Distributed Device Rating System Using Real-Time Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rating systems for devices in distributed computing systems rely on manual human input, which is subjective and static, making them inaccurate for assessing the trustworthiness and capabilities of devices involved in transactions, especially as devices change ownership or are re-instantiated.
Innovation Solution
A distributed device rating system that uses a central trusted authority system to provide real-time ratings based on previous transactions, allowing devices to query and aggregate ratings from other devices within the network to determine the trustworthiness and capabilities of candidate devices for transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual human input is used for ratings, then the system is simple to operate, but the ratings become subjective and static, reducing accuracy for assessing device trustworthiness
Solution Approach 1:
The system enables devices to automatically query and aggregate ratings from other devices without human intervention. Each device autonomously performs rating queries to candidate devices, collects ratings, and determines trustworthiness automatically, eliminating the need for manual human input while maintaining accurate assessments
Solution Approach 2:
The system implements a feedback mechanism where devices provide ratings about their transaction experiences with candidate devices. These ratings are collected by querying devices and aggregated to provide real-time feedback on device trustworthiness and capabilities, enabling continuous improvement of assessment accuracy
2Reliability
If manual ratings are used, then the system requires less automation, but the ratings cannot reflect real-time performance and reliability
Solution Approach 1:
The system performs rating queries to candidate devices before transactions are executed. By conducting these assessment actions in advance, the system ensures that devices are evaluated on their actual performance and reliability prior to engagement, enabling reliable trustworthiness assessment
Solution Approach 2:
Devices automatically perform rating queries and collect feedback from other devices without human intervention. The automated rating collection process continuously updates device profiles with real-time performance data, enabling accurate and timely trustworthiness assessments
3Adaptability or versatility
If devices change ownership or are re-instantiated, then system adaptability is improved, but existing static ratings become inaccurate
Solution Approach 1:
The system transitions from static ratings to dynamic, real-time ratings that continuously update based on current device performance. When devices change ownership or are re-instantiated, the system queries for updated ratings that reflect their current state, ensuring accuracy remains maintained despite changes
Solution Approach 2:
The system continuously collects feedback from devices about their performance and reliability. This ongoing feedback mechanism ensures that ratings are always current and accurate, automatically adapting to device changes, ownership transfers, or re-instantiation without compromising rating precision

AI summary
A distributed device rating system includes a device that is configured to send, to a central authority system, a query to identify at least one other device with which to perform a transaction, where the query specifies one or more criteria associated with the transaction, receive, from the central authority system, an identification of one or more candidate devices with which to perform the transaction, receive rating information associated with the one or more candidate devices, where the rating information identifies at least one characteristic of services previously performed by the one or more candidate devices, determine whether the rating information associated with at least one candidate device of the one or more candidate devices satisfies a rating threshold, and, responsive to determining that the rating information satisfies the rating threshold, initiate, with the at least one candidate device, performance of the transaction.
