M2M Data License Verification via CSE-Mediated Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing M2M systems lack effective methods to manage and enforce data licenses, leading to uncontrolled data usage and access rights.
Innovation Solution
A method and apparatus for managing data licenses in M2M systems by transferring and checking license information between M2M devices, ensuring operations are performed based on valid licenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If license information is transferred and checked between M2M devices, then data usage control is improved, but system complexity increases
Solution Approach 1:
The patent introduces a Common Service Entity (CSE) as an intermediary to manage license information. The CSE stores license information in a repository and mediates between data providers and data consumers, handling license verification centrally rather than requiring complex peer-to-peer verification logic between all M2M devices. This reduces individual device complexity while maintaining reliable data usage control.
Solution Approach 2:
The patent extracts license information management from the core data transmission path by separating it into a dedicated license management subsystem. License information is stored separately in a CSE repository and retrieved on-demand, rather than being embedded in every data transaction. This extraction simplifies the main data flow while providing comprehensive license control.
2Reliability
If license verification is performed before operations, then data security is improved, but operation speed decreases
Solution Approach 1:
The patent performs license verification as a preliminary action before data operations are executed. The receiving device checks license information in advance by querying the CSE repository and verifying permissions before processing or storing data. This ensures data security is maintained while allowing legitimate operations to proceed efficiently without repeated verification delays.
Solution Approach 2:
The system implements feedback mechanisms where the CSE provides real-time license verification responses to M2M devices. When a device requests license information, the CSE quickly responds with authorization status, enabling the receiving device to make immediate decisions about data operations. This feedback loop maintains security while minimizing verification delays through efficient information exchange.

AI summary
The present invention relates to a method for managing a license of data in a machine-to-machine (M2M) system. A method for operating a M2M device in an M2M system includes: receiving data from a counterpart M2M device; receiving information on a license of the data from the counterpart M2M device; and performing an operation for the data based on the information on the license.
