Secure Server ID Mapping for Mixed Group Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public Safety communication systems face challenges in securely incorporating guest users into existing communication groups without compromising the security and privacy of permanent members, as current systems are inflexible and time-consuming, often leading to delayed inclusion due to security concerns.
Innovation Solution
A method that assigns temporary IDs to protected users and limited group rights to guest users, allowing controlled visibility of permanent IDs, with a secure server managing ID mapping and expiration rules to ensure privacy and security during mixed group communication sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security procedures are implemented to protect permanent member information, then security and privacy are improved, but the time required to include guest users increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing security policies, ID mapping rules, and access control configurations before guest users need to be included. The secure server is pre-configured with the ability to map permanent IDs to temporary IDs and enforce visibility rules, so that when a guest user needs to be added, the security framework is already in place and only the specific guest user needs to be onboarded, not the entire security infrastructure.
Solution Approach 2:
The patent introduces temporary IDs as an intermediary layer between permanent member IDs and guest users. This intermediary mechanism allows guest users to access and communicate with permanent members without directly exposing or knowing the permanent IDs. The secure server acts as a mediator that translates between temporary IDs (visible to guests) and permanent IDs (protected), enabling secure communication while maintaining privacy.
2Loss of information
If permanent IDs are hidden from guest users, then privacy of permanent members is improved, but the ability to communicate with specific users deteriorates
Solution Approach 1:
Temporary IDs serve as an intermediary that preserves privacy while enabling communication. Guest users can communicate with permanent members using temporary IDs without knowing or exposing the permanent IDs. The secure server mediates all communications, translating temporary IDs to permanent IDs behind the scenes, thus maintaining both privacy and communication capability.
Solution Approach 2:
The system creates temporary ID copies that represent permanent members in the guest user interface. These temporary IDs are functional copies that enable communication and group participation without revealing the original permanent IDs. The mapping between temporary and permanent IDs is maintained by the secure server, allowing the copy to fulfill the communication function while protecting the original identifier.

AI summary
A method of providing a mixed group communication session for a mixed group containing protected users and a guest user is provided. The method uses a secure server to assign temporary Identities (IDs) to the protected users. The secure server forms a mixed group session containing desired participants from among the protected users and the guest user. The secure server provides limited group rights to the guest user in the mixed group session. During the mixed group session, the secure server uses the permanent IDs of the protected users towards other protected users and temporary IDs of the permanent users towards the guest user. Also provided is a method for providing a mixed group communication session for a mixed group containing protected users and a guest user, wherein temporary IDs are assigned to protected users and the guest user.
