Wearable Authentication via Sensor Signature Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile devices, such as smartphones and tablets, face limitations in form factor, which restrict true computing mobility due to their weight and volume, impacting user freedom, especially for physically active users, and require cumbersome authentication methods that are burdensome and insecure.
Innovation Solution
A wearable device-based authentication system that uses multi-modal sensing to detect user presence and interactions, employing interaction-based and context-based authentication methods to securely authenticate users across multiple devices with minimal manual intervention, leveraging sensors like accelerometers, GSR, and temperature sensors, and communication protocols like Bluetooth and Wi-Fi.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If mobile devices are made smaller to improve portability, then form factor is improved, but authentication security deteriorates due to limited space for secure hardware components
Solution Approach 1:
The authentication system is segmented into multiple independent components: a wearable device with biometric sensors and a mobile device with authentication processing. This segmentation allows the mobile device to remain small while the authentication security functions are distributed to the wearable device, resolving the contradiction between small form factor and authentication security.
2Reliability
If traditional authentication methods are used, then security is maintained, but ease of operation deteriorates due to manual authentication requirements
Solution Approach 1:
The authentication system implements self-service through automatic biometric verification. The wearable device continuously monitors biometric data and automatically authenticates the user without manual intervention. The mobile device receives and verifies authentication tokens automatically, eliminating the need for users to manually enter passwords or codes while maintaining security through multi-modal biometric verification.
3Reliability
If manual authentication methods are used, then security control is maintained, but productivity deteriorates due to time-consuming authentication processes
Solution Approach 1:
The system performs preliminary authentication actions by continuously collecting and processing biometric data in the wearable device before authentication is needed. Biometric templates are pre-processed and stored securely, and authentication tokens are generated in advance. When authentication is required, the pre-prepared data enables rapid verification without time-consuming manual input or complex processing.

AI summary
In some embodiments, computer implemented methods, systems, and non-transitory computer readable media determine a first comparison value based on a first comparison between a first sensor signature associated with first set of sensor data of a first device in a first context and a second sensor signature associated with second set of sensor data of a second device. The first comparison is associated with a first authentication type. It is determined whether the first comparison value satisfies a first threshold. It is determined that a user should be authenticated on the second device based on satisfaction of the first threshold.
