Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional password-based authentication is used, then ease of operation is maintained, but security is compromised due to eavesdropping and device compromise vulnerabilities
Solution Approach 1:
The patent replaces traditional mechanical/password-based authentication with biometric authentication using facial recognition and other biological characteristics. This substitution eliminates the need for users to manually enter passwords while providing more secure authentication that cannot be easily compromised by eavesdropping or device compromise.
Solution Approach 2:
The patent introduces a remote agent system that mediates between the user and the service provider. This intermediary captures biometric data, performs initial verification, and communicates with the service provider, thereby enhancing security without requiring the service provider to implement complex authentication mechanisms themselves.
2Reliability
If biometric authentication methods are implemented, then authentication security is improved, but device complexity increases due to requiring special hardware sensors
Solution Approach 1:
The patent designs the biometric authentication system to work with widely available hardware components that serve multiple functions. For example, the camera used for facial recognition can also be used for other applications, and the microphone used for voice recognition can serve other audio-related functions. This universality reduces the need for specialized hardware.
Solution Approach 2:
The system allows users to enroll and authenticate themselves using their existing personal devices without requiring the service provider to provide special hardware. The user's own camera, microphone, or other sensors are used, making the system self-service oriented and reducing hardware complexity requirements.
3Reliability
If multiple authentication methods are required, then security is enhanced, but ease of operation deteriorates due to increased user steps and data to remember
Solution Approach 1:
The patent combines multiple authentication factors (facial recognition, voice recognition, iris recognition) into a single unified authentication process. Instead of requiring users to perform separate authentication steps for each factor, the system integrates them into one seamless flow, maintaining security while improving ease of operation.
Solution Approach 2:
The system performs preliminary biometric data capture and processing during the authentication process itself, rather than requiring users to pre-register complex authentication data. The remote agent captures the necessary biometric information in real-time during login, reducing the burden on users to remember or manage multiple pieces of data.
4Reliability
If passwords are made more complex, then security against guessing is improved, but ease of operation worsens due to difficulty in creation, management, and remembering
Solution Approach 1:
The patent replaces the manual password creation and management system with automated biometric authentication. Instead of users creating and managing complex passwords, the system automatically captures and verifies biometric characteristics, eliminating the burden of password management while maintaining or enhancing security.
Data Source
AI summary
Methods, systems, and computer program products for authenticating an online user. Authentication involves sending a code from a server to a user device equipped with a source of illumination and a camera capable of capturing video imagery of the online user. The user device receives the code, modulates the source of illumination in accordance with the code, and captures video imagery of the user while the source of illumination is being modulated according to the code. The captured video imagery of the online user is sent to the server where it is analyzed to detect evidence of changes in illumination that correspond to the code. If good correspondence is found, the user may be authenticated. Similar methods may be applied to other biometric data. Applications of the authentication include identify validation, pseudonym verification, and distinguishing human from non human access attempts.
