Position Information Access Control via Segmented Decryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current positioning systems face challenges in providing accurate and timely location determination, especially in urban areas and indoors, due to signal interference and lack of control over access to position information, leading to potential delays in emergency services and bandwidth inefficiencies.
Innovation Solution
A system that implements a two-stage decryption process for position information using air-link access certificates and authorized service-level certificates to control access to position information, ensuring only authorized applications receive accurate and secure location data, while minimizing system performance impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If position information is transmitted without access control, then all applications can access position data, but network bandwidth is wasted and service quality deteriorates
Solution Approach 1:
The patent segments position information into multiple encrypted streams with different security levels and access rights. Each application receives only the position data it is authorized to access, based on its security credentials. This segmentation prevents unauthorized applications from consuming network bandwidth while allowing legitimate applications to access necessary position information efficiently.
Solution Approach 2:
The patent introduces a security intermediary component that manages access to position information. This intermediary verifies application credentials, decrypts position data according to access rights, and distributes encrypted position streams to authorized applications. The intermediary acts as a mediator that controls bandwidth allocation and prevents unauthorized access, thereby reducing network waste while maintaining service quality.
2Reliability
If position information is encrypted with multiple security levels, then access control is improved, but system complexity increases
Solution Approach 1:
The patent divides the encryption system into modular segments, each handling a specific security level or access right. Position information is segmented into multiple encrypted streams with different decryption keys and security credentials. This modular segmentation makes the complex encryption system more manageable and easier to implement while maintaining high security standards.
Solution Approach 2:
The patent applies encryption selectively rather than uniformly to all position information. Different levels of encryption are applied based on the sensitivity and importance of specific position data elements. This partial action approach reduces overall system complexity by avoiding full encryption of all data while still providing robust security where needed.
3Adaptability or versatility
If all applications receive position information, then service coverage is maximized, but network bandwidth is burdened
Solution Approach 1:
The patent applies different quality levels of position information to different applications based on their authorization and service requirements. Each application receives position data with the appropriate level of detail and accuracy for its specific function, rather than all applications receiving identical high-quality data. This local quality approach reduces total bandwidth consumption while maintaining service coverage for all authorized applications.
Solution Approach 2:
The patent provides position information selectively to applications based on their needs and authorization levels. Not all applications receive the same amount or quality of position data - each receives only what is necessary for its function. This partial action principle reduces overall bandwidth usage while maintaining adequate service coverage for all legitimate applications.

AI summary
Controlling access to position information at a receiver, or at another device external to the receiver. Various considerations, including a requested service type, a user type, a device type, a software application type, a payment, and/or other characteristics associated with a particular software application or distributor of that software application, may be used to control access to position information.
