Biometric Authentication via Segmented Access Rights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric information stored in electronic devices is vulnerable to illegal use once compromised, as it cannot be changed like passwords, making it susceptible to unauthorized access.
Innovation Solution
An electronic device with a processor, memory, and sensors generates biometric information, stores it securely, and transmits access right information to external devices, ensuring secure communication and authentication through encryption and authentication keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric information is stored in the electronic device for security purposes, then security reliability is improved, but vulnerability to unauthorized access increases
Solution Approach 1:
The patent divides biometric information into multiple segments and stores them in different locations (first electronic device and second electronic device). This segmentation ensures that even if one device is compromised, the complete biometric information remains secure, thus maintaining security reliability while reducing vulnerability to unauthorized access.
Solution Approach 2:
The patent introduces access right information as an intermediary mechanism that controls access to biometric information. This intermediary layer requires authentication and verification before allowing access, thereby improving security reliability while preventing unauthorized access.
2Ease of operation
If access right information is transmitted to external electronic devices, then ease of operation is improved, but security risk increases
Solution Approach 1:
The patent uses access right information as an intermediary that enables external devices to access biometric information only when proper authentication is provided. This maintains ease of operation for authorized users while preventing unauthorized access, thus balancing convenience with security.
Solution Approach 2:
The patent changes the state of access rights dynamically based on authentication results. When authentication succeeds, access rights are granted; when it fails, access is denied. This dynamic parameter change allows ease of operation for legitimate users while maintaining security against unauthorized access.
3Reliability
If biometric information is divided and stored in multiple devices, then security is improved, but device complexity increases
Solution Approach 1:
The patent segments biometric information and distributes it across multiple devices, which improves security through decentralization. The systematic approach to segmentation and the use of standardized access control mechanisms help manage the inherent complexity, making the distributed system more secure while keeping operational complexity manageable.

AI summary
A method of operating an electronic device and an electronic device are provided. The method includes generating biometric information using at least one sensor of the electronic device, and storing the generated biometric information in a memory of the electronic device, generating access right information relating to the biometric information, determining whether an external electronic device is connected to the electronic device, and when the external electronic device is connected to the electronic device, transmitting the generated access right information to the external electronic device.
