Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital printing systems for secret files rely heavily on human intervention, leading to management confusion, difficulty in tracing fake or leaked copies, and increased risk of secret file exposure due to excessive human interactions.
Innovation Solution
A method and system that involves a secret file library for managing and controlling digital printing, where a source file is imported, printing control information is written, and page dot matrix data is processed to conceal system information, reducing human intervention and ensuring traceability through digital watermarking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If human intervention is used for printing management of secret files, then flexibility and adaptability are improved, but security and traceability deteriorate due to management confusion and difficulty in tracing leaked copies
Solution Approach 1:
The patent replaces the mechanical human intervention system with an automated digital printing control system. The system automatically manages secret file printing through computer-controlled processes, eliminating manual operations while maintaining flexibility through software-configurable parameters. This substitution resolves the contradiction by providing both automation (improving security) and configurability (maintaining flexibility).
Solution Approach 2:
The patent implements feedback mechanisms through digital watermarking and traceability systems. Each printed copy contains embedded identification information that provides feedback about the printing source and parameters. This feedback loop enables automatic tracking and accountability, improving security while maintaining system flexibility through programmable response protocols.
2Ease of operation
If human intervention is used for printing management, then ease of operation is improved for manual control, but device complexity increases due to excessive human interactions and management procedures
Solution Approach 1:
The patent implements self-service automation where the printing system automatically performs management functions without human intervention. The system autonomously controls file access, printing parameters, and traceability recording. This eliminates the complexity of manual management procedures while maintaining operational simplicity through user-friendly interfaces for essential controls.
Solution Approach 2:
The patent segments the printing management system into distinct functional modules: file access control, printing execution, watermark embedding, and traceability recording. Each module operates independently with defined interfaces, reducing overall system complexity while maintaining ease of operation through specialized, simplified control for each function.
3Productivity
If source file is accessible for printing, then productivity is improved, but security deteriorates due to easy copying and transferring of source files
Solution Approach 1:
The patent introduces an intermediary controlled printing system between the source file and the printing output. The system acts as a mediator that processes files through secure automated workflows, enabling high productivity through efficient automated handling while protecting security by eliminating direct human access to source files and preventing unauthorized copying through controlled data flow.
Data Source
AI summary
A method and system for controlling digital printing of a secret file is provided in this invention. The method comprises: obtaining a source file to be printed; importing the source file into a secret file library; generating a printing job for the source file and adding the printing job into a job list; writing printing control information of the source file into a standard file; after the printing is started, extracting page dot matrix data of the source file from the secret file library, and processing the page dot matrix data according to the printing control information; and transmitting the processed page dot matrix data to a numerical control device. Control management may be effectively realized throughout the printing process of the secret file, and the source file and the standard file cannot be copied without some professional skills in the printing process.
