Communication Trust Assessment and Privacy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in ensuring privacy and trustworthiness of communication sessions, particularly in determining whether the next hop network is trusted, which is crucial for applying privacy procedures as defined in RFC3325, such as removing the P-Asserted-Identity header when privacy is requested.
Innovation Solution
A method and system that determine the address associated with the called party to assess if they are in a trusted network, controlling communication based on this assessment, and ensuring a secure connection is established before transmitting messages, with mechanisms to discard or modify messages if the next hop network is not trusted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication is allowed between any networks, then communication productivity is improved, but privacy security deteriorates
Solution Approach 1:
The patent applies preliminary action by determining whether the next hop network is trusted before allowing communication to proceed. The method evaluates trustworthiness in advance using predefined criteria (internal network status, external network status, service level agreements) and only permits communication if the network is deemed trusted, thus preventing privacy breaches before they can occur
Solution Approach 2:
The patent introduces an intermediary trust determination mechanism that acts as a mediator between communication requests and network transmission. This intermediary layer evaluates multiple factors including internal network trust status, external network trust status, and service level agreement compliance to decide whether to allow communication, thereby protecting privacy without completely blocking communication
2Reliability
If privacy procedures are applied by removing P-Asserted-Identity header, then user privacy is protected, but information completeness deteriorates
Solution Approach 1:
The patent applies local quality by selectively removing the P-Asserted-Identity header only in specific circumstances where privacy is required, rather than universally removing all identifying information. The method removes this specific header element while preserving other communication information, thus protecting user privacy locally where needed without causing comprehensive information loss
Solution Approach 2:
The patent implements discarding and recovering by selectively discarding the P-Asserted-Identity header when privacy procedures are triggered, while maintaining the ability to recover or preserve other essential communication information. This selective discarding approach protects privacy while minimizing information loss

AI summary
A method of communication between a calling party in a first network and a called party in a second network is disclosed. The method comprises determining in the first network an address associated with the called party. The method also comprises determining, based on the address, if the called party is in a trusted network, and controlling the communication between the called party and the calling party in dependence on if the called party is in a trusted network.
