OS-Side Notification for Guardian Service Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current guardian service systems that use smartphones to monitor children's positions face privacy concerns due to the need to share real-time location data with developers, leading to potential data leakage and increased security burdens.
Innovation Solution
A guardian service provision system that utilizes an OS-side positional information acquisition unit to determine if a child has left a set monitoring area, notifying the application only when the child departs, thus minimizing data transmission and reducing the need for high-security measures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the current position of the guarding target is measured and recorded by an application of a smartphone, then the guardian service can monitor the child's location, but privacy information including real position and usage information may be leaked to the developer/operator of the application
Solution Approach 1:
The patent extracts the positional information measurement function from the application layer and places it in the OS layer. The OS's positional information acquisition unit independently measures the smartphone's current position and compares it with the monitoring area, extracting only the necessary notification signal while leaving the detailed positional data in the OS layer where it is protected from application access.
Solution Approach 2:
The OS acts as an intermediary between the positional information source and the application. The OS side notification unit serves as a mediator that receives positional information internally, processes it against the monitoring area, and outputs only a simple notification signal to the application, preventing direct exposure of detailed location data.
2Object-affected harmful factors
If high level security measures are implemented to prevent privacy information leakage, then information security is improved, but necessary costs increase and the burden on the developer/operator side increases
Solution Approach 1:
The patent removes the need for complex security measures in the application by extracting the sensitive positional information handling to the OS layer. The application only receives a simple notification signal, eliminating the need for encryption, secure storage, and other complex security infrastructure that would be required if the application directly handled detailed location data.
Solution Approach 2:
The OS provides the security service for positional information protection automatically through its built-in positional information acquisition unit and notification mechanism. The system self-manages the sensitive data within the OS layer without requiring external security measures or complex application-side security implementations.
3Reliability
If continuous monitoring of the child's position is performed, then the guardian service provides comprehensive protection, but more privacy information is transmitted and stored
Solution Approach 1:
The patent implements partial monitoring by only detecting when the child leaves the monitoring area rather than continuously tracking and transmitting all positional information. The OS side notification unit performs the minimal necessary action of comparing current position with the monitoring area boundary and generating a notification only when needed, providing adequate protection without excessive data collection.

AI summary
[Problem] To protect privacy when monitoring a child going to school or preparatory school, by restricting information saved on the application side. [Solution] A system for providing a guardian service for monitoring a management target Ch under supervision by means of his/her smartphone 3, said system comprising: an application execution unit 312 for executing an application on an OS of the smartphone 3; a position information acquisition unit 39 for measuring the current position of the smartphone 3 as a function of the OS; a monitoring area setting unit 245a for setting a monitoring area A1 for the position information acquisition unit 39; an OS side notification unit 331c for, when the current position of the smartphone 3 is out of the monitoring area A1, issuing a notification to that effect to an application side notification acquisition unit 312a as the function of the OS; and the notification acquisition unit 312a serving as a function of the application for acquiring notifications from the OS side notification unit 331c.
