Location Permission Control for Application API Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems lack an effective method to determine whether application programs are allowed to use location-based services, particularly in environments where specific operating systems do not provide direct APIs for such determinations.
Innovation Solution
A control method that involves calling a predetermined API to acquire information from the operating system, determining successful acquisition by the application program, and executing processes based on the outcome to allow or deny location-based services accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If application programs call predetermined APIs to acquire location information, then the ability to use location-based services is improved, but system security and control over unauthorized access deteriorate
Solution Approach 1:
The system performs preliminary determination of whether an application program is allowed to use location-based services before the program actually calls the API. The control unit checks the permission status in advance, and only if permission is granted does it allow the API call to proceed. This prevents unauthorized access before it can occur, while still allowing legitimate applications full access to location services.
2Ease of operation
If the system allows all application programs to call location APIs, then ease of operation is improved, but measurement precision of permission status deteriorates
Solution Approach 1:
The control unit acts as an intermediary between application programs and the location information system. Instead of allowing direct access, the control unit receives API calls from applications, checks their permission status against the permission management unit's records, and either grants or blocks access accordingly. This intermediary mechanism ensures precise determination of permission status while maintaining ease of operation for authorized applications.
3Reliability
If the system implements strict permission checking, then system security is improved, but device complexity increases
Solution Approach 1:
The permission management unit maintains a self-updating record of which application programs are allowed to use location-based services. When the user grants or revokes permission through the settings interface, the system automatically updates its internal permission database without requiring complex external verification. The control unit simply queries this existing record, making the security mechanism reliable but relatively simple to implement.

AI summary
A control method comprises: not executing a predetermined process for causing a user to perform an operation for allowing the predetermined application program to use a location-based service based on successful acquisition of the predetermined information by the predetermined application program, and executing the predetermined process based on failure to acquire the predetermined information by the predetermined application program.
