Solution Overview

Problem

Existing authentication technologies are primarily passive, relying on security challenges and direct responses, which can be burdensome and not optimized for various scenarios, leading to inefficiencies and potential security vulnerabilities.

Innovation Solution

The implementation of active behavioral profile authentication, which involves receiving and analyzing active behavioral data from personal electronic devices to compare with pre-established profiles, thereby authenticating individuals based on their unique patterns of behavior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If passive challenge-based authentication is used, then security verification is achieved, but user burden increases and efficiency decreases

Engineering Contradiction:

Improveauthentication securityVSAvoiduser burden

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs authentication automatically without requiring active user participation. The personal electronic device continuously collects behavioral data and the system autonomously compares this data against stored profiles to authenticate the user, eliminating the need for manual password entry or biometric scanning while maintaining security.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system pre-collects and stores behavioral profiles during a setup phase, so that during actual authentication, only continuous passive monitoring is needed. The behavioral patterns are established in advance, enabling rapid comparison and authentication decisions without burdening the user during critical moments.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If passive challenge-based authentication is used, then security verification is achieved, but authentication efficiency decreases

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system continuously collects behavioral data in the background without interrupting the user's workflow. Instead of periodic authentication challenges that stop productivity, the system maintains continuous monitoring and processing of behavioral patterns, enabling seamless authentication that occurs transparently during normal device usage.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system replaces manual authentication mechanics (password typing, biometric scanning) with automated behavioral analysis. Machine learning algorithms process behavioral data streams automatically, substituting the mechanical interaction required in traditional systems with computational analysis that occurs without user intervention.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If direct response to security challenges is required, then authentication can be verified, but predictability increases and security decreases

Engineering Contradiction:

Improveauthentication verificationVSAvoidbehavioral uniqueness

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

Instead of presenting security challenges and analyzing responses, the system inverts the approach by continuously observing natural behavioral patterns and using these patterns for authentication. Rather than asking 'what would you do in response to this challenge?', the system observes 'what do you naturally do?' making the authentication based on unconscious habitual behaviors that are harder to predict or fake.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A computer-implemented method for authenticating an individual to one or more IoT devices. The method may include: receiving active behavioral data from the personal electronic device; retrieving an active behavioral profile corresponding to the individual; comparing the active behavioral data with the active behavioral profile; and authenticating the individual based at least in part on the comparison.
