Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multifunction peripherals (MFPs) lack the necessary hardware or software features for efficient payment processing, relying on methods like campus cards or credit/debit cards, which are not integrated into the devices, leading to inefficiencies in managing document processing transactions.
Innovation Solution
Implementing a distributed blockchain ledger system within MFPs, enabling the use of cryptocurrencies and smart contracts for secure, decentralized payment processing, where users can create and manage digital wallets and contracts for document processing operations, allowing for peer-to-peer transactions and eliminating the need for third-party verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional payment methods (campus cards, credit/debit cards) are used in MFPs, then payment processing can be performed, but the devices lack integrated hardware or software features leading to inefficiencies
Solution Approach 1:
The patent replaces traditional mechanical payment systems (card swiping, physical tokens) with a cryptographic blockchain-based payment system. MFPs use digital wallets and smart contracts to process payments, eliminating the need for integrated card readers or token dispensers while achieving more efficient and secure transaction processing.
Solution Approach 2:
The patent introduces a blockchain network as an intermediary layer between users and MFPs. This decentralized ledger system mediates all payment transactions, providing trust and verification without requiring complex integrated payment hardware in each device. The blockchain acts as a neutral third party that enables seamless peer-to-peer transactions.
2Reliability
If third-party verification is used for transactions, then security can be maintained, but transaction costs increase and processing time is extended
Solution Approach 1:
The patent implements self-service verification through smart contracts that automatically execute transaction validation and fulfillment. The blockchain network enables peer-to-peer verification where nodes collectively validate transactions through consensus mechanisms, eliminating the need for centralized third-party verification. This automated self-service approach maintains high security while dramatically reducing processing time and costs.
Solution Approach 2:
The patent incorporates real-time feedback mechanisms through the blockchain network, where transaction status, verification results, and ledger updates are immediately propagated to all participants. This continuous feedback loop enables rapid consensus achievement and instant transaction confirmation, reducing waiting time while maintaining rigorous security standards through multiple verification layers.
3Ease of operation
If third-party payment processors are used, then transactions can be facilitated, but transaction costs increase
Solution Approach 1:
The patent extracts the payment processing function from traditional third-party intermediaries and relocates it to the decentralized blockchain network. By removing the centralized payment processor layer, the system eliminates associated fees and costs while maintaining transaction facilitation capabilities. Users interact directly with the blockchain through digital wallets, bypassing traditional payment gateways and their associated cost structures.
Data Source
AI summary
A system and method for blockchain-based document processing includes a processor, network interface, print engine, scan engine, and a memory storing a blockchain ledger. The blockchain ledger includes time stamped blocks, each block including currency data associated with a digital currency value. The processor generates a block corresponding to a received instruction, a preexisting currency value associated with the received instruction and contract data corresponding to a smart contract associated with the received instruction. The processor updates the blockchain ledger with a generated block and shares an updated blockchain ledger with other networked data devices via the network interface. The processor also receives verification of the updated blockchain ledger from the other networked data devices. The processor executes the smart contract upon receipt of verification.
