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

VSEngineering 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

Engineering Contradiction:
Improvedevice sizeVSAvoidauthentication security
Core Design Contradiction:
Volume of moving objectVSReliability

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.

Inventive Principle:
Principle #1Segmentation

2Reliability

If traditional authentication methods are used, then security is maintained, but ease of operation deteriorates due to manual authentication requirements

Engineering Contradiction:
Improveauthentication securityVSAvoidauthentication convenience
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #25Self-service

3Reliability

If manual authentication methods are used, then security control is maintained, but productivity deteriorates due to time-consuming authentication processes

Engineering Contradiction:
Improveauthentication securityVSAvoidauthentication speed
Core Design Contradiction:
ReliabilityVSProductivity

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.

Inventive Principle:
Principle #10Preliminary action

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.
