Living Body Detection in Wireless Tag Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image authentication methods, such as face authentication, face challenges in distinguishing between a living person and a photograph, leading to potential impersonation issues and reduced authentication accuracy.
Innovation Solution
An information processing apparatus and method that combines wireless communication to authenticate a wireless tag with image capture and analysis to determine if the captured image is of a living person, using techniques like background subtraction, Haar-like features, and optical flow to differentiate between real and non-real entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image authentication is used to enable contactless user verification, then authentication convenience is improved, but authentication accuracy deteriorates due to inability to distinguish living persons from photographs
Solution Approach 1:
The patent introduces dynamic elements to static image authentication by detecting motion characteristics. The motion detection unit analyzes whether captured images contain motion components, and the living body determination unit uses this dynamic information to distinguish real persons from static photographs. This transforms the authentication process from purely static visual verification to dynamic verification that exploits the fundamental difference between living organisms and inanimate objects.
Solution Approach 2:
The patent introduces intermediate processing units between image capture and authentication decision. The motion detection unit acts as an intermediary that extracts motion information from captured images, and the living body determination unit serves as another intermediary that synthesizes motion detection results with image authentication results. These intermediary units bridge the gap between simple image capture and accurate living body verification.
2Measurement precision
If multiple authentication methods are combined to improve security, then authentication accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges image authentication and motion detection into a unified authentication system. The authentication result determination unit combines results from both the image authentication unit and motion detection unit to make the final authentication decision. This merging approach allows the system to leverage multiple verification mechanisms while maintaining a cohesive system architecture that manages complexity through integrated processing.
Solution Approach 2:
The capturing unit serves multiple functions: it captures images for both visual authentication and motion detection analysis. The image processing system performs dual roles by conducting both traditional image recognition and motion component analysis. This multi-functionality reduces the need for separate dedicated hardware components, thereby managing system complexity while maintaining multiple authentication pathways.
