Biometric Data Encryption in Transport Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transportation systems lack secure and efficient methods for data management and authentication, particularly in vehicles, where sensitive information needs to be protected and accessed based on biometric verification to ensure privacy and safety.
Innovation Solution
A method and system where a vehicle encrypts data using a first biometric, decrypts it using a verified second biometric that is a continuum of the first, and provides the unencrypted data to the occupant, utilizing blockchain technology for secure data storage and smart contracts for permission management, ensuring secure data access and privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is encrypted and stored in the transport system, then data security and privacy are improved, but data access efficiency and speed are worsened
Solution Approach 1:
The system performs preliminary encryption of data using the occupant's biometric template before storage. When the occupant accesses the data, the biometric sensor captures the same biometric trait and generates the same encryption key, allowing immediate decryption without time-consuming key generation or authentication processes. The encryption key is derived in advance from the biometric template stored in the database, so when the occupant presents their biometric, the system can quickly verify and decrypt the data.
2Reliability
If biometric authentication is implemented for data access, then access security is improved, but system complexity and authentication time are worsened
Solution Approach 1:
The biometric template serves multiple functions: it acts as both the authentication credential and the encryption key generator. The same biometric data (fingerprint, facial recognition, iris pattern, etc.) that verifies the occupant's identity is also used to derive the encryption key for accessing encrypted data. This eliminates the need for separate authentication and decryption key management systems, reducing overall system complexity while maintaining high security standards.
3Ease of operation
If sensitive data is stored in the transport system, then data availability and convenience are improved, but privacy risks and security vulnerabilities are worsened
Solution Approach 1:
The system implements different quality levels of data protection based on the sensitivity and type of data. Sensitive personal information is encrypted using the occupant's biometric-derived key, while less sensitive data may be stored in plaintext or with lighter protection. The encryption strength and access controls are locally adapted to each data element's privacy requirements, allowing convenient access to non-sensitive data while maintaining strong privacy protection for sensitive information.

AI summary
An example operation includes one or more of encrypting, by a transport, received data based on a first biometric associated with an occupant, unencrypting, by the transport, the encrypted data, based on a verification of a second biometric, wherein the second biometric is a continuum of the first biometric, and providing, by the transport, the unencrypted data to the occupant.
