Sequential Biometric Verification Using Ordered Multi-Input Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fingerprint recognition technologies in security systems are vulnerable to fake fingerprints and lack sufficient security for high-level access control, as they only verify a single fingerprint without ensuring the authenticity of the user.
Innovation Solution
Implement a sequential biometric verification process that requires a predefined sequence of varying biometric inputs, such as fingerprints, facial recognition, or ocular scans, allowing users to choose when to provide additional inputs, and verifies both the correctness and order of these inputs before granting access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single fingerprint verification is used, then the ease of operation is improved, but the reliability of security is worsened
Solution Approach 1:
The verification process is segmented into multiple sequential biometric checks rather than a single verification step. The system divides the authentication process into a sequence of fingerprint verifications (first, second, and third fingerprints) that must all succeed, thereby maintaining ease of operation while significantly improving security reliability through segmented verification stages
2Reliability
If multiple biometric inputs in a sequence are required, then the reliability of security is improved, but the device complexity is worsened
Solution Approach 1:
The verification process dynamically adapts based on verification outcomes. After each successful fingerprint match, the system dynamically determines whether to request additional biometric inputs or proceed to the next stage, making the complexity conditional rather than fixed. This dynamic approach improves security reliability while managing device complexity through adaptive process control
3Reliability
If sequential biometric verification is implemented, then the reliability of security is improved, but the loss of time is worsened
Solution Approach 1:
The system performs preliminary biometric verifications in sequence, where each successful verification prepares the system for the next stage. By conducting verifications sequentially with predetermined logic, the system reduces overall verification time compared to parallel processing while maintaining high security reliability through multiple verification layers

AI summary
This disclosure is directed to a sequential biometric verification system and process. A device receives (502) a first biometric input and determines a match with a first predetermined biometric input of a verification sequence. The device provides (504) a first prompt that includes a request for a next biometric input user selection or a complete verification sequence user selection. The device receives the next biometric input user selection in response to the first prompt and a second biometric input, and then determines a match with a second predetermined biometric input of a verification sequence. The device provides a second prompt. The device receives the complete verification sequence user selection in response to the second prompt. Upon determining that at least the first and second biomet-ric inputs (508) and the order of inputs match the predetermined biometric inputs of the verification sequence (510), the device enables receiving a user command.
