Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for device-to-person association lack transparency and security, making it difficult to verify device ownership and usage, especially in critical fields like medicine and law enforcement, and are vulnerable to fraud and security breaches.
Innovation Solution
A device association management system utilizing a digital distributed ledger with a certificate authority to authenticate devices and persons, issuing digital certificates and recording transactions securely, ensuring immutability and transparency of device associations through blockchain technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional manual processes and traditional databases are used for device association, then system complexity is reduced, but transparency and verification capability are insufficient
Solution Approach 1:
The patent introduces a distributed ledger as an intermediary between devices and persons, which transparently records and verifies device associations. The ledger acts as a neutral mediator that all parties can trust, eliminating the need for complex manual verification processes while providing complete transparency of device ownership and usage history.
Solution Approach 2:
The patent replaces manual mechanical processes (physical device tagging, paper records, manual verification) with cryptographic and distributed ledger mechanisms. Digital certificates, cryptographic signatures, and consensus algorithms substitute for manual authentication, providing automated transparency without proportionally increasing system complexity.
2Reliability
If multiple conventional security measures are employed for transaction security, then security coverage is increased, but verification of transaction integrity becomes difficult and complexity increases
Solution Approach 1:
The patent merges multiple security functions (authentication, authorization, encryption, integrity verification) into a unified distributed ledger security model. All transactions are secured through a single consensus mechanism and cryptographic framework, eliminating the need for multiple separate security layers while maintaining or enhancing overall security reliability.
Solution Approach 2:
The distributed ledger provides continuous feedback on transaction integrity through its immutable record-keeping and consensus verification. Each transaction is verified by network nodes and permanently recorded, providing immediate feedback on whether a transaction is valid and has been compromised, eliminating the difficulty of verifying transaction integrity that plagues conventional multi-layer security systems.
3Loss of information
If conventional databases are used for device association records, then ease of operation is maintained, but transparency and visibility for verification are insufficient
Solution Approach 1:
The distributed ledger serves multiple functions simultaneously: it acts as a database for storing device associations, a verification system for transparency, and a security layer for protecting records. This universal system replaces conventional databases while providing enhanced visibility and verification capabilities without significantly complicating operations, as the same ledger interface handles both storage and verification.

AI summary
An association management system for establishing, maintaining, and monitoring associations between a personal identifier and an electronic device, includes a provider subsystem in operable communication with at least one of the personal identifier and the electronic device. The provider subsystem is configured to provision a person associated with the personal identifier, authenticate both of the personal identifier and the electronic device, and establish an association of the authenticated personal identifier to the authenticated electronic device. The system further includes a certificate authority subsystem for issuing at least one digital certificate to verify an identity of one or more digital entities operating on the management system, and a digital distributed ledger including a plurality of a consensus pool of participating processors. The digital distributed ledger is configured to verify, using the at least one digital certificate, transaction events of the association management system.
