Multi-device Gesture Authentication via Segmented Credentials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods, such as passwords and biometrics, are cumbersome, difficult to manage, and inaccessible to users with disabilities, especially on smaller devices and for secure accounts that require complex credentials.
Innovation Solution
A multi-device authentication system where a plurality of user devices work in concert to provide secure authentication through gestures, with devices implanted in the body or worn, communicating authentication information when specific motions or sequences are performed, ensuring only authorized access to accounts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passwords and biometric authentication are used, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent segments the authentication process into multiple independent devices (e.g., smartphone, smartwatch, laptop) distributed across different body locations. Each device contributes a portion of the authentication credential, and the complete authentication requires combining signals from multiple devices in a specific sequence, thereby maintaining security while simplifying the user experience.
Solution Approach 2:
The patent introduces an intermediary system that coordinates communication between multiple devices and the target system. This intermediary manages the authentication flow, verifies device identities, and processes the combined credential signals, reducing the operational burden on users while maintaining robust security.
2Reliability
If multiple devices are used for authentication, then security is improved, but device complexity increases
Solution Approach 1:
The patent employs universal authentication protocols that can be implemented across diverse device types (smartphones, watches, laptops, implants). Each device type maintains its native functionality while also serving as an authentication credential, eliminating the need for specialized hardware and reducing overall system complexity.
Solution Approach 2:
The patent uses digital representations or copies of authentication credentials stored across multiple devices rather than requiring complex physical security elements. Each device holds a cryptographic copy of the authentication key, and the system verifies authentication through cryptographic validation rather than complex physical verification.
3Reliability
If complex passwords are required, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces the mechanical act of typing complex passwords with gesture-based authentication. Users perform physical gestures (e.g., waving hand, circular motion) that are captured by motion sensors in the devices, substituting the cumbersome mechanical keyboard input with intuitive physical movements that are easier to perform, especially on small devices.

AI summary
A system and method uses multiple devices in concert as security for accessing an account. The system and method may use one or more security measures based on unique gestures, coordinated gestures between two devices, presence of multiple devices, sequence of actions, and other measures to prevent fraud. Additionally, these security measures may be rearranged or changed such that the devices may collaborate to provide access to multiple different accounts.
