Single QR Code for Multi-Provider Data Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing QR code systems require multiple codes for different data segments, making it cumbersome for users to manage and access various information sets, such as travel itineraries, during trips, without a unified and secure solution.
Innovation Solution
A method and system that encodes multiple data sets into a single QR code using cryptographic keys, allowing only authorized entities to access specific data segments, leveraging Auto Secure Code generators and blockchain technology for secure storage and dynamic updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple QR codes are used for different data segments, then data security and access control are improved, but user convenience and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple encrypted data segments into a single QR code structure. Each data segment (e.g., hotel reservation, flight itinerary, car rental) is encrypted separately with its own cryptographic key, but all segments are merged into one unified QR code that users carry and present, eliminating the need to manage multiple separate codes.
Solution Approach 2:
The patent segments the QR code data into multiple encrypted portions, each protected by a different cryptographic key. When the QR code is scanned, the system segments the decryption process by applying the appropriate key to each data segment, allowing selective access to specific information while maintaining overall code integrity.
2Reliability
If multiple QR codes are used for different providers, then data confidentiality is improved, but device complexity and management burden increase
Solution Approach 1:
The patent creates a universal QR code structure that can accommodate multiple data segments from different providers (hotels, airlines, car rental companies) within a single code. This multi-functional design allows one QR code to serve multiple purposes and access multiple data sources, reducing the need for separate provider-specific codes.
Solution Approach 2:
The patent introduces an intermediary decryption system that manages the complexity of multiple cryptographic keys. When a provider needs to access its data, the intermediary system automatically applies the correct cryptographic key to decrypt the relevant segment, shielding users from the complexity of key management while maintaining strong confidentiality.
3Reliability
If cryptographic keys are used for each data segment, then access control and security are improved, but processing time and system complexity increase
Solution Approach 1:
The patent applies preliminary encryption to each data segment before the QR code is generated and distributed to users. The cryptographic keys are pre-configured and associated with their respective data segments during the code creation process, so that when decryption is needed, the system can quickly retrieve and apply the appropriate pre-prepared key without delay.

AI summary
A data processing system is used to encode and aggregate data sets from different sources and embed the conglomerated data in a single QR code. The encoding uses identifications and encryption keys to maintain a provider-level segmentation of the aggregated data. When scanning the QR code, the decoding of data sets is also done in a provider-specific manner, thereby keeping other data parts of the QR code confidential. Thus, the housekeeping burden on a user is mitigated as only a single QR code for multiple service providers is necessary, while data security is maintained.
