Map Enrichment via External Data Brokerage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital geographical maps lack the ability to securely integrate and display user-specific, sensitive information without compromising data privacy, as this information is often shared with the map service provider or visible to all users.
Innovation Solution
A method and system that store additional data separately from map data and metadata, correlating it to geographical coordinates, and provide access via an authentication service, ensuring end-to-end encryption and transparency to the user, while maintaining data security and privacy by using a broker system and trusted authority for user credentials and encryption keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional data is stored outside map data and metadata, then data security and privacy are improved, but device complexity increases
Solution Approach 1:
The system divides data storage into separate components: map data remains with the map service provider, while additional user-specific data is stored externally in a separate storage unit. This segmentation isolates sensitive data from the map provider's infrastructure, enhancing security while allowing independent management of different data types.
Solution Approach 2:
A broker system is introduced as an intermediary between the user and external data storage. The broker manages correlation of additional data to map coordinates, handles authentication requests, and facilitates secure access without requiring direct integration between the map provider and external services, thus simplifying the architecture despite the added complexity of external storage.
2Adaptability or versatility
If additional data is correlated to geographical coordinates, then functionality and data integration are improved, but device complexity increases
Solution Approach 1:
The correlation unit serves multiple functions: it correlates additional data to geographical coordinates, manages authentication, and enables access to various types of external data services. This multi-functional design consolidates complexity into a single component rather than requiring separate systems for each function.
Solution Approach 2:
Instead of storing complete copies of map data externally, the system stores only the necessary additional data elements and correlates them to specific coordinates. This selective copying approach reduces the data volume and processing complexity while maintaining the ability to integrate multiple data sources.
3Reliability
If authentication service is implemented for accessing additional data, then data privacy is improved, but ease of operation decreases
Solution Approach 1:
User credentials and encryption keys are established in advance through a trusted authority before the user needs to access additional data. This preliminary setup eliminates the need for repeated authentication during data access, as the system can use pre-established credentials to automatically authenticate and decrypt data, thus maintaining security while simplifying user interaction.
Data Source
AI summary
A method for enriching map functions of a digital geographical map is provided. Additional data are stored in a storage unit outside map data of the digital geographical map and direct related map metadata. Elements of the additional data are correlated to coordinates of the digital geographical map. Further, access is provided to the additional data via an authentication service while navigating the geographical map.
