Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current password authentication methods are weak due to reliance on easily guessable and difficult-to-remember passwords, and traditional keyboards can cause musculoskeletal disorders like carpal tunnel syndrome, while existing authentication systems lack strong verification methods.
Innovation Solution
A keyboard with a built-in microchip that records keystroke-scan characteristics to create a unique digital signature for authentication, combined with ergonomic design to alleviate wrist strain, and additional biometric verification methods like fingerprint, voice, and signature scans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional password authentication is used, then ease of operation is improved, but reliability deteriorates due to easily guessable and difficult-to-remember passwords
Solution Approach 1:
The patent replaces traditional mechanical password entry systems with biometric authentication systems that capture physiological characteristics (fingerprint, voice, signature) and behavioral characteristics (keystroke dynamics, mouse movements). This substitution eliminates the need for users to remember complex passwords while providing more reliable authentication based on unique biological and behavioral traits that are difficult to replicate or steal.
Solution Approach 2:
The patent introduces biometric characteristics as an intermediary between the user and the authentication system. Instead of directly entering passwords, users provide biometric data (fingerprint patterns, voice recordings, signature dynamics) that serve as unique identifiers. This intermediary layer enhances reliability by using inherent biological traits while maintaining ease of operation through natural interaction methods.
2Ease of manufacture
If conventional keyboard design is used, then ease of manufacture is improved, but object-affected harmful factors worsen due to musculoskeletal disorders like carpal tunnel syndrome
Solution Approach 1:
The patent divides the keyboard into separate left and right sections that can be independently positioned and angled. This segmentation allows each hand to operate on its own section, reducing the need for wrist rotation and crossing. The modular design maintains ease of manufacture while enabling ergonomic adjustments to prevent musculoskeletal disorders.
Solution Approach 2:
The patent introduces dynamic and adjustable keyboard components, including split sections that can be repositioned, rotated, and angled to match individual user anatomy. The keyboard transitions from a fixed, static design to a dynamic, adaptable configuration that optimizes wrist and hand positioning, thereby reducing harmful factors while remaining manufacturable through modular assembly techniques.
3Ease of operation
If simple ID and password authentication is used, then ease of operation is improved, but reliability deteriorates due to easy interception
Solution Approach 1:
The patent combines multiple authentication factors into a composite authentication system. Instead of relying on a single password, it integrates biometric characteristics (fingerprint, voice, signature) with behavioral characteristics (keystroke dynamics, mouse movements) and traditional knowledge-based factors (passwords, PINs). This composite approach creates layered security that is much harder to intercept or replicate while maintaining user-friendly operation through natural biometric input methods.
Data Source
AI summary
Keyboard configurations are described. In embodiments, a keyboard includes a microcontroller to register key inputs, a memory to store time durations that correspond to the key inputs, and an algorithm that generates an input signature based on the time durations that correspond to the key inputs. The input signature can be used for user authentication and identity theft protection, and/or used to validate users for access to a computer system. The input signature may also include a watermark, a timestamp, or voice stamp for further security. An input system that includes a keyboard can provide multi-modal biometric protection by supplementing keystroke-scans with fingerprint, voice-scan, signature-scan and mouse-scan verification.
