Remote Client Authentication for Off-Network Distributed Ledger Access

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users are often required to authenticate via a network to access resources, which is not feasible when they lack network access or prefer not to connect.

Innovation Solution

A system using a remote client with a distributed ledger stored locally on client devices, enabling off-network access by capturing transaction information, determining device identifiers, retrieving credentials, unlocking ledger access, and terminating sessions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users authenticate via network to access resources, then access security is improved, but network connectivity requirement increases

Engineering Contradiction:

Improveaccess securityVSAvoidnetwork connectivity requirement

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary authentication and credential verification before network access is required. The remote client device stores authentication credentials locally and can verify user identity offline, enabling access without real-time network connectivity. The network connection is only established after successful local authentication to retrieve or validate credentials.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a remote client device as an intermediary between the user and the resource access system. This client device stores distributed ledger credentials locally and acts as a mediator that can authenticate users offline, then communicate with the entity system when network access is available. The intermediary enables decoupling of authentication from network connectivity requirements.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If distributed ledger credential is stored on client device, then off-network access capability is improved, but device security requirement increases

Engineering Contradiction:

Improveoff-network access capabilityVSAvoiddevice security requirement

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system creates a copy of the distributed ledger credential and stores it locally on the remote client device. This copy enables offline authentication capabilities without requiring continuous network access to the entity system. The credential copy is secured using cryptographic methods and can only be used for authentication purposes, enabling off-network access while maintaining security through cryptographic protection rather than physical security measures.

Inventive Principle:

Principle #26Copying

AI summary

Systems, computer program products, and methods are described herein for off-network access to resources using a remote client. The present invention is configured to receive, from one or more client devices, an off-network resource access request from a user; establish one or more network sessions with the one or more client devices; determine, via the one or more network sessions, one or more device identifiers associated with the one or more client devices; retrieve, from an internal repository, a distributed ledger credential associated with the distributed ledger stored on the one or more client devices; unlock, via the one or more network sessions, access to the distributed ledger for the user via the one or more client devices using the distributed ledger credential; and terminate the one or more network sessions in response to unlocking access to the distributed ledger for the user.
