Biometrics System Privacy Protection via Wireless Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric systems face challenges in balancing security and privacy, particularly in the storage and authentication of biologic information, as existing solutions often compromise privacy to enhance security.
Innovation Solution
A biometric system that uses a wireless local communication apparatus to transmit and store biologic information securely, allowing only authorized administration of reference biologic information and deletion from the system after transmission, ensuring privacy protection through encryption and secure storage on portable devices like mobile-phones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biologic information is stored in a centralized biometrics system for authentication, then authentication security is improved, but privacy protection deteriorates due to potential unauthorized access and forgery
Solution Approach 1:
The patent extracts the stored reference biologic information from the centralized biometrics system by transmitting it to an outside device under private control. The administrator transmits the registered reference biologic information to an outside device, and the controller deletes the registered reference biologic information from the biometrics system after transmission, thereby removing the privacy risk while maintaining authentication capability.
Solution Approach 2:
The patent introduces an outside device as an intermediary that stores the reference biologic information instead of the centralized biometrics system. This outside device acts as a mediator between the authentication system and the stored biologic information, providing both security and privacy protection by being under private control while enabling authentication operations.
2Object-affected harmful factors
If reference biologic information is transmitted to outside devices for private storage, then privacy protection is improved, but authentication reliability may deteriorate due to potential loss of centralized control
Solution Approach 1:
The patent applies preliminary action by having the administrator register and transmit the reference biologic information to the outside device before authentication operations begin. The controller also performs preliminary deletion of the reference information from the biometrics system after transmission, ensuring that the outside device is properly configured and controlled before it handles sensitive biologic information.
Solution Approach 2:
The patent implements feedback mechanisms where the biometrics system receives authentication results from the outside device and can control access accordingly. The system maintains the ability to verify and manage authentication outcomes, ensuring reliability even though the reference information is stored externally.
3Ease of operation
If biologic information is permanently stored in the biometrics system for future authentication, then authentication convenience is improved, but privacy protection deteriorates due to continuous storage of sensitive data
Solution Approach 1:
The patent extracts the stored biologic information from the biometrics system by transmitting it to an outside device and deleting it from the original system. This allows authentication to continue using the outside device while eliminating the continuous privacy risk associated with permanent storage in the centralized system.
Solution Approach 2:
The patent applies discarding and recovering by deleting the reference biologic information from the biometrics system after it has been successfully transmitted to the outside device. The information is discarded from the centralized system but can be recovered or re-transmitted if needed, maintaining authentication capability while reducing privacy risk.

AI summary
In a biometrics system for a building entrance unlocking or a bank account authentication, reference information registered under administration by the system is transmitted to a room or mobile-phone for private storage, with the original reference information deleted from the system. Biologic information gotten upon authentication is transmitted through wireless system to the room or mobile-phone for comparison with the reference, the result being returned to the system. Or, the reference is tentatively sent back to the system for comparison with the gotten biologic information. The biologic information sent to mobile-phone also includes health control information for storage and display. Mobile-phone also can receive blood pressure information at a waiting lounge of medical institution though wireless local communication even if the main power shut down. The communication between the biometrics system and the mobile-phone is encrypted. The system includes sensor unit and protection unit, the abnormality thereof being separately checked.
