Pupil Movement Frequency Authentication for Low-Throughput Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional iris recognition user authentication systems require high processing capability, making them difficult to popularize due to the need for handling large amounts of data, and there is a need for a method that improves security and allows rapid and accurate authentication with low data throughput.
Innovation Solution
A user authentication apparatus and method using pupil movement, where the frequencies of objects on a screen and corresponding security keys are stored, and authentication is performed by detecting the frequency of the pupil's movement and matching it to the stored frequencies to recognize the security key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional iris recognition technology is used to improve security, then authentication security is improved, but processing capability requirements increase and data throughput increases
Solution Approach 1:
The patent extracts only the essential authentication information (pupil movement frequency) from the complex iris recognition process. Instead of processing entire iris images and patterns, the system isolates and processes only the frequency characteristic of pupil movement, dramatically reducing data volume while maintaining authentication security
Solution Approach 2:
The patent transforms the authentication approach by changing the measured parameter from static iris patterns to dynamic pupil movement frequency. This parameter change enables authentication with significantly reduced data processing requirements while maintaining high security standards
2Measurement precision
If conventional iris recognition technology is used to improve authentication accuracy, then recognition accuracy is improved, but data throughput increases
Solution Approach 1:
The system extracts only the critical frequency parameter from pupil movement data, discarding unnecessary image data and processing overhead. This extraction approach maintains recognition accuracy by focusing on the most discriminative feature while minimizing data throughput requirements
3Device complexity
If password input schemes are used, then processing capability requirements are low, but authentication security deteriorates
Solution Approach 1:
The patent replaces the mechanical interaction of password input (keypad pressing) with an optical detection system that measures pupil movement frequency. This substitution maintains low processing requirements while dramatically improving security by using biometric characteristics that are difficult to forge or guess
Data Source
AI summary
A user authentication apparatus and method using movement of a pupil is capable of rapidly and accurately performing authentication with high security by storing the respective frequencies of objects mechanically moving on a screen and security keys corresponding thereto, comparing a frequency detected from movement of a pupil gazing at any object with a frequency of the object, and performing the authentication based on a corresponding security key when the detected frequency is included in a predetermined range.
