Solution Overview

Problem

Traditional authentication methods rely on static user credentials that are susceptible to attacks and require network connectivity, making them vulnerable and inconvenient, especially in offline conditions.

Innovation Solution

A digital identity construct database is used to determine offline conditions and generate authentication tokens based on prior authentication credentials, leveraging both static and dynamic user attributes to authenticate users proactively without network connectivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional authentication methods using static credentials are used, then authentication can be performed with simple infrastructure, but the system becomes vulnerable to attacks and requires constant network connectivity

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent transforms static authentication credentials into dynamic ones by continuously evolving the digital identity construct using blockchain technology. The authentication credentials change over time based on new blocks added to the blockchain, making the system dynamic and resistant to attacks while maintaining security without requiring constant network connectivity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs preliminary actions by storing authentication credentials offline on the user's device before network connectivity is needed. The digital identity construct is cached locally, allowing the user to authenticate even when offline, thus preparing the system in advance for potential network unavailability.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If network connectivity is required for authentication, then centralized verification can be performed, but the system becomes unavailable during offline conditions

Engineering Contradiction:

Improveauthentication availabilityVSAvoidoffline operation capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system caches the digital identity construct and authentication credentials locally on the user's device before network connectivity is needed. This preliminary storage of authentication data enables the user to authenticate even when offline, thus preparing the system in advance for potential network unavailability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The blockchain serves as an intermediary that enables offline authentication. By storing authentication credentials on the blockchain and caching them locally, the system creates an intermediary layer that allows verification without constant network connectivity to the central server.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of manufacture

If static user credentials are used, then authentication is simple to implement, but the credentials become susceptible to exhaustive searching attacks

Engineering Contradiction:

Improveauthentication implementation easeVSAvoidvulnerability to attacks

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameters of authentication credentials over time by incorporating new blockchain blocks into the digital identity construct. This parameter change ensures that credentials are never static, making exhaustive searching attacks ineffective while maintaining ease of implementation through automated blockchain integration.

Inventive Principle:

Principle #35Parameter changes

AI summary

A method, apparatus, and computer program product for proactive offline authentication are provided. An example method includes determining a current offline condition of a computing device at a first time and determining a prior online condition of the computing device at a second time that is earlier than the first time at which the computing device generated second authentication credentials based upon one or more user attributes obtained from a digital identity construct database associated with a first user at the second time. The method further includes obtaining, at the first time, first authentication credentials associated with the first user and determining a discrepancy between the first and the second authentication credentials. In response to the determined discrepancy, the method includes generating an authentication token based upon the second authentication credentials for authenticating a first user device of the first user with the computing device.
