Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods (passwords, ID cards) are used, then ease of operation is maintained, but security reliability deteriorates due to risks of forgetting passwords, losing cards, and susceptibility to replay attacks
Solution Approach 1:
The patent replaces traditional mechanical authentication systems (passwords, ID cards, fingerprint scanners) with a brain-computer interface that measures electrical brain activity. This substitution uses a fundamentally different measurement approach (electroencephalogram signals) to achieve both high security and user convenience, as brainwave patterns are difficult to replicate and the system is contactless.
Solution Approach 2:
The patent changes the authentication parameter from physical/biological traits (fingerprints, facial features) to electrical brain activity patterns. By measuring electrical parameters (voltage fluctuations in EEG signals) rather than physical characteristics, the system achieves enhanced security while maintaining ease of operation, as users simply need to focus on visual stimuli without physical contact.
2Reliability
If biometric authentication systems (fingerprint, facial recognition) are used, then remembrance and misplacement issues are resolved, but security reliability deteriorates due to susceptibility to replay attacks and disclosure of private biometric information
Solution Approach 1:
The patent replaces contact-based biometric systems (fingerprint scanners, facial recognition cameras) with a non-contact brain-computer interface. This substitution eliminates the physical contact point that vulnerable systems exploit for replay attacks, as brainwave measurement requires no physical interaction between the user and the device.
Solution Approach 2:
The patent introduces visual stimuli as an intermediary between the user and the authentication process. The user focuses on specific visual elements displayed on a screen, and the system measures brain activity in response to these stimuli. This intermediary approach allows authentication without direct physical contact, enhancing security against replay attacks while maintaining system manageability.
3Reliability
If brain-computer interface authentication is implemented, then security reliability and resistance to replay attacks are improved, but device complexity increases due to the need for neurological headsets and signal processing systems
Solution Approach 1:
The patent employs a neurological headset that serves multiple functions: it displays visual stimuli to the user, records brain activity signals, and provides feedback during the authentication process. This multi-functionality reduces the need for separate components, thereby managing system complexity while maintaining high security performance.
Solution Approach 2:
The patent combines the stimulus presentation and signal recording functions into a single integrated brain-computer interface system. By merging these functions, the system reduces the number of separate components needed, managing complexity while achieving secure authentication through correlated brain activity measurement.

AI summary
Described herein relates to a system of and method for automatically authenticating an identity of a user, via a brain-computer interface, to allow the user access to at least one application of a computing device. The authentication optimization system may be configured to allow at least one user to register and/or login to an application, a computing device, and/or a program. Additionally, the authentication optimization system uses a machine learning and/or classifying algorithm for classification of the brain data and/or prediction of the correct password of the user. The authorization optimization system may also be configured to synchronize brain activity to the at least one user, such that each login may be correctly correlated to the user, based on a predetermined accuracy threshold, eliminating fraudulent and/or unauthorized login via false identification, or the like.
