Map Data Anti-Counterfeiting via Expired Content Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current map data anti-counterfeiting methods are ineffective in concealing and protecting map data from misappropriation, as companies often merge and use other companies' data without proper verification.
Innovation Solution
The method involves acquiring expired map data, adding anti-counterfeiting content such as dithering processing on road shape data or homophone replacement in name data, and creating an anti-counterfeiting map based on basic and expired data, which increases the concealment and verification effectiveness of map data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If companies use proprietary map data collected by themselves, then the map data accuracy and reliability are improved, but the complexity of data collection and verification processes increases
Solution Approach 1:
The patent applies preliminary action by embedding anti-counterfeiting content into map data before it is used or shared. This pre-processing step ensures that the data carries inherent verification markers that can detect misappropriation later, without requiring complex verification processes during data collection or usage phases.
Solution Approach 2:
The patent introduces anti-counterfeiting content as an intermediary element between the proprietary map data and the final map product. This intermediary layer carries verification information that bridges the gap between data collection and verification, simplifying the overall process while maintaining reliability.
2Adaptability or versatility
If companies merge and use other companies' map data, then the map product completeness and versatility are improved, but the risk of data misappropriation and counterfeiting increases
Solution Approach 1:
The patent applies preliminary anti-action by pre-embedding anti-counterfeiting content into map data before it is merged or shared between companies. This preventive measure creates verification markers that can detect and prevent misappropriation, allowing companies to safely merge data while protecting against counterfeiting risks.
Solution Approach 2:
The patent implements feedback mechanisms through anti-counterfeiting content that provides verification information about the origin and integrity of map data. This feedback loop allows companies to verify the authenticity of merged data and detect misappropriation attempts, enabling safe data sharing while maintaining security.
3Reliability
If anti-counterfeiting content is added to map data, then the concealment and verification effectiveness are improved, but the data processing complexity and time consumption increase
Solution Approach 1:
The patent applies local quality by adding anti-counterfeiting content only to specific critical portions of the map data rather than processing the entire dataset uniformly. This selective approach maintains verification effectiveness while reducing processing time and computational overhead.
Solution Approach 2:
The patent uses partial action by implementing anti-counterfeiting measures only where most critical for verification, rather than applying comprehensive protection across all data elements. This partial approach achieves sufficient anti-counterfeiting effectiveness with minimal time and resource investment.
Data Source
AI summary
An expired map data based anti-counterfeiting method, apparatus, storage medium and device. The method includes: acquiring currently expired map data; adding anti-counterfeiting content to the currently expired map data and storing the currently expired map data containing the anti-counterfeiting content; and creating and storing a current anti-counterfeiting map based on basic map data and the currently expired map data containing the anti-counterfeiting content. Using the anti-counterfeiting content added to the currently expired map data as the anti-counterfeiting map data, compared with using false data for anti-counterfeiting in the map data, increases the concealment of the anti-counterfeiting data in the anti-counterfeiting map and improves the anti-counterfeiting effect of the anti-counterfeiting map.
