Dual Biometric Authentication Access Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access control systems are insecure as they lack verification beyond the possession of access instruments, leading to potential unauthorized access, and are inconvenient due to the need to manage multiple passwords and the risk of loss or theft of physical items like keys and cards.
Innovation Solution
A dual-stage biometric verification system that requires two distinct biometric samples (e.g., fingerprint and voice) to authenticate users, with stored templates and codes, ensuring secure access to secured resources by communicating device identification and authentication codes through a central database and remote stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional access control systems use single biometric authentication, then ease of operation is improved, but reliability is worsened due to false authorization rates
Solution Approach 1:
The patent divides the authentication process into multiple independent biometric stages (e.g., fingerprint recognition followed by iris recognition). Each stage acts as a separate verification layer, segmenting the overall authentication process to reduce false authorization rates while maintaining operational flow.
Solution Approach 2:
The patent transitions from single-dimensional authentication (one biometric trait) to multi-dimensional authentication (multiple biometric traits). This dimensional expansion adds depth to the verification process, creating a more robust authentication system that reduces false positives while preserving user convenience.
2Reliability
If dual-stage biometric verification is implemented, then reliability is improved by reducing false authorization rates, but device complexity is worsened
Solution Approach 1:
The patent combines multiple biometric recognition functions into a single integrated accessing device. The device merges fingerprint sensors, iris cameras, and processing units into one unified system, reducing the complexity that would arise from using separate devices for each biometric modality.
Solution Approach 2:
The accessing device is designed with multi-functionality, capable of performing multiple biometric recognition tasks (fingerprint, iris, and potentially other biometric types) within a single device. This universal design consolidates hardware and software resources, managing complexity while enhancing reliability.
3Reliability
If multiple biometric samples are required, then false authorization rates are reduced, but loss of time is worsened due to additional verification steps
Solution Approach 1:
The patent implements preliminary action by pre-enrolling and storing multiple biometric templates for each authorized user before the actual authentication process. During access attempts, the system quickly compares provided biometric data against pre-stored templates, reducing the time required for verification while maintaining multiple-stage security.
Solution Approach 2:
The system allows the authentication process to progress through stages efficiently by skipping unnecessary verification steps when earlier stages already provide sufficient confidence. If the first biometric match is highly confident, the system can rapidly proceed to or skip certain verification steps, reducing overall authentication time while still maintaining security.
Data Source
AI summary
A biometrically authenticated access control in which a wireless authentication signal is provided from a primary instrumentality of access, only after a dual-stage biometric verification of the user's identity is performed. In one embodiment, an accessing device includes memory for storing a device identification code and an authentication code, along with first and second biometric templates corresponding to biometric samples from a user. In another embodiment, an accessing device includes memory for storing a device identification code and more than one authentication code, for separate users, along with first and second biometric templates corresponding to biometric samples from multiple users. In order to gain access to a secured resource, a user undergoes first and second biometric sampling to generate biometric data to be compared with the first and second biometric templates.
