Multi-modal Authentication Evaluation System for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-modal authentication techniques are weak in authentication strength and fail to effectively evaluate and enhance authentication strength by incorporating additional authentication elements.
Innovation Solution
An information processing apparatus and method that evaluates multiple pieces of authentication information from various viewpoints using specific indices, and presents an evaluation result to the user to enhance authentication strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only audio signal authentication is used, then the authentication system is simple, but the authentication strength is weak
Solution Approach 1:
The patent combines multiple authentication elements (audio signal, image signal, operation history, sensor data) into a unified multi-modal authentication system. The evaluation unit integrates these diverse data sources to comprehensively assess authentication strength, thereby resolving the contradiction between authentication strength and system complexity by merging multiple weak authentication methods into a strong unified system.
Solution Approach 2:
The patent creates a composite authentication system that combines different types of authentication data (biometric audio, visual image, behavioral operation history, and sensor information) similar to how composite materials combine different substances to achieve superior properties. This composite approach enables high authentication strength while maintaining manageable system complexity through standardized evaluation protocols.
2Reliability
If multiple authentication elements are added, then authentication strength can be increased, but the authentication strength including other authentication elements is not evaluated
Solution Approach 1:
The patent segments the authentication evaluation into multiple independent viewpoints (authentication strength, security, privacy, usability) with specific evaluation indices for each. This segmentation allows comprehensive evaluation of multi-modal authentication elements without information loss, as each aspect is evaluated separately and then integrated to provide a complete authentication assessment.
Solution Approach 2:
The evaluation unit provides feedback mechanisms that assess each authentication element and their combinations across multiple viewpoints. This feedback loop ensures that when multiple authentication elements are added, their combined strength is systematically evaluated and communicated back to the system, preventing information loss about the overall authentication capability.
3Reliability
If multi-modal authentication is implemented, then authentication strength increases, but it is difficult to understand the evaluation results
Solution Approach 1:
The patent introduces an intermediary presentation processing unit that translates complex multi-modal authentication evaluation results into user-friendly formats. This intermediary layer converts technical evaluation data across multiple viewpoints into easily understandable information for users, resolving the contradiction between high authentication strength and ease of understanding evaluation results.
