Solution Overview

Problem

Existing employment verification processes are inefficient, prone to inaccuracies, and vulnerable to cyber-attacks due to the manual nature of data retrieval and storage in centralized databases, which limits the transferability of employee records across employers.

Innovation Solution

A distributed blockchain system is implemented for secure and efficient storage and management of employment records, using cryptographic hashes to create a chain of data blocks that ensures data integrity and transparency across multiple network nodes, eliminating the need for a central trust authority.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If centralized databases are used to store employment records, then data storage and retrieval are simplified, but data security and integrity are compromised due to vulnerability to cyber-attacks and fraudulent modification

Engineering Contradiction:

Improvedata storage and retrievalVSAvoiddata security and integrity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent segments the centralized database into distributed blocks across multiple nodes in a blockchain network. Each block contains employment record data and is linked to the previous block through cryptographic hashing, creating a decentralized structure that maintains data accessibility while enhancing security through distribution across multiple independent nodes rather than a single vulnerable central repository

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces cryptographic hash functions as intermediaries between the original data and its storage form. Each block's hash is derived from its data and the previous block's hash, creating a chain of cryptographic intermediaries that verify data integrity without requiring direct access to the original data, thus protecting against fraudulent modification while maintaining verification capability

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If manual verification processes are used to contact previous employers, then data accuracy can be confirmed, but administrative work and time consumption increase significantly

Engineering Contradiction:

Improvedata accuracyVSAvoidadministrative work time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements self-service verification where the blockchain system automatically verifies employment record accuracy through cryptographic validation. When new employment data is added, the system automatically hashes the data, links it to previous blocks, and distributes it across the network, eliminating the need for manual verification processes while maintaining high data accuracy through automated cryptographic proof

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical manual verification process (human administrators contacting employers) with an automated cryptographic system. The blockchain's consensus mechanism and hash verification algorithms automatically validate employment records, substituting human administrative effort with automated computational processes that achieve the same accuracy goal without time consumption

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If employee records are stored in employer databases, then data security is maintained within the organization, but record transferability to new employers is limited

Engineering Contradiction:

Improvedata securityVSAvoidrecord transferability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal blockchain ledger that serves multiple employers and employees simultaneously. The same blockchain structure and verification mechanism work across different organizations, allowing employment records to be transferred between employers without leaving the secure blockchain environment. The system is designed to be employer-agnostic, with each employer's data contributing to a shared ledger that all authorized parties can access and verify

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent implements distributed copying of the blockchain across multiple nodes. When an employee changes employers, the employment record data is not physically transferred but rather the verification capability is copied across the network. The new employer can access and verify the employee's history through the distributed ledger, eliminating the need for physical record transfer while maintaining security through cryptographic verification

Inventive Principle:

Principle #26Copying
