Android-based personalized environment-aware privacy protection method, including: intercepting mobile application privacy permission requests, environment awareness and privacy decision based on functional semantics; the environment awareness and privacy decision based on functional semantics refer to functions based on the environment Semantic understanding of the scenarios in which users use mobile applications and implement corresponding privacy policies accordingly;

[0044] When the mobile application privacy permission request matches the privacy policy in an environment based on functional semantics, the mobile application is allowed or denied to access user privacy information according to the privacy policy.

Embodiment 2

[0046] As described in embodiment 1, a personalized environment-aware privacy protection method based on Android, the method further includes interactive user privacy requirement setting: when there is no matching privacy policy in an environment based on functional semantics, inform The user's mobile application privacy permission request, if the user allows, the mobile application is allowed to access the user's private information; otherwise, it is not allowed.

Embodiment 3

[0048] According to an Android-based personalized environment-aware privacy protection method described in embodiment 1, the interception of mobile application privacy permission requests is implemented in the following manner:

[0049] Use the Xposed framework hook system API to implement, by writing the Xposed module, hook the relevant functions in the hook system to realize the environment-aware privacy decision logic. Xposed framework is a framework service that can affect the operation of the program without modifying the Android program code. Modules written based on the Xposed framework can adjust the execution logic of some services of the Android system without modifying the Android kernel source code to expand system functions. In order to realize the interception of application privacy requests, the present invention implements environment-aware privacy protection decision logic by writing Xposed modules and hooking APIs related to permission management in the system. ...

Abstract

The invention provides a personalized environmental perception privacy protection method based on Android. According to the method, in order to meet personalized privacy demands which are changed due to the environment of a user, a system needs to percept the service environment and the user habit of mobile application, such as time, position, user interaction conditions, application types, concrete behaviors and the like, conduct deep semantic parsing and user behavior study on the environment in which mobile equipment is located, timely adjust a delegated strategy, and meet the requirements of the user. The invention further provides an automatic and controllable privacy management mode at the same time. The user can express his or her privacy requirements by setting a privacy strategy, delegated strategies are set aiming at specific contexts and privacy requests, and automatic and controllable privacy protection with fine grit is achieved.

Description

Technical field [0001] The invention relates to an Android-based personalized environment perception privacy protection method, and belongs to the technical field of mobile terminals. Background technique [0002] In recent years, mobile smart terminals have developed rapidly. By 2015, the number of mobile smart devices in China will exceed 1.3 billion, of which Android platform users account for about 73%. The number of mobile applications has also grown rapidly. As of the first half of 2016, the number of mobile applications under the Android platform exceeded 2 million, and the number of applications used per capita was 26.7. 58% of users check their phones 11-50 times a day, about 1-2 times an hour. And 20% of users check their phones more than 50 times a day. These mobile applications cover everything from food, clothing, housing and transportation to study and work, from leisure and entertainment to sports and medical treatment, and they have deeply integrated into daily ...
