Barcode Processing System for Selective Content Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The preservation of QR code information is compromised as the contents referenced by QR codes can change or become inaccessible, leading to loss of valuable data, especially since QR codes are not directly readable and their importance varies.
Innovation Solution
A method and system for classifying QR codes into categories based on importance, using a processor to detect QR codes, classify them as first or second class codes, and save the corresponding content only for the first class codes, employing a QR code processing system with a detector, classifier, saver, and repository, and optionally using pre-defined rules and weights to determine classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all QR codes are preserved, then information preservation is improved, but storage cost and time are increased
Solution Approach 1:
The patent segments QR codes into different classes (first class and second class) based on their importance and characteristics. This segmentation allows the system to apply different preservation strategies to different groups, preserving only the essential information from first class QR codes while discarding second class QR codes, thus resolving the contradiction between comprehensive preservation and storage efficiency
Solution Approach 2:
The patent applies local quality by treating different QR codes differently based on their specific characteristics. First class QR codes (which contain valuable, static information) receive full preservation treatment, while second class QR codes (which may contain dynamic or less valuable information) are discarded. This selective approach optimizes storage resource allocation
2Reliability
If QR code contents are saved, then information reliability is improved, but processing time is increased
Solution Approach 1:
The patent performs preliminary classification of QR codes into first class and second class before the actual preservation process. By pre-identifying which QR codes are worth preserving based on their characteristics and importance, the system avoids the time-consuming process of saving all QR code contents, thus reducing processing time while maintaining information reliability for critical data
3Loss of information
If QR code information is preserved, then data value is maintained, but storage complexity is increased
Solution Approach 1:
The patent simplifies storage complexity by segmenting QR codes into two distinct classes with different preservation requirements. This segmentation creates a clear, manageable structure where first class QR codes are preserved and second class QR codes are discarded, avoiding the complexity of managing all QR codes uniformly while ensuring valuable data is protected
Data Source
AI summary
Provided are techniques for barcode processing. A barcode is detected. Then the barcode is classified as any of a first class code that needs to be preserved and a second class code that does not need to be preserved. For the barcode classified as the first class code, a content referred to by the barcode is saved.
