Distributed Ledger Electronic Document Management System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Setting access authority for each electronic document in an electronic document management system is time-consuming and labor-intensive, especially when a large number of users need to access the documents.
Innovation Solution
An electronic document management system utilizing a distributed ledger, where transactions such as document generation and usage permission are recorded, allowing users to access documents without pre-setting access authority, using a blockchain system with nodes connected via peer-to-peer communication, and employing proof of work to secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access authority is set for each electronic document to manage user access rights, then security and access control are improved, but the time and effort required for administrative work increases significantly
Solution Approach 1:
The system performs preliminary actions by automatically generating access authority settings based on workflow definitions and user roles before users need to access documents. The workflow management server pre-establishes access rules and permissions, eliminating the need for manual configuration each time a document is accessed.
Solution Approach 2:
The system enables self-service by allowing users to access documents through automatically granted permissions based on their roles and the workflow context. Users do not need administrators to manually configure access rights; the system self-manages permission assignment based on predefined workflows and user attributes.
2Reliability
If manual access authority setting is implemented for each electronic document, then precise access control is achieved, but the complexity of system operation increases
Solution Approach 1:
The workflow management server performs multiple functions including workflow definition, user management, and automatic access authority assignment. This universal system handles various access control scenarios through a single unified mechanism, eliminating the need for separate manual configuration processes for each document.
Solution Approach 2:
The workflow management server acts as an intermediary between the document management server and users. It automatically translates user roles and workflow definitions into appropriate access permissions, mediating the complex access control logic without requiring users or administrators to manually configure each permission.
3Reliability
If access authority is pre-configured for each document, then access security is ensured, but the productivity of document access operations decreases
Solution Approach 1:
Access permissions are preliminarily established through workflow definitions and user role assignments before document access operations occur. The system pre-configures access rules based on organizational hierarchy and workflow requirements, enabling rapid document access without real-time permission configuration delays.
Solution Approach 2:
The system enables rapid document access through self-service permission assignment based on user roles and workflow context. Users automatically receive appropriate access permissions without manual intervention, significantly improving document access productivity while maintaining security through role-based access control.

AI summary
An electronic document management system includes plural devices that each store a distributed ledger and are communicably connected to each other, and a transaction generation device that includes a first processor and generates a transaction recorded in the distributed ledger, in which the first processor is configured to generate a document generation transaction in a case where an electronic document is generated and stored in a document management server, the document generation transaction including a document ID for uniquely identifying the electronic document, a transaction ID for uniquely identifying the document generation transaction, and information indicating that the document generation transaction is the document generation transaction, transmit the document generation transaction to the plural devices and record the document generation transaction in the distributed ledger, generate a usage permission transaction in response to a usage permission instruction for permitting a usage user to use the electronic document stored in the document management server, the usage permission transaction including the document ID of the electronic document, a transaction ID for uniquely identifying the usage permission transaction, a usage user ID for uniquely identifying the usage user, a usage permission time at which the usage permission instruction is received, and a parent transaction ID for uniquely identifying a parent transaction that is a transaction related to another process executed on the electronic document related to the usage permission instruction immediately before the usage permission instruction, and transmit the usage permission transaction to the plural devices and record the usage permission transaction in the distributed ledger.
