Document Data Segmentation for Secure Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient method for securely transmitting and receiving confidential documents, particularly in scenarios where electronic postal services need to ensure document integrity and confidentiality across multiple image processing devices.
Innovation Solution
A document transmitting and receiving system that includes a printing unit, storage unit, and obtaining unit, where specifying information is used to associate documents with data parts, allowing secure transmission and reception of documents across multiple image processing devices, with the management server acting as a storage and transmission hub, and the post-processing device handling document information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If documents are transmitted electronically across multiple image processing devices, then transmission efficiency is improved, but document security and integrity are compromised
Solution Approach 1:
The patent introduces a management server as an intermediary between the sender's image processing device and the recipient's image processing device. The management server receives the document data, stores it securely, and distributes it to authorized recipients. This intermediary approach enables efficient electronic transmission while maintaining security through centralized control and authentication mechanisms, directly resolving the contradiction between transmission efficiency and document security.
2Loss of time
If document data is stored centrally for easy access, then retrieval efficiency is improved, but the risk of data loss or unauthorized access increases
Solution Approach 1:
The patent segments the document data into two distinct parts: identifying information (stored with the recipient) and actual document data (stored with the sender or in transmission). This segmentation allows the recipient to quickly retrieve documents by providing only identifying information, while the actual document data remains secure with the sender or in controlled transmission. This resolves the contradiction by enabling fast retrieval without concentrating all data in one vulnerable location.
3Reliability
If specifying information is used to link documents with data parts, then document integrity is improved, but system complexity increases
Solution Approach 1:
The patent uses identifying information as a simplified copy or reference to the actual document data. Instead of transmitting or storing the entire document, the system transmits only the identifying information that uniquely specifies the document. The recipient's device then uses this identifying information to retrieve or access the full document data. This copying approach maintains document integrity through unique identification while avoiding the complexity of managing complete document copies at multiple locations.

AI summary
A system includes:a printing unit that prints a document including a data part;a storage unit that stores (i) specifying information which uniquely specifies the document and (ii) the data part in association with each other;an obtaining unit that obtains the specifying information of the document from a document recipient; anda transmitting unit that transmits the data part corresponding to the obtained specifying information to the document recipient.
