Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric systems lack a secure and efficient method for temporary access transfer between users, potentially compromising security when a authorized user is unavailable.
Innovation Solution
A method and system that generates a temporary code using biometric data from a first user, which is combined with biometric data from a second user to create an access code, allowing temporary access to a computer system without compromising security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is used to ensure system security, then security is improved, but accessibility deteriorates when the authorized user is unavailable
Solution Approach 1:
The patent introduces a temporary access code as an intermediary mechanism that bridges the gap between biometric security requirements and user availability. When the primary user is unavailable, the temporary code serves as a mediator that allows authorized second users to access the system without compromising the biometric authentication framework. The code is generated through a secure process involving both users' biometric data, ensuring it acts as a legitimate intermediary rather than a security bypass.
Solution Approach 2:
The system dynamically changes the authentication parameter from requiring the primary user's biometric data to accepting a temporary code derived from combined biometric data of multiple users. This parameter change allows the authentication mechanism to adapt to different user availability scenarios while maintaining security through the cryptographic derivation of the temporary code from legitimate biometric sources.
2Ease of operation
If temporary access permission is granted to another user, then access availability is improved, but security deteriorates
Solution Approach 1:
The system performs preliminary action by generating the temporary access code only after verifying the primary user's biometric authentication. This ensures that the code creation process itself is secured by biometric verification, preventing unauthorized code generation. The preliminary biometric check establishes a trust foundation before the temporary access mechanism is activated.
Solution Approach 2:
The temporary access code is created as a composite credential combining elements from multiple sources: the primary user's biometric data, the second user's biometric data, and a random code. This composite structure ensures that the temporary code inherits security properties from all its components, making it more secure than a simple password while still enabling temporary access.
3Adaptability or versatility
If biometric data of multiple users is combined to create access codes, then accessibility is improved for temporary users, but device complexity increases
Solution Approach 1:
The authentication system is segmented into distinct functional modules: biometric data collection from the primary user, temporary code generation, biometric data collection from the second user, access code generation, and verification. This segmentation allows each module to handle a specific task independently, reducing the perceived complexity while enabling the versatile temporary access functionality.
