Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing service layer authorization mechanisms in M2M/IoT systems are typically static, limiting access to only pre-provisioned resources and lacking advanced authorization mechanisms for dynamic permission management, payment-based, barter-based, security-assessment-based, and reputation-based access control.

Innovation Solution

An extensible policy-based service layer dynamic authorization framework that allows registrants to specify consultation-based, payment-based, barter-based, security-assessment-based, and reputation-based dynamic authorization policies, enabling the service layer to dynamically grant or deny access and update static privileges accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If static authorization mechanisms are used, then system simplicity is maintained, but adaptability and flexibility of access control deteriorate

Engineering Contradiction:

Improveauthorization flexibilityVSAvoidauthorization mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic authorization by allowing authorization policies to be modified in real-time based on registrant behavior, context, and criteria. The service layer transitions from static pre-provisioned authorization to dynamic evaluation, where authorization decisions can change during system operation based on evolving conditions and registrant actions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes authorization parameters dynamically by evaluating multiple criteria including registrant reputation, payment status, barter agreements, and security assessments. These parameter changes enable flexible adjustment of authorization levels without requiring complete re-provisioning of the authorization mechanism.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If pre-provisioned access control is implemented, then security management is simplified, but access control flexibility and real-time adaptation deteriorate

Engineering Contradiction:

Improvereal-time policy adaptationVSAvoidpolicy update time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system implements feedback mechanisms where authorization decisions are continuously evaluated based on registrant actions, context changes, and policy criteria. The service layer receives feedback from various sources including reputation systems, payment verification, and security assessments to dynamically adjust authorization in real-time without manual intervention.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Registrants can dynamically update their own authorization privileges through self-service mechanisms. The system automatically evaluates authorization criteria and updates policies without requiring administrator intervention, enabling real-time adaptation while reducing operational overhead and time delays.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If advanced authorization mechanisms are added, then authorization flexibility improves, but system complexity and implementation difficulty worsen

Engineering Contradiction:

Improveauthorization mechanism versatilityVSAvoidsystem implementation ease

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The service layer implements a universal authorization framework that handles multiple authorization types (payment-based, barter-based, reputation-based, security-assessment-based) through a single integrated mechanism. This multi-functional approach provides advanced authorization versatility while avoiding the complexity of implementing separate systems for each authorization type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The service layer acts as an intermediary between registrants and resources, managing complex authorization evaluations centrally. This mediator approach simplifies implementation by consolidating authorization logic in one layer rather than distributing complexity across multiple components, making the system easier to implement while maintaining advanced authorization capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An extensible policy-based service layer dynamic authorization framework can allow a service layer to determine whether or not to grant or deny a registrant access to a resource or service hosted by the service layer for which the registrant currently lacks the proper privileges to access. This method can also enable a service layer to dynamically update its statically configured authorization privileges (by leveraging its dynamic authorization results) such that future requests from the same registrant and to the same resource and service do not require dynamic authorization to be performed.
