Verification Record Printing with Data Clearance Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document generation systems lack the necessary security measures to ensure the integrity and separation of documents from different events, such as voter ballots and test papers, which can compromise the legitimacy of democratic processes and educational systems.
Innovation Solution
A method and system for securely generating document verification records using a multifunction print device that includes a print engine, scanner, and secure storage container, which prints and scans documents, generates unique document IDs, and ensures all data is cleared before processing new jobs, restricting communication to a single source, and uses encryption and tamper-evident seals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a print device processes multiple print jobs sequentially, then productivity is improved, but data from different events may be commingled compromising security
Solution Approach 1:
The system performs preliminary data removal actions before each print job by restricting the print device from processing future print jobs until all data associated with previous source documents is removed from the print device. This ensures data from different events cannot be commingled while maintaining efficient sequential processing.
2Reliability
If data removal procedures are implemented between print jobs, then data integrity is improved, but processing time increases
Solution Approach 1:
The system automatically manages data removal through self-service mechanisms where the print device itself restricts processing until data is removed, eliminating the need for manual intervention or separate data wiping operations. This integrates data integrity maintenance into the normal processing flow.
3Reliability
If the print device is restricted from processing future print jobs, then data security is improved, but device availability decreases
Solution Approach 1:
The system implements preliminary restrictions that are automatically lifted after data removal is confirmed. This ensures data security during processing while maintaining device availability for subsequent legitimate print jobs, balancing security with productivity.
Data Source
AI summary
Methods for providing security in a document printing process are disclosed. In various embodiments, when a system comprising a print device receives source document files, then before printing it may ensure that the system satisfies various security conditions before it will print verification document sheets based on the source document files. For example, the system may require that data from all prior print jobs be cleared from the memory. The system also may require that the print device be restricted from external communications, browser application usage, or both. After printing all verification document sheets for all of the source electronic document files, the system may restrict the print device from processing any future print jobs until all data associated with the source electronic document files and the verification document sheets have been removed from the print device.
