Cryptographic Data Exchange for Travel Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack efficient and secure methods for matching and exchanging customer records across multiple service providers while preserving customer privacy and controlling the distribution of proprietary information, particularly in the travel industry.
Innovation Solution
A cryptographically enforced data exchange system that includes a communication component, normalization component, cryptographic component, and matching component to tokenize, hash, and securely match customer travel records, allowing exchange between travel providers without disclosing protected data elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If customer travel data is exchanged between multiple travel providers, then service quality and customer experience are improved through better coordination, but customer privacy and confidentiality of proprietary information are compromised
Solution Approach 1:
The patent introduces a data exchange platform that acts as an intermediary between travel providers. This platform enables data sharing and matching while implementing privacy preservation techniques such as tokenization and selective disclosure, allowing providers to coordinate services without directly exposing sensitive customer information to each other
Solution Approach 2:
The patent segments customer data into different types (personal information, travel preferences, booking details) and applies different levels of protection and sharing permissions to each segment. This allows selective sharing of necessary information while protecting sensitive data, enabling service coordination without complete data exposure
2Ease of operation
If travel providers share customer information to improve service coordination, then customer experience is enhanced, but control over distribution of proprietary information is lost
Solution Approach 1:
The patent implements dynamic permission settings and access controls that allow travel providers to adjust what information is shared and with whom based on specific service contexts. The system adapts data sharing parameters in real-time, enabling flexible service integration while maintaining granular control over information distribution
Solution Approach 2:
The patent applies different security and control mechanisms to different portions of data based on sensitivity and usage requirements. Critical personal information receives stronger protection and more restricted access, while less sensitive operational data can be shared more freely, enabling service integration with differentiated control levels
3Productivity
If existing systems attempt to match customer records across providers, then service coordination is improved, but security and privacy protection are insufficient
Solution Approach 1:
The patent replaces traditional mechanical data matching methods with cryptographic techniques including tokenization, hashing, and secure comparison algorithms. This substitution enables automated record matching across providers while ensuring that raw personal data never needs to be exposed or compared in plaintext, significantly enhancing privacy protection reliability
Data Source
AI summary
A cryptographically enforced data exchange is disclosed that enables an exchange of customer travel records between a plurality of travel providers while preserving customer privacy. The disclosed system receives customer travel data from publishers, and communicates a portion of the customer travel data to one or more subscribers in response to determining a customer match, without disclosing any protected data elements between the publisher and the subscriber.
