Face Authentication Workflow for Password-Protected User Properties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information access methods, such as PIN codes and OTP generation, lack robustness in ensuring secure and user-specific authentication, particularly when passwords are shared or compromised.
Innovation Solution
An information processing apparatus and method that utilizes face authentication by comparing a stored face image with a live image, generating passwords based on property and biometric information, and disabling passwords upon failed authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face authentication is implemented by storing face images in user properties, then security is improved, but device complexity increases due to additional storage and processing requirements
Solution Approach 1:
The face image data is nested within the user property structure, utilizing existing property storage mechanisms rather than creating separate dedicated storage systems. The authentication process nests multiple verification steps (password check, face image extraction, comparison) within a unified authentication framework, reducing overall system complexity while maintaining security.
Solution Approach 2:
The property storage system is made multi-functional by enabling it to store both traditional user information and biometric face images. The authentication system serves multiple purposes: verifying user identity through password, validating biometric data through face image comparison, and providing a unified authentication interface that handles both methods.
2Reliability
If passwords are required for accessing user properties, then security is improved, but ease of operation deteriorates due to password management burden
Solution Approach 1:
The system provides self-service authentication through face recognition, where the user's own biometric data serves as the authentication key. The automated face image comparison and verification processes eliminate the need for users to manually manage passwords, while the system automatically handles security validation.
Solution Approach 2:
The authentication system merges password-based authentication with biometric face recognition into a unified process. Both authentication methods are combined within the same property access mechanism, allowing users to benefit from both security and convenience without needing separate systems.
3Adaptability or versatility
If face images are stored in user properties, then authentication capability is improved, but information security risk increases due to potential exposure of biometric data
Solution Approach 1:
The system performs preliminary validation by requiring password authentication before allowing access to extract or process stored face images. This preliminary security check prevents unauthorized access to biometric data while still enabling legitimate authentication processes. The comparison operation is performed in a controlled environment that limits data exposure.

AI summary
An information processing apparatus includes: a password acquisition unit that acquires a password set for a property of a user; a first image acquisition unit that acquires a first image that is a face image of the user stored in the property, by using the password; a second image acquiring unit that acquires a second image that is a face image of the user by imaging a face of the user, and an authentication unit that performs face authentication of the user by collating/verifying the first image with the second image. According to the information processing apparatus, information may be properly managed by using the password.
