Sequential QR Code System for Device-Specific Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing QR code implementations lack a mechanism to easily and inexpensively detect fake QR codes, which can lead to users being redirected to unauthorized websites and potentially compromising their information.
Innovation Solution
The introduction of a sequential QR code (SQR code) system, where each scan provides a different user experience based on sequential configuration and targeting settings, allowing for dynamic content delivery and administrative authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a static QR code is used, then the QR code can be scanned without network access and at any time, but the encoded data is the same and cannot be tailored to specific end user devices
Solution Approach 1:
The patent implements a dynamic QR code system where the decoded URL redirects to different content based on device characteristics. The system dynamically determines content delivery based on device type, operating system, and other metadata, allowing the same QR code to provide customized experiences for different devices while maintaining the static code structure for easy scanning.
2Adaptability or versatility
If a dynamic QR code is used, then the linked data can be retrieved and tailored to device type, but the QR code requires network access to function
Solution Approach 1:
The patent performs preliminary actions by pre-configuring redirect rules and content delivery logic on the server side before the QR code is scanned. When a device scans the QR code, the system has already prepared the device-specific content delivery mechanism, allowing immediate redirection without requiring real-time network access for content generation, thus maintaining both adaptability and accessibility.
3Productivity
If a QR code is printed on physical media, then it can be widely distributed, but there is no way to verify if the QR code is authentic or has been tampered with
Solution Approach 1:
The patent implements a feedback mechanism where the system monitors and tracks QR code scans, redirect patterns, and device responses. This feedback loop allows administrators to detect unusual patterns that may indicate tampering or fraudulent use, providing ongoing verification of QR code authenticity while the codes remain widely distributed on physical media.
4Loss of information
If more data is encoded in a QR code, then more information can be provided, but the QR code becomes denser and harder to scan
Solution Approach 1:
The patent extracts the bulk of data from the QR code by encoding only a short URL in the QR code itself, while storing the actual content and device-specific information on a remote server. This extraction approach allows the QR code to remain simple and easily scannable, while still providing access to extensive information through the redirect mechanism.
Data Source
AI summary
A system method for delivery of predetermined administrator user content triggered after scanning a sequential QR code with a device. A UUID generated and is retrieved from the device based on a request received from the device. A trigger ID is obtained from the device based on the request received from the device. A previously created trigger configuration is fetched which trigger configuration provides a delivery setting. Content is then selectively delivered based on target matches with the fetched trigger configuration. The delivered content is the predetermined user content only if the retrieved UUID matches a previously stored UUID for the device.
