Trusted Chain Payment Network Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current payment device systems fail to securely share and utilize sensitive information within trusted networks, limiting the ability of non-holders to access benefits and options, and expose sensitive data to other members.
Innovation Solution
A method and system utilizing trusted chains and linked lists to create a local trust network where sensitive information is protected, allowing network members to request and respond to payment device options securely, facilitating transactions without sharing privileged information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If payment device information is shared within the trusted network to enable non-holders to access benefits, then payment device options and benefits are maximized for network members, but sensitive data security is compromised and exposed to other members
Solution Approach 1:
The trusted chain is segmented into multiple data cells, where each cell contains specific payment device information for a particular member. This segmentation allows the system to share payment device options and benefits across the network while maintaining granular control over which specific information is accessible to whom, thus preventing exposure of sensitive data.
Solution Approach 2:
The trusted chain acts as an intermediary data structure that enables indirect sharing of payment device information. Instead of direct sharing between members which would expose sensitive data, the trusted chain mediates the information flow, allowing non-holders to access benefits through the structured, verified data cells without direct exposure to underlying sensitive information.
2Object-affected harmful factors
If sensitive payment device information is classified and protected from other members, then data security is maintained, but non-holders lose the opportunity to receive benefits bestowed to payment device holders
Solution Approach 1:
The system creates copies of payment device information in the form of data cells within the trusted chain. These copies contain the necessary information to enable non-holders to access benefits and options without requiring access to the original sensitive payment device data. The copies are structured to provide functionality while maintaining security of the source information.
Solution Approach 2:
The solution moves the information sharing problem to another dimension by using a distributed trusted chain structure. Instead of sharing information horizontally across members (which creates security risks), the system organizes information vertically in chained data cells with cryptographic verification, enabling benefit sharing while maintaining security boundaries.
3Productivity
If payment device information is made accessible to determine interest rates and rewards, then payment device options are optimized, but the risk of sensitive information exposure to unauthorized members increases
Solution Approach 1:
The trusted chain is pre-structured with data cells containing payment device information before any transactions occur. Cryptographic verification mechanisms are established in advance, and the chain is configured to automatically verify and control information access. This preliminary setup enables efficient determination of interest rates and rewards while ensuring security protocols are already in place to prevent unauthorized access.

AI summary
Techniques are described with respect to a system, method, and computer product for maximizing payment options. An associated method includes generating a trusted chain comprising a plurality of data cells, the data cells including at least payment device data of a payment device associated with a user within a trusted network; transmitting a broadcast message to the plurality of data cells based on a selection of an option of the payment device, the broadcast message indicating occurrence of a transaction event within the trusted network involving the option; and generate a sub-chain of the trusted chain associated with the transaction event relating to the option. The method further including selecting the data cell of the plurality data cells comprising payment device data associated with the sub-chain; and closing the sub-chain based on a detected completion of the transaction event.
