Trust Platform for Device Access Screening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network providers and institutions lack information about the trustworthiness of user devices requesting access to their networks, leading to potential security issues and negative impacts on network performance.
Innovation Solution
A trust platform is introduced that enables entities to determine the trustworthiness of user devices and networks by receiving scores and feedback from multiple sources, allowing for the derivation of composite trust scores and enabling appropriate actions such as blacklisting or restricting access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network providers allow unrestricted access to user devices, then network availability and ease of connection are improved, but network security and performance deteriorate due to inappropriate activities
Solution Approach 1:
The system performs preliminary actions by establishing a communication session before allowing network access. The first device monitors the second device's activities during this preliminary session and only grants network access if appropriate behavior is observed, preventing inappropriate activities before they can impact the network.
Solution Approach 2:
The system implements feedback mechanisms where the first device continuously monitors the second device's activities and adjusts access permissions accordingly. If inappropriate activities are detected, the system provides feedback by terminating the communication session or restricting network access, creating a closed-loop security system.
2Reliability
If network providers implement monitoring of user device activities, then network security is improved, but device complexity and operational overhead increase
Solution Approach 1:
The system enables self-service monitoring where the second device itself reports its activities to the first device during the communication session. This peer-to-peer monitoring approach reduces the complexity of centralized monitoring systems while maintaining effective security oversight.
Solution Approach 2:
The system extracts only the essential monitoring functions from complex security systems. Instead of implementing comprehensive monitoring infrastructure, the patent extracts the core function of activity detection and reporting, implementing it through simple communication protocols between devices.
3Reliability
If financial institutions perform thorough credit checks and transaction monitoring, then credit risk is reduced, but processing time and transaction throughput decrease
Solution Approach 1:
The system performs preliminary credit risk assessment by monitoring device activities during the communication session establishment phase. This preliminary action provides risk information before transactions occur, allowing financial institutions to make credit decisions without delaying transaction processing.
Solution Approach 2:
The system introduces a trust platform as an intermediary that handles credit risk assessment and transaction monitoring. This intermediary component separates risk evaluation functions from transaction processing, allowing thorough credit checks to be performed independently without blocking transaction throughput.

AI summary
A first user device may receive, from a second user device, a request to communicatively couple to the first user device, and may establish a communication session with the second user device after receiving the request. The first user device may identify, after establishing the communication session, an inappropriate activity of the second user device relating to the communication session, and perform a set of actions based on identifying the inappropriate activity. The set of actions may include causing the communication session to be restricted, and providing, to a trust platform, a score for the second user device. The score may permit the trust platform to derive a composite score, indicative of a level of trustworthiness of the second user device, that enables other user devices, associated with the trust platform, to determine whether to grant access requests submitted by the second user device.
