Iris Authentication System Reducing Load via Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Iris authentication systems face a significant increase in arithmetic operations and system load due to repeated authentication processes, which existing technologies fail to effectively mitigate.
Innovation Solution
An authentication system that tracks objects using a first capture device, detects candidates for biometric authentication, determines if previous authentication has been performed, and performs iris authentication only when necessary using a second capture device with a partial overlap in capture range, thereby reducing redundant calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If iris authentication is performed repeatedly for the same object, then authentication accuracy is maintained, but arithmetic operations and system load increase significantly
Solution Approach 1:
The system performs preliminary tracking of objects using a first capture device before biometric authentication. By continuously tracking objects and maintaining their identification status, the system prepares authentication data in advance, allowing rapid authentication decisions without repeated full authentication processes, thus reducing system load while maintaining accuracy
Solution Approach 2:
The patent extracts only the necessary authentication information from tracked objects. When an object is already identified through tracking, the system extracts only the biometric verification step rather than performing complete authentication again, reducing arithmetic operations while preserving authentication reliability
2Reliability
If iris authentication is performed for every detected candidate, then security is ensured, but processing time increases
Solution Approach 1:
The system performs preliminary tracking and object identification before authentication. Objects that are continuously tracked and identified are pre-marked as authenticated, eliminating the need for repeated authentication processing. This preliminary action maintains security by ensuring only tracked objects are authenticated while dramatically reducing processing time for repeated detections
Solution Approach 2:
The patent implements a skipping mechanism where already-authenticated objects are identified through tracking records and skip the authentication step entirely. The system rushes through the authentication process by jumping directly to verification of tracking continuity, maintaining security through the tracking record while reducing processing time by skipping redundant authentication calculations
3Device complexity
If a single capture device is used for both tracking and authentication, then device complexity is reduced, but capture range and precision are compromised
Solution Approach 1:
The patent segments the capture function into two specialized devices: a first capture device optimized for wide-area tracking and a second capture device optimized for detailed authentication. This segmentation allows each device to operate at optimal performance levels, with the first device providing broad coverage for object tracking and the second device providing high precision for biometric verification
Solution Approach 2:
The first capture device acts as an intermediary between wide-area monitoring and detailed authentication. It identifies and tracks objects of interest, then passes this information to the second capture device for authentication. This intermediary role allows the system to maintain both wide capture range and high authentication precision without requiring a single complex device
Data Source
AI summary
An authentication system according to one aspect of the present disclosure includes: at least one memory storing a set of instructions; and at least one processor configured to execute the set of instructions to: track an object included in a video captured by a first capture device; detect a candidate for biometric authentication in the object being tracked; determine whether biometric authentication has been performed for the candidate based on a record of biometric authentication performed for the object being tracked; and perform the biometric authentication for the candidate based on a video of an authentication part of the candidate when the biometric authentication has not been performed for the candidate, the video of the authentication part being captured by a second capture device having a capture range including a part of a capture range of the first capture device.
