Mobile Terminal Privacy Protection via Virtual Data Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminal operating systems, being open-source except for iOS, lack effective protection for personal information such as address books and location data, leading to easy theft and resulting in significant inconvenience and loss for users.
Innovation Solution
A method and system that establish and store new content and position manager modules in mobile terminals, writing default data into these modules, and monitoring for requests from applications to read original data, disabling the original modules and displaying default virtual data when such requests are detected, thereby protecting user information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If open-source operating systems are used in mobile terminals, then device complexity and adaptability are improved, but personal information security deteriorates
Solution Approach 1:
The patent introduces a content provider module as an intermediary layer between applications and the address book module. This mediator controls and filters data access, allowing the open-source system to maintain adaptability while enhancing security through regulated information flow. The content provider module acts as a gatekeeper that can grant or deny access based on predefined rules.
Solution Approach 2:
The patent segments the address book module into multiple independent components: the original address book module for storing real data, and a virtual address book module for storing fake data. This segmentation allows different security policies to be applied to different modules, enabling the system to maintain both openness and security.
2Ease of operation
If real personal information is stored in accessible modules, then ease of operation is improved, but information security deteriorates
Solution Approach 1:
The patent creates a virtual copy of the address book module that contains fake data mirroring the structure and format of real data. Applications interact with this virtual copy instead of the real data, maintaining ease of operation while preventing actual information leakage. The virtual module is a functional duplicate that serves the same operational needs without compromising security.
Solution Approach 2:
The content provider module serves as an intermediary that redirects access requests from applications to the appropriate module. It can dynamically switch between providing access to the virtual module (for security) and the original module (when authorized), thus balancing accessibility and security based on operational context.
3Reliability
If virtual data is output to protect real information, then information security is improved, but loss of information occurs
Solution Approach 1:
The patent applies different data quality characteristics to different modules: the virtual address book module contains fake data with local quality properties suitable for protection scenarios, while the original module retains accurate real data. This allows the system to provide accurate information when needed while using protected fake data in other contexts, minimizing overall information loss.

AI summary
The present disclosure provides a method for protecting personal information based on a mobile terminal including establishing and storing a new content provider module for storing application data and a new position manager module for storing geographical position data in the mobile terminal in advance, and writing default new application data and default new geographical position data into the new content provider module and the new position manager module, respectively; monitoring, in real time, whether an original content provider and an original position manager module in the mobile terminal include a request for reading data from transmitted by an application; if yes, disabling the original content provider and the original position manager module, and displaying the default new application data and the default new geographical position data. The present disclosure protect the personal information of a user.
