Biometric Authentication for Trust-Based User Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portal sites face challenges in maintaining user openness while preventing anonymous users from exploiting services, as conventional authentication methods are vulnerable to false identities and anonymity, leading to decreased user trust and engagement.
Innovation Solution
A biological information authentication system that uses a device with a biological information memory unit, user group information confirmation unit, and authentication unit to verify trust relationships between users, ensuring only users with established trust relationships are authenticated, utilizing biometric data such as face, fingerprint, or iris information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all private information of users is opened to each other, then user openness is improved, but user safety and trust are worsened
Solution Approach 1:
The patent segments user information into public information and private information. Public information (user ID, profile) is openly shared to maintain portal openness, while private information (biological data, personal details) is protected and only accessible through authenticated trust relationships. This segmentation allows the system to simultaneously achieve user openness and safety by controlling the flow of different information types.
2Ease of operation
If conventional authentication methods are used, then user registration is simplified, but vulnerability to false identities and anonymity is worsened
Solution Approach 1:
The system performs preliminary authentication using biological information before allowing users to access the portal. During registration, users provide biometric data (fingerprint, facial recognition, iris scan) which is verified and stored as their unique authentication credential. This preliminary action ensures that only verified individuals can register, preventing false identities while maintaining ease of operation through automated biometric verification.
Solution Approach 2:
The patent replaces conventional mechanical authentication methods (passwords, ID cards) with biological information-based authentication. Instead of relying on memorizable secrets or physical documents that can be stolen or forged, the system uses unique biological traits that are difficult to replicate. This substitution significantly enhances authentication security while maintaining user convenience through contactless or minimal-contact verification processes.
3Adaptability or versatility
If invitation method is used to secure openness, then user selection is improved, but false identities and anonymity are worsened
Solution Approach 1:
The patent introduces biological information as an intermediary that objectively verifies user identity. Instead of relying on subjective invitation processes where users can feign identities, the system uses biometric authentication as an impartial mediator that conclusively identifies the actual person. This intermediary mechanism ensures that only genuine individuals can be invited and registered, eliminating the possibility of false identities while preserving the selective nature of the invitation process.

AI summary
A biological information authentication device is provided with a biological information memory means, a user group information confirmation means, a biological information registering means and an authentication unit. The user group information is the information representing a trust relationship among a plurality of users; the biological information memory unit associates each biological information extracted from a plurality of users with the user group information and stores them. The user group information confirmation unit receives a determination as to whether or not a trust relationship exists among a plurality of users from whom the biological information is extracted and confirms the relationship between users. The biological information registering unit matches the user group information and stores each biological information extracted from each user in association with the biological information memory means.
