Authentication System Using Imaging Angle for Spoofing Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems that rely solely on face and environment images are vulnerable to spoofing due to the lack of consideration for imaging angle information, which can lead to false authentication.
Innovation Solution
An authentication system that acquires face information, environment information, and imaging angle information from images and uses this data to perform an authentication process, enhancing security by incorporating the angle at which the image was captured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is performed using only face information and environment information from images, then the authentication process is simple and fast, but the system becomes vulnerable to spoofing attacks
Solution Approach 1:
The patent introduces a new dimension of authentication by incorporating imaging angle information alongside existing face and environment information. This multi-dimensional approach adds a new parameter (imaging angle) to the authentication process, making it more difficult for attackers to spoof without compromising the simplicity of the overall system architecture.
Solution Approach 2:
The authentication system is segmented into multiple independent acquisition units: a first acquisition unit for face and environment information, and a second acquisition unit for imaging angle information. This segmentation allows each component to function independently while contributing to the overall security, maintaining system simplicity through modular design.
2Reliability
If imaging angle information is added to the authentication process, then spoofing resistance improves, but the amount of data to be processed increases
Solution Approach 1:
The patent merges the acquisition of imaging angle information with the existing image capture process. The imaging angle is obtained as additional metadata from the same imaging device, rather than requiring separate sensors or systems. This merging approach minimizes additional information processing load while enhancing anti-spoofing capability.
Solution Approach 2:
The imaging device serves multiple functions: capturing face information, capturing environment information, and providing imaging angle data. This multi-functionality reduces the need for additional dedicated components, thereby minimizing the increase in information processing load while improving authentication security.
3Measurement precision
If multiple types of information (face, environment, imaging angle) are collected, then authentication accuracy increases, but the system complexity increases
Solution Approach 1:
A single imaging device performs multiple functions by capturing face information, environment information, and imaging angle data simultaneously. This universal approach achieves high authentication accuracy through multi-parameter collection without increasing system structure complexity, as all data is obtained from one device rather than multiple specialized components.
Solution Approach 2:
The system performs preliminary acquisition of imaging angle information at the time of image capture, storing it alongside face and environment information. This preliminary action ensures that all necessary data is ready for authentication without requiring additional complex processing steps later, maintaining system simplicity while improving accuracy.

AI summary
An authentication system includes: a first acquisition unit that obtains face information and environment information of a target, from an image including the target; a second acquisition unit that obtains imaging angle information that is information indicating an angle when the image is captured; and an authentication execution unit that performs an authentication process on the target, on the basis of the obtained face information, the obtained environment information, and the obtained imaging angle information. According to such an authentication system, it is possible to properly perform the authentication process.
