Blockchain Job Management for Image Forming Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming devices lack an efficient and decentralized method for managing and recording job information, relying on central servers which can lead to data integrity issues and increased storage costs due to the need for separate servers for storing user job information.
Innovation Solution
Implementing a blockchain-based distributed ledger system where multiple nodes manage and record job information, allowing users to access and update job lists across a network of image forming devices, enabling secure and decentralized storage and retrieval of job data without relying on a central server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a central server is used to manage job information, then data storage and management is simplified, but data integrity issues arise and storage costs increase due to the need for separate servers
Solution Approach 1:
The patent segments the centralized job information management system into multiple distributed nodes, each maintaining its own copy of the ledger. This segmentation eliminates the single point of failure inherent in centralized systems while distributing storage responsibilities across the network, thereby improving both reliability and data integrity without requiring separate dedicated servers.
Solution Approach 2:
The patent introduces a blockchain intermediary layer that mediates between users and the job information storage system. This blockchain ledger acts as a trusted intermediary that validates and records job information transactions, ensuring data integrity through cryptographic verification while reducing the need for separate storage servers by leveraging the distributed network infrastructure.
2Reliability
If separate servers are used for storing user job information, then data security is improved, but storage costs increase
Solution Approach 1:
The patent merges the storage function with the computational network infrastructure by implementing a distributed ledger across existing nodes. Instead of combining separate storage servers with security systems, the blockchain technology combines storage, security validation, and network communication into a unified distributed system, eliminating redundant storage resources while maintaining enhanced security through cryptographic mechanisms.
Solution Approach 2:
The patent makes each network node universal by enabling it to perform multiple functions: storing job information, validating transactions, maintaining security, and participating in consensus. This multi-functionality eliminates the need for dedicated separate servers, as existing network infrastructure can handle storage and security tasks simultaneously, reducing overall storage resource requirements while maintaining or improving data security.
3Reliability
If a decentralized system is implemented, then data integrity is improved, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms through the blockchain consensus protocol, where each node continuously validates and cross-checks job information against the distributed ledger. This automated feedback loop ensures data integrity by comparing transactions across multiple nodes and rejecting inconsistencies, thereby maintaining high reliability while managing system complexity through algorithmic validation rather than manual coordination.

AI summary
An image forming device and an operating method of an image forming device are provided. The operating method includes receiving first authentication information corresponding to an account of a first user, when the account of the first user is authenticated according to the first authentication information, preparing an operation of the image forming device according to usage authorization of the first user; receiving a request to provide job information of the first user, obtaining a first job list of the first user from a ledger on which job information of a user with respect to a certain image forming job is recorded, based on a blockchain in which the ledger is distributed and managed, and performing a first image forming job selected from the first job list.
