Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Identity authentication systems face challenges in balancing security and convenience, particularly in mobile terminals where repeated authentication processes can lead to erroneous detections and resource wastage, degrading user convenience.
Innovation Solution
An identity authentication system that employs a photograph identity-theft detecting unit, collation timing control unit, and face feature information management to dynamically adjust authentication frequency and intensity based on detection rates, using a combination of face detection, feature extraction, and similarity indexing, while also considering user behavior patterns and environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identity authentication is configured to be repeated for strengthening security, then security is improved, but user convenience is degraded and calculation resources are wasted
Solution Approach 1:
The patent applies dynamics by making the authentication frequency adjustable rather than fixed. The collation timing control unit dynamically changes the frequency of repeated authentication based on detection results from the photograph identity-theft detecting unit. When identity theft is detected, authentication frequency increases; when not detected, frequency decreases, thus adapting security levels to actual risks while maintaining convenience during normal use.
Solution Approach 2:
The patent changes the parameter of authentication frequency based on detection rates. The system monitors identity theft detection results and adjusts the collation frequency parameter accordingly. This parameter change allows the system to strengthen security when needed while avoiding excessive authentication during normal operations, thereby balancing security and convenience.
2Reliability
If identity authentication is configured to be repeated for strengthening security, then security is improved, but calculation resources are wasted
Solution Approach 1:
The system dynamically adjusts the authentication frequency parameter based on detection results. When identity theft is not detected, the collation frequency is reduced or suspended, minimizing calculation resource consumption. When detection occurs, frequency increases to strengthen security. This parameter adjustment directly addresses the resource waste problem while maintaining security effectiveness.
Solution Approach 2:
The system uses its own detection results to control its own authentication frequency. The collation timing control unit automatically adjusts authentication operations based on feedback from the photograph identity-theft detecting unit, eliminating the need for external control and enabling automatic resource optimization based on actual security needs.
3Reliability
If repeated identity authentication is performed, then security is strengthened, but erroneous detection such as authentication failure occurs easily
Solution Approach 1:
The patent applies dynamics by adjusting authentication frequency based on actual detection needs rather than using fixed repeated authentication. The collation timing control unit dynamically determines when authentication should occur based on photograph identity-theft detection results, avoiding unnecessary repeated authentication that could lead to erroneous failures while maintaining security when actually needed.

AI summary
According to one embodiment, an identity authentication system includes a detecting unit that detects an identity theft by determining whether a photographing target is a living body or a non-living body, a collating unit that performs identity collation based on a photographed image, and a control unit that controls execution timing of a detection process performed by the detecting unit and an identity collating processing performed by the collating unit and, in a case where the detection performed by the detecting unit is performed for a first number of times, performs the collation process performed by the collating unit, wherein the first number of times is set in consideration of a tradeoff between a required intensity of security and convenience of a user using the identity authentication system.
