Innovation Solution
A method utilizing temporary identifiers and smart contracts with blockchain ledger recordation for secure and trusted mobility transactions, enabling seamless access and communication among participants by assigning temporary identifiers to endpoint devices, with rules defined by service providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual assurance and validation processes are used for personnel authentication, then security and authorization are ensured, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system performs preliminary authentication and authorization by verifying personnel credentials against the blockchain ledger before issuing temporary identifiers. This advance validation ensures security requirements are met while enabling rapid access during emergencies, resolving the contradiction between thorough authentication and time efficiency.
Solution Approach 2:
The patent introduces temporary identifiers as intermediary tokens that mediate between personnel authentication and system access. These identifiers serve as a time-efficient proxy for full credential verification, allowing rapid access while maintaining security through blockchain-verified authorization records.
2Productivity
If temporary identifiers are assigned to endpoint devices for rapid access, then response speed and efficiency are improved, but system security and access control complexity increase
Solution Approach 1:
The system creates simplified copies of authentication credentials in the form of temporary identifiers that can be rapidly issued and verified. These identifier copies enable fast access control without requiring complex real-time credential verification, thus improving productivity while managing system complexity through standardized token-based access.
3Reliability
If blockchain ledger recordation is implemented for transaction logging, then auditability and trust are enhanced, but system complexity and computational requirements increase
Solution Approach 1:
The patent extracts the complex blockchain verification and recordation functions into a separate, dedicated processing layer. This extraction allows the core access control system to remain relatively simple while benefiting from enhanced auditability through blockchain technology. The complex operations are isolated to specific modules that handle ledger interactions, reducing overall system complexity.

AI summary
A processing system including at least one processor may obtain at least a first identifier associated with an endpoint device of a user at a location, determine, based on the at least the first identifier, that the user is an authorized participant of at least one service at the location, and provide an identity token to the endpoint device, where the identity token is for use at the location in connection with the at least one service, provide to the endpoint device a list of other identity tokens associated with endpoint devices of other users at the location, detect a communication between the endpoint device of the user and an endpoint device of the other user in accordance with the identity token and another identity token, from among the other identity tokens, and record information characterizing the communication in an electronic ledger associated with the at least one service.
