Pupil Dilation Authentication via Challenge Prompt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user authentication methods, such as two-step authentication, often rely on physical devices that can be misplaced, damaged, or unavailable, and require additional hardware and data plans, which can be inconvenient and costly, while also being susceptible to password-related issues like forgetting or compromise.
Innovation Solution
A system and method for user authentication using pupil dilation response authentication, where a challenge prompt is displayed to record and store a user's pupil dilation response, allowing for subsequent authentication by comparing subsequent responses to the stored ones, eliminating the need for physical devices and passwords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two-step authentication with physical devices is used, then authentication security is improved, but device complexity and user cost increase
Solution Approach 1:
The patent replaces the mechanical/physical authentication system (smart cards, tokens, mobile devices) with a physiological-based authentication system that measures pupil dilation response. This substitution eliminates the need for external physical devices while maintaining security, as the pupil response is an internal physiological reaction that cannot be easily replicated or stolen.
Solution Approach 2:
The system uses the user's own physiological response (pupil dilation) as the authentication credential, eliminating the need for separate authentication devices. The user's body itself becomes the authentication mechanism, reducing device complexity while maintaining reliability.
2Reliability
If physical authentication devices are required, then authentication reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces the need to carry and use physical authentication devices with a non-intrusive physiological measurement system. The pupil dilation response is captured automatically through a camera or sensor without requiring the user to manually operate any authentication device, significantly improving ease of operation while maintaining security.
Solution Approach 2:
The authentication process leverages the user's natural physiological response without requiring active participation beyond viewing the stimulus. The system automatically captures and processes the pupil dilation response, making the process as convenient as looking at a screen while maintaining high security.
3Reliability
If additional authentication devices are implemented, then transactional security is improved, but loss of energy increases
Solution Approach 1:
The patent replaces communication-intensive authentication methods (such as SMS-based two-factor authentication or token verification requiring network communication) with local physiological measurement. The pupil dilation response can be captured and processed locally without requiring continuous network connectivity or additional data plan consumption, reducing energy loss while maintaining security.
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
This approach provides a secure and convenient authentication method that enhances user identity verification without the need for physical devices or passwords, offering improved transactional security and reducing costs associated with additional hardware and data plans.
Implementation Method 1
a recording component that records a pupil dilation response of the user's eye in reaction to viewing the challenge prompt
Data Source
AI summary
A user's emotion can be determined based on pupil dilation response to a challenge prompt. In response to an authentication request, a registered challenge prompt and an expected pupil dilation response can be retrieved. The challenge prompt can include one or more images or a video designed to cause a pupil dilation response in a user. The challenge prompt is displayed to the user and the user's pupil dilation response is captured. At least one user action of the user is monitored and an emotion is determined based on the at least one user action. The emotion is associated with the pupil dilation response.
