Motion-Based Authentication for Lock Restriction Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing devices lack a simple and secure method to cancel restrictions set by lock functions, often relying on insecure authentication methods that can be vulnerable to shoulder hacking or require inconvenient bio-authentication.
Innovation Solution
An information processing system that uses a wearable terminal connected via Bluetooth or Wi-Fi to an information processing device, where the user cancels restrictions by shaking both devices, generating displacement data that is compared to determine similarity and authenticate the user's intent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods (password, biometric) are used to cancel lock function restrictions, then security is ensured, but the operation becomes complex or inconvenient
Solution Approach 1:
The patent replaces traditional mechanical authentication systems (keyboards, biometric sensors) with a motion-based authentication system using acceleration sensors. The system detects specific shaking patterns of the mobile device to authenticate the user and cancel lock restrictions, eliminating the need for physical interaction with authentication interfaces while maintaining security.
Solution Approach 2:
The patent changes the authentication parameter from static inputs (passwords, fingerprints) to dynamic motion parameters (acceleration patterns, shaking frequency, duration). By monitoring acceleration data and comparing it against predefined authentication patterns, the system achieves both security and operational simplicity through natural device manipulation.
2Ease of operation
If simple authentication methods are used to cancel lock function restrictions, then operation is simple, but security is compromised due to vulnerability to shoulder hacking
Solution Approach 1:
The patent replaces vulnerable visual authentication interfaces with motion-based authentication using acceleration sensors. This substitution eliminates the need for users to input credentials that can be observed by attackers, while the unique shaking pattern detection provides secure authentication through physical device manipulation that cannot be easily replicated or observed.
Solution Approach 2:
The system uses the device's own motion characteristics and acceleration patterns as the authentication mechanism. The mobile device authenticates itself through its unique response to shaking motions, eliminating the need for external authentication systems or interfaces that could be compromised by shoulder hacking.
3Reliability
If biometric authentication is used to cancel lock function restrictions, then security is enhanced, but the procedure becomes complex and time-consuming
Solution Approach 1:
The patent replaces complex biometric authentication systems (fingerprint scanners, facial recognition) with a simple motion-based system using acceleration sensors. The shaking pattern detection requires no additional hardware beyond what's already in the device and can be performed rapidly without the complexity of biometric processing, significantly reducing authentication time while maintaining security.
4Reliability
If multiple devices are required for authentication, then security is enhanced by ensuring both devices are present, but the operation becomes more complex
Solution Approach 1:
The patent merges the authentication functions of multiple devices into a unified motion-based system. Instead of requiring separate authentication steps for each device, the system uses the acceleration patterns from device handling to simultaneously verify the presence and control of multiple devices, simplifying the overall system architecture while maintaining enhanced security through distributed device verification.
