Sensor Metadata Matching for IoT Data Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sensor networks have limited data circulation and utilization, leading to duplication of investments and network congestion, as sensing data is primarily used by the owner and not shared effectively with other parties, hindering the creation of value in M2M cloud and IoT systems.
Innovation Solution
A data flow control mechanism is implemented, using a data flow control order generating apparatus that matches sensor metadata with application metadata to optimize the circulation of sensing data, allowing sensors to provide data to multiple applications and enabling efficient data transmission through a sensor managing apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensing data is collected and used only by the sensor owner, then the sensor investment is secure for the owner, but data circulation is limited and network congestion occurs
Solution Approach 1:
The patent implements a data circulation mechanism where sensing data collected by sensors can be utilized by multiple parties beyond just the sensor owner. The system enables data to be shared with third parties and various applications through a standardized interface, allowing the same data resource to serve multiple functions and users simultaneously, thereby improving data circulation without causing network congestion
Solution Approach 2:
The patent introduces a data circulation intermediary system that mediates between sensor owners and data users. This intermediary manages data registration, matching, and transmission, enabling efficient data exchange without direct peer-to-peer connections that would cause network congestion. The intermediary coordinates data flow and maintains system organization
2Ease of manufacture
If sensors are installed by individual owners for their own use, then data collection is simple, but duplication of investment occurs and data sharing is limited
Solution Approach 1:
The patent creates a universal data sharing platform that allows sensing data to be accessed by multiple applications and users. The system enables a single sensor installation to serve multiple purposes and users through standardized data interfaces and circulation mechanisms, eliminating the need for duplicate sensor installations while maintaining ease of original installation
Solution Approach 2:
The patent implements a data copying and distribution mechanism where sensing data can be replicated and distributed to multiple users and applications. Instead of requiring physical duplication of sensors, the system creates digital copies of the sensed data and distributes them through the circulation platform, enabling widespread data access without additional hardware investment
3Reliability
If sensing data is not shared with third parties, then data security is maintained, but value creation in M2M cloud and IoT systems is hindered
Solution Approach 1:
The patent introduces a controlled intermediary system that manages data sharing between sensor owners and third parties. The intermediary implements security protocols, access controls, and authentication mechanisms that protect data security while enabling controlled sharing with authorized third parties for value-creating applications in M2M cloud and IoT systems
Solution Approach 2:
The patent implements differential data sharing where different levels of data access and sharing are provided based on local requirements and authorization. Sensitive data can be protected while less sensitive data can be shared more freely, allowing the system to maintain security where needed while enabling value creation through selective data sharing with third parties

AI summary
There is used a data flow control order generating apparatus that includes: a sensor side metadata acquisition unit acquiring sensor side metadata as information related to a sensor that outputs sensing data; an application side metadata acquisition unit acquiring application side metadata as information related to an application that provides a service by using the sensing data; a matching unit performing matching between the sensor side metadata and the application side metadata to extract the sensor capable of providing the sensing data that satisfies the request of the application; and an instruction unit transmitting a data flow control order that identifies the sensor extracted by the matching unit and the application to a sensor managing apparatus that manages the sensor.
