2D Barcode System for Secure Data Transmission Without Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users without communication capabilities, such as internet or wireless connections, face challenges in securely delivering self-identifying information to recipients, particularly in scenarios involving pay-per-view services and other data transactions.
Innovation Solution
An end-user device generates a 2D barcode, like QR codes or Data Matrix, that includes user and device identification, activity data, and security elements, which can be scanned by an internet-enabled device to transmit information securely, even without direct internet access, using smart card interfaces and digital signatures for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users without communication capabilities attempt to deliver self-identifying information, then security and authentication are compromised, but using traditional communication methods requires internet or wireless connectivity which these devices lack
Solution Approach 1:
The patent introduces a camera as an intermediary device that captures images of displayed barcodes. This mediator enables communication between devices without direct connectivity, allowing the end-user device to transmit identification and transaction information securely through visual capture rather than electronic communication protocols
Solution Approach 2:
The system creates visual copies of data in the form of barcodes that can be scanned and transmitted. Instead of requiring direct digital communication, the information is copied into a visual format (barcode image) that can be captured by another device's camera, enabling data transfer without traditional communication interfaces
2Ease of operation
If manual reporting of technical issues or purchases is required, then user effort and time increase, but automated systems require communication capabilities that disabled devices lack
Solution Approach 1:
The system enables self-service by automatically generating barcodes that contain all necessary transaction and identification information. The end-user device autonomously prepares the data in barcode format without requiring user intervention for manual reporting, and the scanning device automatically captures and processes the information, eliminating the need for users to manually communicate technical issues or purchases
3Reliability
If direct internet connection is required for secure data transmission, then security is improved, but device complexity and connectivity requirements increase
Solution Approach 1:
The patent extracts the communication function from the end-user device itself and relocates it to the scanning device. The end-user device only needs to display barcodes locally without requiring internet connectivity, while the scanning device (which has communication capabilities) performs the data transmission. This separation removes the connectivity burden from the constrained device while maintaining security through controlled data generation
