Token-Based Arbiter for Priority Resource Arbitration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively prioritize access to shared resources like surveillance cameras and traffic light controllers among multiple first responders over the Internet or distributed networks, leading to potential conflicts and inefficiencies in resource allocation.
Innovation Solution
A token-based arbiter system that embeds priority and preemptive metrics into secured tokens, allowing the system to determine and enforce access rights based on user authorization, authentication, and predefined policies, ensuring that only the highest-priority user gains exclusive access to limited resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple first responders access shared resources simultaneously over the Internet, then resource availability increases, but access conflicts and allocation inefficiencies occur
Solution Approach 1:
The system performs preliminary actions by embedding priority metrics and authorization attributes into secured tokens before users access resources. The identity provider pre-calculates priority levels based on authorization attributes, and the arbiter pre-establishes access rules based on these metrics, resolving conflicts before they occur rather than managing them in real-time
Solution Approach 2:
The token-based arbiter acts as an intermediary between the identity provider and resource access system. It receives secured tokens with embedded priority metrics, evaluates these metrics against access rules, and determines exclusive access rights without requiring direct complex interactions between multiple users and resources
2Productivity
If priority-based access control is implemented, then resource allocation efficiency improves, but system complexity increases
Solution Approach 1:
The secured token serves multiple functions: it authenticates user identity, authorizes access rights, and carries priority metrics for arbitration. The identity provider performs both authentication and priority calculation, while the arbiter evaluates both authorization attributes and priority metrics within a single access control framework, reducing the need for separate systems
Solution Approach 2:
The system changes parameters by embedding dynamic priority metrics into static secured tokens. The priority level is determined by authorization attributes and can be recalculated and reissued when conditions change, allowing flexible resource allocation without restructuring the entire access control system

AI summary
An apparatus and method for employing a token based arbiter. The apparatus includes a priority provider (26) comprising a processor for calculating an arbiter metric and an identity provider (18) having a processor for embedding the metric into a secured token. The apparatus also comprises memory coupled to the processor having one or more instructions executable at the processor. The processor is operable when executing the instructions to: collect authorization attributes (A) from one or more users seeking use of a resource (20) associated with a service provider; determine the level of priority to the one or more users based on prescribed policy of the priority provider; assign at least one arbiter metric (22, 32) to a secured token (T) for each of the one or more users based on the level of priority identified by the priority provider.
