Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Unauthorized access to wearable devices poses a challenge, allowing individuals to illegitimately perform actions such as payments or account access using the device.

Innovation Solution

Wearable devices collect physiological data to build a user's profile and authenticate the wearer by matching collected data with the authorized user's profile, preventing unauthorized access by comparing physiological signatures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional authentication methods are used, then device accessibility is maintained, but security against unauthorized access deteriorates

Engineering Contradiction:

ImprovesecurityVSAvoiduser input requirement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system uses the user's own physiological data to perform authentication automatically. The wearable device collects physiological data from the user and compares it with stored profiles without requiring manual intervention, making the system both secure and convenient.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces traditional mechanical authentication systems (keyboards, PIN entry, physical tokens) with a physiological-based authentication system. Sensors collect biological signals and compare them against stored profiles, eliminating the need for manual user input while maintaining high security.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If physiological data collection is implemented, then authentication reliability improves, but device complexity increases

Engineering Contradiction:

Improveauthentication accuracyVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The wearable device performs multiple functions: it collects physiological data for health monitoring purposes and simultaneously uses the same data for authentication. This multi-functionality reduces the need for separate authentication hardware while improving authentication reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines physiological data collection and authentication functions into a single integrated system. The same sensors that collect health data are used to extract authentication features, merging two functions into one cohesive system that reduces overall complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Methods, systems, and devices for operating a wearable device are described. The wearable device may determine that a user is wearing the wearable device. The wearable device may collect physiological data from the user based on determining that the user is wearing the wearable device. The wearable device may then determine an identity of the user based at least in part on the collected physiological data matching a physiological profile associated with the identity. The wearable device may then authenticate the user for an action by the wearable device that requires user authentication.
