Blockchain Worksite Access Kiosk Using Optical Code Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of a central registry system and standardized format for professional training and certification documentation in high-risk industries leads to fraud and undermines workplace safety, as individuals without proper training are sent to high-risk jobs, increasing the rate of accidents and fatalities.
Innovation Solution
A blockchain-based system and kiosk device that securely issues and verifies professional documentation, using a database to compare individual documentation with worksite safety requirements, and a kiosk device to control access by scanning optical codes, ensuring compliance and preventing fraudulent documentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central registry system with standardized format and security features is implemented for professional documentation, then fraud prevention and verification reliability are improved, but system complexity and implementation cost increase
Solution Approach 1:
The patent uses optical codes (QR codes, barcodes) as simplified copies of complex blockchain verification data. Instead of requiring employers to access and verify the entire blockchain ledger, the system generates compact optical codes that encode essential verification information, making the system easier to implement while maintaining fraud prevention capabilities
Solution Approach 2:
The patent introduces an intermediary verification layer between the blockchain registry and the verification process. The optical code acts as an intermediary that bridges the gap between the complex blockchain system and simple verification needs, allowing employers to verify documentation authenticity without directly interacting with the complex blockchain infrastructure
2Reliability
If blockchain technology is used to create tamper-proof professional documentation registry, then fraud prevention is improved, but ease of operation and accessibility deteriorate
Solution Approach 1:
The patent creates simplified optical code copies of blockchain-verified documentation data. These optical codes can be scanned and verified using simple mobile devices, making the verification process accessible to employers without technical expertise while the underlying blockchain ensures security and tamper-proof verification
Solution Approach 2:
The patent replaces complex mechanical/technical verification processes with optical scanning. Instead of requiring employers to manually verify documentation against blockchain ledgers or use specialized software, the system substitutes this with simple optical code scanning that can be performed with standard smartphone cameras, dramatically improving ease of operation
3Reliability
If comprehensive professional documentation verification is implemented at worksite entry, then worker safety and compliance are improved, but access time and productivity are reduced
Solution Approach 1:
The patent performs documentation verification in advance by pre-generating optical codes that contain verification data. When workers arrive at the worksite, the verification has already been completed or can be instantly verified by scanning the pre-prepared optical code, eliminating lengthy on-site verification processes and maintaining both safety compliance and access speed
Solution Approach 2:
The patent uses optical codes as compact copies of comprehensive verification data. These codes can be scanned and validated in seconds, providing the same safety assurance as comprehensive verification but with dramatically reduced access time, thus resolving the contradiction between safety compliance and productivity

AI summary
According to various embodiments, a system for controlling the presence of one or more individuals at a worksite is disclosed. The system includes a kiosk device and a database. The kiosk device includes a scanning device configured to receive an optical code representing an individual. The kiosk device further includes a processing system configured to determine whether the identified individual can enter the worksite by comparing professional documentation of the identified individual with safety requirements of the worksite. The database includes professional documentation of potential worksite individuals that the processing system can access to determine whether the identified individual can enter the worksite.
