Portable Face Authentication Using Movement-Based Spoofing Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Face authentication systems using portable terminals are vulnerable to spoofing due to lack of attention from others, making it easy to use a face photograph or display for unauthorized access.
Innovation Solution
An information processing apparatus that integrates face and operation authentication, requiring the user to perform specific movements while holding the device, combining face image capture with positional tracking to verify both face and operation matches, thereby reducing spoofing risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If face authentication is performed using a portable terminal held by the user, then authentication convenience is improved, but spoofing vulnerability increases
Solution Approach 1:
The authentication process is divided into two independent segments: face authentication and operation authentication. The face authentication verifies the user's identity through facial recognition, while the operation authentication verifies that the user is physically present and controlling the device by performing specified operations (e.g., moving the device, pressing buttons). This segmentation ensures that both components must succeed for overall authentication to pass, thereby reducing spoofing vulnerability while maintaining convenience.
Solution Approach 2:
The patent merges face authentication and operation authentication into a unified authentication system. Both authentication modules work together to verify the user's identity and physical presence. The operation authentication unit specifically monitors device operations during the authentication process, combining this with facial recognition to create a more robust security mechanism that is difficult for attackers to bypass.
2Reliability
If operation authentication is added to verify physical presence, then spoofing resistance is improved, but authentication complexity increases
Solution Approach 1:
The operation authentication unit leverages existing device capabilities (camera, processor, display) for multiple purposes. The camera captures images not only for face authentication but also to verify the user's eyes are open and looking at the screen during operation authentication. The processor handles both facial recognition and operation verification. This multi-functionality approach reduces the need for separate dedicated hardware, thereby limiting the increase in device complexity while maintaining high spoofing resistance.

AI summary
An information processing apparatus includes an acquisition unit that acquires a face image of the target person, a face authentication unit that performs face authentication of the target person by using the face image, an operation instruction unit that issues an instruction to the target person to perform an operation while holding the information processing apparatus, an operation authentication unit that performs operation authentication of the target person based on the operation being performed according to the issued instruction and an actual operation including positional movement of the information processing apparatus, and a determination unit that determines that the authentication of the target person has succeeded when the face authentication has succeeded and the operation authentication has succeeded, and determines that the authentication of the target person has failed when at least one of the face authentication and the operation authentication has failed.
