Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing geolocation systems for mobile devices suffer from high latency and vulnerability to location spoofing, which can degrade user experience and lead to financial losses, particularly in applications requiring real-time location verification.

Innovation Solution

Implement a system that caches geolocation tokens with expiration dates, continuously refreshes them before expiration, and uses spoof-checking mechanisms to ensure low-latency and trusted location information delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system continuously requests fresh geolocation tokens from the server for each location verification, then the location information is always up-to-date and trusted, but the system latency increases and user experience degrades

Engineering Contradiction:

Improvelocation verification accuracyVSAvoidlocation retrieval latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by continuously refreshing geolocation tokens in the background before they are needed, maintaining a cache of valid tokens. This allows the application to retrieve location information immediately from the cache when needed, eliminating latency while ensuring the cached tokens are refreshed beforehand to maintain accuracy and trustworthiness

Inventive Principle:

Principle #10Preliminary action

2Loss of time

If the system uses GPS coordinates directly from the device, then the location information is immediately available with zero latency, but the system becomes vulnerable to location spoofing attacks

Engineering Contradiction:

Improvelocation retrieval timeVSAvoidlocation trustworthiness

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The system introduces an intermediary mechanism - a server-issued geolocation token - that mediates between the device's GPS coordinates and the application's location verification needs. The token acts as a trusted credential that the server has verified, allowing the application to trust location information without directly querying GPS, thus maintaining both speed and reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the system implements comprehensive spoof-checking mechanisms to ensure location accuracy, then location verification reliability improves, but the system complexity and processing time increase

Engineering Contradiction:

Improvelocation verification accuracyVSAvoidsystem architecture complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system extracts the complex spoof-checking functionality from the application and relocates it to the server. The server performs comprehensive verification of GPS coordinates, device identifiers, and network information to issue authenticated geolocation tokens. This extraction reduces application complexity while maintaining high verification accuracy through server-side security mechanisms

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

Systems and methods for low-latency geolocation checks include retrieving updated geolocation tokens at regular intervals and caching the geolocation tokens in local memory on a mobile device. The geolocation tokens are retrieved from the cache in response to location check requests from other processes running on the mobile device.
