Solution Overview

Problem

Trust methodologies using digital certificates are vulnerable to intrusion attacks, data loss, and internal incompetence due to reliance on unreliable or unsecure third-party certificate issuers.

Innovation Solution

A distributed trust authentication system that uses a public data store, such as a blockchain, to validate content authenticity and provider identity through digital signatures, eliminating the need for third-party certificate authorities by creating entries for recipients and calculating trust scores based on veracity indicators from multiple recipients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If third-party certificate issuers are used to validate content authenticity and provider identity, then trust authentication can be established, but the system becomes vulnerable to intrusion attacks, data loss, and internal incompetence

Engineering Contradiction:

Improvetrust authenticationVSAvoidintrusion attacks, data loss, information breach

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and eliminates the third-party certificate issuer from the trust authentication system. Instead of relying on external certificate authorities, the system uses a distributed ledger where content providers and recipients directly authenticate each other through cryptographic proofs and veracity indicators stored on the blockchain, removing the vulnerable intermediary component

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a blockchain-based distributed ledger as a new intermediary that is inherently more secure than traditional certificate issuers. This mediator provides immutable, transparent, and decentralized verification of content authenticity and provider identity through cryptographic mechanisms, replacing the vulnerable third-party certificate authority

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a distributed trust authentication system using blockchain is implemented, then security and reliability are enhanced by eliminating third-party dependencies, but the device complexity and infrastructure requirements increase

Engineering Contradiction:

Improvesecurity and trustworthinessVSAvoidsystem architecture

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent makes the blockchain ledger serve multiple functions simultaneously: it stores content authenticity verification data, maintains provider identity records, records veracity indicators from recipients, and provides the trust authentication mechanism itself. This multi-functionality reduces the need for separate specialized components, thereby managing complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Apparatuses, methods, systems, and program products are disclosed for distributed trust authentication. An apparatus includes a processor and a memory that stores code executable by the processor. The code is executable by the processor to receive content for a recipient from a content provider. The code is executable by the processor to receive an indicator of the veracity of the received content from the recipient of the content. The indicator of veracity may attest to an authenticity of the received content and an identity of the content provider. The code is executable by the processor to create an entry for the recipient in a public data store to validate that the recipient received the content. The entry may include a digital signature for the recipient and the indicator of the veracity of the received content.
