Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing iris and retina authentication systems are limited to bulky, portal-based devices that provide one-time authentication, failing to continuously verify user identity and access levels, especially in dynamic environments like meetings or restricted areas with varying clearance levels.
Innovation Solution
A wearable system that includes a head-mounted retina/iris scanner, mobile computing device, position determining device, display, and communication interface, enabling continuous authentication based on user location and access privileges, with optional voice authentication and biometric data analysis for fatigue detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If portal-based iris/retina scanning systems are used, then authentication reliability is improved, but device portability and ease of operation deteriorate
Solution Approach 1:
The system divides the authentication function into multiple components: a wearable head-mounted scanner for biometric capture, a mobile computing device for processing and authentication decisions, and a communication interface for access control. This segmentation allows the authentication capability to be distributed across portable devices rather than requiring a single bulky portal system.
Solution Approach 2:
The patent replaces the mechanical portal-based scanning system with an optical/electromagnetic system using infrared illumination and image sensors mounted on the user's head. This substitution enables authentication to occur in the air space around the user rather than requiring physical passage through a fixed scanner.
2Device complexity
If point-in-time authentication is used, then system complexity is reduced, but security and reliability deteriorate
Solution Approach 1:
The system implements continuous authentication by repeatedly capturing iris/retina images and comparing them against stored templates at regular intervals. This continuous verification ensures that the authenticated user remains the same throughout the session, preventing unauthorized access even if initial authentication was compromised.
Solution Approach 2:
The system uses feedback from the authentication results to control access rights. After each authentication cycle, the system determines whether the current image matches the stored template and uses this feedback to grant or deny access to information and resources. The feedback loop continues throughout the session, dynamically controlling access based on ongoing verification.
3Ease of operation
If uniform information display is provided to all attendees, then ease of operation is improved, but information security and adaptability deteriorate
Solution Approach 1:
The system provides different information and access rights to different users based on their authentication results and clearance levels. Each user receives customized information relevant to their role and security clearance, rather than uniform information for all attendees. This local differentiation ensures that sensitive information is only accessed by authorized individuals.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous user authentication and access control across various environments, ensuring that users are only granted access to information and resources commensurate with their clearance levels, while reducing the risk of unauthorized access through frequent and adaptive verification processes.
Implementation Method 1
Iris recognition uses (video) camera technology with subtle near infrared illumination to obtain images of the visible details of the iris
Implementation Method 2
A retinal scan is performed by casting an unperceived beam of low-energy infrared light into a person's eye... The amount of reflection of this beam of light varies during the scan
Implementation Method 3
The amount of reflection of this beam of light varies during the scan since retinal blood vessels absorb light more readily than the surrounding tissue
