Face Authentication Registration Guidance System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication methods for information processors, such as game consoles, often require users to enter passwords, which can be time-consuming and energy-intensive, and may not be suitable for games that reflect user motion without the need for input devices.
Innovation Solution
An information processor equipped with a face authentication system that includes a captured image display, guidance display, and registration processing sections, allowing users to efficiently register face identification data by rotating their heads in various directions relative to an imaging device, enabling simple and easy login without the need for input devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication using password is implemented, then security is ensured, but user time and energy consumption increase
Solution Approach 1:
The patent replaces the mechanical interaction of typing passwords with an optical recognition system. The imaging device captures facial images, and the processing unit automatically extracts facial features and compares them against stored data, eliminating the need for manual password entry and reducing user time and energy expenditure while maintaining security through biometric verification.
2Ease of operation
If face authentication system is implemented, then user authentication becomes simple and easy, but accurate recognition of tilted or angled faces becomes difficult
Solution Approach 1:
The patent implements a dynamic face registration process where the system guides users to rotate their faces through various angles and positions. The imaging device captures multiple facial images at different orientations, and the processing unit processes these varied-angle images to create comprehensive facial feature data, enabling accurate recognition regardless of the user's face orientation during authentication.
Solution Approach 2:
The patent extends face recognition from a single 2D plane to multiple spatial dimensions by capturing facial images at various angles and rotations. The system guides users to move their faces through different orientations in 3D space, capturing facial features from multiple perspectives, which enables accurate recognition even when the user's face is tilted or angled during authentication.
3Measurement precision
If face identification data is registered at multiple angles, then recognition accuracy improves, but registration process complexity increases
Solution Approach 1:
The patent implements a feedback-based registration guidance system that provides real-time visual feedback to users during the face rotation process. The display device shows guidance information indicating the current face orientation and the target orientation, allowing users to adjust their face position iteratively. This feedback mechanism simplifies the registration process by making it intuitive and easy to follow, despite requiring multiple angular captures.
Solution Approach 2:
The patent performs preliminary face capture and processing during the registration phase, capturing multiple angled images and pre-processing them to extract facial features before actual authentication occurs. This preliminary action prepares comprehensive facial data in advance, so that during authentication, the system can quickly compare against pre-processed multi-angle data without requiring complex real-time processing.
