Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices face challenges with data drift, where changes in data formats and semantics over time can lead to failures in smart contract execution, resulting in invalidations of IoT device-initiated communications.
Innovation Solution
A data drift resolution tool is implemented to generate and dynamically update device records, accounting for changes in data formats and semantics. This tool uses a machine learning algorithm to monitor and validate IoT device communications, ensuring smooth execution of automatic processes and enhancing security by identifying potential unauthorized updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If smart contracts are used to automate IoT device communications, then process automation and security are improved, but data drift causes validation failures and execution failures
Solution Approach 1:
The patent implements a dynamic record-keeping system that automatically updates device parameter records when changes are detected. Instead of using static validation rules, the system continuously adapts to data drift by monitoring incoming data and updating reference records, thereby maintaining validation reliability while preserving automation.
Solution Approach 2:
The system incorporates feedback mechanisms where validation results are used to update device records. When data drift is detected through validation failures, the system learns from these failures and updates its reference records, creating a closed-loop system that improves reliability over time while maintaining automation.
2Reliability
If device records are updated to account for data drift, then validation reliability is improved, but system complexity increases
Solution Approach 1:
The patent implements a self-updating validation system where the device record database automatically updates itself based on incoming data patterns. The system monitors its own validation performance and autonomously adjusts reference records without requiring external intervention or complex manual configuration, thereby improving reliability while minimizing the added complexity burden.
Solution Approach 2:
The patent introduces an intermediary layer between the validation logic and the device records. This intermediary component handles the complexity of record updates and data drift detection, shielding the core validation system from complexity while maintaining high reliability through automated adaptations.
3Object-affected harmful factors
If strict validation is applied to IoT device communications, then security is improved, but network bandwidth and processing resources are wasted due to false rejections
Solution Approach 1:
The patent performs preliminary updates to device records based on detected data drift patterns before strict validation is applied. By proactively adapting validation criteria to match current device behavior, the system maintains security through rigorous validation while avoiding false rejections that would waste network bandwidth and processing resources.
4Device complexity
If static validation rules are used, then system complexity is minimized, but data drift causes execution failures
Solution Approach 1:
The patent transforms static validation rules into a dynamic system where reference records are automatically updated based on detected data drift. This dynamic adaptation allows the system to maintain simple operational procedures while achieving high execution reliability through continuous self-updating of validation criteria.
Data Source
AI summary
A system includes a memory and a processor. The memory stores a baseline record associated with a device, which includes a set of parameters that were extracted from the device. The processor receives a request from the device to initiate a communication. In response to receiving the request to initiate the communication, the processor determines that an update to the device has modified the set of parameters of the device. In response to determining that that the update has modified the set of parameters, the processor extracts the modified set of parameters from the device, and stores a new record associated with the device in the memory, which includes the modified set of parameters extracted from the device. The processor additionally uses the new record to validate the request. In response to validating the request, the processor transmits the communication.
