Barcode Linked Data Retrieval for Printed Forms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for capturing data from printed applications are labor-intensive, error-prone, and dependent on print quality, making them costly and inefficient.
Innovation Solution
An electronic and paper combined data submission, printing, and retrieval method that encrypts user-entered data on a client terminal before printing, using a unique identification code that allows secure retrieval from a remote storage server, reducing reliance on print quality and manual entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If OCR or manual typing is used to capture data from printed applications, then data can be extracted, but the process is labor-intensive and error-prone
Solution Approach 1:
The patent applies preliminary action by capturing and encrypting data electronically at the source (on the client terminal) before the document is printed. This electronic capture happens at P2 in the flowchart, allowing the data to be stored in advance without requiring later extraction through OCR or manual typing, thus improving both efficiency and accuracy
Solution Approach 2:
The patent introduces an intermediary mechanism - a unique identification code (barcode/QR code) printed on the document that links to the electronically stored data. This code acts as a mediator between the physical printed document and the electronic database, allowing quick retrieval without reading or interpreting the document content itself
2Productivity
If traditional data capture methods are used, then data can be obtained, but the cost is high and manual labor is intensive
Solution Approach 1:
The system applies self-service by having the client terminal automatically encrypt and upload data to the server without manual intervention. The printed document carries its own identification code that automatically links to the stored data, eliminating the need for manual data entry or interpretation services
Solution Approach 2:
The patent replaces mechanical data capture processes (manual typing, OCR scanning of document content) with an electronic system that captures data once at the source and uses automated barcode/QR code recognition for retrieval, substituting human labor and complex optical recognition with simple code scanning
3Loss of time
If data is stored electronically, then retrieval speed improves, but data security may be compromised
Solution Approach 1:
The patent applies preliminary anti-action by implementing encryption of the data before it is stored on the server. The data is encrypted at P2 using a unique encryption code, and this encrypted form is what gets stored in the database, preventing unauthorized access even if the database is compromised
Solution Approach 2:
The patent applies local quality by using different quality levels for different parts of the system: the data is highly protected (encrypted) in the electronic storage, while the printed document contains only a simple identification code without sensitive information. This allows fast retrieval through code scanning while maintaining security through selective encryption
Data Source
AI summary
An electronic and paper combined data submission, printing, and retrieval method includes: completing an application in a client terminal, sending the user-entered data in the client terminal to a remote storage server; printing the completed application together with a barcode containing a unique identification code; retrieving the electronic data stored in the remote storage server by scanning said identification code. A system includes: a data encryption module; a data transmission module; an identification code module; a print module; a scan module; an analysis module; a data retrieve module; and a data decryption module.
